The Android 9 system firmware can be updated via USB but the software can't be upgraded to Android 10 due to different hardware. The system firmware update is only necessary if there seems to be problems with the unit functioning properly.Hi Ray,
For all of us having the unit running Android 9, any possibility to upgrade for the latest firmware. I remember at the time one of the selling points for Android 9 units were the fact it could be upgraded via USB stick.
