problems flashing firmware to c139

I thought that having the debug cable plugged in might have affected things but it seems that is not the case. I also noticed something strange. When I plug in the battery the screen goes to white without me even pressing the power key. Could this be because the normal phone might jump to 0x2000 when the battery is plugged in? I know that a special screen is shown when the power supply is plugged in as well. Maybe the white screen is the first steps of LCD initialization and somehow things are going wrong after that. I will test the hello_world compalram/highram firmwares and ensure they work properly. Thanks, Craig
