Download iPhone Custom Firmware 3.1.3 (IPSW)

You would know by now that apple has pushed iPhone firmware update: iPhone OS 3.1.3 for iPhone and iPod Touches. Almost all the Jailbreak tools like RedSn0w, PwnageTool and Sn0wbreeze has also been updated to jailbreak iPhone OS 3.1.3 but GeoHot is showing to interest in updating BlackRa1n and BlackSn0w to jailbreak and unlock iPhone firmware 3.1.3.

You can jailbreak iPhone 3.1.3 by creating Custom firmware IPSW file using PwnageTool 3.1.5. Which is considered the best way to jailbreak iPhone and iPod Touch but the PwnageTool is available for Mac only. So, only Mac users are able to create custom firmware 3.1.3 using PwnageTool. What if you’re on Windows? and do not own a Mac or don’t want to go through the PwnageTool procedure?? if so, this topic is for you.

Here you can download iPhone OS 3.1.3 Custom firmware for iPhone 3GS, iPhone 3G and iPhone 2G. These custom firmware 3.1.3 are created with PwnageTool and can be restored via iTunes. (Download links below)


There are two types of Custom Firmwares available for download below.

  1. ACTIVATED: This custom IPSW file is for users who want to unlock their iPhone which means they are NOT on Official Carrier.
  2. NOT ACTIVATED: This custom IPSW file is for users who are on Official Carrier only.

So make your choice wisely. You’ll know whether you made the right choice or not once you successfully get the Signals or could Not.

iPhone 3GS users: If you’re an iPhone 3GS user, You’re strongly advised not to play with your 3GS if you depends on unlock because BlackSn0w does NOT work either if you’re on Baseband 05.11.07 (older) and restore with this custom firmware.. you’ve been warned. please note that it works for old Bootrom models only. Don’t even bother trying them if you’re already @ OS 3.1.3.

How to Install iPhone Custom Firmware 3.1.3

  1. Download custom firmware (IPSW) (all parts) for your device from links below.
  2. Join the splitted custom IPSW file by unpacking them:
    • Mac Users: use BetterZip ( or what ever you want )
    • Windows Users: use HJSplit ( or what ever you want)
  3. Put iPhone in recovery mode. (How to: put iPhone into Recovery Mode)
  4. Press the Shift key for Windows or ALT for Mac and click restore and use the custom IPSW.
  5. It will start restoring your iPhone which may take 10mins and will jailbreak iPhone. (iPhone 2G users are done here >Jailbreak+Unlock<. enjoy OS 3.1.3)
  6. iPhone 3GS and 3G users who want to unlock iPhone needs to install UltraSn0w using following guide:

    How to: Unlock iPhone 3GS and 3G using UltraSn0w (This works for OS 3.1.3 as well)

Will this also work on 3GS with updated bootroom.
Or will blackra1n always be needed to restart phone after powerdown/reboot.

iPhoneHeat February 12, 2010, 8:43 pm

Don’t play with your new BootRom 3GS 🙂
anything goes wrong and you’re stuck..
tethered boot is the only and best options for you ATM

Leeuwtje February 12, 2010, 8:46 pm

Thanx, will stick to blackra1ned 3.1.2. For now anywayz, till something better comes along.

Saddy February 12, 2010, 9:02 pm

Will the above mentioned procedure also unlock iphone 3g with baseband 05.12.01.

iPhoneHeat February 13, 2010, 10:43 am

nope.. Baseband 05.12.01 is NOT unlockable ATM

vankoo February 12, 2010, 9:25 pm

Thanks.. it will help windows users like me.

KING Ayub February 12, 2010, 11:46 pm

Thanks For This But Also upload Custom Firmware 3.1.3 For Ipod Touches.

hellodrsoul February 13, 2010, 2:21 am

Super Thanks sir.i was waiting for these files from the day you said ‘get custom IPSW files first from kept your promise.
Thanks again.

Saddy Replieing February 13, 2010, 5:30 am

Saddy no it will not it will reserve your baseband that u currently have only.

ec.sorivong February 13, 2010, 9:02 am

Hi All,

I have downloaded the OS 3.1.3 activated from the provided link. After the restoration via iTune, it got the error with code 1604.

iPhoneHeat February 13, 2010, 10:49 am

use iReb…
more details on its way

Amin12307 February 15, 2010, 10:12 pm

what about the new iphone 3gs it IReb doesn’t support it.

jward017 February 17, 2010, 6:14 am

You need ih8sn0w to bypass this

Saddy February 13, 2010, 10:53 am

🙁 Thanks guys for the update, i wish the unlock to 5.12.01 will be released soon. I visit this website 50 times in a day hoping for some good news.

