Downgrade iOS 5.0.1 To 4.3.3, 4.3.5 On iPhone 4, 3GS, iPad 2/1, iPod touch [How To Tutorial]

[Miztory]

iOS 5.0.1 has been released - and, chances are, you may be looking to downgrade to an earlier version of iOS because of one reason or another. Today, we’re going to guide you on how to do exactly that so you can go back to whichever version of iOS you are comfortable with.



Before you continue, though, keep in mind that you can only downgrade if you have previously backed up SHSH blobs for whichever version of iOS (4.x and below only) you wish to downgrade to. This is because of certain security checks used by Apple to ensure people stick to the latest version of iOS. It is also important to note that as of this writing, iOS 5.0 firmware is still being signed. You can downgrade to iOS 5.0 as long as it is being signed by Apple. The moment Apple stops signing iOS 5.0, you wont be able to downgrade to it even if you have SHSH blobs saved for it. This applies to iOS 5.x only, explanation for which can be found here.

NOTE: This guide is not applicable for iPhone 4S since there is no public jailbreak available for it, yet.

Step 1: Download the version of iOS to which you wish to downgrade to:

Step 2: Connect your iOS device with your computer via USB cable. Boot into Device Firmware Update (DFU) mode. To do this, you will need to first turn off your device, press and hold Power + Home buttons for about 10 seconds, release the Power button while holding Home button for an extra 10 seconds. You’ll know when you’re in DFU mode, this is when the screen will go completely blank.

Step 3: Navigate to Windows > System 32 > drivers > etc on Windows or just etc on OS X. Locate a file named hosts, make a backup copy of it and then open it up with a text editor.





Step 4: Add the following code to hosts and save the file:

74.208.105.171 gs.apple.com



Step 5: Open up iTunes and choose your iOS device from the sidebar. While holding the Shift (on Windows) or Alt (on OS X) key, click on Restore and choose the firmware file you downloaded in Step 1.

Step 6: You may receive Error 10xx after doing this, but there is no need to worry about it.





You must download a program like TinyUmbrella or Fix Recovery, open it up and click on Exit Recovery to get out of the error.



That’s it!

If you followed the steps correctly, your device will now be downgraded from iOS 5.0.1 to the firmware of your choice. You now may want to jailbreak your device on whichever firmware you chose: use JailbreakMe 3.0 if you’re on iOS 4.3.3 for untethered jailbreak, or tethered jailbreak using Redsn0w if you’re on iOS 4.3.5. iOS 5.0 can also be jailbroken tethered, or semi-tethered using Redsn0w.

Last but not the least, make sure you revert the changes you made to hosts file in Step 4 above to start receiving future iOS updates normally in iTunes from Apple’s servers.

1. Sir when change the hosts file and i shift + restore the apple official firmware 4.3.3 it gives me error as 3194..

although i had saved my blogs for 4.3.3. and onward...

after that i also tried running the TU but still problem..

what would be the prob, any suggestion ..?


2. And when i try putting the custom firmware 4.3.3 into my i4, it successfully completed by first running the IREB prog, then meanwhile running the TU and then shift + restore to custom firmware but at the end when count down stats from 10 to 0 after full completion of downgrade from itunes my phone isnt turn on, mean it stuck into permanent DFU mode... and it only turn on when i go and put 5.0.1 Custom Firmware..

Pls Help Sir...

I did everything you said but i kept getting error 1. Anyway, i am on Itunes version 10.5. I have an iPad 2 GSM on 5.0.1 now but i have my Shsh saved on 4.3.3. Are you sure you restored your ipad 2 gsm, not iphone 4? coz i heard from a lot of people that ipad 2 on ios 5 can't downgrade to 4.3.3 even if they have their blobs saved. i am really confused now. i know this is way too much to ask but if u can make a video of your ipad 2 gsm downgrading to 4.3.3, a lot of us would be really grateful. this situation is really killing me slowly. Lol

Anyway, thanks man. I owe u big time!
