Boots to Apple logo, can't access filesystem
My iTouch 4g was working just fine until two days ago. I hadn't installed any new Cydia packages, hadn't updated any (no updates were available), nothing had been changed. The device is running iOS 5.1.1
I had the following Cydia packages installed:
AppSync for iOS 5&6
I believe the tweak RecoveryGuard is what is causing my current issue. This tweak makes the hardware fool iTunes into thinking it always has the latest version of iOS. This prevents the device from entering Recovery mode. I've been able to get my device to boot into Recovery mode, despite this tweak, but iTunes doesn't see that the device is connected. I also tried iTools, iRefone, ReiBoot, iFunBox and others and none would detect the device. The only apps that would detect the device are redsn0w and TinyUmbrella.
I attempted to restore the device using the Restore option in redsn0w but it didn't work. The device would seem to be preparing for the restoration but would boot up and show the Apple logo before redsn0w finished uploading data to it. I can't access the filesystem since none of the programs for that would detect the device, so I can't manually remove any Cydia packages or Sources and I can't SSH into the device either.
I've tried with the device booted (well, with the Apple logo still on-screen when it should show the GUI) and also with the device in Recovery mode, DFU mode and Pwned DFU mode.
Is this a good question?
