  Hello @Support Dasaita ,

   

  I noticed there are 2 versions of the new QCM6125 G13 firmware. What is the difference between the two?

  Android 13 Update

  G13 Version: Ensure your unit is QCM6125 Android 13

  • Build: zst27_sc138_13_V1(20251030)

  • Build: zst27_sc138_13_V2(20251031)

  Thanks!

  J

  @J L 

  Hello.
  For your information, V1 and V2 are mainly used to differentiate the core board versions.
  Please go Settings > About Machine, 
  then provide the following picture: Build Number; MCU version.
  So that we can learn your version information.

  @Support Dasaita Thank you for the G13-V2:   But how about the MCU ? 

  Question is there a big difference beween G13-V2: vs G13-V1: main software only not the unit it self?

  And can you ruin your G13 if you install the wrong one?   Why I ask cant find the info on it!

  The zst27_sc138_13_V2 will help with my mic issue or that's a MCU issue.

  I also have massive problems with the steering wheel control not working to.
