I read your reply on another post while I was researching my problem.
I tried to update my system with Sony's OFW via internet, as well as via USB. [/PS3/UPDATE/PS3UPDAT.PUP] I made sure that my USB drive is FAT32 formatted as well. For both instances, it gives me the same error:
This data is corrupt. (8002F2C5)
I have absolutely no idea what I'm doing wrong, I'm sure it's something very simple, I'm overlooking... but it's driving me nuts!
Thanks for your reply and in the meantime, I'll keep trying.
