This thread just saved me from going to 4.2.1 again and manually backing up all the data!
Thanks! Editing the file did the trick!

editing Info.plist didn't work for me at all when downgrading iphone 3GS from 4.2.1 (8C148a) to 4.1 (8B117). "iTunes could not restore the iPhone because the backup was corrupt or not compatible with the iPhone that is being restored", no sms data, no contacts, no photos.
so I'm out of luck, I guess. even extracting .sqlitedb files from backup with iphone backup extractor and copying them over after restore does not work. (some of the data does show up on the phone, but is mostly corrupt and unusable)

I have the same problem as kto, everytime I try I get the error "iTunes could not restore the iPhone because the backup was corrupt or not compatible with the iPhone that is being restored"
Any help would be appreciated.
04-18-2011, 02:19 PM #35SOLUTION - "backup was corrupt or not compatible" FIXED
***Never forget to manually create a backup of your latest iTunes iPhone backup before restoring/upgrading/etc.***

This worked great and definitely should be stickied! Not just for the iPhone 3GS. I tried it out using my iPhone 4S. I've been using 5.1 beta 3 firmware. When I discovered that the A5 Untethered jailbreak would not support 5.1 because Apple has patched it, I knew I had to downgrade. I downgraded very smoothly and restored all my settings from 5.1 to 5.0.1 easily. I am running Mac OS X 10.7.2, iTunes 10.5.2 and now iOS 5.0.1 firmware for the 4S.

It's insane how amazingly well this worked for me.
Am on the developer program and updated to 5.1 (after saving my blobs)
Untethered jailbreak came out and have been looking online for 2 WEEKS!
follow those instructions exactly and you won't have any problems.
** Also, download Plist Edit Pro, made it easier to edit. **
Forgot to add... TEXT MESSAGES ALL THERE pictures work PERFECT
