Cool rooting and flashing

TO REPAIR UR PHONE :
1. FIRST OF ALL DOWNLOAD FLASHTOOL AND INSTALL IT, THEN GOTO C:>FLASHTOOL>DRIVERS and then run "flashtool drivers.exe" , and check all options.
2. DOWNLOAD XPERIA U ANDROID 2.3 OR 4.0.4 FIRMWARE FROM INTERNET AND PLACE IT IN C:>FLASHTOOL>FIRMWARES BUT BEFORE THAT REMOVE ALL THE OTHERS FILES IN THAT FOLDER.
3. OPEN FLASHTOOL AND CLICK THE FLASH BUTTON.
4. TURN OFF UR PHONE FOLLOW THE ONSCREEN COMMANDS.
5. UR PHONE SHOULD NOW BE WORKING AFTER IT IS FLASHED.
TO ROOT :
1. DOWNLOAD CYDIA IMPACTOR TOOL FROM GOOGLE.
2. RUN IMPACTOR.EXE AND CONNECT UR PHONE , THEN CLICK USB>DRIVER SCAN THEN CLICK START.
3. IF U SEE SU OR SUPERUSER IN UR PHONE THEN IT IS ROOTED OR MAYBE DOWNLOAD IT GOOGLE PLAY.
4. TO MAKE SURE UR DEVICE IS ROOTED DOWNLOAD ROOT CHECKER FROM PLAY STORE.

flash the stock firmware first...
for that
You must run flash tool first.
power off phone (take out battery and insert again).
connect phone and pc with usb cable while
press and hold volume down button.
the illumination bar will become green.. and
flash tool will recognize device connected as flash
mode...
then flash the firmware....
flashtool :
http://www.flashtool.net/download.php
stock firmware :
https://drive.google.com/uc?id=0Bzvi...xport=download

video guide on how to flash firmware :http://m.youtube.com/watch?v=KmLqd-a...ient=mv-google

For rooting Xperia u :
just flash the prerooted kernel using flashtool..
kernel link :http://forum.xda-developers.com/xper...ernel-t2299748
just extract the Zip file..
search for the kernel.elf or boot.img
(if it is kernel.elf, just rename file to kernel.img)
and flash in fast boot mode...
for fastboot mode :
power off phone (take out battery and insert again).
connect phone and pc with usb cable while
press and hold volume up button.
the illumination bar will become blue.... and
flash tool will recognize device connected as fastboot mode...

press THANKS if I helped you.............
