iPhone 3GS stuck in recovery mode loop

[Cubytus]

Hello community,

since I wanted to get rid of a pesky bad signal issue after replacing a battery (all connections were visually checked and appeared to be OK), I wanted to restore using Semi-Restore so as not to force an upgrade on 6.1.3, knowing the jailbreak is necessary to keep it unlocked. However, Semi-Restore failed, and now the phone is stuck in a Recovery mode loop.

I tried to use the latest Tiny Umbrella to exit from it, but it wouldn't work, and the phone keeps on rebooting in Recovery mode.

What can I do to get out of this mode and proceed with redsn0w?

I had a similar experience. To resolve it I restored the phone back to iOS6 from iTunes, then installed the GM of iOS7. Once I did this, the phone saw my iCloud backup from yesterday morning and restored everything.

Not sure if it was the best route, but it worked for me.

eta: just saw the you said they WEREN'T backed up. Uh oh.

What wasn't backed up? I never said anything about backups. Only, it is not possible to restore to iOS 6.1.2 since 6.1.3 is out for this model. Hacks are necessary.

I tried this sequence, on Windows (ew):

1. Download & install older iTunes version (10.0.5)
2. Download iFaith, latest version
3. Connect iPhone and fire up iFaith
4. Retrieve stored SHSH blobs for 6.1.2. Luckily, I must have stored them before because I got success there.
5. Build signed IPSW from generic IPSW
6. Enter Pwnd DFU mode (just follow iFaith's instructions)
7. Quit iFaith & disconnect iPhone
8. Fire up older iTunes & reconnect iPhone
9. Wait for it to be recognized.
10. Hold Shift + click restore.
11. Choose created, signed IPSW and let iTunes do its job.

I now get an unactivated iPhone with iOS 6.1.2
Stay tuned for next step.
