[Q] urgent help!! regarding 4.3 root and bootloader

I had already rooted my z1 when on 4.2.2... But now the 4.3 updates removed the root... Unlocking bootloader ia only option as far as I know.. So I want to ask is..
A) if I unlock bootloader will I loose xreality engine? If yes how do I save that from not happening..
B) is there a "stable" way to install CWM recovery amd not unlock bootloader..? Is there is.. Will mybstock features be affected such as loss of xreality n DRM keys?
C) is there a way to unlock bootloader without looaing DRM keys? If so again will I loose the z1 features?
Please help..

A) if you unlock bootloader you WILL loose xreality. To get it back restore backed up TA partition. You can't have unlocked bootloader and xreality at the same time. Here is a video on how to get full root on 4.3: http://youtu.be/1aq9YTlfCgc
B) Yes you can install the recovery on any rooted Xperia Z1. You don't need an unlocked bootloader to be rooted.
Here are some more explanations if you are confused http://youtu.be/l78p_2ShPS0
C) You will always loose DRM keys when unlocking but you can back them up before unlocking to restore them later

Out there are 2 ways only how to root your Z1, both are for Locked Bootlader. 1 best way is here step by step, page 2, Post #16 http://forum.xda-developers.com/show...2588331&page=2 or NUT method here http://forum.xda-developers.com/show....php?t=2572988
..and what @shem2409 said it's all right.

Hello!
I've heard somewhere that if I unlock my bootloader that Mobile Bravia Engine won't work, is that true?
Thanks in advance

Apparently yes it is

You can preserve your drm key before and restore if ever you return to stock.
Plus if you look in the development section, I believe there is a guide to getting it working on unlocked bootloaders.
Xperia Z

If you havent unlocked your bl yet, you can backup ta partition before proceeding to unlock. After you unlocked you can simply restore ta parititon.
Be aware, for backup you need to be rooted your phone. And rooting not possible without unlocking the bl on the newly versions .569 and .101 (yet)

If you have unlocked bl nd did not backup ta then there is no chance you can get back drm keys bt there is a way to install bravia engine search in the forum.

There's no way to get back my drm keys??
So if my phone broke, I can't relock my booloader and send it to RMA?

Just one more question..
If I relock my bootloader, without restoring TA partition (drm keys), will Mobile Bravia Engine 2 still work?

No. No DRM keys means no BE2.

Its your choice
If you want to backup your ta you need to downgrade
If you are not bothered, just unlock

if losing Warranty is not a problem to You then Yes, it's the quickest way. Doing this you will be unable to do a Backup TA so your DRM keys will be lost forever with the warranty.

I unlocked on 4.3 and Camera, Track ID working. X-Reality turn On and Off but I never, even when I was stock, saw any difference. So if you want unlock on 4.3 (FW .136) it's ok.

Intact DRM Keys?

Hey all,
I just bought a used Z3+ and was wondering if someone could look at the following screenshot and tell me if my DRM keys are 100% intact and my bootloader has never been unlocked. I'm having a hard time figuring it out because after the first three, all other screenshots I've found have more [Key Ok] [Active] things than mine does. but, they are also for other phones. I'm used to phones without DRM, so I want to make sure I've got everything as intended. Can anyone compare to their Z3+ who may have never unlocked it and see what they think?
Thanks for any help you can provide!

i am 100% sure your DRM key is working
Right now z3+ don't has ROOT without unlock Boot loader
That mean it can't backup TA partition and can't restore DRM key
So this phone NEVER unlock Boot loader.

Got unlocked bootloader without possible root (5.0.2 28.0.A.8.266 firmware E6533 (z3+ Dual)). Used flashtool before unlock and saved S1 Dump in Advanced menu. Is it possible to get DRM keys from S1 Dump and restore bootloader lock?
Or my DRM keys now lost... ?

TA-Backup

Hello,
does someone know if a TA-Backup (and restore) would be possible, assuming there will be a method to root the XP with locked bootloader?
Regards, DiLeon

Yes, I know. Already did that in the past with my Z1c, Z2Tablet, Z3c ... But somewhere in the Z5 forum I read that it won't be possible, even when geeting rooted with a locked bootloader!? So maybe Sony changed something regarding TA partition and/or DRM storage?
