Root Xperia M4 Aqua and Install Custom Recovery

As the name suggests, the Xperia M4 Aqua is a waterproof Android device and comes with some good enough specifications. The smartphone has a 5-inch display with 720p HD display and is powered by 1GHz processor alongside 2GB RAM. Like most of the Sony devices, it comes with an amazing 13-megapixel rear camera. To make things even better, we can root Xperia M4 Aqua and flash TWRP recovery that will help you install custom packages on your device.

First, you will need to flash the TWRP image onto your device using the usual fastboot method. Once you install a custom recovery, you can then flash the SuperSU package in order to gain root access on your device. Before we begin, you need an unlocked bootloader on your Xperia device. We already have the guide available for that purpose. Moreover, you need to set up ADB and fastboot environment on your PC for this method to work successfully. If you are new to this process, then we will help you successfully install a custom recovery and finally root your device.

During this procedure, you will need to mount the partitions manually. There is no GUI as Sony has not been able to provide sources to build it. Moreover, there is external SD card support. Hence, you will need to mount the partitions manually issuing some commands in ADB shell. It’s recommended that you read the tutorial first and make a wise decision. So let’s begin with the tutorial.

fastboot devices

• Now flash the custom recovery. Use the following command for that.

fastboot flash recovery recovery.img

• The custom recovery will now be installed on your device. Don’t boot into TWRP just yet.

Now the TWRP recovery is installed. However, you will need to mount the partitions manually. There is no GUI as Sony has not been able to provide sources to build it. Moreover, there is no external SD card support. Hence, this remains the only option so far. So let’s continue with the mount procedure.

• Connect your cable, make sure you have ADB and drivers installed.
• It’s better to use Linux OS for this purpose. However, the command prompt should work just fine. In your terminal or dos window issue the following commands:

adb shell

• You will get a prompt like ~ #
• Now issue the following three commands:

mount -w /dev/block/platform/7824900.sdhci/by-name/system /system
mount -w /dev/block/platform/7824900.sdhci/by-name/userdata /data
mount -w /dev/block/platform/7824900.sdhci/by-name/cache /cache

• Now you will have the partitions mounted.  You can now proceed to flash your zip files. As we don’t have external SD card support, we will use the sideload method. Issue the following command:

twrp sideload

• ADB shell will exit. Now we are ready to install the SuperSU zip file and gain root access. Issue the following code:

adb sideload <path_to_zip>

• Path to zip on your computer without the < > For instance, if you have placed SuperSU at C:\Downloads\SuperSU.zip then type:

adb sideload C:\Downloads\SuperSU.zip

• Once the operation completes, issue the following command:

adb reboot

• Now unplug your device and use the SuperSU application to grant root access.

Make a complete backup from the recovery once installed. You can boot into TWRP by turning your device off and then press and hold volume down and power keys at the same time.
