I've got an Error at chapter 1, part 4,´5, and 6. After i put in the sd card with update.bin, and started my ps3, all blue led's are glowing. after i changed the switches, reset it, and pressed start, the 2nd, the 5th and the 6th blue led's are blinking. i've shut down my ps3 and put the sd into my pc. there is a log-file on the sd, with the following error:
backup PS3 BIOS.
fail to initialize PS3 BIOS.
I didn't have started the downgrade process (as you said), because i dont have multiple valid backups.
So can some1 help me to fix this problem?
