Hi!
I've got a problem with unlocking my XPERIA U. It has Orange branded firmware, Android 2.3.7, and I'd like to change it to for example ICS. I wanted to unlock my bootloader, but I can see a message: Bootloader unlock allowed: No.
Is there any possibility to unlock it, or not? And why this phone has no possibility to do it?
Regards,
linoskoczek
Unlock = debrand? If yes, just flash stock ROM 1.54 or 1.75 with flashtool.
You can make branded ftf backup before flashing, just in case.
BTW why do u want to unlock bootloader?
Odp: [Q] Not possible to unlock phone - is there anyother method to do it?
No, you can't unlock your phone. Probably you have simlock and locked bl by operator(Orange). But you can flash fw without Orange apps etc. Just go to development section and download latest ICS fw.

Ahh that ****ty orange...
I've flashed it to ICS, but still unlocking is not possible. Anyway, do you think http://forum.xda-developers.com/showthread.php?t=1886460 will root the phone? It's just a one thing I can do without unlocking xperia.

I think the only thing you can't do in SXP with locked bootloader is flashing custom kernel. So, the answer is yes, you can root the phone without unlocking bootloader as well as e.g. install CWM recovery.

It allows you to put custom roms and custom kernels. It also voids your warranty.
If you phone is sim/network locked (in service menu it'll say something like: "Bootloader unlock allowed: No"), then you cant unlock bootloader unless you pay someone to unlock it with network unlock codes. Afterwards you can unlock it via offical (SE) or test-point method.
yes. subforums you try to check on development. there are many tutorials to unlock and root

Yes it is worth unlocking the bootloader. With an unlocked bootloader you can do almost anything with your phone.

Well that depends, it might have been worth for you, but for someone who likes stock rom and has no need or will to change it with custom rom (except few tweeks that can be done with root), it's probably best to keep it locked. I look at it as a pretty subjective thing. If losing warranty is not an issue and you want to go that extra mile, sure, unlock it.
can somebody tell do i lose warranty on the phone if i unlock bootloader through the official way (sony webpage)? I mean can the guys where i bought the phone find out that i have unlocked bootlader even after i have locked it again?
Yes you always.. official unofficial ... Read below...
http://unlockbootloader.sonymobile.com/instructions
ok...but if i unlock through official way and i need to take it to the service and i relock it again can they find out that i had unlocked bootloader before?

Sure, because your IMEI was used for unlocking bootloader.

Is it possible to Lock Bootloader Xperia Go again? Why do we need to unlock Bootloader for Xperia Go if the only one working rom there (zip or FTF) is exactly the same as the Sony stock rom...?

you may want to read this post first: http://forum.xda-developers.com/showthread.php?t=1527159
yes it is possible to relock bootloader for any android but that depends whether it is developed by devs and available yet for that phone. try find out at the development section for your phone model.
unlocking bootloader is required if you want to root, for superuser function, customize app functions and etc, which cannot be done in locked bootloader. you also don't have to unlock bootloader if you only want to upgrade your phone or change your stock rom to other region stock roms, just flash the file using flashtool. hope this helps

If you want to install a kernel like lupus, first you need to unlock your bootloader. Use this tool to unlock it.

The risk of brick your device, but a lot of people already unlocked their bootloaders without any problems, your DRM will be permanently deleted, but believe me you can get more from your phone when the bootloader is unlocked, really worth it.

And you loose your warranty
Drm won't be lost if you unlock using testpoint method.

First check the bootloader status.whether its unlocked or not.
If its already unlocked then you can flash any custom kernel.If not you have to unlock BL first.Its not harmful but it will avoid your phone warranty.Try to use SE web site to unlock BL.Its the safest way..
After unlocking BT u can flash kernels anytime using Flash tool™..
Re:How to install a kernel
To install a custom kernel,you have to unlock your bootloader and there are two ways of doing it:
1.Use the official sony method...
head to unlockbootloader.sonymobile.com and follow the procedure there..
by doing so you lose your DRM keys which means services like track id wont work anymore...
2.use a testpoint method which is a bit complicated but you retain your DRM keys
for the testpoint method check this out
http://forum.xda-developers.com/showthread.php?t=1730874
Bootloader unlocking should be done carefully,you might brick your phone if you are not careful..
after the unlock is complete you can use flashtool to flash a custom kernel in fastboot mode..
Do I need to unlock the bootloader if I want to downgrade to GB from ICS?
and is there any other way to unlock the bootloader without the official SONY method?

No. The only reason you have to unlock your bootloader is in case you want to install a custom kernel, otherwise there is no reason. O don't know if there is any other way to unblock bootloader except the one from Sony and honestly I think there is no reason.
To downgrade from ics to gbe you have to install flashtool on your pc and download the gb ftf file and flash it.
There is a tutorial on YouTube on how to use flashtool on arc and the way is pretty similar to st27. The only thing you have to do is find on st27 development thread the drivers and the gb Rom. Here is the YouTube tutorial
