RE: Flashing Power Indicator LED
Yes the network cable is properly attached and I can make and receive calls with the phone.
When I try to update the firmware with the by you suggested rom file I got the following response from the phone:
Update Failed: Incompatible OEM device.
The current firmware version is: 28.71.188.9
