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.

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.
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...
I have now successfully relocked my bootloader and returned to stock ROM with my Acro S. I used the instructions and relock-files for Xperia S found here: http://forum.xda-developers.com/showthread.php?t=1527159
It´s good to know that it´s no problem to return to stock and a locked bootloader. I updated via Sony PC Companion so everything seems to be OK.
so which FTF file you use?
there is no FTF file for arco s ... what should we do?

The TrackID-app works just fine, or what else do you mean by checking Trak-ID?
when you unlock bootloader you lose DRM keys, and some software installed on the phone stops working, i.e. trackID.
And "share location" in the SMS app will not work anymore once you unlocked the bootloader.
thanks...

By using the Xperia S ftf, don't you lose access to your SD card?
It's no use!
Because when you unlock bootloader, you must go to SONY net to get unlock code.
SONY know you unlock bootloader!
When your Phone get something wrong and send back to SONY, they will say no guarantee. Because you have unlock bootloader.
Do you have see the instruction at SONY net when you unlock bootloader?
So what advantage when you unlock bootloater and relock it?

no because after you flash the relock ftf is only for the bootloader, you still have to flash stock firmware again or else it won't boot

i think he knows that already, he probably wanted to switch back to stock rom from cyanogenmod, and just happened that there's a new rom out but nobody posted one that's for his region, so he needed to use pcc.

I have unlocked my bootloader and then relocked it as stated above. But my TrackID app works just fine apparently, so that doesn´t seem affected. But I cannot send my location within the SMS-app, that´s the only thing I have encountered so far with stock-rom after relock.

Thats not even true. If ur sending in ur phone for warranty with unlocked bootloader. Sony takes a fee to restore bootloader. Else just relock bootloader urself before sending it in. So plz stop spreading lies and plz use a brain before posting.
Hi, my Acro S has an unlocked bootloader. If I flash this FTF no brand file. Will my bootloader will be locked again? Because as you've stated that the file wasn't modified in any way. Correct me if I'm wrong . Thanks.
I did search the forum, and found methods for Arc, but none for the Arc S.
Is there any way ?
Also what are the disadvantages of losing DRM? Read somewhere TrackID and Timescape won't work. I can live with that. Anything more ?
timescape work fine in my lt18i with an unlocked bootloader
They use the same methods.

Official method only works for generic, unbranded phones. If your phone was purchased through a carrier, its bootloader cannot be unlocked.

SETool1 doesn't support the arc s (LT18i), only SETool2 which requires hardware and paid credits.
Frequently Asked Questions about the bootloader:
In short, with the available methods, i'll lose DRM on my LT18i if i unlock the bootloader, right ?
I want to return the device to stock and read on the sony dev website you have to flash a firmware but I do not see the Z5P, is there any other way?

Is there a reason why you need to relock the BL? According to Sony, there is no way to restore an unlocked BL.
Q: If I change my mind later on, is there any way to restore my device?
A: No. Once you have unlocked the boot loader, you will not be able to revert the device back to a locked or original state or restore the DRM security keys. You can however use the Flash tool for Xperia™ devices to flash a generic Sony ROM, although it will not receive automatic software upgrades.

You can relock it using flashtool. Just choose Xperia Z5 when the device window appears. I've already tried it, works like a charm.
Not sure if you can relock it without the back up drm keys. Since there isn't a backup program yet I would assume you've already lost the drm keys. I'm afraid you won't be to revert back to the same. Camera quality and x reality will be affected.

Some important things before you attempt the relock:
The DRM keys will not be restored after the relock.
You have to reflash the entire firmware or just flash the stock kernel before relocking the bootloader.
The phone should be on stock kernel, if you try to relock it with custom kernel the phone might brick.
Click BLU in flashtool and follow the instructions.

Turn off the mobile.
Press the BLU button in flashtool.
Press the volume down button of your mobile and connect it to the PC.
A pop up window will open, select Xperia Z5 (Z5P is not listed yet).
Another window will open, if you see Relock, press it, the bootloader will be relocked.
Let the process be over, then restart the mobile.

I had to unlock my device's bootloader to downgrade it to marshmallow because of the WiFi issue in Nougat, so i did it and didn't backed up the DRM keys(i didn't knew i am supposed to do it. It wasn't mentioned in the tutorial i was following or i missed it). Anyways now i am on marshmallow and i am unable to update it VIA xperia companion. It complains that bootloader is unlocked. Now if i lock the bootloader will xperia companion will work ? What is the affect of the lost DRM keys ? And if anyone knows the WiFi issue is sovled or not ?
