hey Thommo . i forgot to mention it's only for 4.3 only
I've taken care of it now, thanks
RaviDsi Before you do anything or downgrade your software back to jelly bean, i'd strongly advice you to repair the current software in your phone to see if it fixes you problem.
Kitkat 4.4.4 is really smooth for the Z series.
Here is how to do that
Download PC Companion and install it. Do not connect your phone until you're asked to do so by PC Companion
Start Support Zone > Start Phone/ Tablet Software update > select Repair my Phone / Tablet > Follow the on screen instructions it shows
If after reinstalling the software you still face the problem then let me know and i will help you with downgrading.

I_Mithun The method to root has already been given above. Click on the spoiler below "root xperia SP" and follow the method to root with towelroot apk. It merely takes a minute to root.

I have just obtained a Sony Xperia M4 Aqua. Owing to the internal storage space issues, I am wanting to root my phone to get rid of some bloatware.
I am looking for suggestions as to how to go about rooting this model, as well as any suggestions as to which specific apps etc I may want to delete in order to free up more space, as I can't even update my apps now, let alone download new ones. Have already moved what apps I can over to my SD Card.
I have attempted using the towelroot method, but it says that my phone is not supported.
Also, any suggestions as to how I can check that it has actually been rooted will be appreciated.
I am a complete noob to the world of rooting, so kindly keep that in mind when responding.

To root Xperia M4 Aqua, follow this guide and let me know how it goes for you.
Regarding removing apps, you will have to be really carefull.
First you should download an app that allows you to remove system apps. ( I use Root Explorer )
Using such app, go to
1) System > app> Select the app you want to remove and delete it.
2) System > priv-app > select the app and delete.
Now, what all you want to delete depends on what you use or not.
You can remove google apps like " Drive, Play music, Google Movies" etc. By removing them, you will free up system space. You could always download them from google play store but this time it would only take up half the space in your phone as it's not present in the system.
I've removed about 45 apps from my phone ( Xperia Z) and I think I should have had made a list of them to help others. Unfortunately.
Please ask me or any other person before removing the apps you want. You could list the apps you think you want to remove and I will try my best to help decide what to delete and what not to delete.
Oh and yeah, most important of all, backup everything important on your computer :smileysmileywink:
