Hey there guys! Sorry to bother you all with my problem, have been following posts on this forum for some time now, so I tought some of you may be able to help me out. So,basically, I have PS3 Slim CECH-2504B with Rebug 4.84.1 LITE installed on it. Wifi/Bluetooth chip is faulty on it. I wanted to upgrade to Rebug 4.84.1 REX so I used MFW Builder 0.2.1 to create CFW file without Wifi/Bluetooth check, and because USB ports are also faulty (controller works just fine, USB memory ain't), I burned update to CD and placed it in console. I started update from XBM, but got stuck in Update Loop with error about wifi/bluetooth, like the MFW Builder did not worked well...? So I read online for one way to exit the update loop is to remove HDD and format it. I hooked up HDD to pc, formated it, put it back, got asked for 4.84 update storage, but nothing works. So, anyone have any idea, how to stop the update alltogether and return to old firmware or something?
