#73307 Can you point out where it recommends to ground GPIO0?

That would normally be a bad idea as that pin is sensed during boot and if it is 0 puts it in flash mode.

That was the whole idea to flash new repeater firmware from:

#73321 Grounding GPIO-0 is only done to get the ESP8266 into the flash programming mode. To run the application code that input must be high during the reset of the chip.

Maybe I just don't understand what you mean by instability. I have only found the ESP8266 to be unstable when it was not supplied proper power.

#73322 Can you describe the flashing process for me? I was under the impression gpio0 was held low during the entire process but you seem to be suggesting otherwise.
