If your usb isn't working is only mainly from the ps3 didn't turn power to them but that usually happens during a downgrade and so keep trying all the steps over until you get them.
Also helps if you already have the JB dongle to second usb already plugged in during the downgrade
thanks for the advice i'll keep trying
and by the way i've also got a cechho2 model gave a crack at that one but when i went to backup bios the screen scrambled up but the backup was 100% success first i thought i bricked it but the downgrade seemed successful but the hdd doesnt seem to load all the way and i can not get video at all and controllers wont sync think i screwed this one up too
