How to Update the Sony Xperia ZR to Lollipop

Pin It

The Xperia ZR is one of the most forgotten flagship devices of the Xperia line up second only to the Xperia Ion. Smaller brother to the Xperia Z, and without the added water resistivity features, the Xperia ZR was doomed from the start. But for those souls who did grab one of them, we have a little salvation for you guys! Sony may have forgotten all about you but XDA hasn’t! And that’s why we have Lollipop for you guys, brought to you by CyanogenMod 12.


Pre requisites

  • Your Sony Xperia ZR must be rooted with it’s boot loader unlocked.
  • You must have a custom recovery installed, like TWRP or CWM.
  • Your phone must be charged over 80%.
  • Some common sense and ability to follow instructions.


With that done, let’s get this show on the road. There are two ways to do this and we will highlight both ways in here.

Via Recovery

Step 1

Boot into recovery mode. To do so, power off your phone. Switch it back on and the time when you see your phone’s LED notification light turn Pink (or changes to any other color) you’ll have to start pressing either the Volume UP or Volume Down key a couple of times to make your phone boot into recovery mode

Step 2

Backup your current ROM from your custom recovery.

Step 3

Do a complete wipe, data and cache.

Step 4

Navigate to your SD Card and select the ROM zip file. Flash the ROM. (For your convenience we advise that you keep the zip file at the root of your SD card)

Step 5

If you’re so inclined, flash the GAPPs package.

Step 6

Reboot. The first boot will take longer than others so don’t panic.

Via Fastboot

Step 1

Install fastboot and ADB.

Step 2

fastboot flash boot boot.img
fastboot flash system system.img

Step 3

Follow Step 5 from above from here on out.

Root : From CM 12 root permissions can be enable by going into settings>developer settings.

Congratulations you have CM 12 nightlies running on your Droid Bionic. If you are the sort who updates daily, please remember to take a backup before flashing the latest nightly either from recovery or via OTA.
