[LT18i] unlock bootloader without losing DRM ? - Xperia Arc Q&A, Help & Troubleshooting

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.

As i know you can't unlock your bootloader at the moment without lose the DRMs.

You lose the ability to use things like Trackid

Read from somewhere, that test point method is not supported on Arc S, but is supported on Arc. Someone tell me more.

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 ?

Xperia Neo Unlock Bootloader warranty

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.

Bootloader unlock allowed Yes after official ICS update

I have Xperia Arc LT15 with GB 2.3.2 before & found out using *#*#7378423#*#* that I cannot unlock bootloader. I was disappointed as I was using CM7 & CM9 on my HTC Wildfire & ZTE Blade. So I decided to go with the official ICS update. But when I checked after the update it says "Bootloader unlock allowed : Yes". So the question is can I unlock bootloader now & install CM9 or other custom ROM using this (http://wiki.cyanogenmod.com/wiki/Sony_Ericsson_Xperia_Arc:_Full_Update_Guide) method?
Yup, you can unlock your bootloader.

Testpoint it and dont loose drm data. Easier to relock also.
Typed down from the sky with sexy LT15i
+1 for the testpoint method of unlocking. It is the safest and best.
Testpoint method advantages:
1. You keep DRM keys
2. OTA updates with S1tool unlock, I'm unsure?? It is safe with SEtool (paid) testpoint unlock, coz I've done an OTA myself after getting SEtool unlock done by jinx13.
3. No warranty loss.
4. Even carrier locked phones can be unlocked, although this is usually a paid service using SEtool instead of S1tool.
Sony official method might be free, but it is terrible because:
1. You lose DRM keys
2. You could wind up with a bricked phone if you are on an official Sony rom and install an OTA update.
3. It borks your warranty.
4. Carrier locked phones can't be unlocked at all this way.
Bootloader unlock allowed : Yes
it mean you can unlock your phone
Whaaaaaat?!!nofake? Updating the arc with official ics unlock bootloader?! Do it works for all the arcs?
Was it a piece of luck?
Plz respond quick I using jj's rom so I wont test before I ll be sure that it works...

[Q] Need Some help about Unlocking and Relocking Bootloader(sony ericsson Xperia pro)

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.....

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...

Unlock bootloader not allowed, what to do.

Hi I was all prepared to unlock my bootloader, at the first step I learn that my bootloader cannot be unlocked following the sony official method.
Can I still unlock my phone and how.
It is running like a slug now that I've upgraded ti IC.
Cheers.

Bootloader & SIM Unlocking:
PLEASE NOTE: The ONLY WAY to Sim Unlock your Phone is to PAY for it, so do some Googling and read which services have been recommended in the past.
- Know Your Android Bootloader - What it is and Why it Matters
There are three ways to Unlock yours, the Standard/Official method (For SimFree/Un-Branded Phones) which is explained HERE, (PLEASE NOTE! - You loose DRM when using the official method but not with the TestPoint) but if your Phone came from a Carrier then chances are (99%) you won't be able to use that method. There is a simple method of checking if you can or not which you'll find HERE.
Standard Unlocking:
Then there is the TestPoint method...
TestPoint Unlocking:
Two members - Alejandrissimo or Jinx13 offer a Remote Service which isn't free, but cheaper than anywhere else on the net, and when you take in to account you will also SIM Unlock and retain DRM using the Remote method it's worth it.

[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..

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.
