(adsbygoogle = window.adsbygoogle || []).push({}); got a ps3 slim original hard drive 120gb switched to 250gb
downgraded with E3 card reader down to 3.41 from 3.55 ofw
hacked on 3.41 with psjailbreak2 (china clone)
couldnt use my authentic psjailbreak cuz site is down so no files to download and program my device, anyway.
backed up COD BLACK OPS with multiman v.1.4 (cuz the new versions say at the beginin NO PAYLOAD DETECTED, or something like that, so i stayed on 1.4 version. so when i start black ops
i get the black screen. ive tried patching it, and nothing, any help for this game. sorry for making this long.

Why are you on 3.41? Why didn't you just stay on 3.55 and use CFW? It's MUCH easier then using a jailbreak, I believe you need a special edited EBOOT for it to work on 3.41.

Although 3.41 is better .. 3.55 is less hassle