Johnn_Lewis February 13, 2010, 5:01 pm

Hi there,
Ive got an iPhone 3GS with 3.1.3 not jailbreak (updated forgetting had jailbreak on it!) so now im stuck with baseband 05.12.01 although I do have an old bootrom and old MC model (got it in July 08) this sounds ideal if it would work although unfortunately I can’t download the firmwares, could you please upload them to mediafire or something cause I cant get them.
Very much appreaciated.

iPhoneHeat February 13, 2010, 10:16 pm

you need to downgrade firmware first.. you can do that for 3GS only if you’ve SHSH saved at Saurik server

Johnn_Lewis February 14, 2010, 3:24 am

ooh. Well I haven’t done that and have already reseted to 3.1.3. Any way I could restore to a custom firmware of 3.1.2 or jailbreak 3.1.3 without that SHSH Server thing? Or Am I stuck until a jailbreak from scratch for 3.1.3 comes along

iPhoneHeat February 14, 2010, 2:58 pm

you cannot restore older firmware w/o SHSH..

Johnn_Lewis February 14, 2010, 3:18 pm

So can I not jailbreak my iPhone 3GS 3.1.3 with baseband 05.12.01 without having a jailbreak already? Cause its gives me 16xx errors and I cant use iREB for Windows as its not compatible with iPhone 3GS yet. Any ideas?

For a summary. My iPhone 3GS is on 3.1.3 with baseband 05.12.01 and currently not jailbroken so any ideas would be fab(: !

Amin12307 February 15, 2010, 12:19 pm

If u find an answer to your question plZ
tell it to me, too.

Johnn_Lewis February 15, 2010, 5:37 pm

sure i will. So anyone nice here at iPhone Heat tell me if you can jailbreak iPhone 3GS 3.1.3 Baseband 05.12.01 AND was accidently upgraded to the stock firmware losing my jailbreak? Also it is the old bootrom and non mc model im using which is fortunate for me! Please, please, please help us. This is the best website I know of updates on jailbreaking and I constantly check on a little light :)).
Thank you.

iPhoneHeat February 15, 2010, 9:46 pm

You can NOT unlock baseband 05.12.01 ATM. wait for a solution to come out..
@ jailbreak.. downgrade your firmware to 3.1.2 if you have SHSH saved at saurik server then use 3.1.2 jailbreak tool

Amin12307 February 15, 2010, 10:08 pm

reminder just iphone 3gs

Amin12307 February 15, 2010, 10:11 pm

if i could stop error 21 between restoring my iphone my jailbreak is going to work but i cannot fix it. if i find an answer i’m going to tell u guys.

Johnn_Lewis February 16, 2010, 4:38 am

Same, if only iH8sn0w would upgrade the iREB so it would work with every ipod touch and every iphone then it would be grand. But I keep getting errors when Im doing these tries. Any other programs that will get rid of these errors and let us jailbreak! Is there any way to jailbreak successfully with 3.1.3 stock firmware on 3GS?
Please reply and heeelp me 🙂
thank you.

Amin12307 February 17, 2010, 4:57 am

i think u need to wait to 4.0 os.

ricky1717 February 13, 2010, 8:14 pm

After alot of different tries I finally got this to work on my iphone 2g thanks Iphoneheat!Works great!

MASOOD February 13, 2010, 9:36 pm

iPhoneHeat February 13, 2010, 10:20 pm

3.1.3 is NOT unlockable ATM… because it updates baseband to 05.12.01 which is not unlockable

Amin12307 February 17, 2010, 4:58 am

do you have jailbreak on it.

A1varo February 14, 2010, 6:25 am

Testing all devices

bobjohnson February 16, 2010, 8:45 am

I downloaded the file and says check for update when I am in restore mode. I am afraid to hit yes, and it auto updates my phone. If I hit cancel it doesn’t allow my phone to show up.

Amin12307 February 17, 2010, 4:51 am

If your an Iphone 3gs user and on 3.1.2 u should rejailbreak your iphone/ipod touch, with the program that u jailbreak it, it should fix it for u if it does not work.

try to hold shift (pc) or ali/option (mac) and then click restore and choose the frimave that u have right now not the 3.1.3 frimave.


montedubedition February 16, 2010, 9:19 am

amin12307 February 18, 2010, 5:25 am

samsunga February 19, 2010, 1:09 am

i’m still on 3g OS 3.0 baseband 4.26. what’s the best thing for me to do? upgrade to 3.1.2 or 3.1.3? also is there any point in sticking with baseband 4.26 anymore? thanks

iPhoneHeat February 19, 2010, 1:51 am

baseband 4.26 is the most favorable one to stay with..
Use custom firmware 3.1.2 avoid 3.1.3 because there’s nothing special in it

