To Reproduce
Sonoff Basic is configured to use relay to power a 5V power supply. GPIO14 is configured as WS2812. Have ~ 70 LEDs configured.

On fresh flashing, works as expected. After about 24 hours, device appears to revert to config in config_override.h and loses it's WS2812 config. Reapplying the module configuration develops the following error in the logs after several self-reboots:

23:04:08 MQT: home/DVES_A86D05/INFO3 = {"RestartReason":"Fatal exception:0 flag:2 (EXCEPTION) epc1:0x401069a9 epc2:0x00000000 epc3:0x00000000 excvaddr:0x00000000 depc:0x00000000"}

Expected behavior
Not crash & maintain configuration

Additional context
Only been fairly recently (since 6.2 I think) that this has happened. Confirmed against several Sonoff Basic devices.

No bug this is a feature. Reverts device to standards. It recognizes watchdog resets and trys to
bring it in stable condition to have a chance to do maintenaice.
So your compiled version has problems (faulty) or the connected stuff draws to much current

Please, try to erase all flash and flash again but using the provided precompiled bins with latest Tasmota v6.4. Thanks.

I too encountered a similar problem.
After some reboots due to power surges, the device returned to the 'Sonoff basic' state instead of staying on 'Sonoff Generic', losing the switch/pin configuration.
All other configurations (MQTT, for example) have remained unchanged.
Is it possible to change the firmware (which file?) To force the default state of the configuration and of the pins?

The whole idea of getting a stable environment after several quick reboots relies on resetting reboot causes using a step down model. After a reboot within 10 seconds a step is taken from this process.

Disabling this feature defeats the self-restoring functionality of the device.

If you don't want it just remove lines 2658 until 2680 from file sonoff.ino.

Thank you @arendst for reply!
The concept is clear and correct.

I see the lines on GpioInit function to comment for prevent the reset of the pin configuration.

P.S.: Thank you so much for reply Teo: this is my first post on github platform, and I want to thank the whole development team for the fantastic work you are doing.

Hi,

Is it possible that with WifiConfig set to 0 and the Wifi Access Point going down, this bootloop detection would be triggered and everything reset to Sonoff Basic?
