Bootloader unlock unlock wath can be disabled,etc... - Sony Xperia T, TL, TX, V

Hi,everybody i'd like to make a info thread for who wants to unlock bootloaders.
We know we "loose" warranty,but someone did pay when phone had a hardware problem?
I backed up my TA partition so i can keep bravia engine.
Can we loose something else ?
I make that for me and others because i'm tired of crappy SONY frimwares x) and i want to officially unlock mine because i had no answers about kexec or unlock/bypass bootloader.
Thanks bro's

I am very unsure about your post but if you want to officially unlock your bootloader then just do it, why the need for this thread?

[Q] Rooting Xperia Z - Bravia engine..

I have heard that rooting xperia Z would lead to loss of Bravia Engine functionality and Track ID too, is it correct ?
I am thinking to root my phone.

It's all good now. If you backup your TA partition first before you unlock the BL you can flash the keys back and BE2 will work again. You can read the tutorial here http://forum.xda-developers.com/showthread.php?t=2234627

rooting isn't the problem, but unlocking the bootloader. luckily there is a way to root your phone without unlocking the BL, but keep in mind: you can't install custom firmware with a locked bootloader (only sony based ROMs or ROM-modifications)

If you unlock your bootloader then you lose the Bravia Engine, however Track id isn't in the same category as that and will be unaffected.
There are much better replacements to Track ID anyway in the Play Store.

all of that doesn't matter anymore though. SInce you can get your DRM keys back and your XZ's BL will be locked again once you flash back your own TA image.
So for now i am going only for root without unlocking BL

You can do what you want. Unlock the BL or not. If you backup your TA partition first you can do anything. As long as you backup your TA partition first before you unlock the BL. But if you really don't want to unlock the BL that is your call too.

Yes, maybe that's all he wants for now. Just letting the OP know that losing your DRM keys and BE2 not working anymore is yesterdays news. So the OP can do what he wants without the fear of losing the DRM keys and BE2 not working.
Thanks for your suggestion guys, since I am new to Sony so Just want to root for now and play around with stock ui, until i get bored
P.S. - Got my xperia Z last saturday , before that had Galaxy S2, and i have flashed it more than a 100 or 200 times till it went dead, dont remember.
There is a root method without unlocking your BL http://forum.xda-developers.com/showthread.php?t=2186368
I've tested this method with my locked BL, that works like a charm.

[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!

Root for Z1 Compact without losing TA

Is there a way to root the Z1 Compact without losing what you do when you unlock the bootloader?

The Compact roll out a week ago, at the moment there is no way to have Root or anything, the developers are working on it so stay tuned on XDA.

Not really true though, http://forum.xda-developers.com/showthread.php?t=2620794
But since there's no older firmware for the Compact you won't be able to backup the TA.
Since that thread was even posted before the launch of the compact, I thought it might be worth asking since alot can happen in a week....

I said there is no root ans still no root yet, that is just Recovery and will be a Root soon for Unlocked Bootlader but at the moment there is nothing for Locked Bootlader.
You have to wait.

Unlocking bootlader
Sorry for being a complete noon when it comes to rooting and bootloader and backups... and what not.
What exactly is at stake here? Just got my Z1 Compact today and learning from my previous devices, N7 and LG G2 (and mistakes) i kind of wanted to unlock the bootloader as soon as possible. Now i am reading all this about TA backup and loosing DRM , and feel both lost and concerned.
Should I bother with the unlock or rather wait until developers has gotten a bit further on this? Planning to use this device as a second phone for rough weather's and hopefully won't fill it up with to much DRM protected stuff (guessing that DRM is mainly for stuff bought through Sony?) so maybe I will be fine doing it later.
Any advice or suggestions are very welcome.
Cheers.

If you Unlock Bootlader you will lost your Warranty and DRM keys and like on Z1 you should lost X-Reality, Bionz Processing and Bravia engine. Losing this features will not compromise the working of your phone but DRM key definetly will compromise the warranty and if you lose them you will cannot Relock Bootloader anymore. Unlock Bootloader is needed if you want flash custom kernels like DooMlord kernel with recovery. So is recommended to Root first your phone and then Backup your TA and DRM keys so in the case you will want go back to Stock or go via Warranty you have just to Flash Stock FTF and then Relock Bootloader. But like I already said, there is no root for locked bootloader at the moment, and this is what OP was asking but he was just challenge me with Root for Unlocked Bootladers.

[Q] TA and DRM keys ? Am I ready to Root ?

Quick questions and no they haven't been answered directly the way I am asking them :
1) If I wish to later do warranty repair and I currently have a locked boot-loader is backing up the TA going to give me a 1:1 undetectable root and later unroot if I choose. (i mean all my gracenote, bravia, and other DRM's be returnable to stock condition)? (if so which method is the BEST.. ? seen a couple now)
2) My stock firmware doesn't seem to be on the FTF list is this possible I have a : c6906 C6906 14.3.A.0.757 Generic CA R10 ??? This one is on the list I don't think so ? Perhaps I am reading the string from the wrong spot.. ! In which case anyone know what to do to make a backup ?
3)Everyone hates this question but I have to ask does anyone here know of a way to unlock a locked bootloader :YES flagged device; I feel like a dink asking but after sifting through hundreds of posts there seems to be contradiction as in some people eventually figure it out and/or have unlocked z1's which I have read elsewhere that every single z1 comes from factory with bootloader locked yes?
Answer one of these questions for me make my day and you will have my many thanks to come

1) Why Unlock Bootloader for Root if you can get Root on Locked Bootloader? First get Root on Locked Bootloader then Backup TA and do whatever you want. Best way is with the application to Backup TA, with that one you can Unlock and Relock, as you already had read 100 post then you know which method you have use to backup TA, right? (no? then search again) BTW, Yes, after Relock bootloader with the Backup of your TA your phone will be stock like new.
2) Perhaps you should understand that it do not matter, download any Generic CA or International CA for your specific model C6906. Done.
3)What that even supposed to mean? Type *#*#7378423#*#* and go to Configuration, if there is Bootloader Unlock Allowed: Yes, then you can unlock it, if there is NO, then is no way to Unlock it. To unlock it there is only ONE WAY, google it.

1) I think you may be confusing root and unlocking the bootloader. TA partition backups are for re-locking the bootloader, not removing root. In fact you must be rooted in order to make or restore a TA backup. Generally only an unlocked bootloader voids warranty, not root. Though if you're worried about it, you can always flash a stock FTF and you will be back to stock without root.
For TA backup there's a Windows app that will do it, just Google it. Works great
2) Your firmware is there. Google "c6906 14.3.a.0.757" and it's the first link
3) As @eclyptos said, if your service menu says unlock is allowed, then you can. If it says unlock is not allowed then you can't and I'd say there's a 99% chance you will never be able to.

almost fully clear on this but still curious how my device is R10 which I don't see on the 6906 list.. I see r4 and so on.
I have read on a website that unlike z1s and other z devices every single z1 comes from factory locked. If so then how come some people have proclaimed the unlock success? Maybe that was just misinformation?
Thanks again will properly thank everyone later at home currently using the app

Yes, it's your misinformation. All of them have Bootloader Locked from day 1, Z1S is Locked Permanently and Unlockable, Z1 is Locked but can be Unlocked from the Official Sony Web Page, just google it.

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 )))
