I do not recommend trying a bunch of random firmwares as most bricking occurs while flashing the firmware, the less you do it the less your chances of a brick are.
I suggest you tell us what firmware you are running and maybe someone with the same firmware can tell you what they do.
Im in 3.55, trying to go to 4.55, i nerd your help here.
