[Arc/S] [PRO] Root for 4.0.4 ICS Update [4.1.B.0.431+4.1.B.0.587]

OverLo4d · May 31, 2012

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!

For Xperia Arc/S:

1) flash the ready to root 4.0.4

for the Arc s:

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:

So do I need to flash back 431 kernel at the end?

yes

hackdima · May 31, 2012

Thank you very much! =)

Pandemic · May 31, 2012

i think thats the easiest way to root is that if you have rooted 562 then do the OTA (over the air) then you will keep root also

OverLo4d · May 31, 2012

i finished the FTF for the Arc (lt15) and i'll upload it tomorrow!

It works!

After Flashing 4.0.4 ftf, I flashed the 0.561 kernel for root. And after rooting i flashed back the original kernel of 0.431 again.

The root is still there.

great! i'll make a second ftf that will flash only the 431 kernel.

OverLo4d · Jun 1, 2012

now available for the Arc!
please reply if it works well.

muzadull · Jun 1, 2012

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.

jr486 · Jun 1, 2012

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 ^^
