That's why i buy parallel version phones
no warranty, no worries :laugh:
I'd like to know too.
Yesterday, I unlocked my Z2, installed Doomkernel v0.9 and RomAur v3.1 and now miracast/screen mirroring gives me an HDCP error with my LG smart TV.
Anyone encountered this too?

Miracast/Screen mirroring doesn't work without DRM keys (you lost them while unlocking your bootloader).
We're working on a fix.
Ah well that clears it up. As far as I could find, losing the DRM keys only influenced the Sony unlimited services, not the rest. But that doesn't seem to be the case.
There is a trick to force HDCP working even without the DRM keys. It has been done on Samsung phones, I guess it's possible on the Z2 too.
Just wanted to say to any users still undecided about unlocking bootlaoder and rooting
just do it
x-reality just oversaturates colours and drains battery to process every image, i find i like images with it off.
the z2 has a fantastic display and colour range without x-reality
DRM keys never used any of the sony content in my life, infact i rooted and first things i removed was sony social and 'whats new app' which just run in the background drianing battery and probably monitoring your usage to send ads...
Mirorr linking is one of those cool, but probably never use/ use once in a blue moon type feautre.

Unlock that boot loader, root it and start modifying the phone to your taste ( the main point of getting android?)
You lose nothing vital

Thread is irrelvant now
Root exploit has been found so you dont need to unlock BL anymore
however you can now back up TA.img, unlock bootloader, install a custom rom and provided you use a stock kernel you can restore your TA
I am going to be new to owning a sony xperia z2 (first sony device i have ever owned) and I was reading and saw that the z3 was affected by unlocking the BL. (The camera quality in low light decreased)
so now after time has passed, I just want to ask if unlocking the BL on the z2 will at all effect the camera quality?
thanks for your time. sorry to ask this question again, the camera is very important for me.

Z3 YES
Z2 No
Sony are able to protect things from being stolen on Z2 so nothing at all is lost from bootloader unlocking
I havent lost anything at all exept x-reality but that has never ever worked at all for me

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.1
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

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

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

It seems not to have made any difference for me
I did take 2 pics one from before and after unlocking my bootloader

Iso 100
Spot metering
Exposure 0.0
White balance, cloudy
15.5mp/16:9

Analysis, 0 differences aside light assistance
Test result: nul
End results: UBL affects nothing
