Installation
- Follow the Installation guide
$ pmbootstrap install
$ pmbootstrap flasher flash_lk2nd
$ pmbootstrap flasher flash_rootfs
Note: pmbootstrap will install the lk2nd bootloader. |
How to enter flash mode
- Stock Fastboot: Power on the device with both Power and Volume Down buttons
- lk2nd Fastboot: Power on the device. After it vibrates, hold Volume Down
Note: Pressing the keys too early will cause the stock bootloader to handle the key combination. You will end up in the wrong Fastboot interface. |
- Recovery: Power on the device with both Power and Volume Up buttons
OEM unlock
First make sure to enable USB debugging [1] and OEM unlock in Android. Then with device powered off, hold down Volume Down and Power buttons simultaneously for a few seconds, until Fastboot Mode screen appears. Plug in USB cable and do:
$ fastboot oem unlock
Wipes
Wipes work very strangely. Fastboot says that the wipes were successfully completed, but the partitions are not cleared. Therefore, the only way out is to make wipes from twrp or use formatting.
$ fastboot format:ext4 boot_a
$ fastboot format:ext4 boot_b
$ fastboot format:ext4 system_a
$ fastboot format:ext4 system_b
$ fastboot format:ext4 userdata
Dual booting
We can use the a/b markup feature for dual booting. In this case, we will have the kernel in the boot_a (or boot_b) section and the rootfs will be located in the same system_a (or system_b) slot. The opposite slot will use Android.
To find out the active slot, run in fastboot:
$ fastboot getvar current-slot
To switch a slot, run:
$ fastboot set_active a / b
E.g., if your Android ROM uses slot a, flash lk2nd to slot b:
$ pmbootstrap flasher flash_lk2nd --partition boot_b
The system partition severely limits the available space. So, you can install the rootfs to an SD card.

Downstream
There is an alternative device port using the downstream kernel, xiaomi-tissot-downstream
. It can be selected by entering the name in pmbootstrap init
.
Note: The downstream kernel is entirely unmaintained and only intended for testing features for the mainline kernel. |
