Background
If normal brushing doesn't work, here will provide a way to force the device into brushing mode for forced brushing. This will theoretically fix all firmware issues on the ESPHome side.
How-TO
Briefly, the whole process is divided into:
- Disconnect the power supply and open the 1MS housing with a tool such as a spoon.
- Plug the 1MS into a USB-C cable and the other end into your computer.
- Open the Recovery Tool webpage on your computer using Chrome: https://tool.screek.io/factory_tool/1m_1ms/
- On the circuit board of the 1MS, press the BOOT button and hold it, then quickly press RST and release it, this puts it into DFU mode.
- Use the online recovery tool to rewrite the factory firmware on it.
- Re-power up the 1MS and using the online recovery tool, check the device logs to see if it is working properly.
After that you can use the online tool to wire the 1MS.
