The right way to get back DRM keys if u unlock the bootloader for custom kernel

WHAT YOU WILL ONLY NEED:
- Windows 7/8 and Flashtool.
- .77 (KitKat) Firmware
- .690 Firmware
- DRM LP fix in your SD card (DRM Function Restoration for Xperia Lolipop V2)
- Androplus LP ADV Kernel (I used Z3_ADV_stock_LP_v2)
- THIS GUIDE WILL RESTORE THE DRM KEYS FOR THE SONY FEATURES TO WORK AGAIN(CAMERA X-REALITY ETC...)
NOT UR ORIGINAL KEYS,
Be sure to have the LP DRM FIX in your SD card prior to flashing stuff.
- If your Bootloader is UNLOCKED, LOCK IT (Relock).
- Don't turn it on. If somehow it turns on, hard turn off it by holding VOL UP and POWER until it vibrates 3 times.
- Flash the .77 FTF (Flashtool).
You're back to .77 (KitKat)
- Let it boot till the language selection screen.
- Power it off.
Now you will be going to Lollipop with old TA features, plus a custom kernel so you can use Recovery.
- UNLOCK your bootloader now and:
- Flash the .690 FTF checking the "TA" box. Which means you are EXCLUDING the TA partition from .690 in order to keep the .77's. This is where the magic lies!
- Right now, you are already on Lollipop.
- Right after flashing it, flash the Androplus ADV LP kernelV2 (get it from the Androplus kernel site). That means you are going to get Recovery functions.
- Right after flashing the kernel, access the Recovery screen (holding VOL UP/DOWN when the Z3's led is purple) and FLASH the DRM Fix which should be in your SD card.

I didn't backed up earlier, Already lost my DRM, can I restore it still :$ ?

Same question here. It is not clear from the first post whether this restores DRM after losing it.

I'm guessing it will work without original backups as there is no part of the tutorial where you restore from a back up. Looks more like a return to stock from any state.
Not that I'm an expert, last Sony I had was a Z1.

I'am not sure if I got this right, please correct me if I'm wrong:
So using this method I will end up with a custom kernel with custom recovery and still got all Sony DRM features that are usually lost when unlocking the bootloader. How exactly does this work? My guess is that the TA partition is not deleted directly by unlocking the bootloader but when booting into Android by the CredentialManagerService. And this hack simply prevents the CredentialManagerService from deleting the TA partition. Am I right?
Edit: I think I got it wrong. This will only restore the Camer and Display features, but not Miracast. Am I right?

Yes i think, i didn't test miracast

I did this procedure and it seems to have worked. I had some trouble with flashing when the bl was locked. I had to keep it unlocked the whole time. I had to flash several times due to some error messages in the flash tool.
After doing this can I flash a different LP customization (the US one) while keeping the TA information or do I have to downgrade to KK first, then go back to LP, doing this whole process again?

Thanks. Do I only have to flash Lollipop, excluding TA in Flashtool, then the DRM restore zip? Or do I have to go back to KitKat each time?

what if i directly flash the zip from cm12's recovery maintaining the bootloader locked? (lazyness over 9000)

Anyone tested going from .77 KK to 23.1.A.0.726 ? There's no .690 for D5833

Waiting for confirmation that the AndroPlus kernel will wok on .726.

Really? On which devices? How exactly?
And I have a question about OP.
Can I change the order the backuping TA partition in TWRP?
So may I make a backup from locked BL and TA before I unlocking my BL? Then I unlocking and making backup from unlocked TA or I just can make in your order? (Unloking - > making backup from unlocked BL -> relocking -> making backup from locked BL)
Thanks in advance.

I'm new to this kind of stuff. I tryed many Roms for the battery drop issue since Android Lolipop Update.
Dont know if it helps you but you can use Sony's Developer guide on how to unlock your bootloader or you can use flastool dot net 1 click bootloader unlock.
Open program, conect phone in fastboot, click BL button, then unlock bootloader.

where are the files and the tutorial??

This is a troll, also operator versions of z1 has their bootloader permanently locked

You, my friend, are insulting intelligence of XDA members. First of all, you can't install recovery if you have no root. Second of all, you can't unlock your bootloader if you have no root. Now understand how d*mb you sound? If I were you, I would beg the modes to wipe this thread and then get another ID or disappear forever.

Do the same without unlocking bootloader... then we have some business to do.. Hows your camera btw ? is it nice to shoot without focus ?

I've done something similar WITHOUT UNLOCKING BOOTLOADER. In my case , i have a xperia Z1 without the posibility to unlock the bootloader (Unlocking bootloader status set to NO). I have to mention that i did not have any recovery installed on my phone. I've done the following steps:
1. I flashed a KITKAT (4.4.4)(downgraded) to my Xperia Z1.
2. After that i rooted the phone with the simply root (automatic one) or one click root.
3. I've installed dual recovery for Z1 with flashtool.
4. After that , i've flashed a 5.1.1 Android(with recovery) with root, xposed and everything...(IT HAS TO BE COMPATIBLE WITH LOCKED BOOTLOADER , READ CAREFULLY IN DESCRIPTION)
5. Right now i enjoy the rooted 5.1.1 with xposed and everything
Here you have the link of the 5.1.1 flash:http://forum.xda-developers.com/xperia-z1/development/rom-z5mx-rom7-5-0extended-battery-t3224245

[Guide] [TWRP] [LB] [Deodex] Root .224 firmware BONUS Xperia X SystemUI + N-Style

