I have a 2019 M365 that was running firmware 1.5.6, BLE 091, BMS 126. I installed the CFW using the instructions given in https://www.youtube.com/watch?v=nlhz8XJFMYg. Essentially downgrade BLE to 072 and then using https://m365.botox.bz to create a CFW. I only changed the max speed limit.
Everything worked great, have to say its a great vid. I just anted to check if I can change back to stock by upgrading the firmware via the Mi Home app. I connect fine and it offers the update. However, when the update starts it says "updating board firmware" and then just fails after a few moments.
Has anyone seen this issue? Has anyone managed to return to stock this way after doing a CFW?
Thanks a lot. Amazing work guys!
