คงไม่ต้องแปลให้มั้งครับ

STEP BY STEP GUIDE:
How to update the Sony Xperia S
to Android 4.0 Ice Cream Sandwich

NOTICE 1: This guide is for WINDOWS PC USERS, if you have a Mac I can’t help you

NOTICE 2: It doesn’t matter if your phone is rooted or not, bootloader unlocked or not, IT DOESN’T MATTER, this update has nothing to do with SIM unlock, bootloader lock / unlock, root, etc

NOTICE 3: This guide will update your Xperia S from ANY previous version to OFFICIAL SONY ICS ANDROID 4.0.4 and believe me: it is worth the update; HAT TIP TO SONY !!

NOTICE 4: Before asking, please read the questions and answers in the thread for many Frequently Asked Questions

STEP 1:
Download the Flashtool

You will find the installers here: http://androxyde.github.com/Flashtool/
Go to the “installation” tab, download Flashtool installer v0.8.0.0 and run it
Then download the v0.8.6.0 Update and run it
You will have a new folder on your PC: c:Flashtool

STEP 2:
Download the ICS update firmware

You will find several download options here: http://forum.xda-developers.com/show….php?t=1723610 (http://forum.xda-developers.com/showthread.php?t=1723610), just pick one and download it, then come back here
SOME NOTICES (I know you are gonna ask):
– I know it is “Generic Switzerland” (CH) but nevermind: it is plain Sony Generic and works fine for any region and has ALL the languages and keyboards
-The firmware is already prepared to be flashed via Flashtool in .FTF format. If the file you downloaded is .RAR then it is compressed (“zipped”) and you need to EXTRACT the .FTF with WinRAR (if you don’t have WinRAR download it from here: http://www.rarlab.com/download.htm)

STEP 3:
Let’s update the phone!

– Copy the firmware FTF file to c:FlashtoolFirmwares
– Go to c:FlashtoolDrivers and run Flashtool-drivers.exe to install the proper drivers
– After installing the USB drivers reboot your PC
– Run Flashtool
– Click the flash button (yes: the thunder icon up left)
– Select “Flahsmode” and click “OK”
– Select the “LT26 6.1.A.0.452” firmware and click “OK”, DON’T TOUCH ANYTHING ELSE
– Flashtool will prepare the files for flashing, just be patient
– A Window will pop up asking you to connect the phone in Flashmode with an old Xperia phone and instructions: ignore it, here is how our shiny new Xperia S enters “Flashmode”:

– Turn off the phone
– Press and hold the VOLUME DOWN key
– Keep it pressed, connect the USB cable to your PC
– Phone will have green LED indicating it is in “Flashmode”
– Flashtool will start flashing, now you can release the volume key

– Flashtool takes a couple of minutes, let it finish to 100%
– Disconnect the USB cable
– Press the Power button to turn on your phone
– The first boot takes a while, don’t worry let your phone prepare your Ice Cream Sandwich
– Have fun !!

PS1: PLEASE REMEMBER TO SAY “THANKS” to Bin4ry (for the FTF firmware) and Androxyde (http://forum.xda-developers.com/showpost.php?p=27692994&postcount=1) (for the Flashtool)

PS2: And the usual disclaimer, of course: Follow the steps and be careful, I am not responsible if you brick your phone, burn your house or blow your PC by following this guide; I am just sharing what I did to update my own phone and it worked for me
