Step By Step Guide 

Install Android 6.0 Marshmallow On Xperia Z3

Step 1. Download the Marshmallow ROM files from above. That is, system.img, userdata.img and boot.img. And also the Gapps file, to install Google Apps after installing the ROM.

Step 2. Create a folder called z3update and transfer the system.img, boot.img and userdata.img to this folder.

Step 3. Connect your Xperia Z3 to PC. Transfer the Gapps file to it. Remember the file’s location. And disconnect the device from PC now.

Step 4. Boot your Xperia Z3 into bootloader mode. If you are rooted, you can use Quick Boot app from play store. To manually boot into bootloader mode, do this:

  • Power off the device. Wait for 4-5 seconds after screen goes off.
  • Press and hold Volume Up button and then connect the device to PC using USB cable. You will enter fastboot mode. Screen won’t show fastboot written on it, btw.

Step 5. Now, open command window in the z3update folder, in which you have the system.img file with other two files. For this:

  1. Open that z3update folder and then left click on empty white space in the folder.
  2. Now, while holding shift key, right click on empty white space to get a pop-up as shown below.
  3. Now choose Open command window here option from that.

You will see a command window open up, with location directed to z3update folder.

Step 6. Run the following commands to install the Marshmallow update on Xperia Z3.

fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot reboot

Wait for Xperia Z3 to finish booting up, it may take some time. Once it does, check the Settings > About device. You should have Marshmallow under Android version. Congos!

→ Btw, if you face force close on apps a lot, or device lagging too much, then do a factory reset using TWRP recovery to solve that problem.

Step 7. You don’t have Google Apps right now. You need to flash the Gapps file from recovery mode. Make sure you have TWRP installed, and have transferred the Gapps file to your Xperia Z3 too.

  1. Boot your Xperia Z3 into recovery mode. If you are rooted, you can use Quick Boot app from play store.
  2. [Optional] Once in TWRP, create a backup of your device. Tap on Backup, and then select all the partitions for back. Now do the swipe action at bottom to start creating a backup for emergency cases. This backup is really a lifesaver!
  3. Now, install the Gapps file. On TWRP’s home screen, tap on Install, and then locate the Gapps file and tap on it. Then do the Swipe action at bottom to begin flashing the update.
  4. When it’s done, tap on Reboot system button to restart the device.

Done!!! You have successfully Downloaded & Installed Android 6.0 Marshmallow On Xperia Z3
