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.

[Q] Unlocked bootloader : Disadvantages?

Tried searching, but didn't find a clear answer to the disadvantages of unlocking bootloader for Sony Xperia SP.
Am really interested in unlocking bootloader, mainly coz I am a fan of CyanogenMod ROM's.
If an when CM arrives for SP, I will have to unlock bootloader.
If some doubts are cleared, will unlock it right away. May be.
Few questions, simply answered would really be appreciated.
1. We lose DRM is sure, but can we manage to add DRM keys back on unlocked bootloader?
2. Do we lose Bravia Engine 2?
3. Do we lose front camera?
4. Any other disadvantages? Or something I need to know?
Thanks!
1. Yes, backup TA: http://forum.xda-developers.com/showthread.php?t=2292598
2. Yes (unless you follow step 1). I prefer not having bravia engine because I noticed it made pictures taken by our camera look a million times more noisy
3. Well that's just a weird thing to lose... No we don't
4. Not really... Apart from the warranty void stuff of course
Not sure if you need to unlock bootloader to install CM though. If they made it work with stock kernel then you won't need to unlock the bootloader, if it only works with modified kernels then yeah you have to unlock
Unfortunately I did root my phone and unlocked bootloader without paying much attention to backup TA partition and possibility to lose Bravia engine
I should have done more reading instead of rushing to root my Xperia SP
can I know what is DRM keys that have been lost ?!! and if i relock bootloader will I restore Bravia engine.
also if Bravia engine is lost, how come i still can select it in Settings --> Display
is there anyway to test if it is there or not?
Thanks.

Yes bravia engine is lost
It still appears in settings but u will find the difrence in pictures that the bravia engine doesnt work after unlocking bl
Heres the thing guys, I unlocked bootloader on My V and J and still found Bravia working on the albums, I did not backup TA or whatsoever.
Its just placebo that it will be gone. I unlocked bL on both V and J because warranty is gone after a year.
The bravia engine only makes photographs look better on the phone. Sometimes think Sony chose less bright screen hardware just to make BE look good.

Hi!
I think you will find an answer of these question in this thread: link
1.Yes, you can restore the DRM keys if you made a BACKUP! Just flash stock firmware before you do that.
2.Yes, but thats only counts for stock rom.It works fine on custom roms.
3.No.
4.I dont know. My bootloader is unlocked and I have no issues so far.
I hope that helped!Press thanks if it did!

[Q] Explanation needed.

Hi,
Guys I need your help to understand this whole root thing and etc.
I do have Xperia SP software version 12.1.A.1.201.
I would like to root it. But to do it I need to unlock bootloader. - Fine, can do it as my status is YES.
but I don not want to loose DRM keys.
If i understand correctly first i have to unlock bootloader and then lock it again (to keep warranty) but first I need to root my phone to keep DRM keys.
But on my software i can't first root it and then proceed with bootloader.
Is there any method to first root the device, then unlock bootloader and keep DRM keys?
Sorry if this sounds stupid but I don't know where to start with it.
Thanks

Some [Q] about Bootloader Unlock [Xperia T]

So I want to unlock my phone Bootloader and install a fresh AOSP 4.4
Mine current android version is 4.3 Jellybean ( 9.2.A.1.199) and on the sony bootloader unlock site when I insert the dial number it says "Root status ...... Allowed "
I rooted it today ( havent installed recovery buy I can do it later)
My questions :
Can my phone brick while trying to unlock the bootloader?
Do I need to download the latest version or the 4.1 version of android ?
All this I'm doing 'cus my 1 year warrantly has ended today so Why not ? :good:
Don't think the bootloader unlock procedure has much risk of bricking your phone... especially if you use the official Sony Bootloader Unlock method. But you may want to read up on backing up your TA before unlocking the bootloader.

I'd also suggest backing up your TA first. It's all in here: http://forum.xda-developers.com/showthread.php?t=2292598
If you unlock your bootloader, you lose your Bravia Engine. You can get it back when you lock bootloader, but only if you restore your TA. If you don't have this backup, BE is most likely lost forever.

I've done backing up my TA keys ( done the dry restore to make sure )
So Now I only need to unlock my bootloader ?
Still one question :
Can I use my current version of android 4.3
EDIT : Unlocked the bootloader , put rom , gapps , wipped WORKING AS A CHARM
Thanks for the help !
And if I would like to restore to stock do I need to relock the bootloader ?

Nice!
If you want to get your phone back to stock, just flash a stock FTF. Flashtool does not require the bootloader to be relocked for that.
Unless you mean "stock" for warranty purposes, or selling the phone... then I guess I'd say yes to relocking the bootloader, after flashing a stock FTF (and also restoring the TA, of course)
Thanks 4 The Info )))

[Q] Is It Possible To Backup TA On Z1 Compact (5.0.2) Without Rooting?

[Q] Is it possible to Backup TA on Z1 Compact (5.0.2) without Rooting?
The title says it all. And I don't want some "Smart-ass" to tell me it won't make sense, because you know what DOESN'T MAKE SENSE. Having to back up DRM keys before rooting not to lose it, and the only way to back it up is to ROOT.
If you know another way to back up DRM Keys without rooting first, please tell me. Thanks.
EDIT 1 : I can't root without unlocking BL because of my Firmware version. 14.5.A.0.270

1st: You back up drm keys so you wont lose them when you unlock the BOOTLOADER
2nd: NO you cant back up the DRM Keys without rooting (you cant interact with the system's partition if you dont have root)
3rd: Try Kingroot to see if it works,( download it, install it and press try)
4rth: This is a xperia Z thread not a xperia Z1c
PS: Why dont you try flashing another firmware?

OK so to root, I most likely have to "unlock" which makes me lose DRM keys and that's what I wanna do before "unlocking" which is ridiculous. The only solution I know of is that I degrade down to Kitkat firmware so that I would be able "Root without unlocking BL". Or if you know of a method that makes me root without unlocking the BL at this version it would be better.

How to root Xperia Z4/Z3+? [Marshmallow]

I just received a Sony Xperia Z3+(E6533) on stock Marshmallow 6.0 and I've looked up how to root but only got ways to root while it's on Lollipop. Is there anyway for me to root on this software or downgrade from Marshmallow to Lollipop on this phone?
You can also root your phone while on MM. You can unlock the bootloader, flash a rootable kernel followed by a recovery and than flash the SuperSu zip. No problem.
But it is not recommended to do so, because you will loose the DRM keys/functionality when unlocking the bootloader. And once the keys are gone there is no way to get them back.
The better way is to downgrade to LP (e.g. .266), backup the DRM keys (TA Backup) and proceed with unlocking the bootloader and rooting the phone.
That's also the way I did yesterday, when I got the Z3+.
And of course you will have to read... a lot...
Thanks for the heads up , I've been trying to figure out ways for my specific model all morning and last night.
So to downgrade I'll just unlock the bootloader first then get a Lollipop firmware and flash using flash tool then do the other steps such as getting a rootable kernel and so on?
No, that is not what I wrote. Before unlocking the bootloader you will have to flash a LP firmware assumed that you want to backup the TA partition with the DRM keys first. This can only be done under LP.
I think you will have to read a little bit:
How to root Xperia Z3+?!
iovyroot - (temp) root tool
[Rootable Kernel SXZ3+ IVY/IVY_DSDS Marshsmellow ] [32.1.A.1.163]
What are the issues if we loose Drm keys? Will it affect non DRM normal contents? Or will it altogether disable Netflix or any other apps using Drm or other encryption?
You may have a look here:

Why don't create a guide?
