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.

Ok guys i need some help, i unlocked the bootloader on mine Z3 with the official method by sony, flashed TWRP recovery and rooted it.
But after i did all that i heard about the DRM on the camera, is there a way to relock it and return to factory state?

No, you have lost the DRM keys forever.
You can relock using flashtool, but it will not restore your DRM keys
I got an update on my Xperia M2(d2305) to 4.4.4. I rooted my phone when it was 4.4.2. When I try to update it, it shows an error where it says (Sony update engine failure error 2003). I unroot my phones using the factory data reset but still with the same error. When I checked the bootloader it still say YES. .how do i lock back?

You got an update on your Xperia M2(d2305) to 4.4.4.So you didnt unlock the bootloader. Right?
First when you root your phone that makes a file name su in your system.Factory data doesnt change system folders.So you have still root access.
All you need to do is;
-install supersu
-Get into setings
-Click unroot botton That remove your root access.
i am not sure but if you instaled xposed you may need to remove it.You can find it in firmware options.
(Just in case: to relock the bootloader Connect your phone (into flash mode) to Flashtool and click the "BLU" button )
Good Luck
@XlseS
Did you try to relock it with Flashtool? There was option for that i did it on my Tipo.

Press BLU icon, connect your phone in Flash mode, press Relock.
Good Luck.

Device does not boot after I did that.
Are you on stock rom?

JUST DOWNLOAD FLASHTOOL AND YOU'RE DONE!: HERE
1 boot into fastboot
2 head over ur computa and click relock, easy enough ? :silly:
I had an update to 4.4.2 via PC Companion, so files are all there.
If I reflash my phone, will the TA partition get reflashed too? In other words, will it get back my DRM keys?
There is method with TA script to backup and restore TA, but if I have backup of original ROM that came with my phone, so I'm asking will it do the job, because I have TA.img without md5sum.
Another reason is this one: http://www.xda-developers.com/restore-lost-functionality-on-your-unlocked-xperia-device-part-two/
Camera seems to get loss of functionality with removal of DRM keys.
EDIT: The answer is: nope. TA partition must be restored first.
Hello to everyone
I've a question and a idea.
Can I root my Xperia Z3 with this tool? http://forum.xda-developers.com/crossdevice-dev/sony/giefroot-rooting-tool-cve-2014-4322-t3011598
If It's possibile i think to downgrande (with the first firmware founded on this thread) my phone to Firmware < October 2014 (kernel and system) , after root with this tool, save the DRM Keys, upgrade to the last firmware, unlock the bootloader and remake the root and at last restore the DRM Keys It's possibile?

Welcome to the party
Yes its possible, but why would you unlock the bootloader just to restore the DRM keys straight afterwards? That relocks your bootloader and will prevent custom kernels from booting
Bacause I'm interested to the last stock firmware so, If I root the phone white this tools and after upgrade to the last stock firmware the root will be deleted or not?

Ok, I see what you mean. Yes you will lose root if you upgrade to the latest firmware. However, to get root on an unlocked bootloader you need a custom kernel (even one based on stock is custom) so as soon as you restore the DRM keys you will no longer be able to boot.
The best bet is to
downgrade
root
Install recovery
flash a pre-rooted firmware of the which ever version you want. You can create this using PRFCreator_v0.8 (Just google it) and it will take about 7 minutes to make it.

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 guys, so i just bought a Z5 Dual E6683 online yesterday and it turns out to be a Commercial/review model with 32.0.A.5.19 firmware installed, and I'm planning to root it to restore my Titanium Backup.
There're 3 things that I want to ask,
1. Is it possible to root it and upgrade to MM but with DRM still intact?
2. If so then do I need to flash another ftf 1st or change kernel or anything?
3. If I flash another Lollipop ftf, does it erase my current DRM or no?
Nah you have to unlock BL to get Z5 rooted. You can try the DRM backup tools though.
Patched kernel is enough just for root
If you flash official FTF you won't lose DRM(you only lose it by unlocking BL), however, I don't think it is possible to flash back to LP

You mean there's no going back to Lollipop once you patch the kernel and upgrade to MM?
But to patch the kernel I need to unlock BL right?
So, in conclusion I need to flash official LL ftf 1st (any build (?)), then backup DRM and unlock the BL, patch the kernel, and finally upgrade to MM?
And do I need to backup my current firmware (32.0.A.5.19) ?

You have to flash a Lollipop firm, then use this http://forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597 . Backup your DRM and then you are ready to open the bootloader, and flash a rom or root or do what you want.
You are on right firmware to root and proceed.
1. Is it possible to root it and upgrade to MM but with DRM still intact?
Ans. Yes, use this tool to back drm first from http://forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597 and then unlock bootloader and then download any MM firmware and flash. Then you need patched kernel to root your device from here http://forum.xda-developers.com/xpe...ot-automatic-repack-stock-kernel-dm-t3301605.
or I have already made for E6683 for the latest MM firmware here http://forum.xda-developers.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605
you can use as you wish.
2. If so then do I need to flash another ftf 1st or change kernel or anything?
Ans. as i said above.
3. If I flash another Lollipop ftf, does it erase my current DRM or no?
Ans. flashing doesn't erase anything but bootloader unlocking does. So answer is NO.
