1. Garmin DriveSmart 50LM, Firmware 540, HWID 2267.
2. Tryed to update unlocked firmware, but RGN tool doesn't show the HWID so I wrote it by myself.
3. After update device pops up message: "Software is missing!" and cannot load.
4. It cannot be seen from the computer as device anymore.
5. Tryed all the procedures with GarminCure3 but the device cannot boot and immediately shows that Software Missing.
6 I don't have any backup files.

I hope someone can help, please!
Thanks in advance!
