my FTDI was in 3.3V mode. Make sure you do too!</p>

<p>Once that was sorted it was time to do a quick <code>flash_erase</code> and a <code>flash_write</code> of the new Micropython build for the 8266. Things should be smooth sailing from here. Let’s just do a quick <code>erase_flash</code></p>

<p>Off to the googler (well, the duck, duck, go-er) to figure out what the issue is here. Most of what I find is people flashing Micropython on the SONOFF with no problems. Technically, I did it with no problem according to the flash verification.
What I’m specifically looking for is “SONOFF Micropython no REPL”. That lead me to this solution.</p>

<p>He’s also posted a fairly detailed write up on why you shouldn’t waste your time with the SONOFF modules as they seem to all be unreliable both in runtime and connectivity. I won’t let that discourage me as I’m not using it for anything mission
