In this Guide you’ll learn how to downgrade iOS 4 firmware to OS 3.1.3 / 3.1.2 or older firmware with TinyUmbrella. This downgrade guide applies to all iPhone and iPod Touches. To downgrade iOS 4 to OS3.1.3 / 3.1.2, there’s no need to edit any Hosts file that is required in other guides found all over the cloud. We are going to setup downgrade server the TinyUmbrella way: with a single click.
IMPORTANT
iPhone 3GS, iPod Touch 3G and iPod Touch 2G (MC) users MUST have SHSH blobs saved for 3.1.3/3.1.2/older firmware in order to downgrade.
How to: Save SHSH blobs for iPhone, iPod Touch and iPad
If you’ve SHSH blobs saved on Saurik servers via Cydia, you need to download them into your computer. To do that:
- Connect your device, Fire up the TinyUmbrella (Download Link below-Step 1) and Check mark the Advanced Options.
- Select your device, firmware (the one for which you’ve SHSH saved at Cydia; 3.1.3 or older) and Cydia as Location.
- Hit the save My SHSH button. that’s it. (check: Where it saves SHSH)
(e.g: to download 3.1.3 shsh blobs from Cydia see the screenshot below)
NOTE: If iPhone 3GS, iPod Touch 3G and iPod Touch 2G (MC) users do NOT have SHSH blobs saved for an older firmware, they can NOT downgrade.
Downgrade iOS 4 to OS 3.1.3/3.1.2 firmware
*** Read the whole process first and then try.***
Step 1 – Required Stuff
Download TinyUmbrella and firmware 3.1.3 or 3.1.2 for iPhone 3GS, 3G, iPod Touch 3G, 2G from the links below:
Step 2 – DFU Mode
Put your iPhone into DFU Mode (How to: enter DFU Mode)
Step 3 – Start TSS Server
iPhone 3G and iPod Touch 2G (Non-MC) please skip to step 4. iPhone 3GS and iPod Touch 3G and iPod Touch 2G (MC) users:
- Run the TinyUmbrella
- Hit the Display SHSH button to confirm that downloaded SHSH blobs has been cached by TinyUmbrella for 3.1.3 or 3.1.2. (If you already have them in your PC, drag and drop the SHSH blobs in the TinyUmbrella window then hit the display SHSH blobs button to confirm). See the screenshot below.
- Then hit the Start TSS Server button
Step 4 – Restoring the Firmware
- Now Open the iTunes.
- Hold down the Shift (Windows)/Alt (Mac) key and hit the Restore button.
- Select the downloaded firmware (from Step 1) and let the restore process complete.
iTunes will bring up error 1015, 1013 or 1011 message. Don’t worry, it’s normal. You’ve successfully downgraded your iPhone/iPod Touch firmware.
Step 5 – Getting Out of Recovery
Now in order to get out of recovery mode, hit the “Kick Device Out of Recovery” button on TinyUmbrella right below the Start TSS Server button. That’s it!
Now you can jailbreak iPhone OS 3.1.3 with Spirit, PwnageTool, Sn0wBreeze, RedSn0w and custom 3.1.3. To jailbreak iPhone OS 3.1.2 you can use RedSn0w, Sn0wBreeze, BlackRa1n, PwnageTool and custom 3.1.2.
You can always unlock iOS 4, 3.1.2, 3.1.3 on baseband 05.12.01, Baseband 05.13.04 and 05.11.07 using UltraSn0w 0.93.

