Hi
Im trying to upgrade my mcu because i having some trouble with bluetooth/wifi connection that appear randombly. Basicly It start to looping with the connection without connecting.
Back to my problem: i've ask dasaita trough AliExpress for a new mcu and a new os to install, they give me the mcu "3.80" and HA3_rk3399_10.0_ota(20220412).
Unzip those and put It in an usb pen, i had to change name to the mcu file from hmcu.img to dmcu.img .
So far i was only able to upgrade the os but everytime It give me an error about the mcu i will also inserti my version on.
Hope you Will Be able to help me
