Those seems to be related with the "Overt-the-Air" (OTA) firmware.
If you don't need that OTA, maybe you can flash other firmware versions.

- Wed Apr 08, 2015 1:51 pm #13895 I managed to brick an ESP-07 by touching the module when it was waking from sleep. Firmware flash with esptool seemed to work, but re-flashing with nodemcu did not help.

The Fix:
I downloaded Ai thinker firmware, flashed it and it booted ok. Last step was to flash witn nodemcu again. This worked.

I think there may be some settings which were corrupt and which are somehow initialized to default values by ai firmware but not by nodemcu.
