Can't flash 8210 because of MADos

I put a MADos flash on to an 8210 and now I can't flash it because when you press the power button for it to start flashing it turns on because for some reason you don't have to hold in the power button to turn it on with the flash file I've got on it. :-?
Does anyone know what to do in this situation?
Thanks

Hi,

Try not pressing that button, but insert the battery loader instead.

Or the good old paper trick, put some paper between Ur phone and the battery contacts, so U not have power yet.

Pull it out at the time U need to start flashing.

Good Luck
