extremely difficult
Installing a custom ROM on the Huawei MatePad 10.4 is and generally discouraged due to Huawei’s permanent closure of its official bootloader unlocking service in 2018 . Without an unlocked bootloader, you cannot flash custom recoveries like TWRP or alternative operating systems. 1. The Bootloader Obstacle

1. AOSP / GSI (Generic System Images)
Because device-specific development is thin on the ground, many users turn to GSI ROMs (Project Treble). This allows you to run a generic version of Android (like Pixel Experience or LineageOS) on the device.
The Huawei MatePad 10.4, powered by a Kirin 710A / 820 chipset (depending on variant), lacks official custom ROM support due to Huawei’s locked bootloaders and discontinued unlock code service. This paper investigates the technical obstacles, including ARM TrustZone, HiSilicon’s proprietary boot flow, and lack of kernel source transparency. We explore potential workarounds (e.g., using project Treble GSI) and conclude that while generic system images may boot, full hardware support (Wi-Fi, audio, accelerometer) is unlikely without Huawei’s proprietary blobs.
