tuya-convert: Tried flashing (flash3) but didn't work, tried undoing, now device unresponsive - Tonbux switch

I’m kinda freaking out. I successfully flashed the middleware firmware, got this info:

READ FLASH: http://10.42.42.42/get?read=HEX-ADDRESS
ChipID: 258c75
MAC: 3C:71:BF:25:8C:75
SdkVersion: 1.5.3(aec24ac9)
BootVersion: 4
BootMode: 1
FlashMode: 1M QIO @ 40MHz
FlashChipId: 1440c8
FlashChipRealSize: 1048576
FlashChipSize: 1048576
FlashChipMode: 0
system_upgrade_userbin_check: user2 0x81000

Then I did curl http://10.42.42.42/flash3. It said Device should flash http://10.42.42.1/files/thirdparty.bin and restart. But the device didn’t restart, it just stayed connected to the vtrust-flash and the “sonoff-xx” AP never came up.

I waited an hour, and then did curl http://10.42.42.42/undo to try again. It said it would undo and restart, and the device disconnected from vtrust-flash but never turned back on. Now I can’t get it to turn on at all.

@onebyside @AlphaDE – Got the first one flashed as well using the serial ports with the Raspberry Pi Zero. Nice! Both have Tasmota now. I realized the first failure never managed to backup the factory firmware. Perhaps some sort of Wi-Fi connection issue with the vtrust-flash AP on the Pi Zero the first time around.
