jailbreak – iOS 8 restarts every 5 minutes with a black screen after iFile attempts to archive 4GB of files

Yesterday I wanted to copy the images I have on my iPad Air 2 with iOS 8.1 on my PC and I could not think of anything better than archiving ~ 2000 images with a total size of ~ 4 GB with iFile. After 1 hour of the "Compressing …" screen I forced the closed iFile. The reopening worked well and no file was created, it's not surprising. I was curious to know if the space occupied by the file was clear, but I did not check the initial free space while at present it showed 17 GB. So I used a pinch that I was always using well to restart my iPad. And now it is stuck in an infinite process:

  1. Boots of the device.
  2. The Apple logo is replaced by a black screen that glows slightly.
  3. During the system uptime, the device can respring several times (I guess it's a respring. It shows the Apple logo for about 10 seconds, but it does not reset the SSH connection).
  4. After some time (average of 5 minutes, the maximum recorded is 9 minutes) the system is blocked and we return to point 1.

Here are some observations:

  1. After reopening iFile after forcing the shutdown, the disk space of the user's partition had 17 GB free, the disk space of the system partition had ~ 1 GB of free space.
  2. I can still SSH on the device during system uptime, access any folder, copy files, execute commands.
  3. System failure creates 3 files in / private / var / logs / CrashReporter /:

Additional details:

  1. I'm not using iTunes, iCloud.
  2. Entering safe mode does not solve the problem. In fact, I do not even know if I'm in Safe Mode due to the black screen.

I guess that iFile has messed up some files or their permissions, but the system works fine for at least 5 minutes. Why is the screen black? How can i fix this?

Edit: here is complete crashlog.

Editg 2: As I mentioned earlier, I can execute commands through SSH. This is what I see when I execute. respring I send. The following output appears after the respring is performed:

rm: can not delete `/ tmp / RestoreFromBackupLock & # 39 ;: permission denied
rm: can not delete `/ tmp / SpringBoard_reboot_flag & # 39 ;: permission denied
rm: Can not delete `/ tmp / gg_address': permission denied
