We were able to update the ROM and everything worked fine but even after the upgrade the machine still does not allow for a hard reset because the screen flashes by too quickly. Eventually he is going to call Dell to exchange the machine but for now it works fine. Not sure why this happens but it is definately a A12 thing. Hope this helps.

Thanks very much for the replay! I have tried hard to figure out what to do and your answer gave me some hopes! Please tell if possible what king of SD card u used, because I have tried with a 256 Mb one from my Canon Camera and I only got a white screen with a blue band on top where was writen "SD Image Update AXX_G3".
Can you provide some more details about the bootloader procedure?
I found on the forum the entire disscution about the exact method, followed very carefully each steps, but I got stuck.
Please help!
