The MatePad 10.4, depending on the model, uses a Kirin 710A or 820 chipset. HiSilicon Kirin processors are notoriously difficult to develop for because Huawei has not fully released their source code and hardware documentation under standard open-source licenses. Consequently, there are no official builds of LineageOS, Pixel Experience, or Paranoid Android for this tablet. XDA Developers forums, the traditional hub for such projects, have only scattered threads discussing potential GSI (Generic System Image) installations. A GSI is a pure, vendor-agnostic Android build from the Android Open Source Project (AOSP). In theory, any Project Treble-compatible device can run a GSI. The MatePad 10.4 does support Treble, but users who have attempted GSI flashes report a litany of broken features: Wi-Fi and Bluetooth failures, unresponsive auto-rotate, broken audio routing, and, most critically, the inability to use the M-Pencil or keyboard accessories.
