Hi guys!
I've read several threads about loosing the BIONZ after unlocking the bootloader. Some say it depends on DRM, some say it has nothing to do with. It's possible to regain it after relocking the BL?
What is truth about this?
Unlocking bootloader makes no change to software...just make sure u have a TA backup....

Actually it does make a lot of changes to the software. Just take a look at the stock rom logcat straight after booting. There's a check if bl is unlocked and if it is then it wipes some stuff.
TA backup is very important before unlocking it so u can go back to LB and send your phone in for a warranty. I can't tell what's up with the bionz as I've unlocked my BL and then restored it, but the camera doesn't seem to be as good as it was. That might be caused by 4.4 firmware though. Can't tell for sure.

I unlocked and Track ID working like always. Do you want a vid?
Woot? I just say that track id works even without DRM. And its not market downloaded

some unlock bootloader guys confirm track ID work but they cant use update music info feature in walkman app, x-reality stop working, picture quality lower than lockbootloader
( im not sure, just read from google, should we make a thread to vote and confirm what feature stop working after unlock bootloader ?)
I can say it like this then.
I unlocked lost drm keys forever. I relocked my phone using flashtool. Drm keys still not there according to what we know.
But all the functions you mention works. I've compared pictures with ones that comes from a locked bl with never was unlocked. They are the same quality. The other functions you mention works aswell.
And remember now, I don't have any drm keys. But I have relocked bl. I unlocked last night again. And I actually checked these things just to see and guess what. They all still worked.

So, guys, can you say exactly, does the xloud with BE2 works ofter BL unlocking or not ? This is very important, and i can`t find unequivocal answer to this question.

They r DRM, so unlocking BL means losing them forever.
u can relock BL again and restore them back, it worked with XS but i dont know if any dev was able to relock XZ

I have a question... I try the leaked 4.3 ROM by DooMLoRD, but it works really really really bad for me!
Now i RE-LOCK my bootloader and i flash stock rom. I am wondering if now my phone is still rooted and if i can get the 4.3 update when is released...?
You will have lost root by flashing stock ROM... by going back to stock you will get updates via phone and PCC.

@Jared89 if u have took the backup of TA partition.
And then relocked the BL with the latest flashtool and restore the TA then u will be as good a new.
U can get all the updates.

U can still flash the latest official when released.
So its not a worry.

I noticed that my phone is not working the same way as before unlocking the bootloader. Is slower now.
Anyway... Is there any other way to make my phone like NEW... like i never unlocked the bootloader ?

Hello everyone,I have a question here...
My XSP bootloader is unlocked, and now I want to relock it...
But,when I unlock it, I forgot to backup my DRM keys...
Can I relock it without using the DRM keys?
Thank you before..

Everything works for me too with unlocked bootloader. Except for OTA updates.
It's really? I forgot to backup my TA and DRM keys while I was unlocking bootloader. Re-locking bootloader will bring my Bravia Engine back?

I have an Xperia SP currently running 4.1.2 rooted, bootloader locked.
My aim is to upgrade to 4.3.3 and root, for which i will have to unlock the bootloader. To do so I need a TA partition backup , for which again, root is required.
So, my question is that is it okay if I take a TA Backup now [in 4.1.2] and then upgrade OTA and unlock bootloader, root and then restore the 4.1.2 TA backup onto 4.3.3 in order to restore DRM keys and Relock the bootloader?
Has anyone done this?
is it safe?

Yes, TA partition is not firmware related you can restore it in any stock firmware (don't try to restore your TA on a custom rom) test your back up first and make a many copy

Can you install the OTA update with that unlocked bootloader?
Mine is unlocked too.
I received a new firmware update, not installed it yet.
But my previous updates, such as Walkman, movies, and album are able to be installed via OTA update...

Hi all,
I'm not new to this game, I used to have an S3 & S4 but I am new to rooting the Z1, I've read about losing the Bravia Engine and DRM keys by rooting, but in basic terms, what does that actually mean?

