#7914 We're having a bit of an outbreak of gremlins too, but from a 10000 feet perspective I feel that there are likely to be more than one cause, and each situation may well invoke a different combination of these.

For example, problems in the middle of a flash aren't likely to be due to the firmware itself, nor the schematic. In this case it might be power supply trouble or noise on the serial lines - trying to keep them short and not going via breadboard helps here.

So in general, be careful to recheck everything over and over again! Many times after sweating over problems I have to leave them alone for a few hours and sometimes that can cast magic all on it's own, at least it seems. :D

#7925 I just did a few more tests.

Flashed back on the AT firmware from here https://drive.google.com/folderview?id= ... ptbzg#list
ESP8266_AT_V00180902_04 (0018000902-AI03)_unconfirm version.bin
completed at least 10 power cycles without one failing.

I then flashed the frankenstein firmware with the same result. 10+ power cycles all good.
