How to enter flash mode

To acess fastboot, you can use any of:

Turn off the device, then hold Power button and Vol- simultaneously until the device powers on
With ADB access, run adb reboot bootloader

Installation

Using pmbootstrap (downstream kernel)

Follow Installation/Using pmbootstrap. When asked for the device's vendor/codename, select xiaomi as the vendor and spes as the codename.

To flash the image to the device:

Enter flashing mode (see #How to enter flash mode)
Run pmbootstrap export, then use aik-unpack to unpack the boot.img, replace the header version from 0 to 3, run <aik-repack> then flash the newly made image with fastboot flash boot yourimage.img
Run pmbootstrap flasher flash_rootfs

Mainline

Right now, the mainline kernel is not available for download, as is the U-Boot source for this device. I am working on stabilizing the build enough for it to be ready for actual development of more features. For the current source, or if you want to help, please ping @SCOS100 on Telegram.
