So, did anyone find out how to flash firmware for G55W/LD500/etc from PC or from TF card after failed update? It lays dead for several months already and if there is no way to make it alive maybe it's time to throw it away... So if anyone found a way to flash it, please share your method.
There really is only one way .. Put the firmware on the SD card , insert the card and power the cam ...
The cam will read the card , finding the firmware it will then update ...
Failure to follow procedure may mean a spectacular fail .. ( For example a fully charged battery or non interrupted external power )
If you screw it up , there is usually only one way to recover and that's through the factory .. ( same way original firmware is installed )
So if you have screwed the pooch , or stuffed up your firmware .. Then the cam may simply no longer have functioning firmware , in which case the cam wont read whats on the SD card and wont update ...
In which case , you have a bag full of spare parts ...
Updating firmware is easy , but what ever you do , never ever interrupt the process ...
And if you have a cam that works as it should , why would you ? ( If its not broke , dont fix it )
It might be possible to flash VIA PC-USB , but you might need a FLASH PROGRAM ( like what the factory uses ) ...
Perhaps similar to what is used to update firmware on Radio Control Transmitters ..
Also a USB flash cable with the correct interface chip ...
This might be something only the manufacturer knows ... And they may not wish to give away proprietary software ...
I don't think the dashcam community is quite as well organized as the RC community when it comes to firmware PLAY ... ( Or even the Nikon community or PC community etc )
