GS1000 wrong/correct firmware

[Dandan]

I load probably wrong firmware to my GS1000. Record to SD card work correctly, but menu on the display is unreadable. On motherboard is version PS1000AB-GPS-V30, 2012-11-05.
What is the correct firmware for this dashcam?
What is the solution of my problem?
Enclose a photo.

Thank for help.