Hi.. Saw your site bouncing around. I have iPhone 3g version 2.2.1 and all apps require 3.0. I originally unlocked and jailbroke but it has been a while. Some say I need Blackra1n and have downloaded and another says redsnow. Can you explain. I don’t need to unlock since it is previously working right. I have t-mobile.

iPhoneHeat February 23, 2010, 2:24 pm

Use the custom firmware 3.1.2 (can be found under iPhone firmwares category)
I’m talking about 3.1.2… NOT 3.1.3
then unlock using ultraSn0w

Boaz February 24, 2010, 3:41 pm

i have active iphone and i didnt stupid thing and update to 3.1.3 🙁 with new 05.12.01.

I desperately need to jailbreak
Will someone tell me why this jailbreak wont work

fuinax February 26, 2010, 2:50 am

Are the IPSW’s with Apple start logo or customised logo ?

Thx !

iPhoneHeat February 26, 2010, 10:02 pm

default logos

ahniu March 1, 2010, 8:29 am

I’m running jailbreak 3.0 with baseband 04.26.08. iPhoneHeat recommended using custom firmware 3.1.2 and retain baseband 04.26.08. If I use custom firmware 3.1.3, will I retain baseband 04.26.08 ??

ahniu March 1, 2010, 8:30 am

Forgot to mention, I’m running 3GS.

iPhoneHeat March 1, 2010, 9:40 pm

Don’t try anything on your 3GS at the moment… try any custom firmware only if you’ve SHSH cert saved at Saurik server via CYDIA..
If not You better stay with 3.0

vesh March 5, 2010, 8:34 am

i just bought 3gs iphone 32gb with 3.1.2 version. but the problem is everytime i on my iphone its working good but once i turn it off ,n turn on again it shows usb cable connected with itunes. does anybody knows what is the problem for this? another thing ipod application is missing.

iPhoneHeat March 5, 2010, 3:12 pm

It means you iPhone is tethered jailbreak.. you need to connect to computer and run the jailbreak software like BlackRa1n to get to the Home screen..

If you depend on unlock or want to keep the jailbreak.. you better not play with your iPhone firmware..

vesh March 5, 2010, 9:07 pm

all 3gs iphone with version 3.1.2 has same problem or only my iphone is tethered jailbreak. can you make me clear about tethered jailbreak? what does it mean? do i need to download jailbreak software like BlackRa1n in my computer before i connect my iphone to computer? why it is tethered jailbreak? and how can i get the ipod application in homescreen? ipod application is missing.

iPhoneHeat March 5, 2010, 9:19 pm

don’t know what happened to the iPod thingy..
YES all 3GS are tethered jailbreak only which means when you reboot your iPhone it will stuck at recovery screen asking for restore.. Don’t do that
simply connect to computer and run the BlackRa1n.. yes you need blackra1n in your PC/Mac

tip: don’t play with iPhone firmware at a time when there’s updated firmware available .. anything went wrong and you’ll be forced to upgrade to 3.1.3 which is not yet unlockable @ baseband 05.12.01

fullforcesrt4 March 5, 2010, 9:09 am

ok so do u guys think there will be a jail break and unlock for 3.1.3 baseband 5.12.01 any time soon??

iBanja March 9, 2010, 1:23 am

I installed 3.1.3 custom firmware on 3GS iPhone with 5.11 basebend and problem is with unlock. I tried with blacksn0w with no luck just freeze….

Please any suggestion.

t_u_k_2k3 March 22, 2010, 2:56 pm

Dogge March 22, 2010, 5:30 pm

Hi there.
First i must say im sorry if this question seems weird, but i better ask before i do any crazy things.
I have a Iphone 3GS, Baseband 05.12.01, Bootloader 6.4, Model MC 133.
Can i use iPhone2_1_3.1.3_7E18_Custom_Restore_NOT_Activated to have a chanse to use those apps i want? I dont need a unlook now, my phone is locked.

I have read a lot but im not a technical guy.


iPhoneHeat March 22, 2010, 6:48 pm

Your baseband shows that you are on latest firmware 3.1.3… you can jailbreak only by downgrading to OS 3.1.2. and you can downgrade only if you’ve SHSH saved via Cydia

Dogge March 22, 2010, 7:05 pm

Many thanks. Well its only to smile and let the future se what happens then. I have no files saved.
Life goes on.

