  • Reset if stuck: hold volume up and power button till the phone shakes

Non-standard notes

The Xperia Z does not have a recovery partition, so flashing PostmarketOS erases any recovery you have installed. Instructions across the internet for reinstalling a custom recovery are almost all incorrect.

To install a custom recovery on the Xperia Z:

  • put the device in fastboot mode
  • run fastboot flash boot recovery.img (replace recovery.img with the filename of your recovery of choice)

What works

  • charging
  • network through USB
  • telnet in initramfs
  • ssh
  • adjusting the led, torch and the lcd backlight
  • display
    • Weston
    • Xwayland
  • touchscreen

What does not work

  • Splash screens

What has not been tested

  • Bluetooth
  • 3G
  • Sound
  • Phone calls
  • SD card
  • Wifi

Issues

  • Launching Weston is delayed by 135 seconds to let udev settle down

Other information

  • When red leds are flashing, offsets are wrong
  • LineageOS boot.img is far larger because the recovery is inside it
  • It should be possible to run The Mainline Kernel on the device. At least there is a dts file already in the 4.14 kernel: arch/arm/boot/dts/qcom-apq8064-sony-xperia-yuga.dts
