Hello all. A short introduction: I've been a practicing member of jailbreaking since 2008 and have lots of experience overcoming issues. Except this one, I am stumped and need the help of the community. STORY: The other day I was doing my usual weekly Cydia updates (update all), which went fine. Later that evening, the phone died. After charging it back up, it was stuck in an infinite apple logo boot-loop. I've had these a handful of times before, on my 3GS and 4. I tried the "hold volume up for safe-mode" feature, but strangely it wasn't working. I then logged in via SSH with the 3 minute window (per reboot). I gathered some files off the phone. But then, something stranger happened. One time it rebooted, and went straight to the iTunes Recovery screen (iTunes logo with cable and arrow up). I have no idea how this happened. I never tampered with any system files. But now I cannot even get in with SSH to recover data or do anything else. **** PROBLEM: I am trying to restore this iPhone 4s v5.0.1 back to any 5.x (5.1.1 preferably). I have all the SHSH blobs local and remote. But iTunes / TinyUmbrella combo isn't working. I keep getting the "Error 1600". I've been searching google all night, and I've gathered on this board that this method isn't working anymore. (why not?) So I went plan B: Redsn0w Restore feature. I tell it yes 5.x to 5.x. After giving it the IPSW and it goes into uploading the files, it then comes to the error "Re-restore failed. You might have guessed the current FW incorrectly, and it may not really be iPhone4,1 etc etc. BUT I know that it really is that firmware. I know that 5.0.1 had 2 versions, so I downloaded both IPSW's directly from iClarified, and it still gives me this error. I never did an OTA (infact I installed a Cydia app to disable OTA just in case). Now, I'm stuck with a phone that's stuck in Recovery mode. No tools will kick it out of recovery. I can get into DFU, but not PwnDFU (4s cant do that apparently). Can someone please help give me some answers and/or guidance on what I should do next? Now that Apple has stopped signing all below v6.0, I don't want to restore above 5.1.1 because I cherish and depend on jailbreaking for so many things. Please and thanks to anyone who can help.