Thanks again for your answer.

zozazen March 22, 2010, 7:53 pm

Stuck ….. Updated the iPhone 3G to 3.1.3, I am on unofficial carrier. Now It’s locked. I want to jailbreak and unlock it . I use Windows. Can you guys help me with a solution?

iPhoneHeat March 23, 2010, 1:22 am

use the custom firmware or RedSn0w to jailbreak…
You cannot unlock baseband 05.12.01.. sorry

EdVonage March 26, 2010, 1:15 am

I have a 3GS with the older 05.11.07 firmware jailbroken with 3.1.2.

With the above setup should I **NOT** use the custom 3.1.3 IPSW or is it OK?

iPhoneHeat March 26, 2010, 4:39 pm

You can but I strongly recommend you to stay away from it 🙂
you have the best software on ur device.. 3.1.3 is just a minor fix
Avoid it!

EdVonage April 16, 2010, 7:34 pm

Thank you. Other then the fact (and I agree) that it isn’t a necessary upgrade to 3.1.3, IF I do decide to do this, can it then be unlocked using Blacksn0w ?

Is your recommendation to “stay away from it” for any specific reason other then that it isn’t necessary?

Thanks for your effort and your support!

iPhoneHeat April 16, 2010, 9:37 pm

you can unlock.. if you upgrade via custom firmware preserving ur baseband..

freepass April 2, 2010, 11:27 am

I followed the above guide for my 3GS with 05.11.07 using Activated firmware.Everything went well except that I don’t get a signal at all.I installed Ultrasn0w and still no luck.
What seems to be the problem?
Appreciate your help in advance.

iPhoneHeat April 2, 2010, 3:04 pm

install BlackSn0w RC2 final.. checkout the unlock iPhone category

freepass April 2, 2010, 9:06 pm

I did that right after I realized that Ultrasnow isn’t working.I begun having more problem that was,I assumed, due to the conflict of 2 unlock programs.I tried each unlock separately.The Ultrasnow doesn’t freeze my iphone as the BlackSn0w RC2 final does.So here I am with Ultrasnow and not working network:(
Any other thoughts please?:(

My phone (3G) is now using Jailbroken 3.1.2(7D11) with baseband 02.26.08. If I install 3.1.3, will it update my baseband?

iPhoneHeat April 6, 2010, 9:34 pm

Custom firmware do NOT upgrade your baseband 🙂

Hello! I would be glad if you can help me. I have a jailbroken and unlocked iphone 3GS. The current OS is 3.0.1, Model MC, Modem Firmware 04.26.08. Can I safely upgrade to OS 3.1.3, jailbreak and unlock it using this method? I am new to this. Thanks a lot.

iPhoneHeat April 7, 2010, 4:22 am

Yes you can using the custom firmware but I do NOT recommend you to do so atm..

magiclove April 8, 2010, 1:19 am

Hi, I am very new with Iphone. I recently bought an iphone 3gs version 3.1.3(7E18) Mode MC135LL and modem Firmware is 05.12.01. The guy sold me this phone told me that it can be used with AT&T sim card. I don’t know it my phone can be unlock???

iPhoneHeat April 8, 2010, 2:39 am

yes you can use it with AT&T only..
Unlock for the latest baseband that comes with OS 3.1.3 is not out yet..

XMaRkstheSpOt April 10, 2010, 11:19 pm

HI, Was wondering if ANYONE would know when and if that timeline for UNLOCK (3.1.3) , would be available? PLZ…..

Thanks 4 ur file.
That works for my iphone 3G 3.1.3 with baseband 5.12.01, Model MB, Bootloader 5.9.
I’d sync with itunes and updated everything, lost my cydia and all my jailbroken apps, couldn’t downgrade to run blackra1n, couldn’t apply my custom sn0wbreeze firmware.

1. iReb to get my white screen
2. install ur custom firmware for iphone 3g 3.1.3 not activated ****** (I use my iphone with the vendor so dont need to unlock it.)

Thanks for your file.


Godwin April 13, 2010, 10:34 am

Hi Bro i’m from india, i’m new to iphone
I bought an iphone 3gs from my friend on march 2010 which was already working with a local
carrier but my friend had a password lock, without asking my friend for password i entered wrongly
and got stuck with it and i was forced to update and now i’m not able to access even my sim card i
soon found that i made a big mistake by updating my firm (even my friend who sold has no idea
About phones)
From that day on i watched many videos how to hack, jailbreak, unlock & activate but nothing
i don’t know what firmware it had, serial no, baseband or i’m not even able to find out whether it is a
mc or non mc model
but today I did one thing (Patched firm 3.1.2 with redsnow and installed) which enabled me to find
the serial no, capacity and the software version installed but still i get the iTunes symbol with a usb
plug pointing above and the emergency call screen


Model No: A1303 (16 Gb Black)
Serial No : 879270HE3NP
Software version 3.1.3
Capacity 14.28 GB

