How to enter flash mode

  • Entering fastboot: hold Volume Down + Power buttons until fastboot mode is displayed on the screen.
  • Entering recovery: hold Volume Up + Power buttons. The default is Mi Recovery. TWRP is needed for installation, which can be obtained here

Installation

To flash this device, the boot partition have to be flashed by fastboot:

$ pmbootstrap export
$ fastboot flash:raw boot /tmp/postmarketOS-export/boot.img-xiaomi-dior

However, rootfs could be flash by pmbootstrap normally:

$ pmbootstrap flasher flash_rootfs

And its system partition is quite small (800mb), to flash a large distribution (e.g. xfce4), you have to:

1. Split the boot and root partitions (hint: you can use pmbootstrap install --split instead of losetup tricks):


sudo losetup /dev/loop0 /tmp/postmarketOS-export/xiaomi-dior.img
sudo dd if=/dev/loop0p1 of=boot_partition.img
sudo dd if=/dev/loop0p2 of=root_partition.img
sudo losetup -d /dev/loop0

2. Flash the boot partition to system partition:

$ fastboot flash system boot_partition.img

3. Use the netcat method to flash to user partition:

Additional info

This original implementation of framebuffer device do not support framebuffer console and X-Windows, we patched all missing pieces such that it works. So xfce4 and FbKeyboard works now.

However, due to lacking of DRM driver, all drm related UI are not workings.