Hello, before I share anything else, I did not create any of these mods. All credits go to the creators, and I am very thankful to them.. I am just excited to share this to people who are still undecided to flash these mods because of bootloops/softbricks.
I am not responsible to anything that happens to your device. ALWAYS MAKE A BACKUP FIRST BEFORE PROCEEDING
So without further ado:
Step 1. Root, Recovery, Backup Restore DRM key
I always have been using this trick to root my Xperia Z5 Dual E6633. Just remember that the link below is for Z5 Compact, but this method should work on any Z5 model, using a Z5 firmware.
http://twigstechtips.blogspot.ca/2016/04/sony-z5-compact-root-without-losing-ta.html
Step 2: Deodex your phone
I have found this Deodex patch thread by lordriguez to deodex .224 firmware. I was doubting at first if it will work on E6633 Dual .224, i risked it, and it worked with no problems. No more .odex in system/app..
http://forum.xda-developers.com/xperia-z5/development/patch-deodex-patch-firmware-200-t3301572
Step 3: Flash Xperia X SystemUI and N-Style
Flash away!
http://forum.xda-developers.com/xperia-z5/themes-apps/mod-n-style-xperia-x-systemui-v1-themes-t3368086
Thats it! Now you have:
1. Latest Marshmallow ROM (.224)
2. Root, TWRP recovery
3. Locked Bootloader
4. DRM Keys intact
5. Deodexed rom
6. Xperia X and Android N themed device
BIG Thanks and credits to:
@Twig for the complete guide to root Z5
@zxz0O0 for the awesome root
@tobias.waldvogel for the rootable kernel w/ dm-verity and SONY RIC off
@lordriguez for the deodex patch
@machao and @nreuge for the ports and sharing of Xperia X SystemUI and N-Style theme

How easy would it be to revert these changes? You mentioned creating a backup, how would one do this?

I suggest after gaining root and getting TWRP recovery to your phone, thats the time you back up. Im sure the root method works 99% of the time, unless you have the wrong resources. I suggest clean install before flashing these wonderful stuffs. Im using all these mods overnight and I have never encountered a problem, much better battery life. Overnight only 2%, compared to 4-5%, just my own experience.
Did I answer your question?

No, you don't have to unlock to back up TA, because after unlock your keys are lost.
To back them up there is the temporary iovyroot for Lollipop. You just need to downgrade. After backing up your DRM keys you can unlock your bootloader.

Just followed your instructions and everything is working fine!

Actually, using this method, the bootloader is still unlocked. It was stated on another thread (forum.xda-developers.com/xperia-z5/general/guide-rooting-unlocking-bootloader-t3354307) that uses the same method to backup ta. If you check the rootkernel tool's XDA page, you will see on the FAQ section that a locked bootloader will require kernel packages to be signed by Sony.

everythink worked fine for me. But there is a bug in supersu with with rootkernel method. If you root the kernel with this method you will get later in the supersu app "su file missing". So do the steps provided in rootkernel but dont let them install supersu. Flash it after the kernel manualy in twrp.
One question:
The bootloader is locked again but i still can flash kernel and so on ? also it only show that it is locked but it isnt ?

Thank you for this! Was having the "su file missing" problem, and this solved it
FYI, it someone else encounters this: It didn't work just to flash supersu from twrp after I included it in the kernel, I had to patch the kernel without supersu and flash it again. Then flash supersu from twrp.

Camera broken after Bootloader Unlock & Relock

Yesterday i've unlocked the bootloader and try AOSP.
Then i go back to stock rom and relocked the bootloader.
Now camera app always say, another application uses the camera and won't start.
alternative camera apps also don't work.
don't backup any drm keys.
is there any chance to get it working?

You'll need to flash a stock rom and wipe everything in the process.

I had the same problem and flashing using the flashtool with all wipe options checked didn't fix the problem. Any other ideas?

I would assume that relocking it without the DRM keys has broken it. To rewrite the TA backup img to the phone you have to use flashtool version 922.3 If I was in your position with or without a drm backup I would try using that version of the flashtool to flash a FW and try the relock procedure again to see if it makes a difference. Have you unlocked it again to see if it brings the camera back?

Ok I unlocked the device again using Sony Mobile Flasher. I'm now flashing an Android 6 ftf file from the UK. I have the TA backup img but am not sure how to restore it. Apparently the Backup TA version 1 had a restore option in the CMD menu. But all the 2nd version does is backup a TA partition key from what I can tell.
Any help restoring the key would be greatly appreciated.
Edit: Ok now I've booted up without locking the boot loader and the camera is working. So now I should be able to lock the bootloader and have it stay working right? But how do I do that?

Lets see. Download Flashtool version 9.22.3 and download Rootkernel, use RK to create a DK.ftf from your TA.img then flash that using the 9.22.3 version of the flashtool. To create a DK.ftf open a cmd window in the Rootkernel folder and enter flash_dk TA.img DK.ftf.

Thank you for the help.
I was using a higher version of the Flashtool so I found the 9.22.3 version and got that installed. I found the Rootkernel and used it to create a DK.ftf successfully from my TA.img.
I flashed that successfully and rebooted the phone but it didn't work. This also didn't automatically relock the device like I read it should of.
I then started over by flashing the Android 6.0 ftf file again. Then I used the flashtool to relock the device. Finally, I flashed the DK.ftf file one more time.
I just booted up the phone and now the camera isn't working with the same error I had before. I also checked the security menu of the phone and it still says the DRM files are not there.
I'm really not sure why it's not working.

EDIT: See below.

Lets try one last thing. From reading the threads here apparently flashing the DK.ftf is only for those with an unlocked BL wanting to keep DRM functions so places the TA in a location that DRM-fix kernels can pickup. To rewrite the original partition you have to do the following...

...if this way fails then it's time to talk to Sony or just run an unlocked BL permanently.

Flashing DK.ftf isn't enough. You need to make a boot.img with DRM fix as well using rootkernel.
