I have a simple question and I wont take it for granted. Im on kmeaw 3.55 and with all the CFW downpour recently, thinking about going to Rogero 4.30 I have an old model 80GB FAT CECHK06. Its was from singapore and had the buttons 'X' and 'O' with reversed functionality. I used Rogero's Button Changer to set them as appropriate. Now I wonder is this could impede my planned ascension in CFW! I have no flasher and cant afford to risk a brick. These new CFWs seem to be so sensitive and moody, requiring Dehashing and QandA...etc!!