I found that you are the most genius person who will definitely be able to make my phone come
Alive HelP!!!!! Me please!!!!! 🙁
i’m having this mobile unused for about a month Help me!!!!
Please reply if you have any idea or even have no idea.
I’ll can even pay you 10 bucks for you to unlock

u can’t unlock if you directly updated to 3.1.3 without using a custom firmware

magiclove April 16, 2010, 11:44 am

I got the same proglem just like your, I could not unlock it now, but I am able to recovery back to original by simblly put an AT&T sim card into iphone and let itune reset the phone to original.

sowat99 April 14, 2010, 5:18 pm

I would just like to ask about my iphone situation.
My iphone is NOT jailbroken and is a 16GB 3GS, 3.1.3(7E18), and Model: MC132B(i believe this has the updated bootrom) my iPhone is OFFICIALLY unlocked by apple. My question is, if I want to Jailbreak my iphone, will I lose my OFFICIAL UNLOCK STATUS? I want to be Jailbroken without losing my legit unlock. Please reply thanks.

EdVonage April 17, 2010, 12:09 am

I am on AT&T but I also want to use foreign SIMs while traveling. Should I be downloading the ACTIVATED or UNACTIVATED custom firmware?

I just download the ACTIVATED version but I no longer get an AT&T signal … I get nothing. If I install the UNACTIVATED version will I be able to unlock it after activating?

Cgnar513 April 20, 2010, 8:07 am

I’m having problems here..,

Help me in this..
its giving me a headache…

iPhoneHeat May 1, 2010, 1:12 pm

use iReb to get rid of this error.. search the blog for iREB

pradeep May 7, 2010, 1:35 pm

This custom firmware i can directly install on my iphone using shit+restor??? is it base 05.11.07?? because i have to use unlock.

iPhoneHeat May 7, 2010, 2:34 pm

CFW preserves wotever baseband you have..
your device specs?

pradeep May 7, 2010, 4:44 pm

I am having Iphone 3gs 32 GB – 3.1.2 – 05.11.07-Serial number – 859428B83NR. I was using Blackra1n for jailbreak and then black snow for unlock. But i made the mistake of using Spirit on my phone. So now it doesn’t boot. I tried to restore to 3.1.2 using this custom firmware.

But it didn’t work. Even though i tried setting up the local restore verification server.

I had created the SHSH files yesterday morning only, so i am not also sure abt whether they are correct.
So i just want to restore my iphone 3gs to 3.1.2 or 3.1.3 with modem as 05.11.07 so i can use blackra1n or spirit for jailbreak and blacksn0w for unlock.

iPhoneHeat May 7, 2010, 10:02 pm

there’ll be guide for restoring old firmware with shsh soon..
for the time being please google for a guide

shruti chadha May 8, 2010, 2:42 am

iPhoneHeat May 8, 2010, 2:31 pm

without SHSH you cannot restore 3.1.2 on 3GS..
3.1.3 is only option for you.. sorry

custom firmware not work

muffo May 12, 2010, 6:27 pm

Hello ive been having this problem for a while. I have a 3g iphone that i reset to factory default now its asking me for the origional sim that i dont have sooo, ive been messing round for ages trying to find a solution so here goes.

I have windows 7 downloaded this and used that hj split which turned it to a .zip file ( and 2 others with same result=nothing) i need a .ispw file 🙁 why dos this keep happening to me. btw this 104mb .zip would not run in winzip i also tryed to rename it but that failed in itunes PLZZ help

muffo May 12, 2010, 6:29 pm

cant i just download this .ispw file AS an .ispw and just USE it with itunes from somewhere plz help

iPhoneHeat May 13, 2010, 4:59 am

Use spirit jailbreak (chkout the jailbreak iPhone category)

acutex May 14, 2010, 11:55 am

i currently 3GS 3.1.2(currently jailbroken and unlocked), 05.11.07. i Want to update to 3.1.3 with CFW so i can jb with spirit and then unlock with blacksn0w. will this be possible? i already have my shsh installed locally using umbrella and tinyss as my tss server

iPhoneHeat May 14, 2010, 3:07 pm

you can’t use Spirit jailbreak.. coz on already jailbroken device, Spirit conflicts and iPhone stuck at boot screen.