Thanks!
Read the Important part in the guide..
Your selection under advanced options should be:
Your ECID
iPhone 3GS 3.1.3
Cydia
I’m back in business WAHOO ! LMAON
I’m running 4.0 jail broke without using snowbreeze,I used spirit2 in cydia and pwnage tool simple mode and WALA LOL
I have an iPhone 3G
after I restore to 3.1.3 how do I get out of recovery mode??
Use the Kick out of recovery mode button using TinyUmbrella
I did, but the phone didn’t restart like it should.
Still showing the connect to iTunes.
Same here. I clicked “Kick Device out of Recovery” and it’s still showing the connect to iTunes screen.
TinyUmbrella Links are updated now.. Older version has this problem..
Sorry for the inconvenience.
iTunes keeps telling me that I need to restore so that I can use my phone…
close all the programs and try the whole process again.also try to use different usb port
i updated my 3gs 4.0 w/new firmware 05.13.04 how can in jailbreak my phone
this does work. downgraded from 4.0 to 3.1.3 and then jailbroke with Spirit and unlocked with Ultrasn0w
*note the baseband does stay at 05.13.04 and does not downgrade to previous 05.11.07 or 05.12.01
Thanks for the input 🙂
*if you have pictures on your phone, transfer them onto your computer before you proceed as any backups made with iOS 4.0 will be useless on 3.1.2 or 3.1.3*
Listen up everyone.
Here are the steps I used
1. turn off iphone
2. place iphone into DFU mode (hold sleep and home for 10 seconds, then release sleep and hold home for another 10 seconds)
3. plug iphone into usb and open TinyUmbrella
4. grab SHSH blobs for 3.1.2 or 3.1.3 from Cydia if you have not done so already
5. click on Run TSS Server (you’ll need admin privelidges on Windows Vista/Windows 7)
6. open itunes, you’ll get a message telling you the phone is in recovery mode. click ok, and then Shift-Restore and select the IPSW that you will downgrade to.
7. itunes will then begin the restore and eventually error out with 1015. don’t worry, the restore is complete, just the phone is stuck in recovery mode and needs to be kicked out
8. go back to TinyUmbrella and stop the TSS Server
9. click on Kick Out of Recovery Mode
i had some difficulty kicking my phone out of recovery on Windows 7 (the button was grey’d out for whatever reason), i started up XP mode and was able to finish the job.
how did you do that?
What tinyumbrella did u have to download? the latest one has a mirror 1 or 2.
I downloaded TinyUmbrella 4.0.0.54 and then clicked “Kick Device out of Recovery Mode” and it worked fine. 4.0.0.49 doesn’t work right.
TinyUmbrella Links were not up-to-date when the guide was published.. Sorry.
Links Updated!

My shsh blobs are saved in cydia but i dont have them saved on my pc…can i still downgrade? 3.1.3 32 gb ipodtouch 3g
Did you read the post?
so now my phone is 3gs 4.0 new firmware is there a jasilbreak out yet
i didnt save blobs
You can’t, atleast for now..
wait for the Spirit Jailbreak update that is expected soon
I can’t seem to get the server to run. It says in the window that I need admin. priviledges. But, I do have them on my laptop.
I’ve never run into this before (needing admin P’s)
any thoughts??
Tom
this is what I followed >http://www.saurik.com/id/12#howto
It’s because Port 80 is in use.. Read the details in the box below it also tells the same thing..
see which application is using Port 80 and close it..
or log into another user and run as admin
WOW…what,do you sleep at the computer?? :)) That was a fast response!
Ok, will check port 80 and thanks to the other response, too
Further…
I have a 3GS on iOS 4.0. The program recognized my phone just fine and gathered the 3.1.2 blobs from Cydia with no issues. It’s just the sever that won’t start.
I think you have to run it as administrator
Got the shsh from cydia for 3GS 3.1.3 without a problem only to end up with error 3014 during the verification of the restore.
TinyUmbrella logs: log.txt
Never mind, i just edited the host file and downgrade to 3.1.3 but now i am stuck with redsnow at “waiting for reboot”. Any one know some trick to get around this problem?
Simply Keep retrying

Cheers

i have an iphone 3gs and the process was working.. I received error message (1015) also but my Kick Out of Recovery Button will not highlight…. What should I do :(!

