Ubuntu Touch on the Samsung Galaxy A51 (SM-A515F) with pre-installed Docker

An unofficial port of Ubuntu Touch to the Galaxy A51 (a51, Exynos 9611), built on Halium 13 against the stock Android 13 vendor partition (A515FXXU8HWI1) - the only vendor this bootloader accepts, since it is fused to revision 8 and Samsung blocks the downgrade.

Working: display and touch, the Lomiri shell, apps, the on-screen keyboard, Wi-Fi, USB networking, Docker. Not working: telephony, Bluetooth, audio, GPS, fingerprint.

Layout
