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). (Citation needed)
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: Review |
With these instructions, you can have KaiOS and postmarketOS dual boot, with pmOS on a microSD card. This guide assumes you have flashed the postmarketOS image into a microSD and inserted it into the device. (This will NOT work if you had installed the weeknd toolbox previously.)
- Clone the weeknd-toolbox repo
- Do
touch Image.gz-dtbto avoid building Linux - Install
arm-none-eabi-gcc(On Debian and Ubuntu:apt install gcc-arm-none-eabi) - In the weeknd-toolbox directory do
TOOLCHAIN_PREFIX=arm-none-eabi- ./build.sh - Enter fastboot mode
fastboot oem sudofastboot flash avb_custom_key pkmd.binfastboot flash vbmeta vbmeta.imgfastboot flash recovery lk2nd.img- Hold Volume Up key
fastboot reboot- Flash the boot image:
fastboot flash recovery boot.img - Now to boot pmOS from microSD, reboot while holding the Volume Up key, release the key as soon as the warning appears and again hold it as soon as it disappears.