or please call me 9962273597
is there a way to downgrade from 4.0 to 3.1.3 without saving shsh blobs ??? i uppgraded my iphone 3gs 3.1.3 to 4.0 and now i cant jailbreak it.
No.
i am getting an error in umbrella it wont install
Make sure your have Java runtime environment installed
i have a 3GS that’s already on iOS 4.0, is it possible to downgrade without the SHSH blobs (i’ve tried checking for the 3.1.2 blobs with TinyUmbrella but there was none)? i know that right now, the 3GS that’s already updated to iOS 4.0 can’t be jailbroken yet.
can’t downgrade without SHSH
when i bring up tinyumbrella it says cached 0 shsh files, then i clicked display shsh’s and it says ECID’s can be restored to the device safely or whatever… how do i know if the shsh’s were saved or not on my iPhone 3g?
iPhone 3G does NOT required SHSH blobs to downgrade 🙂 did you read what that step says?
I just tryed it 3 different times and it didnt work.had to resotore my 3g 3 differnt times with the 4.0 software… you hit the kick out of recovery mode button and it does nothing at all.
any error?
Yea after the error 1015 comes up, I hit the kick out of recovery mode and nothing happened…. Then itunes just continues to say they’ve detected an iPhone in recovery mode… And the only way to get it out is to restore with the 4.0… Any suggestions??
im running on windows 7 does that have anything to do with it?
what am I doing wrong??
for iPhone 3G
Download OS 3.1.3
Put iPhone into DFU mode
open iTunes. Hold down shift key and hit restore
browse and select the os 3.1.3 or 3.1.2
and it should work fine without an error for iPhone 3G..
in my case i didn’t even put iPhone 3G into DFU mode and it downgraded in first attempt
I followed the entire procedure and at the end it gave me error 14. Now i cannot escape from recovery mode. Does it has something to do with the version of itunes I am using? I’m on 9.2 version. Do I need to install 9.1 version?
use the kick out of recovery button on TinyUmbrella
I have finally downgraded my iphone 3gs into 3.1.3 previously upgraded to ios4.0. Good thing I have saved my shsh blobs through cydia before upgrading to ios 4.0.Here’s what I did, I hope it can help all of you:
1. Download tinyumbrella (4.00.54)
2. Download ios 3.1.3 from this thread (make sure that you downloaded the necessary firmware to match your device). I suggest to save it on your desktop so you can find it easily.
3. Plug your iphone into usb port.
4. Run tinyumbrella (right click, properties, run with xp compatibility, run as administrator).It will detect your iphone with ios4.0. Click advance option, find iphone 3gs (7E18)then don’t replace cydia on the window, then save shsh. It will prompt that 3.1.3 firmware is available. To confirm, click display shsh.
5. Now, turn off iphone
6. place iphone into DFU mode (hold sleep and home for 10 seconds, then release sleep and hold home for another 10 seconds)
7. plug iphone into usb and open TinyUmbrella (in xp compatibility mode)
8. click on Run TSS Server (let it run, do not interrupt)
9. open itunes, you’ll get a message telling you the phone is in recovery mode. click ok, and then Shift-Restore and select the IPSW that you downloaded.
10. itunes will then begin the restore and eventually error out with 1015. Just ignore it. Your phone is now in recovery mode.
11. go back to TinyUmbrella and stop the TSS Server
12. click on Kick Out of Recovery Mode. if your having problem going out of recovery mode, try to transfer it to another usb port, then repeat the process. If it still the same, try to manage another account on your computer and repeat the same process in there. More or less these are the things I have done, well I know it’s a long process, but at least there is hope and I found it very exciting to wait for the outcome. By the way I’m using Vista. I don’t know about other OS. Good luck everyone! Thanks iphoneheat!
The 3.1.3 I get is for MAC, I believe, as when I unzip it it does NOT remain a valid IPSW file; instead I get more than one files including DMG ones, which are for MAC.
I have Win 7 64-Bit.
why one would extract IPSW?
Thanks for your promt reply.
The link to the 3.1.3 used to give me a zipped file. Anyway, I found a valid ipsw file from another link and restored my 3Gs to 3.1.3.
Now when I want to restore through iTunes t the custom IPSW 3.1.3 that I made thrugh Snowbreeze, I get the 1600 and sometime the 1604 error.
May be it is because of the 9.2 iTune version, so I am going to install an older verison of iTune and try the restore. Thanks for your time!
http://www.iphoneheat.com/2010/02/fix-16xx-and-29-error-during-custom-firmware-restore/
I just did this on OS X and it worked great! Thanks!
Downloaded older iTunes and was able to jailbreak with Spirit. Nice guide; thanks!
Alright guys I got it… downgrade successful but the only thing is I lost everything on my phone, I mean EVERYTHING contacts, pics, etc… what am I gonna do!! I wonder if my old backup will be on itunes if I upgrade back to 4.0??
if you let iTunes backup the last time you connected your iPhone then simply restore that backup
The ipod touch 3.1.3 or 3.1.2 dont work what sort of bs is that, none of the links work. Now i have completely cocked up my ipod thanks a bunch
I tried saving the shsh with the 3.1.3 firmware and umbrella is coming back saying that the device isnt eligible for the requested build..?
means you had not saved it via Cydia when it was being sign by Apple. Correct?
I get error 28 when i follow your tutorial 🙁
My ipod come with 3.1.3, and now in OS 4 ..
I want downgrade,

hey. i followed all the steps but i didnt get the error 1015, 1013 or 1011 message. what happened was, i was able to restore my ipod touch 2g(mc model) to 3.1.2 instead of getting the error, when i restored it, i got this, “verifying ipod restore with itunes”. i waited for 30mins and there was no response. May i know what went wrong?

Guys i have a problem i am not very good at this so i have a question i have an ipod 3g mc model. i don’t understand where to get the “SHSH blobs” for 3.1.3 cuz i have the 4.0 firmware already installed. So…… if you have a bit of time can you help me?

