Hi I just unlocked bootloader on phone by this tutorial http://forum.xda-developers.com/showthread.php?t=2354721 . As I read after the unlocking I should lost DRM keys and because of loss of the DRM keys the services as a Bravia Engine 2 ,TrackID and such Sony stuff shouldnt work. However after the unlock it seems these services still works. In configuration it says "bootloader unlocked: yes"
If the unlocking was succesful ,shouldnt be the box of Bravia Engine 2 in the settings be grayed out and unresponsible? How can I be sure if its unlocked? I dont want to mess my phone when I flash a new ROM on it.

You looked in the Service menu (*#*#7378423#*#*) that means it is unlocked. Box with bravia engine 2 shall function like before, there is just no effect. If confoguration sais that the bootloader is unlocked it IS unlocked! the Sony stuff only doesn't work if you didn't root before unlocking the bootloader

Hi everyone,
So I picked up my Xperia Z a week ago to replace my HTC one, yes I gave up those dual speakers and snapdragon 600 hardware and camera lens cracking eventually.. Anyway for a while I was puzzled as to why my phone wouldn't unlock bootloader, followed all procedures as the OP asked and still bootloop, When I checked *#*#service#*#*, rooting status said "Bootloader unlocked: yes". I didn't know my bootloader was indeed unlocked from the previous owner. Now i'm using "RomAur v8.1" unlock bootloader selected. Now back to my question, in settings -> display "Mobile Bravia Engine 2" shows up and I didn't restore my TA partition. Is it normal for Bravia Engine 2 to be there after flashing unlocked roms?
Yes, it's normal, unlocking bl doesnt remove the be2 window, however youre not able to use it anymore (probably works in movies) unless you have TA partition

I backed up my TA partition when it was on factory firmware. What is weird was the bootloader was unlocked when i got it and it. Anyway thanks for your reply!
Tried searching, but didn't find a clear answer to the disadvantages of unlocking bootloader for Sony Xperia SP.
Am really interested in unlocking bootloader, mainly coz I am a fan of CyanogenMod ROM's.
If an when CM arrives for SP, I will have to unlock bootloader.
If some doubts are cleared, will unlock it right away. May be.
Few questions, simply answered would really be appreciated.
1. We lose DRM is sure, but can we manage to add DRM keys back on unlocked bootloader?
2. Do we lose Bravia Engine 2?
3. Do we lose front camera?
4. Any other disadvantages? Or something I need to know?
Thanks!
1. Yes, backup TA: http://forum.xda-developers.com/showthread.php?t=2292598
2. Yes (unless you follow step 1). I prefer not having bravia engine because I noticed it made pictures taken by our camera look a million times more noisy
3. Well that's just a weird thing to lose... No we don't
4. Not really... Apart from the warranty void stuff of course
Not sure if you need to unlock bootloader to install CM though. If they made it work with stock kernel then you won't need to unlock the bootloader, if it only works with modified kernels then yeah you have to unlock
Unfortunately I did root my phone and unlocked bootloader without paying much attention to backup TA partition and possibility to lose Bravia engine
I should have done more reading instead of rushing to root my Xperia SP
can I know what is DRM keys that have been lost ?!! and if i relock bootloader will I restore Bravia engine.
also if Bravia engine is lost, how come i still can select it in Settings --> Display
is there anyway to test if it is there or not?
Thanks.

Yes bravia engine is lost
It still appears in settings but u will find the difrence in pictures that the bravia engine doesnt work after unlocking bl
Heres the thing guys, I unlocked bootloader on My V and J and still found Bravia working on the albums, I did not backup TA or whatsoever.
Its just placebo that it will be gone. I unlocked bL on both V and J because warranty is gone after a year.
The bravia engine only makes photographs look better on the phone. Sometimes think Sony chose less bright screen hardware just to make BE look good.

