Restore Bravia Engine After Bootloader Unlocking.( Simple & Easiest Method) [SHARE]
Here is the most easiest way to restore bravia engine even though you lost your drm keys..
Note : This mods works 100% and this mod doesn't bring back your lost drm keys but this restores the functions of drm
Required Things Before Starting :
Stock Based 4.3 ROM(.205 kernel/.207kernel) ,Flashtool,Restore Bravia engine zip file,cwm/twrp recovery,Root Explorer..
Step 1. Power off your unlocked phone/locked with no drm keys
Step 2. Follow this if your boot loader is unlocked only.
Open Flash tool and click blu icon now.
Then you will be asked to connect your device in flash mode(Hold volume down and then press power button,then plugin the usb cable and you will get green light) Now you will be asked to relock your boot loader. Click relock and now your boot loader is locked.
Disconnect your device
Step 3: then go to recovery flash the restore bravia engine zip and reboot.
Step 4: Go to album now, you will get "Unfortunately credential manager service has stopped".
step 5 : Using root explorer mount system in r/o mode and go to system->apps and delete credential manager.apk(noteelete credential manager.odex if your rom is odexed).
Step 6: Reboot your device once again now.
Step 7: Once Again go to recovery and flash the same "restore bravia engine.ip" and now reboot again.
(Note: when flashing the restore bravia zip second time , if your rom supports x-reality engine such as existenz ultra rom v4 then flash the x-reality zip along with the restore bravia engine and then reboot)
Step 8: Now go to settings and check whether bravia/x-reality is enabled
Then check the difference in movies and album app.
YIPEE U GOT THE BRAVIA ENGINE BACK..

Great! thanks for sharing, I already tried a lot of methods, but they only worked on .257 roms, this worked for me (A.1.207 based rom)

No need of restoring TA partition and i too lost my TA a long ago dude. First relock ur bootloader using the flash tool and then apply this mod.
It will work 100% if u are on stock .205 or .207 kernel........

Omg why do you speak when you don't know anything. You can make a ta backup and unlock you bootloader, then you can lock it and restore drm keys. I am asking something way different.

Will this work if I have installed Williams Kernel v8? IMO stock kernel does not have recovery so how to flash the second time without changing kernel?

is it work with bravia engine 2 ?

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.

This guide will restore the drm keys for the sony features to work again(camera x-reality etc...)
not ur original keys,,added zip drm restore zip in first post

Deleted

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?

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.

Relocking Bootloader

Is there a way to relock bootloader? I tried flashing stock rom via TWRP but the prompt still shows that Device cannot be trusted blalbla unlocked.
Can anyone give me a way how to relock my BL? I also tried SRK tool with relock bootloader with my Unlock code, but it doesnt work.
Thanks
EDIT: Please lock thread. I tried locking via eRecovery and it worked. Thanks

Update your device. Use the full update rom like b161, 201 or whatever you like. That will remove the unlocked bootloader and root as well.

Yes is tested: at any update (via dialer or three key pressed) with stock firmware, you lose root, twrp and unlocked bootloader (if you have root, twrp and bootloader unlocked).

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...

CONFIRMATION OF TA RESTORE!
- Unlocked bootloader
- Flashed TWRP
- Pushed TAbackup.img (I renamed it) to /data/local/tmp
- Did
Code:
adb shell dd if=/data/local/tmp/TAbackup.img of=/dev/block/bootdevice/by-name/TA
- Rebooted
- Everything back as it was. Original TA restored and DRM keys all active:victory:

NOTE/EDIT: Due to dm-verity, you cannot restore TA on a rooted phone (Z3+ onwards). It won't boot up. Boot and system have to be pure untouched stock.

...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.

Relocking bootloader. Is it possible to keep TA?

Hi!
I was wondering what will happen with the drm keys and TA partition if I would want to relock my bootloader?
I used the dirtycow method to back up and restore my TA partition when I unlocked the phone, but will the camera and other TA related stuff still work if I relock it?
In other words, is it possible to return the phone into "factory state" if it has been unoocked with the TA partition backed up, or does relocking bootloader also empy TA and erase the DRM keys?

Search XDA for relock bootloader. It's been a while and I can't remember exactly, but if you have your backup you can restore it and relock bl somehow.
https://www.google.com/search?ei=R5...13i30j0i67j0i22i10i30j33i22i29i30.lwUunOAEvP4
BTW - practically speaking, don't feel the need to relock it. If you have your TA restored, it's just as good as new. Only if you need to send it to Sony and need it to be locked for warranty purposes.

I was thinking for the possibily to relock the bootloader to get OTA updates working if I want to give the phone to someone not that into tech, who doesn't need root. But I don't know if the phone is updated by Sony anymore anyway...
