Hi.
I upgraded my Sony Xperia U to ICS few days ago with official Sony update using PC companion. The phone became laggy and slow and sometimes it Hang then i have to remove battery otherwise it doesn't work, Capturing with camera becomes too slow, takes lot of time to start.

Can you guys help? Please tell me how to downgrade to GB and i need official GB not modded. I am from India.
Please tell me how to do this or give correct link for a tutorial?

Hi experts,
Purely i'm new to this blog and also the android platform. I don't even know about unlocking bootloader and all that stuff (just heard my friends saying). I have an xperia mini pro sk17i and was having GB 2.3.4 at the time of purchasing.Now when official update for ICS 4.0.4 had came,i updated without knowing that it will affect my xperia's performance.Now i started getting lags in games which was very smothly running in previous OS (GB). I would like to switch back to GB and want to root ( also from my friends conversation) the GB.
I need a complete guide for this because i should not end in a brick state,whether to do an unlock bootloader, or flash it, which tools to use and all.... Kindly help me guys.......

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

The latest official update from Samsung/AT&T is Ice Cream Sandwich, not Jelly Bean. It's also not available OTA (Over The Air) because of its size; you need to download Kies (basically Samsung's version of iTunes minus the store) and it can install the update when you plug in your phone via USB. If you want Jelly Bean now, it's going to be rooted, and it's going to be quite buggy. Expect many random freezes and reboots.
By the way, here is the correct forum for you: http://forum.xda-developers.com/forumdisplay.php?f=1493

[Q] Xperia U downgrade

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
