MCU - problem after update
I was looking for a solution to my problem here but I couldn't find it, so I'm asking for help

I bought a Mitsubishi ASX in which the previous owner installed the JOYING Sofia 3gr 1GB/16ROM radio from 2018.
The radio did not work well, the navigation and the Google play store and other applications did not work.
After update(FYT SOFIA 1024x600) all apps work but screen shows "UI AND MCU DOES NOT MATCH! "
After 30-40 minutes the screen starts flickering every 5-6 seconds. After reboot it's ok for another 30-40 minutes and flickers again. How to solve this problem?
