Backup doesn't exist anymore after 4.3.5 upgrade

[alf92ru]

Hello everybody,

I have an Iphone 4. I have the following baseband : 04.10.01. And a Jailbroken Iphone 4.
Yesterday, I've tried to move from 4.3.2 to 4.3.3.

1. First, I've made a backup with ITunes.
2. Then, Ive got the IPSW of the 4.3.3.
3. Then, as explained in a tutorial, I've moved to DFU mode in order to install 4.3.3.
4. As I found it impossible to get out of the DFU mode (I've tried TinyUmbrella, IReb, ...), I've decided to upgrade to 4.3.5 (bye bye untethered jailbreak).
5. After 4.3.5 installation, iTunes proposes me to restore from backup. When I choose my backup in the list and click on "Next", after a few seconds, I get an error message from iTunes : iTunes has not been able to recover the xxxx iPhone because the backup doesn't exist anymore (sorry, I got the message in french and tried to translate it so it may be not the exact error message). When I go to the "Documents and Settings\....\Application Data\Apple Computer\MobileSync\Backup" folder, I have a "56dd772a21928e926248f164627b6b287fae00b3" folder and in this folder, I have some files whose date and time match the date and time of my backup. I've been to the "Documents and Settings\...\Application Data\Apple Computer\Logs" folder and opened "asl.131341_13Aug11.log" file. Here is an extract of what I get at the end of the file :

I've not touched the Hosts file at any moment during the upgrade to 4.3.3 or 4.3.5 (unless TinyUmbrella does it itself). Is it the reason why I have this issue ?

Do I have to try to get back to 4.3.2 and then try to restore back ? If yes, how do I have to do ?
Should I try to use another computer ?

Thanks in advance for your help because I would like to get back at least data of my apps.

I've read on another forum that uninstalling/reinstalling iTunes and "Apple software update" apps could solve my issue. Before proceeding, what do you think ?

Thanks in advance.

Go to the MobileSync\Backup folder, if your backup is not in there it's gone for good, there won't be any way to recover it

Hello,

You're perfectly right, my backup files are not in the MobileSync\Backup folder anymore.
So I just have to sit and cry :-(

Thanks for your help.

I feel your pain, same thing happened to me. I figured that iTunes would store ALL backups, but if you have a device with the same name as a different device, it overwrites the old backup with the new one. I lost about a years worth of photos, contacts and gamesaves once and I felt like crying.