This is utter garbage, I don’t understand why others are able to do this but IM still getting the same error code 3014. so i guess its just not working for me. tried a good number of times now.
HELLLLPPPPPPP!!!!
Make sure TinyUmbrella has cached SHSH blobs for the firmware you’re downgrading to.. (Click Display my SHSH to confirm)
I have followed all the steps but still not working………. what is this Error code 3014. I’ve tried a number of things to get this work.
Are you on Mac?
The developer himself confirms that Mac users are encountering this error.. Hopefully it’ll be fixed in future update

Unlock it possible but your iPhone must be jailbroken.. which is NOT possible for 3GS @ 4.0.. Wait for a few days for Spirit jailbreak update

Hey Mr. iPhone heat, do you have any answer as to why we get error message when we downgrade our ipod touch 2g (MB model) from OS 4.0 to OS 3.1.2/3.1.3 ?
I tried all the possible ways,i.e. changing host file, using DFU mode and using that tinyumbrella thing.
FYI I haven’t jailbroken my ipod touch and dont want to. I just want 3.1.3/3.1.2 firmware on my ipod. THATS IT.

Hey, I’m trying to restore my 3G, but I’m stranding at step 4.
I’ve saved my SHSH blobs, but when I’m asked to select the firmware, I can’t install it because it’s saved on my pc as a .shsh file, and itunes is looking for an .ipsw file.
Where am I going wrong?
Sorry, being stupid, problem solved. 😉
Shouldn’t do these things when it’s late.
Hi, i have an ipod touch 2g (MB model). I upgraded my iOS to 4.0 and noticed that it’s REALLY SLOW. So I decided to downgrade it back to 3.1.3. I downloaded a copy of 3.1.3.ipsw, edited the hosts file, placed my unit in DFU mode, but I’m still getting error 3194.
I got really frustrated and downgraded it to 3.0, somehow it worked but my apps don’t work in 3.0 and now I want to upgrade it to 3.1.3, still getting error 3194.
Can somebody help me please?

THanks in advance, and great guide 🙂
me too… help!
all of you getting problems with ipod touch 2g mb model 3194 error you need your shshs to downgrade
first you need to change your hosts file and add 74.208.105.171 gs.apple.com
to your hosts file in C:\Windows\System32\drivers\etc\
edit it and add it under ::1 localhost
then start tss server and restore
I did everything as I was supposed to, but it won’t work. The iphone simply goes to a white screen and itunes hangs on “Preparing iPhone for restore…”
Trying to roll back my iPod Touch 3 with OS4 to OS3….
I click Save My SHSH and get this: CYDIA DOES NOT HAVE YOUR SHSH FOR iPod3G 3.1.1 (7C145) THERE IS NO WAY FOR YOU TO GET THEM. SORRY. YOU ARE JUST TOO LATE.
“This device isn’t eligible for the requested build. ”
What does this mean and How do I fix it?
hi, i did not save SHSH blobs for 3.1.2 before. my iphone is running now 4.1 ,which is not jailbroken, i m trying to save SHSH blobs for 3.1.2 but i thing it is not possible now i m saving SHSH blobs for 4.1. So is there any other way to downgrade 4.1 to 3.1.2 or is there any other way to jailbreak 4.1 whiyout reguaring to downgrade 3.1.2. My iphone is 3Gs (newbootrom).
Why does iPhoneHeat neglect the iPod Touch 2G MB users? There are quite a few asking for help, and iPhoneHeat has not replied to any one of them. If SHSH blobs are required to downgrade the MB model, then this guide should be updated. Has anyone with said device been able to downgrade successfully?
iTouch 2G MB and iPhone 3G users can downgrade to 3.1.x whenever they like.. however downgrading to an iOS 4.x.x requires soft SHSH blobs..

Thank you for replying. You were probably working on that while we were all complaining about it not working. I read it and am still trying to figure it out. I’ll post a comment in the linked post.

hi i have a quesiton about the downgrade,
it doesnt work when i press shift+restore and then it says “the ipod “ipod” could not be restored because the firm ware is not compatible.”
i have the same problem…need solution asap
Try this worked for me (from 4.2.1 to 4.1 without cydia or tiny umbrella)
Go to this site (http://www.felixbruns.de/iPod/firmware/) and download the downgrade ipsw for your idevice to the DESKTOP
Plug in device and open iTunes
After sync , hold shift and press update
Search for file on desktop and open
After downgrade, iTunes will ask to update, press later
Reboots and done

Can I downgrade to 3.1.3 a US AT&T iPhone in London without the AT&T sim card?
In other words, is there a step after getting out of the recover loop mode, where I need a valid AT&T SIM card so that I can fire up Safari and get to jailbreakme.com?
plzzzzzzzzzzzz i need help
i entered itunes and restored my iphone 3g (4.2.1)
when pressed shift+restore
i’ve chosen the downloaded 3.1.3 without entering DFU mode
now my iphone isn’t working
the only thing happening is that it enters recovery mode when i plug it into pc
and itunes never recognizes it
plzzzz tell me what to do ???? 🙁
