[Guide] iPhone\iPad 2 firmware too old to restore backup fix

[iNeoTom]

Anyone who has been on the new 5.1b2 firmware for example and downgraded to 5.0.1 for the up and coming A5 jailbreak

You will be familiar with this screen flashing up when you go to restore your iPhone\iPad 2:-

So doing some digging around on google i found a really handy easy to use guide to get your backup back on your iPhone with just changing 2 part of one file

So here we go.......

1. Navigate to your itunes iphone backup folder:-
WINxp -

[COLOR=#303030][FONT=Helvetica Neue]C:\Documents and Settings\<username>\Application Data\Apple Computer\MobileSync\Backup[/FONT][/COLOR]

WIN7 -

[FONT=arial][LEFT][COLOR=#000000]C:\Users\<username>\AppData\Roaming\Apple Computer\MobileSync\Backup\[/COLOR][/LEFT]


[/FONT]

OSX -

[COLOR=#303030][FONT=Helvetica Neue]~/Library/[/FONT][/COLOR][COLOR=#333333]Application Support[/COLOR][COLOR=#303030][FONT=Helvetica Neue]/MobileSync/Backup/[/FONT][/COLOR]

* Insert your own windows username where it says <username>
** Some of these folders may be hidden btw

2. Find the most recent backup, this reflects the backup in itunes with no date (for me it's "iNeoTom's" without any dates next to it in itunes, and most recently modified date in the backup folder)

3. Theres a bunch of strings/files here, scroll down to info.plist (or just click on the top one and hit the "i" key on your keyboard

4. Open notepad (or PLISTs for OSX) and drag the Info.plist

5. Near the begining, find these two strings...

<key>Product Version</key> <string>5.1</string>

<key>Build Version</key> <string>9B5127c</string>


--The value after the versions will differ depending on what version you were last on when you backup up, I'm assuming it was 5.1b2, though this method should work retrospectively and for future updates.


6. Now change these values to reflect your current setup e.g.

<key>Product Version</key> <string>5.0.1</string>

<key>Build Version</key> <string>9A406</string>

Product version and Build version can be found on your recently downgraded iPhone\iPad 2 in

Settings-General-About then go down to Version in brackets is the Build number :)

7. If itunes was open, it will still not recognis the backup, so restart itunes.

8. Backup should work fine now when you restore from it!

Hope this help atleast someone out on here it really helped me out

Just tried to downgrade to 5.1.1 from OS6 today.... ouch. Got into the plist fine, permsissions are granted, files were renamed, and now when I try to restore from backup with the downgraded plist, it says the backup is not compatible or corrupt... Any thoughts? Thanks!
