Charging LED flashing and cannot connect serial

Hi,
I know this has been on some other threads but I have tried all of the other solutions to no avail. Here's the story

GSM1400 working fine and writing data to host IP
Needed to change a setting
Connected to serial
LED chrg starts flashing like crazy (LiPO fully charged and is industrial std)
Pressing resent does nothing
disconnecting serial stops led flashing, on light is green but nothing happening on the board
Connecting 5v to Vin, led green...attache battery and chrg led falshing - nothing happening.

Does anyone know a way of resetting this board other than the double press - or is it now dead??

Help as I am halfway through a big project and I need to know if this is a GSM board fault or something I did-

P
