How to Install Xperia U ST25i official Ice Cream Firmware

This tutorial works for the Sony Xperia U ST25i and it works with rooted or unrooted phones without unlocking the boot loader.
Please consider that flashing a new firmware may void your warranty or damage your phone which is only your own responsibility.

For the Android 4.04 Ice Cream firmware I am using the official one, it is not a custom Rom but the official one that will be available through PC-Companion (but it is not the case yet), so if you cannot wait and you would like to try, read on.

Steps to install official ICS (Ice Cream Sandwich):
  • Back up your phone memory with PC-Companion
  • Uninstall PC-Companion (I had to do this so the tool would pick up the good drivers)
  • Enable USB debugging on your phone.
  • Donwload Flashtool and firmware (here is the full tutorial and download files:
  • Install Flashtool and uncompress the firmware files.
  • Copy the firmware file XperiaU_ICS4.0.4_nu.ftf into the c:/Flashtool/firmwares folder
  • Turn off the phone and open Flashtool, click on the thunder button and on firmware selection choose the file XperiaU_ICS4.0.4_nu.ftf
  • Don't change anything and click the OK button.
  • Now press volume down and connect the phone at the same time to your pc with the USB cable.
  • The process starts automatically: keep the volume down key pressed all the time untill you see "Finished" in the log tool.
  • When it is finished disconnect the phone from your PC and turn it on.
  • The first boot may take some time.
Here are some pictures:
Chose the official firmware file:

Flash process starts automatically wait untill you see a good message like this:

It is a good idea to back up the memory because the flashing procedure wipes and deletes everything. When everything is done reinstall PC-Companion and recover your data you will be happy to find all your old messages, programs and configurations and connections and you start enjoying Ice Cream Sandwich on your Xperia U ST25i right away.
This firmware is debranded, no custom logo, nothing! Just the way I like it.

That's it, enjoy!

Xperia U How to Disable Illumination Bar

I've got my new Sony Ericcson Xperia U yesterday and it is really a fantastic phone. The illumination bar on the bottom can be annoying at times, specially if you don't want to get all that attention all the time.
I've tested a few applications in order to disable the bar led illumination, and here is the only one that has worked for me (Screen Filter):
Just make sure that you uncheck "Enable soft-key bakclight" and that will disable the led  bottom bar.

Nevertheles this will not desactivate all led notifications, you will still get notifications while browsing pictures or watching videos, but all the other notifications will dissapear.
