How to flash AOSP Android M Developer Preview

Before flashing, testers are required to manually compile the AOSP ROM. To do this, Sony has put up a list of pointers, instructions and a detailed guide; these can be accessed by navigating to Sony's dedicated micro-site.

After creating test images, as explained above, using Sony's developer kits, follow the steps mentioned below to flash the image onto your Xperia smartphone. Do remember that IBTimes UK will not be held liable for any damage to the device during or post installation of the AOSP ROM:

  • Before flashing, ensure that your handset is unlocked, using Sony's unlock boot loader.
  • Connect your Xperia smartphone to your computer in Fastboot mode, by pressing volume up while inserting the USB cable. When the device is in Fastboot mode, the LED on the device will be lit blue.
  • On your computer: Flash the boot, system and user data images by entering the following commands in a terminal window:
    fastboot flash boot out/target/product//boot.img
    fastboot flash system out/target/product//system.img
    fastboot flash userdata out/target/product//userdata.img.
  • Do remember that it is not always mandatory to re-flash user data each time you flash your smartphones. If your handsets do not boot due to the new software displaying incompatibility with the previous data, only then re-flash the user data.
  • Disconnect your Xperia handset from the PC, and verify the device is running the new AOSP.
