How-to Downgrade from iOS 4.1
SPONSORED LINKS
Apple released iOS 4.1 firmware last week with many new features like HDR Photography and Gamecentre . Inspite of repeated alerts from us and the Dev team , many of you must have upgraded to iOS 4.1 and lost your jailbreak for iOS 4.0.1 . This tutorial will help you get back to older firmware and restore your Jailbreak .
#Important : You need your SHSH Blobs for the downgrade . Learn how to create SHSH blobs.
Downgrade Steps for iOS 4.1 on iPhone :
- Download your SHSH blobs from Sauriks server on your PC. For that you have to download Tiny Umbrella .
- Select the “Advanced Options” check box. Now under “Device/Version”, select the firmware version to which you want to downgrade (ie your previous JB version) as shown in the image below.
- Now click on “Save My SHSH” .This download and save your SHSH blobs from Sauriks’s Server.
- Now download the firmware you want to downgrade . iOS 4.0.1 in this case.
- Switch your mobile to DFU mode.
- Now Run TinyUmbrella and select “Display SHSH” . After doing that , Select “Start TSS Server” as shown in the image below.
- Launch iTunes . Older version preferably [pre iTunes 10 release].
- Plugin your iPhone and hold down SHIFT Key [Win]/ ALT Key[Mac] as you click on Restore.
- Now you phone will be downgraded to older iOS version of your choice.
- Open Tiny Umbrella and click on “Kick device out of Recovery” . Now you are done
Note :
- iTunes may give you the following error messages [error 1011, 1013, and 1015]. Just ignore them , you’ll be just fine.

Thanks for the guidance. Is it possible to used another person SHSH iOS 4.0.1 to downgrade our firmwware?
I guess no , why not give it a try , nobody has answered this question yet , though asked many time …. i would really like to know the answer . it that was possible , we can actually host the SHSH file on our server for everyone to download … that would be great …
hi could somebody send me their shsh blobs for ios.4.1 and
4.2 i think i have found way how to change the blobs to make it work on other phones so if you can send me those i will get to test it if its possible.
Ok, I understand ! Is it possible to have back the previous bb version ( ie. 01.59.00 ), when accidentally the firmware upgrade, upgrades the bb. version too ???! Yes, I did shsh for both firmware versions …
Please help on that !
Appreciated
Im sorry, but I do not follow the whole situation clearly apparently. I bought my iphone4 and it came with 4.0.2. Sothere was no hope for JB. Now I updated my firmware to 4.1 using tinyumbrella and conserved my shsh blob. But this thread is saying I did the wrong thing or what?
OOps no … did i make that statemnt . I think you just did the right thing … now wait for iOS 4.1 JB …
Ok sweet. Thank you
Ok, it’s works, but what about unlock baseband? How to downgrade 05.12.02?
guys<< if u already upgraded to ios 4.1 there is no hope,, this method is useless,,, u have to save ur shshs before the upgrade,, but since u already upgraded,, no hope,, so good luck
I have saved my shsh before updating from 4.0.2 to 4.1.
I did not preserve the baseband, so it is now
I follow the procedure using tinymbrella to downgrade the firmware back to 4.0.2 successfully, but the baseband is not revert to the 1.59 version.
Did I miss out some steps ?
Well I did it! It worked fine with me and I upgraded to 4.1 . I am using a 3G so it runs slower so I took it off. I’ll just wait for the next jailbreak but it works.
Hi there! i have bought onein the US with 4.0.2 inside. Then i have done the upgrade to 4.1 from the itunes app.
Question is… am i able to go back to 4.0.2, and then upgrade following the procedure, or is useless?
thanks for the help, and keep up the good work. Better having the JB one day later, than a buggy app for this marvellous telephone…
This helped a lot I’m downgraded to 4.1 now, but I’m just wondering will there be a 4.0.2 update for jailbreak when I want to update it back?
It always seems fine till I hit “restore” on itunes 9.2.1.
But after a while of extracting file,
it says unknown error occurred…..
Any ideas? Thanks.
This is a great step-by-step that anyone can follow. However, since “anyone” may be following it you might want to expand on step 9 a little. What kind of file is the user looking for to downgrade to, etc. Cheers!
So I have an iPhone 4. When I first plugged it in I had to upgrade to 4.0.2 and have since upgraded to 4.1. If I just saved my SHSH today, does that mean I am SOL until a 4.1 jailbreak is released?
Just bought an iphone 4 with ios 4.1 can I downgrade it using this method and then jailbreak the phone? Or do I have to wait for jailbreak for ios 4.1? Is it available yet?
Thanks!
nope , you cannot downgrade below your base firmware , ie 4.1 …. wait for JB , it nearing completion. Subscribe to our emails … we will send a alert when its done
Same here, got an iphone 3 wth os 4.1 i want to jalbrake frst time. Do I haveto wait for 4.1 JB or is there a orking method to downgrade and do firstTimeJailbrakng from 4.1 ?
cheers
hello there,iv tried to downgrade my iphone 4 from 4.0.2 to 4.0.1,but keep getting the 3002 error,help?
hi
i had gotten an iphone which had ios4.01. got it unlocked and it worked fine until i reset and erased all settings . no it is stuck to the apple logo. do you think i can still do something to get it back to 4.01 and jailbreak it again.
i would really appreciate your help.
I had my phone jailbroken already and had clicked on the “make my life easier” link on cydia, they say they have no shsh for my phone which is now on 4.1. Theres no way to restore it to 4.0?
umm if i backed up files from my 3g would it be able to downgrade an iphone 4 firmware? or would it be to different
Hey is there a unlock + jailbreak out for iphone 3g version 4.1 (8B117) Modem Firmware 05.14.02 ? if there is can anyone email me and let me know how to?
yes we have a jailbrek , btw have you jailbroken it before . see the home page for the tutorial
Sorry buddy! No unlock for iOS 4.1 (BB 5.14.02) so far. Your iPhone is just an iPod touch till then.
oops forgot to put my email .. krushol@aol.com .. plz no spamming..
I have an iphone 4 with OS version 4.0.2. Where do I begin!!! I can’t afford to ruin my iphone 4. I do have an iPhone 3gs. Would it be easier to switch to my older iPhone 3GS and jailbreak that one? Or, should I jailbreak my iPhone 4 and if so, where do I start?
So I just recently found out about Jailbreak and decided that it would greatly support my phone needs. The problem is that I have already upgraded to 4.1. Is it possible for me to revert to 4.0 or, is there a future for a jailbreak for 4.1?
Hi! Wait for a baseband (5.14.02) unlock till ultrasn0w finds some solution. Till then explore the various options of iOS 4.1 as you can easily JB this firmware now with sn0wbreeze (PC) or redsn0w (MAC). Your iPhone is only an iPod touch now till unlock is done.
Hi I have the same problem have you find a solution yet?
Thanks
hey i just purchase a jb software but before purchasing i didnt realise that jb cannot unlock iphone4 4.1, so what shall i do for my refund
I have a iPhone 3gs iOS4 Baseband 05.12.02. I had unlocked, and jailbroke it under the old baseband, but then one day it got stuck on the apple logo screen, and I restored it thru itunes. I recently jailbroke it again, but can’t seem to unlock it. Is there an unlock for this baseband?
I currently have iPhone 4 ios 4.1 that I have jailbroken and the baseband is 02.10.04 so can I downgrade the phone cuz this article says nothing abot the baseband and as everyone knows the unlock for this baseband is yet not available. Please help!! THANK U!!
