Hi guys,
I have bought a second-hand z2 tablet. Unfortunately it has the BL unlocked and no DRM keys backup. I flashed the last stock rom (firmware 23.0.1.A.4.44) keeping bootloader unlocked. I read that with KK update X-reality should work also without DRM keys, but this is not true for me. Is there any way to fix this problem? If I re-lock BL and after repair with PCC , can I solve it?
Thanks

Thanks for your reply.
I took a look at the post: honestly I don't care to have custom ROM or BL unlocked. For now
stock rom is good for me. Since lollipop is coming, I'll try to relock BL and repair with PCC, hoping Sony will remove the restrictions. Otherwise I'll try the procedure that you have suggested.

Hi, I just upgraded from ArcS to Xperia S, and bought a proper sim-free Xperia S. I did the test in the service menu, and it says Bootloader unlock allowed.
Now i'm guessing when you unlock, that you lose DRM keys and other stuff (like the Arc did). I only really want root, without losing anything that I can't get back.
What's the best method? Is unlocking the bootloader the only option open to me?
Thanks.
Hi CrazyPeter
Take a look at this threads:

I don't know if the DRM keys will be deleted or not. But I think while the Bootloader is untouched, the DRM keys also will be left untouched??

Hi everyone, wonder if you can point me in the right direction.
I'm currently on a custom rom with an unlocked bootloader and I wish to go back to stock including locking the bootloader, from what I've found out so far this is what I need to do: -
Flash original ftf
root
flash TA
reflash ftf to lose root
Now back to stock with "Bootloader Unlock Allowed: Yes"
Trouble is I can't find how to go about restoring the TA partition from my TA image so if anyone can explain what software I need and the steps I have to take I'd greatly appreciate it, thanks.
You can use the same tool that is used to backup the TA partition (read the FAQ in the 1st post):

I didn't know that you see as I used the Doomlord root exploit before the other methods were available, thanks again.
Edit: Thanks again, I'm now back to stock with the service page reporting "Bootloader Unlock Allowed: Yes"

Sorry for high-jacking this thread, it however loosely fits my problem.
When I got the Z2 I was, in all honesty quite quick with rooting and swapping the stock Sony ROM with Cyanogen. So quick in fact that I didn't bother for two seconds to actually perform a backup of the system beforehand.
So my question is this - is it possible (given the fact that DRM and such will be lost for all eternity) to revert to stock rom without the backup?
If so... How really? (couldn't find anyhone so stupid on here to do the same rookie misstake as I did so no answers was found while scouring through the forums...)
Thanks in advance, and yet again, sorry for high-jacking the thread.

you can revert to stock using flashtool and a ftf of your choice, also you can use flashtool to relock your bootloader

Thank you for a quick reply - forgot to add a question, what happens to the phone WITHOUT the DRM keys? What will I not be able to do - that i presently can with cyanogen or non-f***ed-up-stock-ROM?
Thanks!

nothing is affected by your drm keys weather they exist or not in 4.4.2/4.4.4 xperias they are simply used to check if you have modified your device ie. bootloader unlock (relocking doesnt restore your drm keys)

Well as I already figured that I messed up any warranty, that's no issue for me, so really thank you. I was hoping that I could restore to original stock rom to be able to properly use the camera and noise-canceling headphones. Seems like it then. :good:
Yet again, thank you!

X-Reality and Noise canceling not working is a bug in certain firmwares the camera not working is a myth
What will I loose if I unlocked my bootloader? Is there way to root without unlocking it? Or its still not possible? Any alternatives so that I will not loose any important features in my Xperia z5c? I'd like to use my Xperia z5c in full customization. Thank you in advance for answering.
Almost nothing, practically all custom kernels come with a DRM fix. (Normally you would lose some extra Sony features in sound, camera)
The only thing is, you won't be able to restore it. There is no way of rooting without unlocking your bootloader.

Sony warns you that unlocking BL voids your warranty.
But I've send in my phone after unlock BL and got a new one without any issues.
I would recommend to flash stock rom before you send it in for warranty.
Better is hard to say, it depends on what you want to do. If you want root access you'll have no other choice.

Hi,
My Xperia X is already upgraded to Nougat stock, no root, bootloader locked. What would right steps to keep DRM keys, root, (unlock bootloader), to install custom ROM Xperia Poison?
TA backup seems to not support Nougat, but I saw thread about Kernel with DRM-fix and Xperia Poison has also built in Kernel with DRM-fix , is that means if I'm not able to backup DRM keys I still have full camera functionality?
Thank you
Answer: I downgraded to MM to get DRM keys.
Please help
I also want to install poison rom. On dual sim X. Please enlighten us Deva. Thanks
Please enlighten us devs.please

If u unlock your BL u lost DRM keys forever. My ROM and DRM-fix is only hack (emulating) to system thinking what keys is ok.
To back up DRM-keys (TA) you need Downgrade to MM and use Dirty cow exploit.
After u sucess U can unlock your BL and install any kernel/rom/recovery.
Can someone explain exactly which keys the phone has, and which features they provide?
thank you so much sir

Really my main hangup with the phone, curious if I should wait until a temp root solution comes out so I can back up what will be lost.
there is no solution as for xperia 1 and 1 mark 2 also to back up drm keys.
If someone does an unlock, can they please report which DRM features will be lost?

I thought the mk2 had a temp root solution where you could back up the drm, and restore once the bootloader was unlocked.

Nothing confused about it.. You ask if there is a way to back up DRM KEYS the answer is no but you can repair them when you relock the bootloader and repair with xperia companion.. Thats the only way.

Ah OK, will the phone stay rooted after relocking the bootloader? I assume this still voids the warranty?
