WiFi

For some reason, enabling 802.11n WiFi makes the connection slow and unreliable and causes most downloads to stall. As a workaround, 802.11n support has been disabled. Somebody also had this issue on a Xiaomi Redmi 5 (xiaomi-rosy).

Flashing

EDL mode can be entered by holding the Volume Up and Volume Down keys while plugging in or turning on the phone.

Fastboot mode can be entered by holding the Volume Down key while plugging in or turning on (but not rebooting!) the phone.

Unfortunately, there is no publicly available EDL loader, and the bootloader is locked. However, these restrictions can be temporarily bypassed using a secret fastboot oem sudo command. To boot custom software, you also need to flash a custom vbmeta image and avb_custom_key, otherwise the device will refuse to boot.

The stock bootloader write-protects most partitions when booting from the boot partition, so it is recommended to use the recovery partition for booting postmarketOS.

Installation

TODO. For now, use the weeknd-toolbox (linked below) to install lk2nd to the recovery partition and then use pmbootstrap flasher commands for flashing.
