! yeah ! the only thing I didn't do , was logging out from multiman ! I shut down the system directly .
when I go to recovery mode , the only option open is reset system !!!! OFW3.55 on DEX right ?!
**Edit : I've managed to install OFW through recovery :D
now I'm on dex because debug setting appear under XMB.
thanks for all your help ppl ! though every thing I though was wrong , I owe u my mental situation about Gaming :D
only another question ! is intalling lower lvl Frimwares like CEX ? can't install 3.55 on 4.21 directly ?!
