Sonoff TH10 Recovery Conundrum
Posted: 26 Jun 2021, 07:56
For several weeks now I have been attempting to recover a Sonoff TH10 that I haven't used for over a year. I am not sure what I loaded onto the Sonoff, I think it was ESP Easy or it could have been Tasmota?
When powering on the device either via 240 volts or via the serial adapter, no lights appear on the Sonoff TH10 and no matter what I do, the TH10 doesn't respond to any software... esptool.py, Tasmotizer, or esptool. The serial adapter was used previously to flash the Sonoff Th10 to whichever firmware I loaded onto it, so I know it worked at one stage. I even crossed the RX/TX wires, in case that was causing the issue. And also held down the button on the TH10 prior to supplying power via USB. So for some reason the serial appears to not be working?
I've tried the Tasmota recovery options here... https://tasmota.github.io/docs/Device-Recovery/ and various ESPEasy recovery processes but with no luck. But there was something interesting I found... when you hold down the button on the TH10 and apply USB power, and continue to hold the TH10 button, after 50 to 60 seconds a WiFi network appears... named Sonoff1_3 and appears to be encrypted because it requires a password/key to gain access.
Despite trying every password I could remember, I couldn't gain access to the WiFi... so... with the serial not working, and the recovery options not enabling serial access. I figure gaining access via WiFi might be the only way I am going to be able to reset the TH10. There is possibly something I am missing, which is why I am posting here... in the past I've found the people on this community to be really knowledgeable.
So perhaps there's someone that knows some thing I've missed or haven't tried?
