Did not go to OFC or dehash it
Yeah me too... I think dehash it's only for downgraded consoles and I am not sure if is mandatory. I was on TB CFW -> OFW 3.55 -> Rogero CFW 3.55 v3.7 -> Rogero CFW 4.21 no problems at all.
By the way I read some comments about Medal of Honor: Warfighter.
Looking at the original PARAM.SFO it's for FW 4.25. I do not know if they use similar or different keys but it was not working.
I installed the update v1.01 which is for FW 4.10 and it worked just fine from External Drive.
