Xiaomi Poco X3 (karna) 

Make a backup now, as your device will be wiped.

Before you proceed

Any recovery should work but TWRP is recommended

Downloading the needed files and tools

Please download the belowed needed files and tools:

Device preparation

  • A USB 2.0 port/hub with an actual USB 2.0 controller is recommended (Using fastboot on a USB 3.0 port may cause errors with some Xiaomi devices)
  • Save your APN (Android)
    • The Access Point Name or APN can be found in the Settings menu of Android
    • Take a piece of paper or a text editor, and write down everything that you see on that screen
    • These are likely to include a URL (e. g., internet.carrier.net), a username, and possibly a password
  • Unlock the bootloader (using Computer)
  • Boot into recovery (Computer)
    • Boot TWRP by running fastboot boot twrp.img
  • Wipe the device (using TWRP)
    • Go to the Wipe menu
    • Select Advanced wipe
    • Tick the boxes called Dalvik / ART cache, Cache, System, Data
    • Swipe to Wipe
    • Go back to the previous menu
    • Choose Format data and type yes
    • Go back to the main menu and select Reboot
    • Choose Bootloader
    • Boot TWRP again by running fastboot boot twrp.img
  • Copy the files to the device (Computer)
    • When TWRP is booted, open the device’s Internal storage from your computer
    • Copy all of the files you downloaded to this folder

Droidian installation

  • Install the boot image
    • Install the file called boot.img as an Image to the Boot partition using TWRP
    • Alternatively, you can enter fastboot mode and fastboot flash boot boot.img
  • Install the DTBO image
    • Install the file called dtbo.img as an Image to the dtbo partition using TWRP
    • Alternatively, you can enter fastboot mode and run command fastboot flash dtbo dtbo.img
  • Install the vbmeta image
    • Install the file called vbmeta.img as an Image to the vbmeta partition using TWRP
    • Alternatively, you can enter fastboot mode and fastboot flash vbmeta vbmeta.img
  • Install recovery
    • Install the file called twrp.img as an Image to the Recovery partition using TWRP
  • Install Droidian rootfs
    • Install the file called droidian-OFFICIAL-phosh-phone-rootfs-api29-arm64-arm64_YYYYMMDD.zip as a Zip file
    • sideload is broken on this version of TWRP so file must be pushed to data and flashed from recovery itself.
    • devtools is already included in nightly builds.

Finalizing the installation

  • Extract adaptation-surya-script.zip and install adaptation via pushing it to the phone and running install.sh
    • adb push adaptation-surya-script /tmp then adb shell and cd /tmp/adaptation-surya-script && chmod +x install.sh && ./install.sh
  • Boot your device
    • Go to the Reboot menu and choose System
    • TWRP might complain that there is no OS installed, but that’s fine
    • You should be greeted with the lock screen, the default password is 1234

Congratulations, if everything went well you should be booted into Droidian.

Notes

Default password

The default password is 1234.

APN

Mobile data needs an APN to be set up from Settings -> Mobile Network -> Acess Point Names.

Broken mobile data after calls

Data connection might break after recieving and making calls. Switch it off and on from Settings -> Mobile Network to fix it. Be careful to not turn off the mobile modem or a device restart might be required.

Out of storage

By default when flashing Droidian it allocates 8GB of storage to the system. This might not be enough and luckily you can allocate more storage with ADB by running (while in recovery): adb shell e2fsck -fy /data/rootfs.img and adb shell resize2fs -f /data/rootfs.img xG where x is the amount of GB to allocate (eg: 50G for 50 GB).

Booting times

Booting times are currently within 5-10 minutes.

Audio

Currently speaker does not work but bluetooth earbuds/earphones work.

Camera

Camera works on Waydroid but not on the system itself. So it is usable but every time user wants to use it they have to start Waydroid.

SSH access

Flashing the devtools zip enables SSH over USB. To use it, connect your phone to your computer and type ssh droidian@10.15.19.82, the password is 1234 (on Windows, you may need PuTTY)

Applications

You can find a list of mobile-friendly Linux applications at LinuxPhoneApps
