Xperia Arc LT15i
Rooted/Unlocked BootLoader
Jellybean - FXP132/CM10

[Q] DRM still lost after unlock via testpoint

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..

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.

Why the bootloader is locked ?

I don't understand.
I bought my ZL on Amazon.
This is a naked version not a version of an operator.
Yet he blocked bootloader.

Every bootloader is locked. What matters is whether its 'unlockable' or not. Does the bootloader unlock allowed say YES or NO in your case?

Did you root your phone? When rooting the value changes to NO, but when you flash the original ftf it returns to yes.

To correct this, after rooting with locked BL, delete the file "libservicemenu.so" using a root explorer. U shall find it in: "data/data/com.sonyericsson.android.servicemenu/lib". I read about this fix on the XZ rooting thread and it works on my ZL :good:. Hope it works for u guys too.

Hey will unlocking the bootloader with the unlock tool void the "Hardware" warranty?
if you relock it, I think sony would know since you unlock it through their servers right?

I'm afraid, yes! I've read about sony refusing to honour warranty to many Xperia S users for repair of screen "yellow tint" issue owing to their unlocked BL status. Even if you relock the BL you still won't restore the sony DRM keys to the "TA" & that's probably how sony service guys know about unlocked BL status, of course beside the record on their website (regarding unlock code request).

You will never be able to unlock the bootloader on that phone, unless your carrier can give you some kind of code to change your unlock status (not sure this is even possible).

The BL is different, if it came from O2 then chances are you cant unlock the BL.

So there is no chance? It worked with xperia arc and omnius. Costs about 15$, that would be ok. But will it work with our z1c in the near future? Or is it just "luck" to find an exploit?

Well nothing is impossible, but it isn't likely as it requires a bootloader exploit. Realistically it isn't going to happen though, unless some smart people devote a lot of time to it. The most likely scenario (using test point to gain more software access) would require hardware tampering.

Hello Mentalghost,
Unfortunately there is no way to unlock the bootloader when the status is "No".
Have a great day, cheers!

MentalGhost, where did you purchase your phone? This phone isn't sold by any carriers in the USA, to the best of my knowledge, so the bootloader shouldn't be locked.

Bought in UK where I am not in USA. Might take back to shop where bought from and see if got any others in lol
Or wait for locked bootloader versions or someone makes modded version with unlocked rom that is been modded like one where you install modded that is unlocked install and then can unlock bootloader did in xperia s I use to have was a modded rom that was originally saying bootloader unlock no and added new Base rom and then said bootloadr unlock yes maybe this will happen on this phone in time or locked bootloader kernels and rom come along

I'd recommend to anyone that is still able to return a Phone to do so because I think you'll find you'll be waiting a long time for a solution.

Plus, there will be no solution. The reason why Xperia Arc S and other 2011 Xperias worked with testpoint method was because of that there was a big security flaw in the security of the testpoints nand access, but those flaws have been fixed in newer Xperias and newer 2011 Xperias also.

+1 It was coming to that realization that I sold my O2 locked Z after 6 months to buy an unbranded Z1 Compact. It worked out cheaper too spending hundreds of pounds up front for my Phone with the added bonus of having access to all of it.

What happens if you still follow the instructions on how to do it? I didn't check if it was allowed and I'm stuck in bootloop and I can't flash via flashtool,

Is there any way to relock the BL?

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?
thanks,
AC

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.

Relocking Bootloader
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 ?
