Hey everyone need a little help here. I just have the touch pro which is branded under 3 network in australia. So if i wan to flash to unbrand/official rom do i need to HardSPL it first? Or i can flash it right away?

So far anyone face problem with htc touch pro where the phone doesnt wake up from sleep mode even u press the power button? And u need to dispatch the battery out to on it? I m on the recent rom update now. wonder is a bad flash or its common for this to occur?
