On you second pic, there is unknown error. Means your drm keys are not applied.

Camera quality will be noticed clearly in low light shots, you will see red-green dots due to BIONZ X doesn't work anymore to denoise.

Your DRM keys are lost if you havent made a backup, they are not active curently according to your screenshot.

I have just attempted to recover my previously stored TA partition with Backup-TA tools, and now after reboot my phone seems bricked. It only vibrates slightly and blinks red light when I try to switch in on, but is not doing anything else.
Is it dead, can I hope to be able to recover it?
Anyways, be very careful guys, when it is coming to TA partition.

Red light blinks? The bootloader is still unlocked... Thats what i read in this forum.. Anyways guys i deliberately let the drms go.. I was trying to back them up.. But it was not getting.. Got pissed and unlocked the bootloader.. Anyways i will stay on rooted firmware with the drm restore mod.. To be honest i hate Sonys front cam in z2... Pathetic!! My Note 3 Neo was way better... But i just love Sonys rear cam.. Excellent i will say.. Only wish if the front had been same..

Yes, red light blinked and the phone would vibrate when I tried to power it on.
Strangely enough, the phone appeared LOCKED when I tried to recover it with Sony Flashtool, so the tool could not proceed, as it is only for unlocked phones. Though I am pretty sure it was unlocked.
Nevertheless I was able to recover the phone with regular Sony PC Companion, so no harm done, but again, I would recommend to be extremely careful when fiddling with TA partition, DRM Keys etc.

Ok, but now after all the trouble I had to go through, I have all my Keys restored.
Not that it was the purpose, though, but It's better to have working phone than a bricked one.

Update:

I don't know how but you guys have to see this.. My drms are absolutely intact.. I was on Resurrection Remix.. And the camera quality was poor as compared to Sony.. Initially i thought since i have lost the drm keys i better flash the latest prerooted firmware and use the drm mod to restore to some extent..

But after flashing i was just curious to see the difference without drms and so didn't flash the mod.. And to my surprise!! Everything works great!!! The camera is same as it was before i used.. X reality and other stuffs are working great!! See the samples below...



Macro shot in low light..


Some other camera samples..

8 MP MANUAL


20 MP MANUAL


8 MP SUPERIOR AUTO


Front cam..








I don't find any degradation in performance.. Its the same awesome Xperia Z2 that it was...
Sorry to spam guys.. But believe me no degradation!!

Now please don't say me that the effects of losing drms can be seen after i lock my bootloader and bla bla... Because if that is the case then i will stay like this only!!

Cheers guys!!

X-Reality, DSEE HX, Noice Cancellation, they can be turned on/off that doesn't mean they can work. And I see red and green dot (noise) in this pic, it means BIONZ X doesn't work. If you wanna know does X-Reality work, just go to a showroom and open one picture on your phone and another one in showroom (with DRM), you will see the difference (easier to see with blue and green color). Then other functions will not work as well.
