[alvlir]

hi

I want to update my xperia u but sony pc companion show this message:

your phone is up to date!

here is my phone information

model number: ST25i

android version: 2.3.7

build number: 6.0.B.1.564

SI 1261-4288

note that I try update through sonymobile.com but again I see that message:

your phone has the last version!!!

you have to contact a Sony moderator to find out which country your SI belongs to, you should just flash with flashtool

Use SUS for update first try to update with normal mood if its work then good if not start your windows on safe mood with networking and run SUS again then update will work surly its happened with me as well.. Good Luck!
