Hi all, I'm so sorry for posting this if there is similar thread. I've searched a lot about my problem, but still can't find a resolve. I want to update my Xperia T (LT30P) to JB 4.2.2, but my phone says "bootloader UNLOCK allowed:NO". I have read some threads but they are all too old and maybe outdated. I'll be very thankful if you help me to update my phone. Thanks!
Only if a rom uses a custom kernel you will need an unlocked bootloader. Stock based roms can be installed on a locked bootloader. There is however no 4.2.2 stock based rom, as there is no stock update to 4.2.2 (yet).
It really has all been covered in the All in One thread (sticky in this forum).

so I can't install even the CM10 ?
No I can't either for cyanogenmod you need a custom kernel which needs an unlocked bootloader

Did you read the first few lines in the first post in the first thread in the Q&A section?
It clearly states that if it says no, then you cannot unlock.
No unlocked bootloader = no custom kernel = no Cyanogenmod
same
I also encountered cases similar to yours and send mail to sony but they say that this case can not be unlocked

Right. What happened in that thread was Sony Xperia support gave customers of Movistar (one carrier) an opportunity to make arrangements to send their phones to Sony, so they could physically unlock their bootloaders for them. Sony offered that service to that specific group of Movistar customers that had received SIM unlock codes from Movistar. It's a little bit of an exceptional situation.

I dont think that its an exceptional situation. I'm from spain (sorry for the misspellings), and Sony Its unlocking bootloaders from all providers, in my case one Xperia V from Yoigo (Telia spain) its now on the Sony service for changing the status from unlocking allowed: no to yes for free.
This situation its a mess from sony, because all the devices sold as unlocked where unlocked from provider and can be unlocked the bootloader. But the ones sold from providers and locked to them, once you obtain de unlock code (from Yoigo in my case) only unlocks from provider and not the posibility of unlocking the bootloader.
The conditions for changing the status of unlocking the bootloader are that you have previously unlocked the provider by any way, I mean buying a unlock code or obtaining it from your provider. And prove it with the unlock code + IMEI contacting with sony by email. Then in one or two weeks sony will contact you to take the phone to unlock. Try contacting Sony, you have nothing to lose.
If you can read spanish or translate it here you have to posts where I take the info:

Hi!
I got my V unlocked from Sony. I'm from Yoigo too and after conctacting Sony, they took my phone for free, changed the status to Yes and returned to me.
I read about it in the spanish forums htcmania (in the links provided in the previous post), tried it and worked

Thank you #gregbradley
Actually, I wanted to Flash Custom ROM on my Device but many article says: "Unlocking the boot loader allows you to put custom ROMs on your device" It is true ?
Regards,
Clasher_RS
It depends if the custom rom needs a custom kernel, some do, some don't
But in general, if you find the custom rom in the development section you only need root and not an unlocked bootloader, but if it is in the original development section then you need an unlocked bootloader as that rom requires a custom kernel.

Does anyone know if TMobile brand Sony Xperia Z able to flash the other ROMs. I know it's BL and will lose TMO Wifi call function. But TMO stop at 4.3, and I cant see any hope for 4.4, 5.0. Is possible to flash other ROMs? Thank you.
Yes, you can.

WIFI calling function will not work ofcourse but if you are not satisfied you can flash stock firmware anyday using XPERIA FLASH TOOL. You need to unlock the bootloader using official Sony Method. If you can unlock the BL which I was able to.
Then you can download and install Cyanogenmod 13,12,11,10. (C6603) - Yes, it has issues, so I switched to.
SlimKat 4.4.4 - YUGA (C6606) - NO BUGS AT ALL.
Also do remember to flash SGAPPS from their repository no the opengapp.org gapps.
Big difference I found is that Stock OS on new flash takes around 500-700MBs of RAM where SlimKAT takes only 350MB w/o GAPPS and 500MBs GAPPS.
Good luck! I will show you screenshots

The official tutorial is over here: https://www.youtube.com/watch?v=jWPYicb8_-Q
I guess that means there's still no way if your C6606 says "Bootloader unlock allowed: NO".
I own the Xperia SP since 2013. I recently got a Galaxy S6. The issue with the Xperia SP I had was like many others, even after Carrier Unlock, the bootloader unlocked allowed remained No. Hence I was very limited to the ROMs I can use. We don't even have Lollipop stable enough for daily use. UBL right now has Marshmallow and also Cyanogenmod Nightlies which I would like to try out on my Xperia before I root my Galaxy S6.
So do we have any updates for SP users to be able to unlocked the bootloader? I mean neither Sony nor carriers support the device anymore, they should allow us to play with it now, no?
Please post any updates here
i agree they should tell us how to unlock it as no -one supports it anymore
I read somewhere (i realy dont recall where) that sending your phone to sony so they can unlock the device for you. is possible.....
Any news ?

Greetings friend,
I've personally emailed Sony asking for official way to unlock bootloader of my LT29i.
Unfortunately the reply was unfavourable , this means we'll have to unlock bootloader using unofficial method.

Hi buddy, I've verified that by selecting Xperia T in the Sony Official Unlock Bootloader link is working on Xperia TX as well as long as the IMEI you provide matches your device (selecting Xperia V may also works). Now my bootloader is unlocked. :fingers-crossed:
