My 19007/4631 is constantly rebooting

My System has been running fine for a couple weeks now. All of sudden I noticed it started rebooting (green light would flash every 6 seconds).

I can put it into into DFU mode fine. I was able to drag and drop the Meshtastic_nRF52_factory_erase_v3_S140_7.3.0.uf2

Then after reboot I go into DFU mode again and drag and drop the
firmware-rak4631-2.5.11.8e2a3e5.uf2

after which it starts rebooting again.

Any assistance would be appreciated.

Logs I was able to capture:

Ok I think I have it working. The original erase utility in the firmware zip Meshtastic_nRF52_factory_erase_v3_S140_7.3.0.uf2 never prompted me in the terminal to erase NVRAM (not sure if that’s the correct term for where the firmware is written).
I found this utility ‘nrf_erase2.uf2’ which when dropped in in DFU mode brings up a prompt in the serial terminal to perform an erase, after that everything seems to work ok, sort of. I think the the minor issues I see are with the Meshtastic firmware so no reason to mention them on this forum.

I would like to get some clarification on the differences between Meshtastic_nRF52_factory_erase_v3_S140_7.3.0.uf2 and ‘nrf_erase2.uf2’ . I am guessing ‘nrf_erase2.uf2’ is from RAK or the chip maker and Meshtastic_nRF52_factory_erase_v3_S140_7.3.0.uf2 is from Meshtastic. Is that correct?

Also none of this really explains why my device crashed and I had to erase and reinstall. I guess that’s the nature of software/firmware.

Reminds me of the old joke (30 years old really doesn’t apply any more): If Microsoft built cars you would have to pull over every 100 miles and reboot it.
