[Q] How to backup TA, MAC and IMEI with unlocked BL?

Greetings to everyone
I have already unlocked BL & rooted my 4.3 xperia Z1 with CWM recovery installed... the camera and everything works fine
So, how to backup TA, MAC and IMEI with unlocked BL? I want to avoid any furthur losing possibility of them
Sorry If this a repeated question but I have searched a lot before posting this
thank you

You can't Backup your TA if you Unlocked your Bootloader. You lost your DRM keys permanently. You will not be able to re-lock you bootloader and you are not covered by your warranty. Sorry but you should read carefully before do anything.

Yeah, too late, you should have done this before the unlock....

Should be all fine but the safest way was backup TA first because if one day happen something on your phone you can't go via warranty.

You still losing your DRM keys so even if he does it's compromise, no x-reality, bionz engine and bravia.

This is not a problem, the FTFs will be upload here on XDA like for .290 and Custom Roms as well.

This is what we said already, the risk is if you brick the phone and the warranty will not cover that.

You don't have to avoid anything just read carefully everything when you try to do something. My advice is now to wait for the confirmed and safe way to root or update. In your position you already lost the safest way so I will root, update or flash custom roms to enjoy the phone but remember, it's your own risk and responsability.

Ive done the same, came from HTC.....so I will still have all tge features unless I flash say cm11 and try to go back to a Sony based rom?

Root with towelroot

Time ago I rooted with towelroot (.108, C6903). I totally forgot to get some information about the ta partition. How can I check it? If it's gone, what did I lose?

*#*#7378423#*#* from your phone dialer, go to service tests, then security, if there are entries in there and show the status of ok then you don't need to worry, you haven't lost your ta partition. What I would suggest is that you then go ahead to the thread about backing up the TA Partition and do it.

Simple rooting via Towelroot does not remove TA partition. It's unlocking your bootloader that will remove the TA partition. So if you have not unlocked the bootloader, then your TA partition is still there.

you can find a useful tutorial of using "flash tool" and how flashing .ftf files, here:
[25NOV][FLASHTOOL GUIDE] HOW TO for n00bies - G-FACE GUIDE
and here is prerooted and deodexed flashable 14.4.A.0.108 :
[STOCK][C69XX][4.4.4] Update to 14.4.A.0.108 [Root & XZDR][DE-/ODEX]
and I highly recommend you to read this very useful post by Great DOOMLORD :

Hi ! I am a new Xperia Z1 owner and want to root, unlock the bootloader and install a custom recovery so I can flash roms. I am on the new .108 firmware - any guides ? How do I do this ? Thanks for your reply in advance !

There's a thread that should explain everything you asked.. For root and custom recovery there's a really simple trick with towelroot (look for it), for everything else you should look here: http://forum.xda-developers.com/showthread.php?t=2439328

I've read it through already but it's for older firmware so I can't follow it... Is an option to root the Z1 whilst having the bootloader locked then backup Ta partition and then unlock the bootloader and install a custom recovery?

Look, you're right saying that's an old thread but you should just download the latest corresponding files (http://nut.xperia-files.com) and you should be done! Otherway Google "how to unlock bootloader xz1" or stuff you need and you'll find more recent guides.

[Q] Bad Camera quality after Unlocking BL

Hello buddies ,,
i have a very Bad Camera quality after Unlocking BL
and i didnt backup the ta partition

You can relock with Flastool. It does not restore DRM keys.

Well. Next time read it more

go to the cross device development, there is a mod on how to restore the good quality without the DRM keys.
it works for me, just follow the steps as they are.
(when u need to install a kernel with recovery on laters steps, install doom kernel via fastboot using flashtool)
hope i helped.

he lost his DRM keys, SO even with a locked bootloader the camera will still be the same as with an open bootloader.
he didn't backup his DRM, so he can't restore them after locking up the bootloader, your solution doesn't help.

It wasn't a solution I was just saying. I prefer to keep to LB. Try DRM fix thing. I have heard it good.

is it possible to take backup & restore of Xperia Z3+ DRM Keys?

Hi, Is it possible to take backup & restore of DRM Keys of Xperia Z3+? After bootloader unlocking, is there is any chance of getting back the warranty? After Unlocking bootloader of Z3+, can I get the official updates? (restoring stock ROM without rooting)
Can anybody help me answer me about these?
Thanks in advance.

First, you should not use your email as a username.
Second, there is no known way of backing up DRM keys, but you can re-enable function of those using DRM restore (search the forum a bit). You can always relock the bootloader using Flashtool (again, search xda or Google) to regain warranty and also to get official updates. You can also flash any firmware using Flashtool without the need for official updates.
Oh and don't open three threads for three questions and especially not in general section but in Q&A...

Yes, iovyroot allows you to back up your DRM and use it later to restore on locked bootloader, already done it and right now liking it so far. However, only 266 firmware is working. Other versions does not work.

I don't believe there's a single tutorial on how to unlock that doesn't mention this is a one way process and it can't be recovered.

I try one option
First I flash stock Rom on flashtool
Bootloader still open
I guess Drm key is lost
Thats really bad photo is not working
Bla Bla....

Unfortunately, as of right now, there's no way to relock the bootloader, and your DRM keys are lost forever.
You can try the custom kernel in the ROMs.. section, which includes a DRM fix, which maybe can restore some of the functionality of the camera.

Ooo really =( so please could you suggest me
Which one should I try?

A lot sure has changed since my previous phone (Z5 compact). Back then, simply flashing stock firmware automatically relocks the bootloader.
I'm surprised that's no longer the case.
Guess we'll continue to see little to no development of this phone until major breakthroughs.

I see you tried the DRM fix already. Try the boot instead from here: https://forum.xda-developers.com/xp...compact-16-january-2018-t3736068/post75377373

Does
fastboot flashing lock
or
fastboot flashing lock_critical
not work anymore?

There is no way to re-lock your bootloader once you have deleted the TA partiton. There are so many warnings on your way to unlocking that tell you this repeatedly.
You can use sToRm//'s Sony Xperia XZ Premium TWRP + KERNEL + ROOT + DRM fix/restore
app to enable your DRM again, then you can take pictures and everything is as before.