You better stay with 3.1.2.. there’s nothing new in 3.1.3

Acutex May 14, 2010, 6:44 pm

I want untethered iPhone and only spiritjb can offer that. What I want to know is if I can update my firmware with CFW 3.1.3 will still be able to unlock with blackrain rc2

iPhoneHeat May 15, 2010, 2:07 am

if it’s 3GS, then you better avoid it.. it’s risky

kodeina May 16, 2010, 8:43 pm

I have a 3gs with 3.1.3, unknown baseband but newer bootromn. my phone now’s stucked on emergency calls, so is not activated. Since my main problem is that i dont have imei/baseband/iccid/wifi/etc i was wondering if your cfw will work on new bootrom just to activate my phone, so i can use it as an ipod for the moment. thank you.

iPhoneHeat May 16, 2010, 11:36 pm

Only solution for new bootrom at 3.1.3 is Spirit jailbreak and it requires you to have access to the Home screen..

kodeina May 17, 2010, 12:53 am

Thank you for your answer. I have managed to downgrade it to 3.1.2 even 3.1.0 and jailbreaked, but with no luck. I have the no emai/baseband/wifi/bluetooth problem, someone told me the baseband is corrupt but still no luck. Thank you.

mefistox May 18, 2010, 12:56 am

I have 3gs 3.1.3, an MB model with 05.12.01 modem firmware. Will this method work for me to jailbreak and unlock the iphone?

Hi, first of all I would like to say thanks in advance if you help me out. I have an

iPhone 3gs:

Could I get this device with an UNTETHERED JAILBREAK & UNLOCK?

iPhoneHeat May 18, 2010, 10:50 pm

is it already jailbroken?

rokius May 19, 2010, 11:42 pm

it is jailbroken/unlocked with blackra1n, but it is only a tethered jailbreak right now.

Anapmtorres May 26, 2010, 5:13 am

Hi, I have a 3Gs 3.1.2 baseband 5.11.7 Unlock and jailbroked it was working fine until last friday when I up date my iTunes. Now my phone doesn’t work I tried everthink but I don’t restore to 3.1.3 yet.

I was almost instaling the oficial 3.1.3 and will wait for the unlock but now that I found your custom firmware I hope it will solve my problem.

If I install your custom firmware I’ll have an iPhone unlocke and joailbroke?

Thank you for your help.

iPhoneHeat May 26, 2010, 10:46 pm

what’s the problem with ur phone now?
CFW for 3GS sometimes doesn’t work and give you errors while restoring and there’s no iREB support to fix those errors

anapmtorres May 27, 2010, 5:24 am

When I try to jailbreak using Blackra1n the GeoHot picture apears and after a long time it reboots and starts again. It goes while the phone is conected to PC and the Blackra1n is open.

de0s May 28, 2010, 9:09 am

I have an iPhone 3GS, fw 3.1.3, bb 05.12.01 and new bootloader. I am stuck at the emergency screen because I don’t have the official carrier to activate. I know there is no unlock for bb 05.12.01 so for the moment I only want to be able to use my iDevice as an iPod. For this I thought I could use a custom fw already activated. But I have few questions about the process:
1. Will I be able to write a custom fw to my iPhone considering I have the new bootloader?
2. After I write the activated custom fw, when iPhone will boot and after that will show the springboard? (skipping the activation screen)?
3. If the answers for 1 and 2 is yes, which cfw should I use?

Thanks a lot in advance

iPhoneHeat May 30, 2010, 3:22 pm

CFW 3.1.3 for 3GS – Activated

richietnt May 29, 2010, 4:25 am

hello all,
if i use 3.1.3 “NOT Activated (for Official Carrier Users)” on my iphone 3g with my O2 Sim so that it is activated, will i be able to unlock it to another network, and if so what app do i use?

iPhoneHeat May 30, 2010, 3:29 pm

unlock depends on ur baseband..
05.12.01 is not unlockable atm.. but 05.11.07 can be unlocked with blacksn0w

richietnt May 30, 2010, 4:37 pm

my baseband is 05.11.07 as i have been able to downgrade, what’s strange is that,voice mail icon comes up but the carrier and the signal indicator are all just little dots.
i have tried both.
iPhone 3G Custom Firmware 3.1.3 IPSW
Activated and NOT Activated…..same result


Aamirmaq June 2, 2010, 6:52 pm

Mine is 3gs 3.1.2 5.11.07, I lost wifi, service, IMEI, Bluetooth one day, I reset network settings but in vain then I reset all contents and settings. From that time onward Iphone is stuck in 10 minutes cycle of apple logo coming and going. Tried to restore it to 3.1.2 but Apple says “the device is not eligible for the requested build” Plz advice should I try to update it to CFW 3.1.3 and will I be able to unlock it? Forecast doest not give any information on Firmware etc

iPhoneHeat June 2, 2010, 10:20 pm

checkout the iPhone guides section.. there’s a guide on how to fix recovery boot logo..
and make sure you save SHSH blobs for OS 3.1.3 using firmware umbrella..

wakas June 3, 2010, 11:42 pm

Hi. i have 3gs 3.1.2 with 5.11.07 baseband. Its jailbroken with blackrain and is tethered. i want to ask can i use 3.1.3 CFW to jailbreak it and then then unlock it via blackrain RC2. So that i can have an untethered jailbreak.

iPhoneHeat June 4, 2010, 2:50 pm

Spirit is the only untethered solution for you (OS 3.1.3, 3.1.2).. but the down side is, Spirit do not play well with Blackra1n jailbroken devices so avoid it..
on the other hand CFW sometimes gives error during restore and there’s no iREB support for 3GS to fix those errors.

