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?

Hello! If i unlock my bootloader on my xperia neo and then lock it again will i lose my warranty?(i want to root my phone and seems that OTA update is not working so i want to try the method wich implies unlocking the bootloader)Thanks in advance!
Yes you will, unlocking bootloader deletes DRM certificates so even if you relock, sony will be able to tell i beleve the payed method of bootloader unlock does not delete the certificates though

Hello.
To root your phone you just have to downgrade to a 2.3.2 rom with wotanclient, root with gingerbreak and do an OTA update (no danger during the update as long as your bootloader is locked)

Is DRM keys the only big issue? If so, I can see that that can be worked around. I asked Sony about this today and they said that a lot of issues they see with their phones are as a result of modding, so if the BL is unlocked, you lose your warranty. I don't want to ruin a 2 year warranty on new phone. Yet, as Doomlord pointed out, Sony offered users to test the ICS which involved BL unlock...I'm confused.
After i unlocked and rooted my arc s, i can't update my phone through sesu. Thus i want to ask that sony arc s bootloader can be relocked now?
I found a thread but it was deleted because of posting in the wrong section.

Just one more question, is there any thing difference between a new phone and a relocked phone? Thank you.
Thank you.
No one ?
Hello, I have been waiting for 1 month
dont know if you can relock bootoloader.
Difrence is that if you unlock bootloader you will never ever be able to have mobile bravia engine, track id and some sort of stuff.
Unlocked bootloader can instal cyanogenMOD (custom ROM, which is powerfull and good)
Locked cant do that, but can recive Sony Updates
Up... same question... we will be able to relock our arc s? Please answer!

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...
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.
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.
