You will lose DRM keys which I believe is required for trackid. Bravia engine... Nope

Press the thanks button if I helped.

Lost my Bravia, TrackID, and download track info on JB. Seems like it's permanent, too, but I haven't restored pre-unlocked TA and relocked bl yet. Some say that works.
xGO / GB.184 / Munjeni.v6 / BLUL / Debloated

You will lose bravia engine but track id can work.Just re-download it from play store and it would work.I have working track id and download music info in walkman(latest walkman).
No,you will not lose them permanently.Check this thread.I didn't tried it but i am sure it will work.

Its not permenent, Dont Worry.
I got my DRM keys back with working BE and Track id.
You can get your DRM keys back by Flashing Relock for your device by Including TA partition during flash.

Yes I'd surely help you out.
I've followed the steps from here ---> [Backup Your TA Partition Before You Unlock Your Bootloader]
The above steps apply if you have not unlocked your bootloader.
_______________________________________________________________________________________
If you have unlocked it,
Follow the steps below.
What you Need?
Flashtool
Stock ROM for Your Phone Model Download Stock ROMS from Here ---> Stock Xperia U XDA
Relock File for your phone
How to proceed :
Using flashtool
First flash only the STOCK ROM Using Flashmode
(Exclude TA Partition In The Right Hand Side Options In Flashmode)
After A Complete Flash
Reboot The Phone Let it Settle Down A Bit
Now Again Using Using Flashtool
Flash The Relock File For Your Phone, Relock File ----> [HERE]
(This Time Include TA partition)
Flash!
Reboot
Your Phone Will Be As Good As New
I hope this information helps.
Do reply with your progress.

[DEV] Reloading kernel without rebooting

Check my last post in this thread for more info.
-----------------------------------------------------------
We have everything we need,all patches are done and we know how to genereate RCH_K key that was bootloader unlockable phones only had big thank wilsey for discovering this.
As I said I need testers,its little risky because we are writing,000007DA,it should enable fastboot and change service status,if it doesnt we will write modifications manually.
If you want to test PM me with following info.
1. Your bootloader Unlock key
2. Your TA backup
Send me this info and I will send you instructions and patches for your phone.
------------------------------------------------------------------------------
How to backup TA:
You need:
1. Flashtool
2. Notepad++
3. Phone?
Download and install flashtool.
Link: http://androxyde.github.com/
After you do that:
1. Modify config.properties (located in root of flashtool install dir) to look like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
2.Open flashtool,select "Advanced" and "Backup and Restore TA"
3. It will open this window
Click "OK"
4.Follow instructions and connect phone in "Flash Mode"
TA is saved in Flashtool/custom/ta/
ZIP files and upload them and post link here.
I have patch,who wants to test it just PM me with your bootloader unlock code you get from Sony site.
I wanted this petition in English

Thanks for info,it looks there are two types of OPS and also after flashing TA you still need unlock code.
And thats it.
Anyway as he said take simlock.ta from seus package and change OP_NAME to what it says in it and then normally flash.

[Q] How to upgrade to 5.1 from stock rooted 5.0.2

Hi my friends.
I follow this tutorial ([Stock][Lollipop 5.0.2][Root & Recovery][LB] D6502/6503 23.1.A.1.28 | Complete Guide) months ago to install Android 5.0.2 on my Xperia Z2.
Its ok.. everything is working great.
Now I want upgrade to 5.1... but when I download some ROMs (first was crdroid-5.1.1-20150703-sirius) and flash it, my Z2 brick (red light).
What am I doing wrong?

This tutorial is for LB (Locked Bootloader). To flash AOSP based ROMs e.g. CRDroid you must unlock bootloader because of custom kernel, which Bootloader doesn't permit to boot.

You're right.
My bootloader is locked =/ I check the "marlin key" and it's active.. some users say when is active = bootloader locked, and error = unlocked.
Anyway, thanks so much for you time!
No problem bro
Error occurs because of lack of drm keys. If u want to unlock bootloader remember to backup Drm keys

Unlocking bootloader wipes all internal memory and loses DRM Keys, so before unlocking backup them. .
How to backup DRM Keys: http://forum.xda-developers.com/showthread.php?t=2292598 - remember to upload this backup to online server(s) to be sure you will not lose this keys because these keys are assigned only to your phone, so if you try using another DRM Keys you'll brick your phone.
Then you can unlock bootloader and in case of any problems with Z2 flash stock rom and restore DRM Keys - bootloader will automatically lock, and warranty will apply

Unlocking Bootloader

Ladies and gents,
Any downsides on unlocking bootloader?
Is Camera working properly? TrackID? Others?
All works perfectly... tested on E2303
@alby_var
I tried to unlock. However, I believe once you´re on fastboot mode, Flashtool should recognize your device (mydevices) and your ulcode.txt.
Field came blank. Did not work. My flashtool is 19.0, so I don't have a "custom" folder. It's C:\User\.flashtool\mydevices\BY900FGM8D\ulcode.txt, and I don't know if this is right (I mean, device and ulcode are right; I wonder about the folder).
Edit: Solved. New folder and ulcode.txt should go to C:\Users\YourUser\.flashtool\registered Devices

you may not see the difference, but the quality will be bad - transfer the pics to a computer and check the quality , and your warranty is void now.
Of-course, you will lose your DRM keys
You can check your DRM Keys at *#*#SERVICE#*#* (in your phone dial pad type *#*#7378423#*#*) >Service Test>Security and check if all the entries says "Key OK" then you are good and have not lost anything. If any entry says "Unknown" then you have lost that particular DRM Key.
Can you check and show a screenshot with Drm keys lost?

you can check this post below for any more details
http://forum.xda-developers.com/showthread.php?t=2765813
Edit: Once you unlock your boot loader, the DRM Keys are lost, the only what to recover is to make a backup of your TA partition.
To make a backup of the TA partition you need root access. That means you should root your phone even before you unlock the bootloader.
You cannot use the TA backup of a different phone (same model or not), as this will permanently brick your phone and cannot be repaired. the TA backup has to be of your phone only as the DRM Keys are unique to each phone.

When losting DRM keys mean nothing break and camera and other apps are normal, is any reason to wait for prerooted firmware or i can unlock it? But... When losting DRM keys mean nothing happen, why are here these DRM keys? ...

My Advice, dont even think of unlocking your Bootloader, with out a TA Backup, wait for a root exploit to be identified and take a backup of the TA partition, before you do anything.
I had a bad experience on my Xperia Z, after UB, the camera software has some code to check for DRM Keys and if they are missing, the App still works, but the picture quality was BAD, i mean really BAD a lot of noise in the pictures. unfortunately i did not backup the DRM Keys, so my warranty was void and had to live with a bad camera when using stock firmware. I move to CyanogenMod after that for some decent picture quality.
