ICS Root XperiaIf you recently updated your Xperia firmware to Android 4.0 Ice Cream Sandwich and was wondering about root access then we’ve got some great news for you. A root toolkit has been released that will work for those on both locked and unlocked bootloaders. The toolkit will install Busybox (1.18.4) and SuperUser files.

The process itself is simple and involves downloading a file, extracting it using WinRAR and then clicking on ‘RUNME.bat’. It should work on all 2011 Xperia handsets running the official ICS update. See below for the full instructions.

Instructions to Root the Android 4.0 ICS Xperia update

– You must be running 4.1.A.0.562 firmware on your Xperia.
– All necessary drivers need to be installed on your PC (including ADB drivers). If you have any problems you will find the necessary drivers once you have installed Flashtool in the following location: ‘C:\Flashtool\drivers’. See our previous post on this for the download link.

    Amazing work.  Seeing as no-one managed to root the final GB release (.62) I was convinced a root solution for ICS would be impossible without unlocking your bootloader – glad to be proved wrong.

    And seeing how much bloat Sony are shipping with ICS rooting is the only way to get rid of it.

  • Xajel

    WOW, that was quick !!, I just commented on the previous blog post regarding the root

  • RaxaBoo

    Great. Will do this when the Neo update rolls out some time next century.

  • Asad Mulla

    Nice work XB. Keep the knowledge flowing.

  • Mike Martins

    I’m loving my Xperia neo v with ics rooted. The ics is visually more slow than gingerbread but I prefer to say it’s smooth :p even this way it’s much better than gb. It’s much more faster to do things and alternate between your apps. Loving it! The RAM seems better too

  • paul4id

    Indeed, .62 had great performance improvements, but I was REALLY REALLY having withdrawal symptoms from having root. I was unsure whether I’d upgrade to ICS or not as love the .62 performance but this has just sealed it for me!!! :-D :-D :-D

  • paul4id

    … Let’s just hope that the guys in Lund can tweak ICS further to give us the UI responsiveness of .62- fingers crossed!

  • M Usman

    rooting the arc now will be able to tell if the processor has been clocked to 1.4ghz right? if we’ve installed arc s software on it. if anyone does try this, do let us know if it has made a difference to the processor 

  • pegel

    Wow … great post, waiting for my xperia mini have update ICS too, after that I’ll get root from ICS,, very nice,,, 

  • Suhaib Haidar

    I’ve try do this steps, but the Xperia neo V is restarting without any changes.

  • Dude

    thanks, however I’m still thinking what to do. Apart from some justified lag some user sees it seems there are troubles w/ WIFI, browser & flash and some other headache I do not remember now. any other brave user out there w/ his/her witness?

  • is this for locked bootloader or unlocked?

  • ICS allows you to disable most apps you may deem as bloat actually, even core system apps

    I for one, have disabled the default browser from the App manager inbuilt into the system no need for a bloat freezer

  • Abhi

    Finally I’ll get rid of wise pilot:-)

  • Korriceg20

    wow spent so many days trying to root my xperia ray on ics im finally satisfied!!! THANKS GUYS!!!!

  • Now I just have to wait for my S to get the update and then im set!! DoomLord is AMAZING~!

  • Flashed ICS firmware onto standard Arc and then rooted as above . . . . after removing sopme of the ‘junk’ that i never use the phone is running like a dream, much smoother than before the update and the look of ICS i think is great. No lag or speed issues – dont delay . . . do this now !!

  • Robert Caldecott

    Installing Arc S software will NOT overclock your CPU! If you want to overclock you need to unlock your bootloader and install a different (not a Sony) kernel like DoomLord’s.

  • M Usman

    but isn’t the arc s kernel already overclocked to 1.4ghz. and after flashing with flashtool, you install the arc s kernel along with it. I was just curious

  • sceppy

  • Numan_mlik999

    thanks man i rooted my arc in just 2 min

  • Try the “Titanium Backup” app – lets you remove pretty much anything under the “Backup/Restore” tab. You can even ‘freeze’ an app to see if anything goes wrong should you remove it, if it does, you can simply un-freeze it.

  • JanaJackie

    Can u tel me the procedure to remove unwanted system apps

  • Mtweg12

    You can remove the unwanted apps by using Titanium backup 

  • alan

     wisepilot can now be uninstalled without rooting.

  • Or Root Uninstaller, I did that to replace the GB Music app that was inside the ICS ROM. Obviously you should take precautions when uninstalling system applications.

  • can u tell me the procedure

  •  you can remove system apps that you don´t need. You can use Link2SD or A2SD and use a second partition on your SD card to store your apps there and free phone space… and many more things

  • Naveendas99

    You will find it in the flashtool folder. All the necessary drivers. Have to manually install it.
    is this process also for rooting Xperia s or is it only for Xperia 2011 handsets

  • Badboys1901

    I did all the proces, but in the end, the SuperUser icon doesn’t appear on my mobile. Suggerences?

  • alumi

     4.1.B.0.431 has kernel of 4.0.4, and this kernel is still unable to root directly.

    General idea of what you need to do is:
    – Flash your kernel to 4.0.3;
    – Root it (4.0.3);
    – Flash your kernel back to 4.0.4.

  • Jeanine Baird

    Hi I know this is an old post but hoping someone can still help. I have a Sony Xperia Arc S phone, only a year old and quite attached to it but have problems with the limited internal memory and was directed here as part of the solution. However when downloading the files I get told the files are malicious and install is canned. Something about site possibly hacked. No idea where to find what I need otherwise so would appreciate any pointers if anyone is still following this post. Cheers
