Hello,
Is it possible relock bootloader + restore drm keys?
I need to do that, because i want sent my device to service.
Is it enought or should i do something more?
How to do that?
Thank you
You can relock your bootloader through flashtool and you can restore your DRM Keys only if you did a backup before unlocking.

Okay.
After doing that, can they recognize that bootloader was relocked and DRM keys was restored?

I think they - through sony (as you requested a unlockcode for your imei) - will be able to tell it has been unlocked.
But I sent my device for service multiple times, I re-locked my bootloader and flashed stock, without restoring drm - never heard anything about it.

Hi, how can i back up before root/unlocking boot loader? i want a backup incase i screwup
You don't have to unlock bootloader. Use 'Gingerbreak' instead. It's very easy and no harm to your data.
so how do i back up?
Like incase i want to go back to factory reset.

So you only need Gingerbreak and then fastboot (Bin4ry tutorial)?
For getting root gingerbreak alone is enough. If you also want an unlocked bootloader (not necessary for root anymore) you'll indeed get some extra work.
I cant hold myself back to share my thoughts about general hysteria about unlocking bootloader and therefore losing DRM keys. While I understand, that many users are pissed off, there are some points to consider before putting blame on Sony:
- losing DRM keys in no way cripples or disables hardware in your phone. DRM keys protect some "exclusive" functions that Sony offers to users of its Stock ROMs, mainly Camera and Display Enhancements.
- Its up to you, to decide whether you want to go on with pure Iron and add functions you want, including any Image enhancements you want to add on top of raw data processing, or go full blown Sony with all bells and whistles.
- One should be clear, what he needs unlocking bootloader for. Root only, or Custom ROM/CM.
- even without "artificial" enhancements to Camera and Display, Z3 (and Z2 as well) is impressive piece of hardware and it will be pleasure to run swift clean Android/CM on it
- I blame Sony of course for not telling users the full story behind unlocking bootloader. It would be fair from Sony to offer re-flashing Stock including DRM to users, who unlocked bootloader before they knew that they will lose certain software functionality.
Howgh.
For me it's more about losing the warranty

Well, that's quite obvious It would be awesome to have hardware warranty separate
I'm using remote play so I do not want to loose my DRM keys...
You can root with giefroot (works in some versions) backup TA partition and then unlock.

The point is that giefroot works seldom. I cant use it, at least not now, simply doesnt work on certain models. Having TA/DRM backed up is good, but only for eventual reflashing stock. Maybe in future there will be some use for your DRM keys in CM or other ROM if there will be app requiring it or somebody makes Sony apps working..

If you root without unlocking the bootloader, do you still lose the DRM keys? I use Remote Play as well and that would really suck to have to choose between root or remote play and usable pics from the camera. I'm on a D6616 (T Mobile), so rooting doesn't work with the existing method yet, but hopefully it will soon.

No. And after you can back the TA partition up and restore it whenever you like. The TA partition contains your DRM keys.

Fantastic! I'll just sit here and wait patiently for D6616 support. Thanks for the reply.

I'm with you. I'm just going to creep xda till somthing amazing happens lol.
4.4 roms would be great imo, dont know why noone pays them attention
So from what I gathered you can root first, backup TA which includes the DRM Keys, then unlock bootloader?
Then if one wants to restore the DRM keys, restore the TA DRM backup and lock bootloader? and the phone is back to stock with the super duper enhancements? Correct?
Someone kindly confirm the above as im looking to pick one up if there is a backup / restore option available?
I will be looking to purchase a UK model.
Thanks.

Before restoring, flash to stock first. And then restore drm keys.
How can you restore drm keys without root??? surely it needs block level access to that flash partition???
Anyway, only reason I want root is to re-enable r/w access to sd card, which apparently lolipop will have anyway

With plain root, what would i loose? The dilemma is loosing something special out of a special phone. And whats drm to be exact? Sorry for being such a noob. The last time i explored rooting and custom roms are back when i was using an r800i Xperia Play.

