Hacking A few basic questions about updating CFW

[frogboy]

i'm currently on rogero 4.55 (haven't done anything with it in long time) and i'd like to go to rebug 4.81.2. had a few questions first

1) the rebug website says to make sure i have "spkg sig check patched and QA enabled" when i update, and i'm not sure how to do that.

2) will i lose anything by switching from rogero to rebug? i have a few .pkgs installed, and i used multiman for a few games with broken discs (thanks, baby cousins). i assume multiman will continue working afterwards.

sorry if these are dumb questions, i literally haven't touched my ps3 in several years.

You should already have tgat, just in case backup your nand/nor
mmOS->Select any file->Open in HEX viewer->[SELECT]->[START]->DUMP LV2(NO)->DUMP LV1(NO)->DUMP FLASH(YES)
And update to latest rebug.
You wont loose anything, just old cfw :-P
Cheers!
