Data recovery - Restore backup of old synchronized items
I wanted to share my experience of data recovery.
I went through a few 1.1.1->1.1.3 upgrade runs on my phone. The upgrades were all successful. But in the end I found out that somehow I lost all my data when I went through the process. I think at one point I had selected Restore instead of Update in iTunes when I did the 1.1.2, but it's all kind of a blur.
On one of the upgrade runs while I was at 1.1.2 I connected to iTunes and it saw the phone as "untitled phone" and asked if I wanted to create a new phone profile or restore a backup. I went with a new phone profile and then did a sync. Bad idea because it replaced my previous good backup with all my data. I didn't catch that until it was too late.
Anyway after the 1.1.3 upgrade I attached the phone to iTunes again and it didn't recognize it so when it asked if I wanted to restore from backup, I thought, cool I'll just get my data back. Well it restored the the useless backup and it updated my phone's firmware OS and BB!
I thought I was hosed because I hadn't heard any success stories of unlocking 4.03.13G baseband. Fortunately, I used the anySIM 1.3 Beta and got things working on 1.1.3 with the new baseband. But still I was without my data and the backup iTunes had was useless.
Well, remembered I had a backup image of my hard drive from a day ago that still would have a current backup of the iPhone data. But what could I do with that? I scoured the forums in the usual places and found some info about getting data out of the .mdbackup files using converters and python scripts.
Eventually I came up with the idea to just drop into the iPhone backup folder into "C:\Documents and Settings\User\Application Data\Apple Computer\MobileSync\Backup", its the one with the iPhone hash string 5adur9osjfa09875a4... whatever. When I opened iTunes again and went to Edit| Preferences| Syncing tab I saw it found the old (good) backup.
Then on the iPhone I just did a Settings | General | Reset | Erase All Content and Settings. The next time I plugged in the phone into iTunes it asked if I wanted to restore from my good backup and I let it do it. It worked this time and I have all my data back. Hooray!
I hope this helps someone out there who stumbles around with their iPhone update like I did.
