tobias.waldvogel's method is the easiest way to achieve it imo. His guide covers it all from A to Z (How to back up your DRM keys, unlock the bootloader, patch the stock kernel and flash it back on your device, get a working TWRP Recovery, root Android with SuperSU, re-apply the DRM keys to restore functionalities, etc.)
Follow the steps and you'll get it to work. You won't need anything else, everything you need to have/know (files, tools, etc.) can be found in the first post of that thread

[Question] Unlock bootloader risks

Hi all!
I have my Xperia M2 with the latest firmware: 18.6.A.0.182.
I want to root it, and install a custom recovery, and i know how to do all of this through this forum. But I need to unloock my bootloader.
What's the problem?
If you go here: (i can not post links, the developer sony / unlockbootloader) and warns you:
Important note! In order to unlock your Xperia™ M2 you need to be on software version 18.3.C.0.37. Also beware that booting this device the first time after unlocking the boot loader may take a long time.

I don't know why this...
Searching in google, the people recomends to use flashtool to unlock the bootloader.
What will happen if i intend to unlock it and something goes wrong? I don't know how to solve a soft-brick withouth an unlocked bootloader.
Thanks for your help.
Hey, first do it the official sony way flashtools doesn't work for many including me when i unlocked my bootloader. http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Second if anything goes wrong, just reflash your firmware (jellybean, kitkat, lollipop whatever) through flashtools and it will be back to stock.
Unlocking your bootloader there is not much which can go wrong.
Btw, you will lose your DRM keys. 2 of them i think for buying stuff through ps store.
Also if you run into problems post here we'll help.
Now I have root with KingRoot. If I make a backup of TA partition i can restore DRM keys when I like it, no?
And the magic question for me is: How I flash original firmwares if the bootloader is locked? I only need locate the right FTF and with flashtool is enought?
Thank you!

Yes you can restore your DRM keys backup if you want in the future.
And if you want to flash a FTF on locked bootloader you can use Flashtool by Androxyde or Xperia Companion.
Ok, thank you all, I'll try to backup DRM keys and unlook the bootloader and I'll post the results!

Hi there,
I know this post is related to another user but I wish to relock my bootloader for another reason and was wondering if you could help me please?
I have TA backups, and what I am trying to do is to restore the DRM keys via the RootKernel tool; however, everytime I flash it via FlashTool, I can never figure out if it worked or not?
Could you tell me if there's a way to check if the DRM keys have been restored on an UNLOCKED bootloader please?
Also, can you tell me how to relock the bootloader, as well as restoring the original TA so everything works fine again please??
Thank you for your help
==========================================================================
Edit: I've found out how to relock the bootloader and restore TA, but I still don't quite know how to check if the keys are installed when on UB?
got the same problem as OP. anyone know how to get camera work with lock BL and stock FW.???

The same problem here, I've re-locked the phone and installed the stock Nougat ROM using Sony's PC companion, so no TA backup and after that every time I open the camera, it says ''Error: the camera may be in use by another application. please close the other application and try again.'' It's also the same for developmental Marshmallow ROM that I've installed by EMMA and even with the boot-loader unlocked the camera quality is really poor and doesn't save the picture it takes. So have I messed up the DRM security keys as part of boot-loader ? How can I fix this ??
I found this in Sony's developer site:
''Once you have unlocked the boot loader, you will not be able to revert the device back to a locked or original state or restore the DRM security keys.''

May I borrow your TA back up and DRM keys for my F8331 ?
Dont use someone else's TA Partition. It ain't going to work.
Why don't you simple re-open your BL and flash a Stock ROM ? What is the benefit of re-locking if you lost your TA Partition ?
Picture quality is the same as stock unlocked if you flash androplus kernel

WARNING!
using another one's ta partition in your phone will hard brick it. Each xperia has it's unique ta as an identification for the chip. Do not ever think about that.

Comming back to MM with Root

Hey Guys , this is the last time i bother you with my threads i swear
I have prepared all the pre-required to root my Z5 (wich was runnig MM and now runnig LP 32.0.A.152)
I have succesfully backed up my TA partition with Iovyroot v.03 (Thank you very much for the link josephnero !)
I have my Bootloader unlocking code from Sony Official website .
My Bootloader is not Unlocked Yet, I do a last Security Check before this step .
I would like to know if When i will have unlocked my BL and Restored My TA and DRM if i could come back to MM and Keep My Root and DRM ?
I saw somewhere a few soft i don't understand , like AndroplusKernel or Xperifirm , even when reading the tutorial From A to Z i can't undertand the purpose of those soft and how to use it .
Can someone explain me what the goal of those soft and how it works please ?
Please don't be rude with me i'm a NOOB and i don't want to Kill my phone
It don't bother me to reflash a Stock MM rom if i must do it
The Final goal i want to reach is , My Z5 E6653 Running MM ( Stock or not i don't care ) Root with DRM restored
Thanks in advance for Everyone helping me !

First backup your files.
Then unlock bootloader(this will erase you files)
Then flash 32.2.A.5.11 using flashtool, then download patched kernel(i will send it using private messages).
Then flash your backed up TA patrition, and then flash supersu using twrp, and you are good to go.
Bro i honestly dont know How to thank you !
You took the time to help me and i'm pretty grateful,
I'm on my phone and my Z5 is now rooted and fully functional (it runs the last MM Firmware)
Btw there something pretty strange, i dont know How But i loose no functions using DRM like bravia engine the strangest thing is that i didn't retore my TA or my DRM Key i didn't applied DRM patch too !
I'm so happy But i honestly don't know How i managed to do that ?
I tried Track ID it works, Bravia enhance it works i don't know How

Flash FTF via flashtools and wipe everything it's pretty straightfoward, you can get it here. Download, open xperifirm, flash.
To restore drmkeys you need to have a backup before you unlocked your bootloader otherwise your DRM keys are lost forever and you will have to flash either a kernel or
drm fix.
