I was trying to update the firmware of my GS-625M and I've had a problem with the conexión of my PC:the system has fallen down completely due to an electrical problem.
Globalsat GH-625 was in process to update （at 50％ more or less） and due to the fall down of the system (and the lost of conexion) it is completely "died" and now I can´t switch on.
I've tried to press up + down and power buttons at the same time, but it doesn't switch on.
What can I do? Any suggestion?
