i have gs8000 with 1.0.9 firmware but i dont know back up my firmware to share for everyone .... i try with autoexec.ash in topic about gs1000 and can not back up ....
My GS8000 also has 1.0.9 it was posted by a member here. GS8000 1.0.9
I have not noticed any difference personally.
My GPS stopped working, but that was before i updated i believe and is more a hardware
issue.
My camera still gets warm, but has not overheated yet as it had before, but i have also not used it for long periods of time after recently finding out that it had a card issues and not a camera issue that kept it from recording.
