Install Android 6.0.1 Marshmallow on your Xperia Z via CyanogenMod 13

Time to update your Xperia Z to Android 6.0.1 Marshmallow now. This isn’t an official update, but an update that will happen via CyanogenMod 13. Sony has dropped the Xperia Z from the Android Marshmallow league. Xperia Z2 and the devices which came afterwards will be getting Android Marshmallow. The original Xperia Z and its fellows do not happen to be lucky enough. Sony did a great job by updating the device to Android 5.1.1 Lollipop, now we have to continue the journey with the help of custom ROMs. When it comes to custom ROMs, CyanogenMod is probably the best choice as it happens to be the most widely used aftermarket Android firmware.xperia-z-white

The ROM that landed in for Xperia Z is based on CyanogenMod 13 as mentioned above. The only thing that doesn’t work in this ROM at the moment is the camera, but I wonder if any third party application will make it work as well. Rest of the stuff like RIL and other features are found to be working pretty well. The ROM is in its alpha stages so there are great chances of bugs. We recommend Android power users to go ahead and flash this ROM or if you’re a newbie, you’ve to read the instructions being very careful. We will go through some precautions and then begin with the flashing process.

Time to jump up to the method in order to flash the Android 6.0.1 Marshmallow on your Sony Xperia Z via CyanogenMod 13 custom ROM.

Some precautions

  1. This guide is intended for Xperia Z only. Do not try this on any other device.
  2. Charge your Xperia Z up to 50% to avoid any power issues during the flashing process.
  3. Flash a custom recovery on your Xperia Z.
  4. Backup everything including your contacts, call logs, sms messages and bookmarks. Also create a Nandroid backup.
  5. Follow this guide to the letter to avoid a mishap.

Disclaimer:The methods involved in flashing custom recoveries, ROMs and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is SONY in our case.

    Do I unlock my device to install the ROM?

    • @swordhuang:disqus If you’re going to use the recovery we linked above, you probably won’t need to unlock the bootloader.

  • @swordhuang:disqus If you unlocked bootloader and your device isn’t booting up, you will need to flash a stock firmware and then install custom recovery on it. Can you please tell me what was the Android version on your device before you flashed this ROM?
