Keep the file named exactly as it was downloaded (usually Ksw-Q-Userdebug_OS_vXXX-ota.zip ). Do unzip or extract the file.

Turn on your car's ignition to power up the Android head unit.

By running a Userdebug OS, you can mod your head unit (install Viper4Android, change boot animations, modify system files, run shell scripts). The downside? It is less stable and harder to find official support for.

Ensure your flash drive is formatted to FAT32 rather than exFAT or NTFS. Additionally, confirm that the file is named correctly without accidental double extensions like .zip.zip .

Download the specific target firmware package (e.g., Ksw-Q-Userdebug_OS_vXXXX-ota.zip ).
