Accidently updated my ps3 a year ago, so purchased a new ps3.

PS3 Specs: CHECH01 with 1.90 OFW

Trying to update it to 3.55 OFW then CFW but i keep getting the 8002f997 corrupt data error at 70%.

Anyway to fix this? I've already fixed the YLOD/RLOD on it.

try updating to 3.41 and then try 3.55 ofw then jb
