SailfishOS Installation on Xperia XZ

Preparation

Download the following files from sx.ix5.org:

  • 2019-03-14-system.img (save as system.img)
  • hybris-boot.img
  • sfe-f8331-3.0.1.11-heroic.tar.bz2

Then download these additional files:

Install fastboot on your computer. Instructions can be found at developer.android.com. An alternative installer can be found at xda: Minimal ADB and Fastboot.

For accessing fastboot mode on the device, see Accessing special Modes.

Install required Recovery

Install AdrianDC’s TWRP recovery via:

fastboot flash recovery twrp-3.2.1-20171219-boot-kagura.img

Install Software Binaries

Unzip the downloaded file so that you get SW_binaries_for_Xperia_Android_8.1.6.4_r1_v16_tone.img. Flash the image via fastboot to the oem partition:

fastboot flash oem SW_binaries_for_Xperia_Android_8.1.6.4_r1_v16_tone.img

Flashing Android Parts

Flash hybris-boot.img via fastboot:

fastboot flash boot hybris-boot.img

Then flash the system image via fastboot as well:

fastboot flash system system.img

Flashing Sailfish Parts

Push sfe-f8331-3.0.1.11-heroic.tar.bz2 to /sdcard/ on the device.

Then run these commands manually in the device’s recovery, e.g. TWRP:

rm -rf /data/.stowaways/sailfishos/
mkdir -p /data/.stowaways/sailfishos
tar --numeric-owner \
    -xvjf /sdcard/sfe-f8331-3.0.1.11-heroic.tar.bz2 \
    -C /data/.stowaways/sailfishos
rm /sdcard/sfe-f8331-3.0.1.11-heroic.tar.bz2

Reboot and you should be done.

Note about going back to Pie ROMs

Since this SailfishOS port is based on Android Oreo, when you want to go back to a Pie ROM after flashing SailfishOs, you need to either flash the stock firmware for the dsp partition via FlashTool/Emma or manually re-label the files in /dsp to adsprpcd_file.

The exact reasons and procedure are described in DSP File Relabeling for SODP.
