I'm not sure how to do this. First you say I should
"WILL NEED TO UNLOCK BOOTLOADER! Check this thread"
In that threat you say
"if you want to backup the TA or keep ur DRM keys,first root the device and then check this out"
but to root you say
"once you have flashed the kernel from the 1st post"
How can I root without flashing, how can i backup stuff without rooting?
I don't want to lose/corrupt my phone.. I'm new to this, please help me out
Sounds like you may have not applied the patch correctly as others have reported the Bravia Engine to be working and have provided proof.I tried it and it doesn't work, the bravia engine seems not to be working too...

STOCK ROM FW:
4.4.4 - 23.0.A.2.105 - v01
or ROMS BASED ON THAT FIRMWARE
Certain pre-loaded content on your device may also be inaccessible due to the removal of DRM security keys. For high-end devices running recent software versions, for instance Xperia Z3, the removal of DRM security keys may affect advanced camera functionality. For example, noise reduction algorithms might be removed, and performance when taking photos in low-light conditions might be affected. The secure user data partition may also become inaccessible, and you will not be able to get any more official software upgrades if you unlock the boot loader.

Kinda sad for those who believed Doomlord original statement in his OP that said the camera wont be affected, especially when there was a lot of speculation.
TIP: Dont make such statements without solid proof, it'll mislead users. Theres probably at least one poor soul who unlocked and now has a poorer camera.
Wajk! Buddy! Glad to see you here!
Did you get a Z3C? ;D
I'm sorry for maybe asking this noob question, but ain't there a way to relock the phone and install a ruu like it's on HTC devices possible? Or ist really a fact that you can't gain access to the DRM stuff anymore after unlocking? No way to undo the unlocking?
