(adsbygoogle = window.adsbygoogle || []).push({}); I've installed RE-BUG 4.21.1 and now want to revert back to KMEW 3.55. i cannot simply install it from "System Update > Update via Storage Media" neither can i install it from the recovery menu. Im getting a little worried now that i cant revert back... I'm no noob to this stuff and have researched it and i see there is a 999 down-grader that RE-BUG have released along with this latest firmware. I've tried installing that and it wont work either, tells me it is corrupt. I've also read that i should have installed a QA package file, I don't know what this is or what its supposed to do but i didn't install it before going to 4.21.1.

Anyone who can explain to me how / point me in the right direction i would be very grateful to. Thanks :/

i was on this firmware yesterday install the rebug toolbox make sure qa flag is enabled within the toolbox the download the rebug 9.99 downgrade.pup update through xmb with 9.99 pup once updated and ps3 restarts install the rebug tool box again enable qa then install the new rebug 3.55 from xmb.once ps3 restarts then enable qa once more and install 3.55 orfw throught recovery menu.once installed then install knemu through recovery then enable qa check button combo and restart ps3.= back on knemu.
