Installation

Install TWRP (3.2.3 and 3.3.1 are available). Format the System partition to prepare for the postmarketOS image. Either install from a recovery zip directly in TWRP, or use pmbootstrap flasher as usual.

Status

Using the LineageOS kernel (which is derived from Lenovo's open-sourced kernel), we can boot to a graphical display with USB networking. If CONFIG_USB_G_ANDROID is not set, it seems that there are a lot of errors regarding charging when connected via USB, and the boot doesn't get through to init. The touchscreen is detected, but the driver gets disabled in libinput due to a kernel bug.
