Complete Factory Reset following

[ROBERT Marlan]

I was adding a gpy device to pybytes and had trouble with it connecting online via wifi. So I deleted the device from pybytes and reflashed it to 1.20.2.r4. The device is working and shows the REPL but two issues - I no longer can see a heartbeat LED flash and the LTE no longer connects with code verified with a different unit. I have reflashed twice with no change. Everything was working fine prior to registering it on pybytes.

When flashing I Enable Smartbytes / Smartconfig support and erase the FatFS along with resetting the CONFIG and NVS partition. How do I completely reset this back to the original factory settings? Below is the console outout. Thanks for your help.

Since posting I have figured out both issues.

For some reason, Pybytes modified my LTE modem to LR6.xx for NB-IoT from LR5.xx is for CAT-M1. My carrier requires CAT-M1.

The heartbeat issue was corrected by using pycom.heartbeat_on_boot(True). BUT - this is the default setting- so I don't understand why this was not reset when I reloaded all firmware with the Pycom utility.

My continuing question is how do you perform a Full factory reset if the reload of firmware does not seem to do this. Is there a list of all default settings so this could be manually done if necessary?
