How to root your Sony Xperia Arc S with Android ICS 4.1.b.0.587(4.04) or upgrade from any previous version

With this manual, you will learn how rootear or update your version of Android to the latest 4.1.b.0.587 en tu Sony Xperia Arc S. In my case, I had to start from the B option, since from Yoigo it has not yet reached the last update and my patience has its limit.

This tutorial will help you if you are in any of these situations:

A- I Android 2.34 and I want to upgrade to ICS 4.04, 4.1.B.0.587 with root included

B- Tengo Android ICS 4.03 with Kernel 4.1.A.0.562 and I want to upgrade to the last 4.04, with Kernel 4.1.B.0.587 and root.

C- Tengo Android ICS 4.04 with Kernel 4.1.B.0.431 and I want to upgrade to the last 4.04, with Kernel 4.1.B.0.587 and root.

D - I have Android ICS 4.04 with Kernel 4.1.B.0.587 and I want to give the root!!

Updated 19-04-2013: New method for rootear your xperia ARC, Xperia Arc S and S in 1 click which replaces the D option this manual.

 

COMMON TO ALL PROCEDURES

Like entering service mode: It goes mobile, They wait 5 seconds, holding down the back button without releasing, and a second later the USB cable plugs (which will be connected to the pc), and the green LED lights. As you see, I have not pressed the button on the phone at any time.

– Turn off your antivirus Windows when you start with this, especially Kaspersky.

– Get off the full Pack (all inclusive less USBFlashdriver.exe) from here: Xperia arc s.rar .

– Get off the Pack Option D (NO It includes flashtool, android sdk or anything other than Option D, you go down of the links below separately).

Updated broken links 25-10-2016. Install in this order ....Pc companion, Android SDK WindowsMirror (once installed, then you have to install Android SDK Platform-Tools, thanks Julian), USBFlashDriver.exe, (thanks Rafael) Y FlashTool, then copy the root script in a folder on the Windows desktop.

– Once installed Flashtool, copy inside the folder c:\flashtool firmwares all files that start with LT18i_4 ... ..ftf ...

– If fear it will come sometime or something is wrong so it is ....you always have the option from the PC Companion "repair phone", that you put the last clean version that you have installed before. From here, and you can re-start the tutorial.

– Important note: No software update from PC Companion erase your installed applications.

Updated 12-2-2013: If gives you error to start the flash goes off C:\Flashtool\devices\LT18\loader_unlocked.sin (The system can not find the specified archive), just get off an old version of flashtool from the web, in paragraph previous releases. The 0.9 release this ok. thanks Cris !!
