Tips and questions relating to the GPS modules from SFE

I have LS20031 and I tried to upgrade firmware using DIYDrones custom firmware ver. 1.6: http://code.google.com/p/ardupilot/wiki/MediaTek.
After I uploaded their firmware successfully, the red led on board is always turned on, and I can't communicate with Arduino using GPS_MTK or TinyGPS library; MiniGPS_1.4 can't fix position.

Output in serial monitor:
Code: Select all
$GPGGA,000016.800,,,,,0,0,,,M,,M,,*47
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPRMC,000016.800,V,,,,,0.00,0.00,060180,,,N*4D

I'd like to roll back firmware. Does anybody have the original firmware?

I did the same thing thinking it would work since it's supposed to be the MT3329 MTK chipset.

Anyone have any advice. My symptoms are the the same as above.
