Nodemcu Esp8266 V2 flashing

[Fuselx]

Hi,

i have a problem with my Nodemcu Esp8266 V2.
Espeasy is working fine, but i want to try an other firmware. The problem is, it won´t let me flash it to a "factory reset" state.
I connect GPIO 0 (D3) with GND, restart the device and use the "FlashESP8266.exe" to select another espeasy firmware. After confirming the settings the ESP8266 starts blinking and after 1min it´s finished.
But nothing changed, it is the same as before.

I also tried to reset it with the "Nodemcu Firmware Programmer" - same result.

What is it that i´m doing wrong?

What devices/sensors do you have connected to the ESP?
I have seen that some devices may interfere with getting the ESP into flash mode.
However, I've been always successful with these by holding the flash button pressed during the entire flash period.
So holding the flash, also press reset shortly, then start flashing while holding the flash button.

Hi,

thanks !
"holding the flash button pressed during the entire flash period" did it. I overreaded this step in the tutorial.

best regards
