I bought a used iphone thinking i could fix it. Unfortunately, it was more complex then i thought.

Here the the symptoms:

- Phone doesn't turn on without usb plugged in
- When plugged in, it goes directly into recovery mode
- I can put it in dfu mode
- itunes gives error 23 when trying to restore to 3.0 (in both dfu and recovery mode)
- itunes gives error 160x when trying to restore to other firmwares


- I can jailbreak with redsn0w (to 3.0) and with QuickPwn Rc3 to 2.0.2, but still stuck in recovery mode


This is what iRecovery is giving me:

I read on one of the threads here on how to fix a corrupted file system (something to do with fsck?) but don't know how to. Could anyone help?

Not sure if this will work for your situation, but this did help me get my iphone 3g out of recovery mode.
