What does it mean ? Is Sony Tablet has non-unlockable bootloader or my bad english plays a bad game on me?
My Question
When will you release the bootloader key for Sony Tablet S ?
Reply from [email protected]
Hi,
Since the Sony Tablet S was created in another team than Sony Mobile the opportunity to add an unlockable bootloader on this tablet was not possible.
Sorry to bring you the bad news.

Xperia tablet s is built by sony, not sony mobile. Just under the xperia branch. The xperia tablet z is the first tablet to be built by sony mobile

Hi,
So after reading a bunch of posts, I want to verify if I understand the current state of things with the Z2
- There is no current way to backup the TA partition on the Z2 right now.
- Because there is no way to backup the TA partition, if i unlock the bootloader I will lose all the DRM keys
- There is no other way to root the phone then unlocking the bootloader
If I understand that correctly, a few questions:
- besides X-Reality, trackid, what are some of the important/desireable features that will not work without DRM keys?
- I'm coming from an S2. How might i transfer apps and data onto the Z2? I was planning to use Titanium Backup but without root this doesn't seem possible
thanks in advance.
Everything works, x reality, track id blah blah :-/

Are you saying that even if i root and lose the DRM keys, X-reality and trackID will still work?
If so, what are the DRM keys used for? i.e. what will break because DRM keys are gone?
Yes they will work, DRM = Digital Rights Management which is for protected digital content only

Ok, after more digging, it appears that the xperia Z line uses DRM to also lock things like "Bravia engine" (x-reality) and other things like screen mirroring.
http://forum.xda-developers.com/showpost.php?p=53134830&postcount=328
even tho you can toggle it in settings, it is permanently disabled.
on a side note, regarding migrating over from S2 to Z2 when it doesn't support root, I found helium.

X-Reality can still work after unlocking your bootloader and rooting, plenty of threads.
X-Reality is not the same as Bravia engine
Screen mirroring, 4k video, blah blah blah, everything works except for the DRM related apps such as Music unlimited and Video unlimited.
Camera function and quality is also NOT affected.

Nothing at all stops working when you unlock your bootloader
There currently isnt any way to backup TA or drm keys
If you unlock ,your TA is wiped along with your data and internal storage
TA partition is where drm keys are stored
You can use google services to backup your apps and this can be found in your settings for some devices, there is app2zip which i use to use but i think app data doesent work right on KK
When i can ill be posting a ref/info thread on all you need to know in the QnA ill ask for a mod to pin it

Camera quality might decrease someway (MAY decrease, i'm not sure)
this surely occur on z1, but looks like no one test it seriously on z2

No, nothing at all changes when you unlock your bootloader, besides your TA and the fact that your warrenty is voided

Oh let me add some details i missed
All xperia devices that have KK 4.4 are not affected by Unlocking your bootloader, its been proven quite alot here on XDA,
Unless sony treat a spesific device differently which may be the Z1 which i doubt because KK FW for xperias are very alike, just minor config differences and device spesifics aside the kernel

Thanks for the info
actually Z1 has all other features including X-reality work on 4.4 except the extra camera quality, which the effect is proved to be significant in low light
if all sony kitkats are similar, then i have a bad news for z2....
hope it isnt anyway, and hope some1 can port the LB exclusive effect to z1

Well remember this although KK being simular its based on Z2 firmware, sony are lazy, they dont rebuild, they port
So sony probably lowered quality of KK for Z1 in an attempt to lure people to other xperias but it seems to be failing

O maybe u got me a bit wrong
i mean the quality of camera on Z1 with LB is significantly better than a Z1 with UB, there's a thread about it
http://forum.xda-developers.com/showthread.php?t=2722106
(well, X-reality still works on UB Z1)
Unlike Z1, Z2 has no return for unlocking the bootloader. U cant swap between locked and unlocked to test the difference
so i doubt there might be somehow of difference between LB and UB in Z2 even if u still think photo looks great on UB Z2
Has any other sony kitkat devices made such test between LB and UB photo???

Probably not, i know UB and LB is exact same with Z2, because i posted screenshots and stuff proving everything works
It seems only Z1 is affected by UB all others are totaly fine, im unsure of Z1 compact though, seems to be lacking solid information

Come on I'm talking about camera quality not X-reality
X-reality works on all sony 4.4, we agree that
I mean the photo u took after unlocking the bootloader may have worse quality compared to that in locked bootloader

Iso 100
Spot metering
Exposure 0.0
White balance, cloudy
15.5mp/16:9
Edit:1st one is before
2nd one is after
Analysis, 0 differences aside light assistance
Test result: nul
End results: UBL affects nothing
