Hi Developers.
I got a sony xperia sp phone and today I tried it unlocking the bootloader. I was thinking about it from a long time but today I somehow did it.
Guys. I was not knowing to take TA backup of my phone and after unlocking the bootloader I am facing the problems. I have attached the screenshot of the problem while taking the TA backup and backup was not created. I have not flashed it yet.
Please tell me will the bravia engine for my phone will work or not. It's gonna be horrible for me if it don't. Help me out with this.

i want to unlock Sony ericson xperia pro (mk16i) to install custom roms
But i m worried about warranty issue...
Is relocking boot loader of my device Mk16i recovers warranty???...
you can unlock your bootloader by 2 methods
1)doing it thru official sony website
2)test point method...
when done using official sony website, you lose your drm keys(useless) but thru test point method you dont lose those..however, relocking bootloader can only be done on sony unlocked bootloaders to gain your warranty back.....
hit thanks if i helped.

First of all Many many Thanx for reply, Because i was waiting for reply many hours...
Actually i have unlocked xperia pro boot loader without any safety knownlodge but know i relise...
So relocking bootloader will back warranty again??ARE U 100% SURE????
is there any danger from deleting drm files to warranty?
i m going to hit thanx button on ur reply, please reply fast
see drm keys are used only for stupid purposes like trackid and othr utterly useless stuff drm keys never cause problems for warranty because people who use their phones normally can also lose those drm keys...
and yes, relocking a bootloader will give you back your warranty(thanks to sony who does not keep a record of unlocked bootloader phone's imei number)
but remember that relocking can only be done on bootloders that are unlocked using the official method...
Hey, I'm about to sell my phone, so I need to get it to its factory state. Prefably so that the guy that buys it could send it over for repairs if needed.
And so I did not backup the TA partition. From what I've read that means no relocking the bootloader. Fine.
But how do I go back to the original 4.1.2 sony-branded system?
I'm currently on CM11. Can I just use Sony Companion to perform the update, is it safe? What steps should I undertake?
As far as I know, Sony Update Service won't work with unlocked bootloader (I may be wrong), however, you just need Flashtool and a FTF from the latest stock firmware for Xperia M single SIM (currently at 15.1.C.2.8)
Sorry mate but you can't lock your bootloader without DRM keys(TA PARTITION BACKUP).
You can flash stock ROM using FTF flashtool and but i cant relock your bootloader but you will get stock rom back.
Warranty is void now!!
Sh!t. That's not good.
Thank you guys for answers!
One more thing.
Is it possible to receive OTA updates after I unlocked bootloader and flashed the stock firmware with flashtool?
No once bootloader is unlocked it bricks the device doing ota updates

Sh!tness. So I guess I'm stuck with the phone forever.
Thanks!
Further info for future Xperia phones you may buy: when you unlock your bootloader your DRM keys get wiped, without them, OTA updates, Mobile Bravia Engine (in models that have them -- not the case for Xperia M), Track ID, Download Music Info and SensME (alongside some other proprietary apps/features) will not work, even if you flash stock firmware again.
Before unlocking your bootloader it's always recommended to do a TA backup first, so, if you need, you can relock your bootloader to get your DRM keys back and make proprietary Sony apps/features working again. Since you didn't backup your TA partition before unlocking, you are out of luck now and there is no way of relocking your bootloader.
Also, DO NOT EVER TRY restoring a TA backup from another device (even if it's exactly the same model), TA partition contain some unique info and flashing a TA backup from another device will permanently hard brick your phone...
Well that's a very comprehensive answer! Thanks!

go to service centre tell them that you were doing a 4.3 update and this happened.they wont recognise that your phone has an unlocked bootloader bcoz it doesnt start!they will replace it make sure you dont have cwm installed.

Hello.
I have a Xperia Z1c, bootloader unlocked and rooted, on 4.4.2 (14.3.A.0.757). I tried mirrorlink with my Sony XAV602BT car audio and get an error when connecting (error code 42). It worked with my xperia SP so I don't thing the car unit is faulty.
Do you thing DRM rights may be a cause (I unlocked bootloader) ?
Thanks
Possibly, I can't use NFC with my W9 Bravia and put it down to the fact that my BL is unlocked, where as my locked BL Z had no issues. They do warn you this might happen so can't complain really.
Sent from the app on my Z1C...
no complain at all... just want to know.
I will restore TA and see...
Yep... Coming back to locked BL with TA and mirrorlink works.
Have the same Problem with a Xperia Z1 compact, what is the meaning of TA?
Hi,
New to the forums and did a little snooping before posting. I recently bought a z1c australian stock and it came rooted and with the bootloader unlocked. I don't have the original DRM keys nor the TA backup. Is it still possible for me to relock the bootloader? I can't seem to update my phone via PC companion without locking it.
Thanks
Download Flashtool it lets you relock your phone

Yes, you can re-lock the bootloader, but Your DRM keys are lost unfortunately. As said in earlier post, you can use flashtool to do so. Also, there is a thread which helps You get back some of the features provided by DRM keys, although do note it does not restore DRM keys. You can find the thread here.
