Have you re connected the optical disc drive back up?
Some downgrades require drive to be installed or you will get errors/update loop.
When ps3 gets to the point that it failed the update & is going to restart, turn it off & re install drive
If you have drive installed recheck that its connected properly.
Dose the drive work? If the drive is faulty,not reading disks..this can make a update fail.