So, best thing for you is to save SHSH blobs for OS 3.1.3 using Firmware Umbrella and wait for the baseband 05.12.01 unlock to come out.. then go for OS 3.1.3 🙂

rickystraky June 10, 2010, 3:01 am

i have an iphone 2g which i jailbreak/unlocked and it says no service when i put the sim card on it. it never finds signal. this happened after i tried to unlock it. could you help me please. i would appreciate.

Hi..i have a 3GS on firmware 3.1.3 05.12.01 jailbroken with SPIRIT and unlocked with sn0wbreeze..all worked well until I decided to put it in its factory settings (stupid me) now it’s stuck in DFU mode and everytime I connect to iTunes it says I should restore and upgrade to OS4 (I didn’t approve this). Is there any way I can restore my iPhone to 3.1.3? Help me please…thanks

iPhoneHeat July 16, 2010, 4:48 pm

use RecBoot or tinyUmbrella to fix recovery loop

Joviano July 16, 2010, 8:01 pm

Are you sure about this iPhoneHeat? Is it just THAT simple using RecBoot or tinyUmbrella to fix my iPhone? Not to question 🙂 but I’m just worried if it will worsen/brick my iPhone. Thx for the reply.

iPhoneHeat July 16, 2010, 8:35 pm

it’s safe..
you always have the option to restore official firmware or the one for which you have saved SHSH blobs

Joviano July 17, 2010, 9:12 am

Ok man, I’m sooo tired of googling and trying so many stuff on my iPhone and nothing worked. What if I do the steps above (restoring via iTunes using the 3.1.3 CFW mentioned in the article above)? Will it worked? I already tried it and got ‘1604 error code’. I just clicked ‘OK’ and nothing happened. Please help me..kinda desperate here 🙁

Joviano July 17, 2010, 11:02 am

FYI, my iPhone 3GS 16GB specs: 05.12.01, 3.1.3

Here’s my steps of getting this far:
1.Created my 3.1.3 ECID.shsh file using AutoSHSH
2.Jailbroken it using SPIRIT
3.Unlocked it with sn0wbreeze 0.92
4.Erase All Content and Settings (which made my iPhone stuck in DFU/recovery mode)

Is there anyway I can put it back to 3.1.3 factory settings?

IF I follow iTunes and restore it also upgrading its software to iOS4, will the jailbreak and unlocking tools be soon released?

Thanks for the info.

iPhoneHeat July 18, 2010, 1:47 am

SHSH saved for 3.1.3?

Joviano July 18, 2010, 9:49 am

Yes, I guess..? Is the saved file supposed to be in (dot)shsh? Or was it supposed to be saved in Cydia or something? I tried your 3.1.3 Activated CFW, but I got an 1604 error code. What’s my options?

Joviano July 20, 2010, 5:40 am

Hey man, please reply ASAP! I’m waiting!

iPhoneHeat July 20, 2010, 11:59 pm

here’s how to download older SHSH if saved via Cydia and then downgrade firmware

Joviano July 21, 2010, 3:19 pm

Mine’s already updated to 4.0.1 via iTunes. Does that still count as ‘downgradable’ to 3.1.3..? 🙁

iPhoneHeat July 22, 2010, 5:12 pm

Yes, if you’ve SHSH saved.. follow the link posted in my previous response

I have an iPhone 2g running firmware 3.0 for quite some time now. I have upgraded many times and used quickpwn and redsnow many times to unlock my iPhone.

I have a major problem and was hoping you might have an answer. I need to upgrade to 3.1.3 as I am having issues with my iPhone not connecting to itunes. My sleep/wake button is broken and I can’t seem to get it fixed.

Is there a way to upgrade to 3.1.3 without using the power button?

kapdaryl15 August 19, 2010, 11:22 am

hey guys… want to ask….. how do you removed the .001 in the ipsw after the .zip file name…. coz it always make the file damage or currupt… please help me…

iPodalot September 12, 2010, 2:17 am

You could try a few things

Try deleting the .001 after the .zip and then unzip the file.

If it doesn’t work, .001 usually means a split file or an archive, so try unzipping with winrar or hjsplit.

