Flashing a custom ROM on the Sony Xperia M4 Aqua smartphone presents the ultimate risk-reward scenario. ROMs are often what people keep away from due to their ability to brick your device should you do it wrong. Though cases of complete bricks are rare, they are possible. On the other hand, flashing a custom ROM is one of the most fun times you could have and offers you the greatest change on your device that you can do to get away from what the Android developers, phone manufacturers and phone carriers want to give you.

Anyone into the device modification scene would be well aware what the word ‘debloat’ means so this custom ROM hardly needs explaining. For everyone else, you should know that a debloated ROM means that it comes to you without any of the system apps slowing it down and taking away from the battery life. These system apps are usually installed by your phone carrier networks or even the device manufacturer, which is, in this case, Sony.

You can also choose to install the Quick Boot complication from the Google Play Store if you don’t like using the hardware button combination.)
  6. Tap on the Backup button and take the complete backup of your Aqua’s data with the NANDroidd feature.
  7. Choose the Wipe button from the main recovery menu after you backed up the data first and it will wipe your device and apply a factory reset.
  8. Select the Install option from the recovery menu and browse the SD card for the debloated ROM file.

In conclusion, that’s how to install the debloated custom ROM on the Sony Xperia M4 Aqua smartphone. You should find the Xperia M4 Aqua device is now tons faster once you reboot the handset back in normal mode and start using the new debloated ROM on your device.
