Do not worry about it, it's just a software problem Slightly smiling Face

EDIT: seems there are quite a number of people facing the issue

Re: How can I root Xperia U on android 2.3.7?

Okh damon i'll provide you another firmware and if needed, we will get your mobile back to Gingerbread and wait until new build is released for Xperia U.

One question, is your phone locked to any network operator ? Like O2, orange etc ?

Also do try to connect your phone to another wifi router . Because the rom you flashed seems to be competey OK

This user flashed it and is not facing any problem 987

I don't know if this will work for you, but I've rooted my Xperia U using the steps from http://playfuldroid.com/tutorial-how-to-root-sony-xperia-u/ . Works like a charm for me though, so I think u can give it a try too.
