hi gyus, i have a question...is there any way to make BE and music info work with unlocked bootloader? I want to unlock my bootloader but i dont want to loose these things, thx for reply
There is a thread somewhere in the developing section (dont remember its title)
But it shows you how to backup and restore your drm keys after unlocking your bootloader (drm keys = what makes bravia engine work)
Some techy info
So your TA partition is the partition with your drm keys, unlocking your bootloader wipes this partition along with your DRM keys
So putting the keys back in the partition afterwards lets you keep bravia engine
You cant use other peoples drm keys otherwise it will brick (break) your device

Hi Guys,
i have read in a german forum, that its possible to get DRM Rights back if you have your Xperia 2011 device unlocked with the SE DEV Key and fastboot..
You need the programm "s1tool" and have to run the "restore" button!
Is this right?
Thanks in advance
edit // I have uploaded the s1tool so you can check it out
I will look into this tomorrow.. Might be handy

I've tried. No, the restore button doesn't restore DRM key. It only relock bootloader.
Hey,
I would like to unlock my bootloader. In all the guides I've read, it says I will lose all my data.
I was wandering whether its possible to perform a Nandroid backup before bootloader unlock and then restore that data after bootloader unlock.
Could someone please tell ne if its possible?
BTW, I use a Sony Ericsson Xperia arc.
Thanks
Testpoit it. Its easier and you dont loose anything and not the DRM keys too. Easier to relock it too, as original

How would I relock my Bootloader?
Is unlocking a bootloader the same as making it simlock free?
Sent from my Xperia X10 using xda premium
No. Bootloader unlocking is not the same as sim unlocking. Bootloader unlocking allows you to install custom roms to your phone.
Hi, everyone
I have my experience about unlock bootloader, I have unlocked bootloader via official Sony method, when DRM lost, I decided to relock again, flash stock FW via flashtool and repair via PC Companion, after that DRM has been recovered.
So, I've tried to unlock bootloader via testpoint using S1tool, after unlocked, flashed custom kernel and ROM. DRM still lost
Any solution ?

When you unlocked via Sony method, you lost your DRM forever . There's no way to recover it. So, I'm pretty sure you're mistaken about the recover of the DRM keys.

When I claimed warranty, I relocked, repair via PC Companion, DRM worked ( transfer music via media go works ) then when I unlocked via testpoint, DRM LOST !! IT'S IMPOSSIBLE

Never heard of a way to restore the DRM Keys after unlocking via official method. There's some thread that explains this? I've read from many sources (xda, setool) that once you unlock the official way, you lost the DRM keys forever.
Maybe when I repaired via SUS, DRM recovered

That's not possible AFAIK. I've searched again and the only thing I found is: You lost your DRM Keys.
DRM Keys are stored in a trim area and when you unlocked with the official method, they're erased. SEUS or SUS can't restore.
At least that's what I've read about this.
Btw, I sent my previous lt18 to Sony warranty without the Keys and they returned a new one. So, the fact that they didn't complain, doesn't mean much. But let's wait for more experienced members opinion. That's all that I know about this.
Ok thanks, I'll kepp my warranty as well

I've read it now. Let's focus some points:
No.. Working Music info download or Track ID does not prove that DRM is recovered. There are workarounds to make stuff like FBMedia like or TrackID work..

Yes I know what you are saying.. Like I said using your method does make em work(there are other work arounds too).. but the DRM is not recovered. The system is just fooled..

The only post that supports that might be possible is this one (but, in my humble opinion, this is just a bogus information):
Some info from MDPI device forums.
They have been saying, that just relocking bootloader and unlocking via test point method recovers DRM. No need to reflash ROM/kernel or anything else. Neither you need any Walkman apps or stuff.

I strongly believe that like heinrichkaiser said in that thread: This method make the apps work, fooling the system, but don't restore DRM.
They even linked some topics in the setools forum, and no one (even the_laser) could confirm that there's a way to restore. That doesn't mean that it's impossible to make some functionalities work after the loss of the DRM Keys, as you can read here:
ok here's the simple steps after unlocking bootloader.
1. Uninstall the old TrackID (its a system app so u need root)
2. Download the latest TrackID on android market (the silver one/not the old blue)
3. Backup the FBMusicLikes.apk/Music Likes app
4. Uninstall the FBMusicLikes.apk/Music Likes app (its a system app so u need root)
5. Reinstall the FBMusicLikes.apk/Music Likes app
6. connect to net and try it, its now working again.

You still can't get DRM back. It's gone from the phone!

hi bros/
my boot loader is unlock and my bravia engine not work.if i close my bootloader does it work again in close bootloader?
or
i lost my BE for ever?
Depends on what device. Typically it is gone once you unlock. There is a mod to get it working once you relock but it only Works on certain devices.
Sent from my Sony Xperia™ Z
my device is acro s/wich mod can be coming back that to my phone?
that working for once time?
Yeah, sad also. If Sony is really developer friendly they shouldn't have done this (DRM keys thingy).
Try this mod: http://forum.xda-developers.com/showthread.php?t=2068225
This will restore download music info & Bravia Engine when relocking bootloader.
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
Sent from my C1905 using xda premium
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!
