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:

  1. Run the TinyUmbrella
  2. 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.

iPhoneHeat July 7, 2010, 8:23 pm

Use the Kick out of recovery mode button using TinyUmbrella

mhuang July 7, 2010, 8:26 pm

I did, but the phone didn’t restart like it should.

Still showing the connect to iTunes.

mckinneycm July 7, 2010, 8:53 pm

Same here. I clicked “Kick Device out of Recovery” and it’s still showing the connect to iTunes screen.

iPhoneHeat July 8, 2010, 11:23 am

TinyUmbrella Links are updated now.. Older version has this problem..
Sorry for the inconvenience.

mhuang July 7, 2010, 9:44 pm

iTunes keeps telling me that I need to restore so that I can use my phone…

Freepass July 8, 2010, 3:23 am

close all the programs and try the whole process again.also try to use different usb port

chinacatgd July 8, 2010, 10:48 am

i updated my 3gs 4.0 w/new firmware 05.13.04 how can in jailbreak my phone

tim July 7, 2010, 8:58 pm

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

iPhoneHeat July 8, 2010, 12:09 pm

Thanks for the input :)

tim July 9, 2010, 12:02 am

*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.

CoolGuy July 18, 2010, 9:42 am

how did you do that?

CHRISTABELL July 19, 2010, 4:53 am

What tinyumbrella did u have to download? the latest one has a mirror 1 or 2.

mckinneycm July 7, 2010, 9:23 pm

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.

iPhoneHeat July 8, 2010, 12:10 pm

TinyUmbrella Links were not up-to-date when the guide was published.. Sorry.

Links Updated!

iPhoneHeat July 8, 2010, 12:12 pm

you can’t downgrade 3GS to 3.1.2 without 3.1.2 SHSH.
with 3.1.3 SHSH you can downgrade to 3.1.3 only

iPhoneHeat July 8, 2010, 11:20 am

You can’t, atleast for now..
wait for the Spirit Jailbreak update that is expected soon

Tomsiphone July 8, 2010, 5:58 pm

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

justabrake July 8, 2010, 6:00 pm

this is what I followed >http://www.saurik.com/id/12#howto

iPhoneHeat July 8, 2010, 6:01 pm

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

Tomsiphone July 8, 2010, 6:03 pm

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

Tomsiphone July 8, 2010, 6:01 pm

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.

justabrake July 8, 2010, 10:12 pm

I think you have to run it as administrator

Mansoor July 8, 2010, 9:54 pm

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

Mansoor July 9, 2010, 3:54 am

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?

iPhoneHeat July 9, 2010, 8:37 am

Simply Keep retrying

iPhoneHeat July 10, 2010, 5:52 pm

Make sure your have Java runtime environment installed

NoService July 10, 2010, 9:57 am

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.

iPhoneHeat July 10, 2010, 5:58 pm

can’t downgrade without SHSH

r0cstar July 10, 2010, 1:02 pm

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?

iPhoneHeat July 10, 2010, 5:59 pm

iPhone 3G does NOT required SHSH blobs to downgrade :) did you read what that step says?

r0cstar July 10, 2010, 2:28 pm

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.

iPhoneHeat July 10, 2010, 6:01 pm

any error?

r0cstar July 11, 2010, 3:02 am

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??

r0cstar July 11, 2010, 9:23 am

im running on windows 7 does that have anything to do with it?

r0cstar July 11, 2010, 9:50 am

what am I doing wrong??

iPhoneHeat July 11, 2010, 4:59 pm

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

nerd1121 July 10, 2010, 3:06 pm

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?

iPhoneHeat July 10, 2010, 6:02 pm

use the kick out of recovery button on TinyUmbrella

nerd1121 July 11, 2010, 12:03 am

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!

zapakhpala July 11, 2010, 12:09 am

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.

iPhoneHeat July 11, 2010, 12:17 am

why one would extract IPSW?

zapakhpala July 11, 2010, 1:43 am

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!

Henrik July 11, 2010, 2:04 am

I just did this on OS X and it worked great! Thanks!

zapakhpala July 11, 2010, 5:53 am

Downloaded older iTunes and was able to jailbreak with Spirit. Nice guide; thanks!

r0cstar July 11, 2010, 10:58 am

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??

iPhoneHeat July 11, 2010, 5:32 pm

if you let iTunes backup the last time you connected your iPhone then simply restore that backup

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..?

iPhoneHeat July 13, 2010, 12:29 am

3GS User July 18, 2010, 2:57 pm

Hi mate, I’m still getting the same error code 3014, its becoming frustrating. Have you managed to downgrade yet???

myname July 19, 2010, 7:00 pm

No….i have another Q,is it need to download “shsh blobs”??Is it also 1 of the sofware?

