JY-UQS80N4G-GT update and Zlink fixes

[maxizozo]

Hello, I would like to know if there is an update for my unit JY-UQS80N4G-GT



Zlink is not working (Zlink service unavailable) and I want to know if other ROMs are available because I need Android Auto





Is it possible to replace the actual ROM (new interface Snapdragon 625 CPU) with an old ROM and old interface? (Maybe a ROM for UIS7862 units?)

I want to remove the black screen when reverse (No video signal) because I dont have camera

I only need beep sound for front and rear sensor (because I hear no sound when doing reverse approaching to other cars)



Please help me to fix this

Thanks a lot