You will lose nothing. Unless you unlock the bootloader which will mess with the TA, from there then you'll lose Sony abracadabra magic image processing and low light camera performance. DRM = TA
DRM is unique for each device, if I were to give you my DRM and you restore it, you'll hard brick your device for sure. It's like an identity card or a car plate (hopefully you get the idea) DRM is the one in charge of the magic sony has. This bad boy is very sensitive, be sure to back it up if you want to unlock bootloader.
All in all, root doesn't disturb this bad boy in his deep sleep lol
Cheers,

Any chance that lifelog is affected by the loss of drm keys as well? It stopped tracking since unlocked...

Google Camera
Is the DRM for the camera only for the Sony camera? If I unlock the bootloader and use the google camera from the play store will it be worse than using the stock camera when it was locked?
Thanks Thraxzzz for the Idea, i now get it, i guess i was Looking for a General "need to know" thread here is the General but there's none "i guess" i have a full understanding "somehow" now. It wasn't this complicated back then when i still have my r800i, maybe someone should start a Sticky Thread about abbreviations and what must and must not. If i rushed in and unlocked my Bootloader, then i could have lost what i actually paid for from the beginning. Its interesting to start learning the do's and don't.
which app to use to backup ta (drm keys)?
It says
The app not computable with my device
When trying to unlock sim card
Thats becuse I'm rooted?? Or what ?
It doesn't work with root or so I was told; I had to return the device to stock to use the SIM Unlock App. I hate T-mobile for this.There is a thread on how to do that including relocking the bootloader before running the SIM Unlock App (that works perfectly). Once SIM Unlocked, you can reroot

I don't remember having to relock the bootloader... but either way you'll need to backup your current data to restore if you care about your data that is... unrooting will encrypt your data partition rendering TWRP unable to access it and locking the bootloader wipes your device.
Hi, I want to backup my TA/DRM key. However the "Universal (Dirtycow-based) TA Backup v2" seems not compatible with Android Nougat. It asked me to downgrade my device first. Is there a way to downgrade Xperia X Compact without unlocking it (or without losing the DRM key)? Thanks.

Just use the flashtool, you don't need to be unlocked to flash firmware.

Another question. My phone is showing up "Bootloader unlock allowed: No" in the Service Menu. I've already turn on "OEM unlocking" and "USB debugging" (
authorized, and confirmed all the necessary drivers were installed).
The "Unlock your boot loader" site is saying that "It will only be possible to unlock the boot loader for certain releases." Does that means I should flash another firmware with differnt region or Android version? I've already tried to downgrade my phone to MM again, however the issue still exists. Thanks.
P.s. I am able to get the unlock code from the "Unlock your boot loader" site.

If your phone says that is is NOT allowed... sorry, but it is not possible.
Even though Sony is happy for us to unlock the bootloader, if the carrier/operator (verizon, o2, virgin, etc) wants - these companies can ask Sony to stop the bootloader from being unlocked.
Sim lock is one thing... at least that can be removed. I have no idea why they would choose to prevent the bootloader from being unlocked.
Actually, maybe because in some countries the consumer laws are very good, so even if you root or something, your warranty still exists.
But if you cannot unlock the bl -> you can't root -> less device problems/bricks -> less money on repairs for the phone operator? (just an idea)
The first (used) Xperia X Compact I bought, it was carrier branded, and the bootloader was unable to be unlocked.
I talked to the shop owner, I chose the other device in stock, it was unbranded, I could unlock it

Thanks for your answer. Though it's a bad news for me. [emoji30]
Since it's impossible to unlock my device, can I just modify the FTF and flash it through the Flashtool? If it's possible, then how to modify the FTF file? I want to change the font into another.

No. If you've still got time to return it do so now otherwise your modding is going to be limited.
and keep all data/apps installed.
Is this possible?
Thanks

It's unlocking the bootloader that wipes your device. If you've already done that, rooting won't wipe it.

I understand. So its not possible to unlock the bootloader without wiping, correct?
And is it possible to go back (locking the bootloader) and reseting to factory default? Or do I lose something (like Knox on Samsung devices)

If you haven't unlocked your bootloader, you don't have a choice, you're going to lose your data. Yes, you can go back to stock and locked pretty much whenever you'd like. Just don't try to re-lock the bootloader if you have any mods. This is my first OnePlus device, but it sounds like the restore tool can be used to restore to stock/locked regardless of any mods you may have, but don't take my word for it, do your homework first.
Do a backup and open the bootloader, you only have to do It once, and then, you could root when you want without lose anything.
