Hi guys I'm just wondering what feature/s am I going to loose when I unlock the Bootloader of my Z2?
You are going to loose BionZ, X-Reality and Noise Cancelling functionality
and youre gonna lose warranty because you will lose TA partition which includes DRM keys so before you do this just backup your TA partition search in google you will figure out how, and whenever you feel you wanna get back to stock and relock bootloader just restore the TA partition and you will get back to normal

I am about to get my phone back from repair, it's sitting at 4.4.2. I don't want to unlock the BL but would eventually want root and probably to force an update to 4.4.4 if my provider doesn't have it.
Do I need to backup TA just to root? To install the dual recovery? To flash FTF? I understand that it's usually good practice anyways, but which operations actually muck with the partition?
only Bootloader unlocking will wipe your TA
nothing else
Hello guys
I am probably getting my self an xperia z2 this week...
So my question is:
Since i go mad when i get a new phone(desperate need to flash everything out there such as roms, kernels etc) , I need to know what do i lose if i unlock my bootloader and if i do lose something can i get it back?
Please answer only if you are certain of what you are talking about, i want to be free of doubt if possible
There is a lot of debate on what is lost/broken when you unlock the bootloader. As far as I'm aware X-reality, Super Vivid, noise cancelling, and a few other things get lost. It is able to back them up (By Backing the Ta partition up) and restore them at a later date, restoring them re-locks the bootloader though. To back the TA partition up you have to be rooted, you can find guides for that in the general section (there is no one click root method for 23.x.x.x.x.x firmwares btw). @Envious_Data you got any more info on the subject?
from my testing
you lose:
warrenty (region spesific/carrier/international)
X-Reality
Bionz Image processing
the last one effects camera quality but isnt a complete death of camera quality its somewhat worse but its not something to complain about because the device is still able to perform well
x-reality only works in the album app so no need to worry unless you like your pictures being slightly oversaturated and super sharp
i recomend downgrading to 314 via FTF>flashtool and rooting the device so you can backup your TA using the TA backup tool
after you have backed up your TA, store it somewhere safe, google drive, usb stick anywhere you wont lose it
unlock your bootloader and have fun, so long as you dont brick your device
Guys, I'm new to Sony Xperia Z2. Yesterday I backed up my TA partition with TWRP, today I unlocked the bootloader. May I safely restore the TA partition when the bootloader is unlocked, and even after I update the firmware?
I have read a few warnings that wrong TA may permanently hard-brick the device. So, that's why I am afraid.
if you restore someone elses TA it'll brick your device
you have to be on a stock kernel to restore your TA as doing this will relock your bootloader
Then that's fine. The kernel and entire firmware has not changed yet. TA backup is mine.

Hello,
I've searched forums but since I dont trust my english, I couldn't find a thing. So, apologies if this was asked already.
Is my warranty void upon requesting bootloader unlock key, or is it when I actually unlock it with that key? Because sony seems to save imei codes in their site. I live in Turkey btw.
Also, another un-related question, is my phone diving-proof ?? I mean, I've shot a couple of videos and photos in pool, but I'm scared to just jump on it with my phone ?
Unlocking your bootloader wipes your TA partition where your unique DRM keys are kept
Xperia Z2 is IP58 Certified to water resistancy meaning it can survive underwater at 1 meter for 30mins or less distance for more.
Thanks for the reply.
I know, but since I am rooted on locked bl, and backed up ta partition, it should be ok to unlock, right? I mean if I restore my ta backup, I get my warranty back or..?

Yep, restoring your TA relocks your bootloader so flash a stock kernel before you restore.
Hey all
New to the Z5C and just wondering what the go is with the TA keys?
I know with the Z3C (Previous phone) you had to backup the TA keys or you lost them forever, is this the same with the Z5?
If I were to unlock the bootloader would I loose the DRM keys forever like the previous models, or can they be recovered by re flashing a firmware file?
Thanks

You will lose your drm keys. There is tool which you can take backup from your drm keys. now there is also possibility to restore drm keys (emulate them) like on previous models.
This
http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
Also kernels like androplus kernel and xpower rom contains drm restore by default
If phone needs repairing under warranty i think you need ta-backup
Not that I ever bothered with backing them up but yes it's the same with the Z5C too. Once you unlock the bootloader it'll wipe the TA partition too along withDRM keys so better back it up if you want to hold on to your warranty and whatever Sony proprietary features on the stock ROM. And if you happen to lose the DRM keys do not try to flash someone else's on to yours otherwise it'll be an epic brick.
Also if you do happen to lose your DRM keys you can still enable the sony features with custom Roms/kernel available.

Can anyone tell us if reflashing the stock rom over a custom rom will reinstate the LOCKED BOOTLOADER and the DRM KEYS!
Your help is always appreciated, Thanks in advance.
Will not reinstall them. After unlocking of bootloader DRM keys are gone forever. The only way to keep DRM keys is before unlocking of bootloader to make backup of TA partition.

Every thread i have been on, require us to root the device first!
So does that mean we cant backup TA Partition for DRM KEYS? As for root bootloader should be unlocked for this device.
With Lollipop phone can be rooted without unlocking of boot loader. Then you can make backup of TA partition. After backup phone can be upgraded to Marshmallow, then bootloader can be unlocked and phone rooted. In fact my phone also is rooted, I don't need DRM keys and don't make backup of TA partition. Why you need backup of DRM keys?

Thanks for such a fast response.
The reason is because i really want to root my device. But people over net sometimes complain for issues at camera(quality reduction and non functionality) after unlocking bootloader. I dont even know if these are really related. I just wanted to be ready if anything happens.
Please tell having a TA BACKUP for DRM, is that necessary or not. And TA BACKUP from my lollipop will work at my marshmallow as well ryt!
My phone is rooted and don't find any quality problem with camera or something else .
