Android Head Units

Before making any changes, make sure you have a backup of your original file.

1. Use a USB drive with FAT32 formatted partition
2. On the root of the USB drive, create a folder called OEM
3. Copy your file into OEM folder, so that it’s accessible under /OEM/zxw_factory_config.xml location
4. Plug in the USB drive into Head Unit (if you have two USB connectors, use the one without CarPlay label)
5. You can now either start/restart the Head Unit to load the file automatically. You should see a toast message indicating that settings were applied.
6. Alternatively, go to Factory settings, “Profile Import” and tap on “Update” button to load the file manually.

1. Download suitable firmware OTA update (check Discord or forums for links)
2. Compare the file signatures with values from Updates page (if available) to make sure file is not corrupted
3. Copy the ZIP archive directly to the root of the USB drive
4. Plug in the USB drive into Head Unit (if you have two USB connectors, use the one without CarPlay label)

The factory_config.xml file is a device/vendor specific configuration file that gets shipped with your Head Unit. Before you make any changes, please make a backup of the original file, so that you can always revert to it.

1. Download ADB from Android SDK Platform Tools
2. Create a Wi-Fi hotspot on your phone
3. Connect Head Unit and your laptop to that Wi-Fi hotspot
4. Connect to the Head Unit with ADB

   adb connect IP:PORT
   

5. Pull the file into your laptop

   adb pull /mnt/vendor/persist/OEM/zxw_factory_config.xml
   

6. Disconnect
