[Q] Xperia U downgrade - General Questions and Answers

Bare with me if I'm posting in the wrong place. This is my first post and I am feeling my way. I have a Sony Xperia U which I upgraded to ICS 4.0.4 from
GB 2.3.7. The phone has been a nightmare ever since and can at times be almost unusable, ie, 2 minutes or more to pull up a number from contacts - not ideal in an emergency! The camera misbehaves and trying to use the web is so slow that it's painful. My wife has a Xperia Neo with non of these problems.
All I want to do now is downgrade to the previous software (GB 2.3.7) but my bootloader says unlock allowed : No. My question is can I do this with a locked bootloader and how? Or can it be done at all. Some people are say that I need to return my phone to Sony and some say that is not necessary
I seem to get conflicting information. Any help would be appreciated

[Q] Custom ROM Compatibility

Is my Motorola Xoom Supported?​
Hello, i am getting a motorola xoom 32GB wifi only UK model for christmas. Being me, im not planning to stay on stock for very long, in fact more like 10 mins
However, i have one bugging question before im confident enough to apply a rom and unlock the Bootloader.
Will my Xoom (being a UK model) support Tiamats roms? Ive heard conflicting reports saying yeah because its the same hardware and no because of the model, but i just need 1 definite anwser from a user whos tryed.
If its no, then will i have to get a US firmware for it? Is it even possible?
I have experience in android hacking and have done so with my Sony ericsson Xperia x10.
Thank you in advance for spending the time to write a post.

Sony Ericsson Xperia X10
ROM: FXP CM7.2

Maybe this is Stock but it is 2.3.4 and is stable but you have to unlock bootloader
You need not unlock the bootloader to downgrade. Just use flashtool and get your GB ROM. Have a look at here http://mytechencounters.wordpress.com/2012/03/17/root-your-xperia-phone-without-voiding-warranty

[Q] I want to update Sony Xperia 4.4.2 unlocked former bell phone now wind to 4.4.4

Hi guys,
I just bought a user Xperia ZL phone. Works fine, but I noticed the battery drain and overheating. So I also know 4.4.4. is the latest from randomly googling. I saw the that the 4.4.2 has an issue.
I was also curious with the oneplus one phone to get cyanegonmod on this phone.
However, I'm a bit confused what to go for and how to go about doing it. How do I know for sure how my phone was unlocked. GUy I bought it from he said someone did it for him and he paid them 40 bux... but how was it unlocked? Was it a softare unlock? How could I know that? If it is, how would I go about safely not screwing up the unlock.
Finally I would like to go to 4.4.4 preferably CM ROM
No one able to assist me in the right direction?
