For 4.1.B.0.587 see 3rd post!

Special thanks
BluechipJ for the video, AeonWorld for the pro root tutorial, shantusingh for being the first one to use and post a root method for 4.0.4, buzzinkeegs for inspiring me to create this thread

After i used buzzinkeegs's tutorial to root my Arc s i thought to put the 562 kernel in the 431 FTF, so the only thing you need to do is rooting with OneClick root exploit for the 4.0.3!

thanks BluechipJ for this amazing video! :D


For Xperia Arc/S:

1) flash the ready to root 4.0.4

if you already on 4.0.4 you can just flash the 4.0.3 kernel: http://www.mediafire.com/?twn09p8ekug46f7 thanks to sathurnn

note: you might get errors after the reboot, don't worry, this is normal and step 3 will fix that.

2) root your Arc/s with this:

Back up links for 4.0.4 and 4.0.3 Kernels [Only for Lt18i ARC S]

i didn't try that, you might loose your root.

First of all thanks a lot to Overlo4d for this trick. Now I have edited my post a little bit just to share how i did the root.

Please remember I have an Lt18i [ARC S]


* I flashed the 4.0.4 [0.431] firmware from here. = http://forum.xda-developers.com/showthread.php?t=1583010
* I flashed the kernel of 4.0.3 [0.562] firmware. AND Kernel Sources :- http://www.mediafire.com/?u4yyu9066gloxxu
* Then I rooted using the following script by DoomLord. AND Root Source:- http://forum.xda-developers.com/showthread.php?t=1601038
*Then I flash back the kernel of 4.0.4 [0.431] firmware. AND Kernel Sources:- http://www.mediafire.com/?qx8gi3imbgqlxh5

I have a locked bootloader and am new to android.
I've just upgraded from 2.3.4 to 4.0.4 via sony update service.
Please tell me how to root my device (Xperia Arc) using the file in the post.

Worked for me. I had a lot of errors after flashing the old kernel btw. But after rooting with the one click program I flashed back the new kernal.sin and loader.sin and now I don't get any errors anymore. I removed all bloatware and ads using root ^^
