Hello everybody!
I have decided that I'm going to unlock my Xperia V's bootloader. Perhaps I will do so this weekend.
But I need some information on all this stuff.

First of all, what are the important things to do before unlocking? Like for example backup TA partition and so on. How do I do these things?

Also, can anyone provide me a failure-proof guide on installing an AOSP rom? I think I want to install this Carbon room that appeared today in the XV forums.
I am currently on unrooted stock 4.3 (had some issues with my recovery some time ago, so I had to reset..)

I would also appreciate a summary of what is NOT working currently in the 4.4 roms, and if Kitkat is already stable enough for daily use on our devices.. (And perhaps also what impact an AOSP rom has on performance in benchmarke etc.)

Also, which kernels do you recommend?

I know, it's a lot of questions, but I just want to make sure I don't brick my phone.. It's the first time for me messing around with bootloader unlocks. ^^

Any replies/ helpful links/ advice are greatly appreciated.
Thanks in advance!

Ah, I forgot one question...
Does project butter work in 4.4 as well? Is it as smooth as stock 4.3?

Don't forget that unlocking your phone also factory resets it so backup important stuff first.

Alright.. And to root I'll have to go back to 4.1..

So, is this order correct?

-Optional Backup (don't know how to backup my apps without root tho. :/)
- Flash 4.1 ftf
- Root with Doomlord
- Backup TA
- Unlock BL
- Flash CM kernel (by the way.. How? i have never used this fastboot thing.)
- Enter recovery
- Flash rom zip



Still need some information about these kitkat roms, guys.. Any experiences? Any replies to my questions in op?
