Building and installing

There are multiple installation methods for your Xiaomi A1. They all rely on flashing one or more partitions on your device.


All installation methods can lead to data loss.

Flashing a partition will erase everything on the partition. Additionally, the common backups methods, e.g. TWRP, will not backup the userdata partition, which may be the installation target.

Make backups.

Using Fastboot

This will produce a folder with a flashing script, and the partition images for your Xiaomi A1.

$ nix-build --argstr device xiaomi-tissot -A build.android-fastboot-images

Alternatively, you can build a specific partition image:

$ nix-build --argstr device xiaomi-tissot -A build.android-bootimg
$ nix-build --argstr device xiaomi-tissot -A build.rootfs

The device will need to be booted in its bootloader, or fastboot, mode.

The boot images can be installed using the following command, assuming the android-fastboot-images output was used.

$ result/flash-critical.sh

If you have a system image (system.img) built, you can use fastboot to flash it to the device. Note that it might be too big to fit over the system partition. In such case, it can be flashed on the userdata partition.

$ fastboot flash userdata system.img

Using a flashable zip

An alternative installation method is to use a flashable zip. The flashable zip can be built for your Xiaomi A1 using one of the following commands:

$ nix-build --argstr device xiaomi-tissot -A build.android-flashable-bootimg
$ nix-build --argstr device xiaomi-tissot -A build.android-flashable-system
$ nix-build --argstr device xiaomi-tissot -A build.android-flashable-zip

The first two will flash only a specific partition. The last one contains the partitions of the two previous one.

The zip can either be copied to the device and selected in a compatible Android recovery, or sent to the device through adb sideload.

$ adb sideload /nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-flashable-xiaomi-tissot-boot.zip

By default it will flash to the system partition. Some configurations may change this to flash to the userdata partition. In that case, no warning is given before flashing.
