How to root my Xperia M4? And how to use external memory as internal memory?

[InfusionIsMe]

Hey guys, my phone has literally only got 400MB of internal memory left and I wanted to do something about it.

Apparently in order for me to use my external memory (micro-sd) card, I'll need to root my Android device first.

How do I root my Xperia M4 Aqua - 8GB? I have checked and it does indeed have a unlocked bootloader (don't know what that is but apparently that's good) and how can I root it so it doesn't get bricked? I don't want to use any customized ROM or anything as I heard that you can get bricked via that. I just want to root it, nothing else.

And after rooting, how do I use my micro-sd card as internal memory on the phone? Thanks!

Hello!
Follow this guide to get ROOT; http://forum.xda-developers.com/m4-aqua/general/tut-blu-twrp-root-xperia-m4-aqua-t3238962

I use link2sd to link apps to SD card.
You have to make two partitions on The sd card.
Google link2sd and you will find plenty of guides

Good luck

Another thing worth mentioning is that Android Marshmallow has support for merging your SD card and internal memory into one, meaning that the SD card will literally become an extension of the internal memory. However, you'd have to wait for the Marshmallow update for your Xperia M4 aqua for that..which will most likely arrive early next year.