Villiard July 18, 2010, 6:57 am

What is the error 3194 and how fix it?

I have a (MB) Ipod Touch, and I did all the steps to downgrade it, but it doesn’t work!?

Can someone help me please?

iPhoneHeat July 18, 2010, 12:16 pm

for iPod Touch MB there’s no need to set up TSS server..
put iPod into DFU mode and restore..
or try without DFU mode

CoolGuy July 18, 2010, 9:41 am

Everything worked except when I cannot kick my iphone out of recovery because the button is grayed any suggestions??

iPhoneHeat July 18, 2010, 12:19 pm

you can save SHSH 4.0 or older only if you have saved them via Cydia when they were being signed by Apple

Ismail Sahil July 19, 2010, 1:08 am

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?

iPhoneHeat July 19, 2010, 6:07 pm

did you read the complete guide?

3GS User July 19, 2010, 3:35 am

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!!!!

iPhoneHeat July 19, 2010, 6:13 pm

Make sure TinyUmbrella has cached SHSH blobs for the firmware you’re downgrading to.. (Click Display my SHSH to confirm)

3GS User July 19, 2010, 8:38 pm

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.

iPhoneHeat July 20, 2010, 11:46 pm

Are you on Mac?
The developer himself confirms that Mac users are encountering this error.. Hopefully it’ll be fixed in future update

Ismail Sahil July 19, 2010, 8:58 am

and then use Spirit to jailbreak

CBeLL July 19, 2010, 11:33 pm

Ok so I just bought an iPhone 3GS from someone that had already upgraded to the new firmware. It doesnt have cydia so I dont have the SHSH blobs. How do I get them, or Can I??
THANKS!!

iPhoneHeat July 20, 2010, 11:52 pm

did you read the guide?

Shawn July 21, 2010, 11:15 am

Can I use my SHSH blob from cydia to downgrade a different iphone 3gs? Or will it only work on my 3gs?

iPhoneHeat July 22, 2010, 5:03 pm

SHSH cert. is unique for each device

Joviano July 22, 2010, 9:28 am

I tried this from iOS 4.0.1 to 3.1.3 CFW, but it says ‘an unknown error occured (13)’. Does this mean that I can’t put my 3GS back to 3.1.3?? Help!

freepass July 22, 2010, 11:41 pm

Hi,I have iPod Touch 2G MC model with 3.1.2 already GB with Blackrain(annoying tethered GB).How can I upgrade it to 3.1.3 so I can GB with Spirit?iTunes keeps giving me an error message 1394.

Joviano July 23, 2010, 3:24 pm

Aww mannn, I tried this many times and iTunes keep giving me the ‘an unknown error occured (13′ notification. My 3gs is still on 4.0.1 OS. Is it because that I’ve jailbroken it with SPIRIT before?

mboe July 25, 2010, 11:18 am

If SHSH blobs not safe and IPhone locked after updated to ios 4 from 3.1.2 jailbreak version, is it possible to unlock? Please help. Thank you bro.

iPhoneHeat July 25, 2010, 6:12 pm

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

Joviano July 25, 2010, 11:30 am

Thank you soooo much iPhoneHeat!!!!! :D I successfully dowgraded my iOS4 back to 3.1.3 and jailbreaked it! Woohoo!!

yes you can jailbreak and then unlock with UltraSn0w 0.93..
Just avoid iOS 4.1 (still in beta)

Will August 1, 2010, 10:37 am

I have an iPod Touch MB model on iOS 4.0. You say that for non MC models you don’t have to have SHSH blobs saved, but I when I select the 3.1.2 ipsw, I get to the point where it verifies with apple, then I get the error 3194. Is there any way to fix this or should I just try 3.1.3 instead? Please help

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.

thanks

Vic August 2, 2010, 7:49 am

Terre August 12, 2010, 2:55 am

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?

Terre August 12, 2010, 3:03 am

Sorry, being stupid, problem solved. ;)

Shouldn’t do these things when it’s late.

yurdzdroids August 17, 2010, 5:53 pm

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?

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…”

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).

PyBrick October 9, 2010, 9:44 am

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?

iPhoneHeat October 9, 2010, 12:21 pm

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.

brianc December 6, 2010, 1:39 am

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?

gmm3 November 4, 2012, 11:25 pm
