i have sony xperia s , unlocked boot loader , rooted , cm9
iam willing to relock my bootloader when a stock JB rom is avialable from sony so when i was backing up some apps on titanium backup i saw an option to back up some thing with a long name that contains DRM Codes is this helpful , so relock boot loader , root and then restore them through titanium back up , does it work ?

nopes, DRM is on the kernel, when you unlock your bootloaded DRM keys will be erase. You can't never ever get it back !! :cyclops:, but DRM keys are not necessary for me actually

I think album art downloading in Walkman is the only thing that breaks.
Seems that the location button on the messaging menu also doesn't work.
"I got my values. So you can keep yours, OK?"
But what if we knew where they were, so somebody can extract those before unlocking the BL...? And then we can restore them?
If they're on the kernel, is there no way to remake the stock kernel with DRM keys??
Track id also does not work
Who bothers we can download it from Google play again
If drm keys are on kernel.. Can a copy of stock kernel be made to preserve those drm keys?

Not on kernel I think...
Because update also contains a new kernel...
One more thing, Search option in geotag of album app is also not working...

But an official Sony update wouldn't delete official Sony data! So what if DRM keys are in BOTH kernels?
Also, how can we make a copy of the kernel? I'd do it, if I only knew how...

He meant with unlocked bootloader. Still, strange, works for me even unlocked.
"What really matters in this world, anyway?"
TrackID works even with unlocked BL, what is not working since drm keys are gone it's the "download music info" that is another thing!
Its already gone so no use!

Hi, I just upgraded from ArcS to Xperia S, and bought a proper sim-free Xperia S. I did the test in the service menu, and it says Bootloader unlock allowed.
Now i'm guessing when you unlock, that you lose DRM keys and other stuff (like the Arc did). I only really want root, without losing anything that I can't get back.
What's the best method? Is unlocking the bootloader the only option open to me?
Thanks.

Hello Guys,
Recently I've unlocked my Xperia S bootloader and then upgraded it to ICS UK fw.
Because of the "DRM" thing i cant use that "find music info" feature.
In order to solve this problem i've locked my bootloader again, installed the original fw (UK ICS) and did a factory reset. But even though this feature is not working. So, is there anything that i can do to solve this situation? I really ejoyed this feature..
Thanks in advance,

Not only the album art, but the music name as well. I used to transfer some MP3 as "Track 01, Track 02, .." and then the walkmap app just updated with the correct name, for an example. I just had to use the option "Download music info" and it worked.
Anyway, is there a way to make it work again? As i told you, i've unlocked and then re-locked my bootloader.
Thanks in advance,

Well as someone said the DRM keys are lost when you unlock your bootloader, even if you relock it it wont come back, for me i understand its like a license, and they are lost for security (I read that to protect their apps or something like that.... im not pretty sure) but the thing here is that you cant get your DRM keys, so you cant use this feature , try with media go to obtain the album art and all that stuff :silly:

I've checked with some people, and they report that even though they haven't unlocked bootloader or flashed anything to the phone., they still CANNOT download music info. It still results in an error.
Could it be a country specific thing due to licensing?
My country is Singapore and the people I've checked with are also from Singapore.
Also, I've found this: http://communities-origin.sonyericsson.com/message/236937#236937
Installed the apk but didn't work. Or must it be flashed for it to work?
It works for me. Don't forget to delete app\CredentialManagerService.odex.

You cannot flash kernels in locked bootloader.. And most of the mods are also there for unlocked one.. Unlocked bootloader has very few Roms.. Better unlock it and experience a whole new world for your phone
There's no different in apps or mod.
But there's rom. Most rom here are build for unlock bootloader, u can overclock and stuff.
Pretty cool but u will lose DRM keys. So no more "download music info" in walkman. All apps that need DRM keys won't work,

Yes it is, and there are guides in this forums by DoomLord.

This and other mentioned are RESULTS of difference but where is difference ITSELF ?
WHY cant I flash any kernel except stock ?
Don't tell me "because you go brick".
It is RESULT.
I can flash stock rom and it communicates with locked BL however - I think - new stock rom has it's own management of booting.
Then - base question is NOT explained and I am really curious of answer.
Locked bootloader means it can only boot sony signed kernel
NO CUSTOM KERNEL NO ALWAYS ROOT
Unlocked means it can boot any kernel made for that device
You can always have root and have custom kernels
You can also get CM and all new features
The rom for locked bootloader can work in unlocked but vice versa is dangerous

NO, bravia won't work and this is the only thing i miss from locked bootloader.
As far as i know DRM stand for Digital rights management, so you can't download music info anymore. But there are many modded walkman apps can do that.

Yes. That I did, on older stock ROM, ST26i_11.0.A.3.28_WE. Lost root after upgrade to latest.
Downgraded, prefer have root than latest ROM however speed is about 15% higher on new ROM, must be better kernel and libraries.

why would u want to downgrade? u can have root access on every ROM even if your bootloader is locked.
So for unlocked bootloader just flash a custom kernel with "autoroot" function. Once u flashed that kernel, u will have root access after reboot.
For both locked and unlocked bootloader this tool from b1nary should also work...

As the name suggests LOCKED BOOTLOADER means the bootloader is locked and cant be accessed, so you can't install custom kernels as it is locked with the kernel by Sony itself......yes you will lose your DRM keys,you cant use trackid and the download music info which are somewhat pretty useless for me........those were such small sacrifices so you can access the vast open world of modding your phone.....hppe that helps.

Hi,
I wanted to root my phone, but it has a locked bootloader. I looked on a couple of turorials, and flashed a kernel. After that Phone, messages and all media apps disappeared, and errors came such as Keypad stopped working, and Android stopped working and stuff like that. And i couldn't root. So i want to know how to fix this how to unlock the bootloader.
EDIT: I fixed the apps by updating through PC Companion. Now i just want to know how to unlock. I've unlocked it now so i guess that's all i wanted.

No that would brick your device.
But: If you relock without DeviceKey probably no one will ever notice that various DRM features dont work any longer. I unlocked all my phones (most of them without DRM backup) and never noticed any problems.

i think best sultion is flash new ftf the kernel and sell it in that condition -.-* how much i would get for it ? screen and back have no scratches.... just the frame just some marks ... what would be acceptable ?
Wipe the phone and fully reflash it. The fingerprint sensor should work without drm keys.

Not possible. Locked bootloader = 100% stock Sony signed firmware only.
Lack of DRM keys arguably doesn't matter that much once it's out of warranty, but some DRM features are noticeable, like low light noise reduction for the camera.
You should make this information clear when you sell.
