Xiaomi M365 Firmware Downgrade from 1.4.3, 1.4.2 or 1.4.1 to 1.3.8 DYoC/CFW/RollerPlausch/etc
PLEASE FOLLOW THE STEPS DESCRIBED IN THE VIDEO EXACTLY IN THAT ORDER, OTHERWISE YOU MIGHT BRICK YOUR SCOOTER!!!
Xiaomi Mijia M365 is an excellent electric scooter straight out of the box, but you might want to improve upon that and I sure wanted to improve mine :). You might want to get extra speed or extra mileage, you might want to tweak the regenerative braking or other parameters of the scooter. To do any of these things you need to flash your scooter with custom firmware, but this is not as simple as it was in the past so this video might be able to help you.
If your current firmware version is 1.4.1, 1.4.2 or 1.4.3 and you want to install a custom firmware based on 1.3.8 on your Xiaomi Mijia M365 electric scooter, then you will have to install an app called M365_Patched on your Android phone (link to the apk at the bottom of this page: https://m365.botox.bz/), flash the firmware file named DRV140ENC.bin (can be downloaded from here https://1drv.ms/u/s!Aqs8w_gChI2mhtgJrRE4qdxZpcEXvA), then create a custom firmware using https://m365.botox.bz/ and flash it to the scooter.
Feel free to ask any question in the comments section and, if I know the answer, I'll reply as soon as I can.
