New to the forum and to Arduino. I bought the GPRS V2 shield last week and it was working perfectly…until…I tried to update the firmware. After fighting with it for a few hours I got the firmware update to take, but…I may have stopped the process prematurely (because it sure looked like it was done). Now, it will not power up by the power button (or through software).
The green power light is on (by the power button), but when I press the power button, the red status light never comes on and subsequently, it never initializes. It’s like the shield has power, but what initialization routines the SIM900 tries to run don’t even get called.
I am guessing a bricked the damn thing, but before I run out and buy another one, any suggestions? If I could get it to power on, I may be able to re-flash it, but the flash utility can’t see it because it is waiting for it to power up.
