I hope someone can help me with this. I just tried to upgrade de firmware to the latest version in my Fastrack Supreme 20 wm20452. It has the 6.63 firmware version so I followed the process through the migration package exactly how its explained on the wavecom´s web page. I upload the file dwl for the q2687 wireless cpu from the migration kit and the one from the firmware release 7.4.
The problem is that the modem doesnt register to the network anymore. The LED doesnt blink anymore, its always on. The response to the AT+CREG? command its (0,2). When I power cycle the modem I get this wind outputs:
Anyone knows what could be the problem? What should I do to correct it? The firmware version was the right for my modem or I should had use another file? Will my modem work again?
I tried the firmware upgrade to use the M2M studio that I just downloaded and develop faster but now I can go any further until my modem works again.
Thanks for reading my post, hope you can help me.
