Not sure to understand what you mean but if your question is to know if I fill in the "Post Flash Action" of your tool the answer is no.
First I just want my sonoff to boot to be sure everything is OK and I need its MAC adress to add it to my network.

OK I tried few times and now no more errors on flash but my sonoff never boot, no led on, no wifi hotspot... I will try all *1024.bin files just in case...

Thank you for this explanation.

For Tasmota it's only in DOUT so I thank this could fix the thing but with espeasy how can I do that ?

@TD-er Thank you for your reply.

So the version is ESP8266EX with memory XTX PN25F08 so 1M but I also test esp8265 just to try and no luck...
Can you tell me more about the build with DOUT marking ?

Hi So I got the sonoff sv but I am unable to flash it with espeasy... No response after Flash... I tried Tasmota and it works so my sonoff is OK.
I tried espeasy mega 20180302 1M in dev normal and test with successful flash but my sonoff never start after that...

Someone could help me please ?
