I bricked my GDR E350.
What i made before:
1.Update to ver 2.70 with webupdater. After this device worked normal. I made 2-3 manual reboot to make sure that it will start again. No problems.
2. I added safety cameras in GPI format.
After this device worked well, but after reboot it won't load again. Only green lamp work.
I can't connetct this to computer anymore/
So i think problem in GPI file. It have to be way to hard reset this unit but I didn't find any solutions yet.

It is Garmin OS. But problem that i have no idea how to make this in preboot mode. I guess it must be combination of 4 buttons. It doesn't have sensor screen
As far as I remember those GDR devices are not based on traditional GarminOS and GarminCure3 will not work for sure.
Can you show me some firmware files? I was rather talking about GDR 20/30. This one looks quite different.

I don't have access to original one. This one was installed with webupdater
And it worked. So i think this one compatible with TW deviceCode:Please Login or Register to see the links

It's not traditional GarminOS for sure. It's some very specialized Real Time Operating System. And it's not even similar to GDR 35 which I used to explore in detail.
I think there should be a possibility to execute firmware upgrade from the SD card. If it works, you can try installing the original firmware. Or maybe flash a cure firmware which doesn't rad GPI.
Yes. This is the way how this device get update. Webupdater copy it on memory card. After restart It install firmware somewhere on internal memory and delete it from memory card. Very similar with GoPro. No way to access in internal memory
