iPhone 4S recovery mode
It keeps freezing/crashing and when restarting enters recovery mode. This has forced me to restore the phone for the 4th time in as many days! Any ideas what has happened?
I recommend to remove the firmware file (a combination of hardware & software) and place it into DFU Mode (device firmware update) and let it restore.

If this doesn't fix the issue, it needs a repair/replacement.
