Nothing after ok?

try M552 S-1 followed byM552 S0 it should give you the output from the ESP8266 bootloader at least

It looks like it is hanging on the ~ld. something is broken

Ah, I might have done M552 S0 before M997 come to think of it.

Anyways, it shows the ESP is trying to boot into mode 3,7 instead of 3,6 - I don't recall the specifics around that issue but smarter people than me should have all the necessary information now at least.

I don't see anybody like that around at the moment. Will have to wait for DC to have a say.

Only things I can think of to try in the meantime:

redownload the wifi server bin file, check that the downloaded size matches, rename it and try flashing again
Use these commands to try and clear the saved list of SSIDs and then try starting it again.

M552 S0			; Disable network module
G4 S5			; wait 5 seconds
M588 S"*"			; Clear all saved wifi networks

After doing all that, I get this "Error: M588: Failed to reset the WiFi module to factory settings"

Thanks for trying guys! Hopefully, DC has some good news. Fingers crossed.

yeah, that was kinda expected as it seems the wifi module isn't starting its firmware properly.

descember puts you just shy of the 6 months warranty doesn't it? if you've got some hot air soldering tools, or people with tools nearby its quite doable to replace the wifi module, or depending on your location https://forum.duet3d.com/topic/13875/community-repairs?_=1593191305483

Lets see what DC says before you take the torch to it.

Alright <sadly putting torch away>.

I'm sorry, we see this type of problem reported occasionally, and we don't know the cause. The only solution we know of is to replace the WiFi module. Please ask your supplier to replace your Duet under warranty.
