Root and Install TWRP on Xperia Z2 Android Marshmallow 23.5.A.0.575

Right after the Android 6.0.1 Marshmallow 23.5.A.0.570 update, Sony rolled out another update for the Xperia Z2 and Xperia Z3 series which moved the build number to 23.5.A.0.575. The new update brought stability and some bugs were fixed. If you have updated your device, or you’re planning to update it to the latest Marshmallow firmware while you happen to be an Android power user, you must keep in mind that flashing the stock firmware wipes off the root access, custom recover and other tweaks from your device. If your Xperia Z2 was rooted earlier and now you’ve lost root access, you may want to root it once again to modify the device running on Marshmallow firmware. Rooting Android 6.0.1 Marshmallow directly isn’t possible, but you sure can root it using a little different method that is discussed here.

We are set to go through the instructions to install a pre-rooted Android 6.0.1 Marshmallow 23.5.A.0.575 on our beloved Xperia Z2 D6503 and D6502. The guide illustrates how you can flash the pre-rooted firmware to gain root access and TWRP recovery. Before getting onto the method, we will learn some precautions to make sure that nothing goes wrong during all this process.

Note: If your device is already running on .264 firmware and is rooted with a recovery installed on it, you may skip the first two steps and jump straight to the method to flash the Marshmallow pre-rooted .zip file.
