I read about it. Seems that the operation damages the bootloader.

It was a question - is it so for sure ?
Or only at my "straight hands" ?

I guess that RST is used during the flashing process. Maybe it should be pulled up additionally

If RST and GPIO16 (WAKE) are connected, and to make

B4X:

pinWAKE.Initialize(16, pinWAKE.MODE_INPUT_PULLUP)    'RST is pulled up

the flashing is working, but ... no start after re-flashing , until the manual reset.

Actually, if RST and GPIO16 (WAKE) pins are connected for DeepSleep - mostly i cannot re-flash it . But sometimes - it's reflashed - why not stable ?
Who investigated - any solution to use togerther OTA and deepsleep (with connected pins) ?

SOLVED: RST and GPIO16 (WAKE) pins must be connected not by short circuit (just wire), but via small resistor, say 470 Ohm.
