The aftermaths of BL unlocking - Xperia Z2 Q&A, Help & Troubleshooting

Hi guys
I have a D6502 which I bought a few months ago, I'm now on 5.02 Rooted, modded and it's just great
I'm a power user (not as naughty as I once was) and to be honest I'm satisfied with Sony's stock unlike other OEMs', however, I have tested CM 12.1 on an S III and I liked it's animations and the UI, it's very sweet :victory:
I now would like to test CM 12.1 on my D6502 and in order to do so, I'll need to unlock the BL, I have already checked the status and it's unlockable, and I have already dumped the TA partition. The question I have now is that, will I lose some functionality if I unlocked the bootloader regardless of dumping the TA partition, or it's enough to reflash the TA partition and my phone will be just like it was before unlocking the BL?

I used to think like you too. I'm using my Sony Xperia™ Z2 (D6503) with unlocked bootloader for a long time now and I didn't notice any missing feature. Pretty much everything works, except one thing: I don't receive OTA updates. So, "Update Center" app is just junk for me.
Yes, reflashing the TA partition would restore your DRM keys, but under one condition: You MUST have a STOCK kernel installed. Only then you can reflash your TA partition back. If you have a custom kernel installed and you try to reflash your TA partition which you've backed up a while ago, you'd end up having big troubles, fyi.

I unlocked the BL on my Z2, I used CM12.1 for a few days, it was great, but I felt the battery was better on Stock ROM, I flashed my TA backup and everything was fine.
However, I have now unlocked it again

Just an extension on your post. You need stock kernel, stock FOTAKernel, and stock based ROM. Bootloops are a sure thing else.

Unlocked bootloader, Update Center/Whats New works perfect.