SoFedUP! September 24, 2010, 3:22 am

hello. i hav a 3g, i’m not using n official carrier but accidently updated to 4.1 now the only thing that shows up on my screen is the itunes and usb logo, i wnna kno if i can place my phone in recovery mode then restore to a lesser firmware file? and if so wat are the steps

iPhoneHeat September 24, 2010, 4:10 am

connect to iTunes.. Put iPhone into DFU mode.. restore OS 3.1.3

Dani October 18, 2010, 8:51 pm

Hi there,

I’m looking to upgrade from OS3.0 to OS3.1.3. My iPhone 3G is currently jailbroken and unlocked.

If this tutorial will help me install OS3.1.3 already jailbroken, do I still need to re-unlock it with Ultrasn0w ?

I’m asking because all Ultrasn0w tutorials I’ve seen revolve around installing Ultrasn0w in Cydia and then rebooting the phone…but I’ve already done this with 3.0…

Thanks a lor to clarify.

shamss November 4, 2010, 1:04 am

Hi, I have the 3gs with the 4.1 firmware , tried all sorts to downgrade to any other firmware but didnt work, downloaded tiny imbrella ive got the shsh, tried ireb when ive had 1600 error aswell didnt work the same thing with the error 1015 fixer. really guys i need help. the biggest mistake ive made by updating to 4.1 🙁 🙁

RaptorX November 11, 2010, 9:49 am

The links are totally broken. First off, it took me about an hour and a half waiting to get all 3 parts of the download. Secondly, WinRAR isn’t recognizing the .001, .002, or .003 endings. I tried changing the name to just .zip, but the files were said to be corrupted. please help by putting them up on some other website or something.

profire November 16, 2010, 2:46 pm

use a software called HJsplit – open – join – input – select file with .001 extension. it will do the rest if other files
(002 and 003) are in the same directory. then use winrar to extract the newly joint file

perissis November 12, 2010, 5:52 am

Which option should i choose? ACTIVATED? or NOT ACTIVATED?

i installed the new release of iREB and it worked well and my iphone 3g 3.1.3 turned green in color according to description.
When i try restoring custom firmware (3.1.3) via itunes it gets stuck in the process of restoring firwmware and my iphone screen gets a logo of itunes and cable means its in the restore mode then error pops up “1603”. It shouldnt have poped up as i already used iREB.
Please help its more than 12 hours for me to get stuck on this thing.. :((

nick January 18, 2011, 9:01 pm

listen mate
the 1600 error will go away open itunes turn ur phone off
press home + sleep key for 10 sec then leave sleep key and keep holding the home key
then itunes will ask u phone in recovery mode

then open ur taskmanager and kill the ipodservice
if that will be running i will never be able to restore

just to let the readers know i was able to successfully download the IPhone 3G Custom Firmware 3.1.3 IPSW Activated (for UnOfficial Carrier Users) – join it with StuffIt Expander for Mac. Then use iTunes to restore on my iPhone 3g. I was earlier running iOS 4.2.1 using baseband 6.15 and iPhone became slow. Restoring 3.1.3 back made it a little faster.

hi everyone – I have a iPhone 2g, 1.1.4, 04.04.05 baseband jb’d with iliberty (downgraded/restored from 3.1.3, 5.11.04 bb, to get my WIFI back)
I got my wifi back! BUT, I’m afraid to upgrade back to 3.1.3 – I don’t want to lose baseband and wifi again.
How can I upgrade to 3.1.2 or 3.1.3 and keep my baseband?
Any help? I’m a noob by far but can follow instructions (no experience with verbose, only programs, please)
Thanks for any help!

UUgh – I boot nuetered FB at 3.9, then tried to go back to 3.1.3 – it worked! But, now I have jb/ul 3.1.3 at 04.05.04 modem again! (Sorry I don’t know why it says 5.11.04bb on my last post – I had 04.05.04 and 3.1.2 to begin with).

All that trouble, when I lost WIFI after updating my iphone 2g 3.1.2 to 3.1.3 in iTunes,I lost my wifi and after much trial and error was able to downgrade to 1.1.4 and 4.04.05 bb )iliberty + “Xiphone” method) and my wifi was working fine! But, no mms, vid camera, etc – so I wanted 3.1.3 back, got it back on FB’d 3.6 bootloader – jb’d with redsn0w 9.4 on 3.1.2 fw – now have jailbroken/unlocked 3.1.3 with 4.05.04 again – BUT NO WIFI. I’m so pissed.

sorry, did it again, I mean its FB’d at 3.9 bootloader (not 3.6)
Any ideas on how to get the 4.04.05 (working wifi modem fw) to stay with 3.1.2/3 on iPhone 2g (originalmodel A1203).
Thanks for any help!
