Samsung Galaxy S9+ (Exynos) (star2lte) 

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

  • 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 (Computer)
  • Wipe the device (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 Recovery
  • 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 (TWRP)

  • Install the boot image
    • Install the file called boot-star2lte.img as an Image to the Boot partition using TWRP
  • Install Droidian rootfs
    • Install the file called droidian-OFFICIAL-phosh-phone-rootfs-api29-arm64-nightly_YYYYMMDD.zip as a Zip file
    • Alternatively, you can enter ADB sideload mode and run adb sideload droidian-OFFICIAL-phosh-phone-rootfs-api29-arm64-nightly_YYYYMMDD.zip
    • devtools is already included in nightly builds.

Finalizing the installation

  • Extract adaptation-exynos9810-script.zip and install adaptation via pushing it to the phone and running install.sh
    • adb push adaptation-exynos9810-script /tmp then adb shell and cd /tmp/adaptation-exynos9810-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 memory 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).

Status

Droidian GSIs are experimental! Bugs and missing features are expected.

Audio

Currently audio does not work and only the microphone works.

Calls

Because of the audio issue user cannot hear audio in calls either.

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
