I have installed CE 9.2.8 od SD card which use with box Mecool KIII Pro,
Everthing works well, but sometimes after switching off device and try power on, it is not working, jus black screen (no Mecool logo), no booting.
I tried to make hard reset (press button 10 sec) and try without SD card it is not working,
After many attempt I successed, box works well, reboot works well and only if I switch off device then not possible to have correct boot.
Anybody had experience with this issue.
