How to Root Sony Xperia Z2 C6543 on 23.0.1.A.0.167 with Locked Bootloader

Since the arrival of 23.0.1.A.0.167 update for Sony Xperia Z2, there isn’t any simple or typical way to root the device while running this Firmware. A lot has tried in the past, but somehow there methods were only for their own device, doesn’t work on others and even if they does, some of their apps stop working or the rooting methods does something that forces the users to go back to Stock device again. However, XDA member rafaelbelo, has arrived with another rooting method, quite unique and different, no need for a locked bootloader or any different tool or any of the complex adb commands, all you need is the Flashtool and a little knowledge about the Flashtool.

The process, put simply, goes on like this, first you will downgrade the device, root it on the downgraded version using towelroot, update the fimrware to the same version again and thus the latest firmware will be reveled, update it and your device will maintain the root along with the latest firmware running, without any need of an un-locked bootloader. Without further ado, let us continue to the Back-up links along with the Step-by-Step tutorial.

Early Preparations:

• This is only for Xperia Z2 C6543!
• Battery should be charged at least over 60%
• Backup SMS Messages
• Backup Call Logs
• Backup Contacts
• Backup Media – Copy your files manually to your PC or Laptop.
• Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content.
• Backup Nandroid – If CWM  or TWRP installed previously, otherwise skip this step and perform this at the end of flashing
