[Q] Unlocking Bootloader - What is important? - Sony Xperia T, TL, TX, V

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?

root your phone then use Backup-TA-9.10 to backup TA first then go to http://unlockbootloader.sonymobile.com/instructions and follow guide here. so you can unlock very easy

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?

i think all app you can install again, backup only image, video, phone book.
the order is correct. i dont like to use AOSP rom cause the graphic interface not as good as sony.

Factory reset wipes everything, except SD. I don't know why you would say that 'nothing will be wiped'

Just check the 'Original Development' section. Whatever ROMs people like is down to personal preference/requirements, so we mostly suggest to just try them out yourself

There is no original development section for XV, but I checked several of the kitkat roms' threads.
The people there are complaining about bad standby time.. And that the roms are not suitable for daily use.
Would you agree that kitkat is not yet ready?
I don't care about minor bugs, but that bad battery life or a not working camera (just an example) would not really encourage me to install 4.4

[Q] How to root an Xperia TX???

So yea, I'm looking everywhere on how to root an Xperia TX. I admit I'm a bit of a noob but I just want to root my phone. I previously had an Optimus One and I successfully rooted that and applied a custom recovery loader along with a custom ROM aswell so I'm not a complete noob.
Every where I look, the website is either not reliable or the guide is for the Xperia T or V. I'm a little worried about following an Xperia T guide so I just wanted to ask what would be best to do or if anyone has a guide that they can link me to?
Thanks in advance.
I have to say, I am really enjoying the community even though this is my first time posting.

First.
Remove the mention of the app from the OP. Any mention of warez etc is banned from xda.
Secondly.
Just follow the instructions to root.
If you are on newer firmware 195 or 223 then flash a TX firmware that is 303 (Or equivalent)
Then use bin4rys method to root, then the method to update back to newer firmware whilst keeping root. Its all in that thread.
Same for me, it wasn't clear in that thread.

You just saved me and my phones life I just ordered a TL29i and it will arrive next week. First order of business is to root! Do these come with a locked bootloader? I know Sony has a website to unlock it for "developers."
It depends, I would have asked the people I was getting it from before you ordered it... Beyer hope it is otherwise there is no unofficial way to unlock yet

Ah, your OP was a bit vague. The others, including me, were thinking that you were talking about the external storage. Have you unlocked your bootloader? Have you succesfully flashed a rom through Flashtool, without modifying any of the options?
My bootloader is locked... I do not was flashing with custom roms... From night,to the morning stop working by himself... I'm flashing stock rom again...with flash tool and Sony Pc Companion and still not work... Its very weird...

This is my understanding too. Bear in mind that as soon as official updates are released a developer here will make it available on xda. This means you often get updates before you would normally (because they are rolled out at different times depending on carrier and region).

Usually a carrier locked xperia has a permanent locked bootloader. Don't be surprised if you can't unlock it.

It is an issue if you want those highly customisable roms such as cm,pac etc. I rather lose be2 than not having the chance to flash those. But now there's a way to save your ta before unlocking bootloader so it's all good for those who want to unlock bootloader and still keep be2 for future use.

Yeah viper rom was always great in htc phones. I know not it since htc sensation. CM always seemed broken. Always something isn't working what works on other roms. I always wondered why CM always seems to have issues with things.