Hi!
I think you will find an answer of these question in this thread: link
1.Yes, you can restore the DRM keys if you made a BACKUP! Just flash stock firmware before you do that.
2.Yes, but thats only counts for stock rom.It works fine on custom roms.
3.No.
4.I dont know. My bootloader is unlocked and I have no issues so far.
I hope that helped!Press thanks if it did!

Guys need your help about this matter, I just bought my xperia z1 a week ago and i already rooted it... So my question is can i still back up my TA? I did not tamper my bootloader..how will i know if my bootloader is unlocked?
My process in rooting my xperia z1 is:
1st I downgrade my xperia z1 in 14.1.G.1.534 firmware and rooted it using vroot then upgrade it to the latest firmware which is 14.1.G.2.257... BTW I uninstall the vroot superuser because it's in chinese language and I can't understand it, but I replaced it Superuser in playstore and it works fine!...Thanks~

unless u visited the bootloader unlock website and requested for a key which involved keying in your imei number and then using fastboot to unlock bootloader, it's fine...
u can verify by checking if bravie engine works... or dial *#*#7378423#*#* and going to service info > config > rooting status

No, it means you are allowed to unlock it, but you have not done it yet otherwise it would say
bootloader unlocked: yes

trust me, you cannot accidentally unlock it...
Hahaha chewdaniel says to look at sevices menu if it's unlocked and i saw the word "yes" i thought i accidentally unlock it when performing to root it..i feel nervous when i saw it haha!
sent from future!
1. visit bootloader unlock website
2. key in your imei number
3. receive an email with unlock code
4. FINDING & INSTALLING FASTBOOT DRIVERS, while phone is in Fastboot state
5. entering bootloader unlock command with a very long and complicated unlock code
so yea... like Greg said... there's no way u can "accidentally unlock" it
I had already rooted my z1 when on 4.2.2... But now the 4.3 updates removed the root... Unlocking bootloader ia only option as far as I know.. So I want to ask is..
A) if I unlock bootloader will I loose xreality engine? If yes how do I save that from not happening..
B) is there a "stable" way to install CWM recovery amd not unlock bootloader..? Is there is.. Will mybstock features be affected such as loss of xreality n DRM keys?
C) is there a way to unlock bootloader without looaing DRM keys? If so again will I loose the z1 features?
Please help..

A) if you unlock bootloader you WILL loose xreality. To get it back restore backed up TA partition. You can't have unlocked bootloader and xreality at the same time. Here is a video on how to get full root on 4.3: http://youtu.be/1aq9YTlfCgc
B) Yes you can install the recovery on any rooted Xperia Z1. You don't need an unlocked bootloader to be rooted.
Here are some more explanations if you are confused http://youtu.be/l78p_2ShPS0
C) You will always loose DRM keys when unlocking but you can back them up before unlocking to restore them later
Out there are 2 ways only how to root your Z1, both are for Locked Bootlader. 1 best way is here step by step, page 2, Post #16 http://forum.xda-developers.com/show...2588331&page=2 or NUT method here http://forum.xda-developers.com/show....php?t=2572988
..and what @shem2409 said it's all right.
I've recently bought a used xperia z but I'm not sure if the bootloader is locked or unlocked.
So my questions are:
1)How do I check this?
2)If the bootloader is locked does this guarantee me that the (stock) rom has not been "modified" previously?
My concerns at security related.

type *#*#7378423#*#* in the phone dialer
then service info>configuration>rooting status
we will have locked bootloader when we bought it
and no bootloader can be unlocked & relocked so don't know,or you can check if the BRAVIA Engine works on Sony Album app or not

According to this link you can but not entirely sure since I've never done it before..
If this if not the case, could you explain to me a little bit more?
It's possible to unlock and relock the bootloader without leaving any trace that it was done. You can check if it's currently unlocked by looking in the service menu. Enter *#*#7378423#*#* in the dialler, then look in Service info - Configuration.
If you're worried just repair the phone with SUS or the PC Companion. This will completely wipe the phone and reinstall the software from scratch, therefore ensuring that nothing is tampered with.
