Factory Reset for R412M

Without a solution for my previous topic, I’m wondering if anyone knows a method of resetting the R412M to factory defaults?


Hi Darkwater,

I was told that Jan was in contact with you.
To reset the device, use AT&F0 & ATZ0.

See page 121 & 122.


Thanks for your reply - I have tried those commands, and they do not reset ALL the settings on the device. For example the previously set APN is still set, and the PSM and eDRX are still toggled off.

Additionally, whatever erroneous setting that is prevent me from finding and connecting to my LTE-M provider was still in place.

However, I did find the solution to the problem. For whatever reason, automatic selection of MNO Profile was no longer working - Manually trying different MNO Profiles fixed the issue.
