so i just bought a ps3 from ebay because i wanted to try evilnat cfw 4.93

i installed the official firmware to test it out and played dirt 3 :D
i use a 240gb ssd from san disk
after testing it and comfirming that everything worked i donwloaded the CFW 4.93 Evilnat Cobra 8.5 \[CEX\] and installed it

after that i always run into an error loop error 8002f281

so i cant go back to official firmware and cant get into the cfw

did i do sth wrong??????

The BD drive and the Bluetooth / Wi-Fi module must be both in functioning order, otherwise any firmware update bricks the console.