You lose the keys only when you unlock the bootloader

How can I tell if my boot loader is already unlocked? And what does losing the keys mean? What will it stop me doing?
Sent from my C6903 using xda app-developers app
From my knowledge If you lose your keys you won't be able to use Sony services like music unlimited etc and I think you can't play aac files ...Bravia engine is just an image and video enhancer...like X reality...most z1's if not all come with locked bootloader specially if you got it from a carrier...and btw u don't need to unlock your bootloader to get root...there is a video around here and a few guides so go and have a look...have fun

Mine isn't from a carrier, its factory unlocked

TO CHECK IF BOOTLOADER IS UNLOCKED:
Dial *#*#7378423#*#* and goto service info / configuration
if the last line says
bootloader unlocked: Yes
Then its unlocked
if it says
bootloader unlocked allowed: Yes
then it is locked but you can unlock it
if it says
bootloader unlock allowed: No
then you cannot unlock it
LOSING DRM KEYS
DRM stands for "Digital Rights Management", and mainly is used with sold eBooks/PDFs and the like (and also for sold music files plus maybe even videos). Those keys are to identify your ID as to prove if you have permission to access those documents.
Losing these on your device means NO:
X-Reality - if you cant tell whether this is on or off/ it takes effort to tell them you probably don't need that (you can get this back using a mod in the development section)
BIONZ- makes photos look better, but its not that bad unless you're OCD about pictures.
More GRAINY IMAGES - maybe because of loss of BIONZ? I don't know but tbh its not that bad and images are still good to me.
Download Music Info - it works for me but some say it doesn't may be it works because of the X-Reality mod? someone can correct me if Im wrong.
And other stuff you probably wont notice cause i and many others haven't. it really depends on you but from my experience life is a lot more fun with unlocked bootloader.

Bro =>downgrade =>root =>Back up TA =>upgrade to 4.3 => Unlock bootloader => ROOT => Custom kernel=> have FUN!
Wow that's great, thanks for all the info, so even of I root andflash a custom ROM, going back to stock means I get the DRM keys back?

I have the single sim international version of the z3+ and it says the Bootloader is unlockable in the service menu. So the question is how do I go about getting it unlocked?
Sent from my E6553 using Tapatalk
If it's indicated as unlockable, then there's no way to unlock it.
There should be instruction on Sony's website. Unlocking bootloader doesn't do anything for you unless you know what you're doing. It doesn't give you root access but erases your TA partition where you will lose all of Sony's DRM keys.
I'm aware of what unlocking the Bootloader does. Honestly don't care about drm or warranties as I never have phone long enough to break them anyway.

Sorry, I may have read it wrong and replied too fast. To clear any doubts, please indicate what exactly is stated in the menu. Is it "Bootloader unlocked allowed: Yes"?
In any case, this is the Sony site to unlock your bootloader: http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
That being said, I don't see why you would want to unlock your bootloader now. There are no custom ROMs or kernels developed for the Z3+ yet. You can't even root it.

Got a question
Got unlocked bootloader without possible root (5.0.2v 28.0.A.8.266 firmware E6533 (z3+ Dual)). Used flashtool before unlock and saved S1 Dump in Advanced menu. Is it possible to get DRM keys from S1 Dump and restore bootloader lock?
you should downgrade to the 251 firmware so you can flash the modded stock kernel for root access.im using imagebreaker kernel. check out zrom also
Ok pikeylfc,
I see that imagebreaker kernel is for e6553 device. Mine is e6533 (Dual sim)... I doubt if the same kernel can be used... It has different hardware.

Not necessarily. When you have active myXperia service, service tests will show, that bootloader is not unlockable. Try to disable myXperia (Settings -> Lockscreen and security -> Protection in myxperia (or something like that) -> disable/deactivate). Then reboot your phone and check again. It's high probability, that bootloader change state to unlockable in service tests. myXperia is asking you to turn on in initial configuration (if you have new phone or after wipe), and most people turn it on by default and forget it.
