Dude. Ive been on rebug 3.55 forever went to rebug 4.21 and could play all the newest games all night long. turn off the machine and then back on the next day and none of the games will boot past black screen. I went back to 3.55.3 and started patching eboots for newer games and was totally set, that is till i couldnt get black ops 2 working. Lastnight went back up to 4.21 played blackops 2 all night online even. Wake up this morning and black ops 2 and any other game i tried to boot would black screen.

Guess what firmware im back on today?

Can anyone shed light as to why this firmware does this?

if i installed REBUG 3.55.3, would i use toolbox to put it into factory service mode to do the bd remarry without a dongle??

im trying to go on to rebug 3.55.3
i do the 999 update no problem, but when i do the 3.55.3 install it says the file is corrupt?
it still blackscreens on 999 multiman

go to package manager install rebug toolbox from harddrive. Run the toolbox after installl and select enable QA flag. then with the 3.55.3 UPDATE.PUP on USB/PS3/UPDATE. Install the Update from the XMB.

I can't, all I get is a black screen when I click on toolbox or anything

Format your ps3 then try it again it worked for me.
