This is a full step-by-step guide (w/ video) for rooting Sony Ericsson Xperia Arc. You’ll be required to unlock your phone’s boot loader first to get root access, so proceed only if you’re willing to unlock boot loader or if you’ve already unlocked it. [warning]The methods and procedures discussed here are considered risky and you should not attempt if you don’t know completely what it is. If any damage occurs to you or your device, we won’t be held liable. You only will be responsible — you’ve been warned. Okay![/warning]

Unlocking the Boot loader [IMPORTANT!]:

To be able to root your Xperia Arc. You’ll have to first unlock the boot loader on your phone (If you’ve already unlocked boot loader on your phone then skip this step). Below is the link to our simple step-by-step guide: Simple guide to Unlock Boot Loader On Xperia Arc, Play, Neo and Pro

Instructions for Rooting Xperia Arc:

Video guide:

The video shows rooting of an Android 2.3.2 ROM, but rooting instructions are similar for Android 2.3.4 ROMS as well, so you can safely refer to the video below, but do follow the instructions carefully.

  1. Go to Settings page on your phone, scroll down to bottom of the screen and select “About phone”, now check your “Model number” and ”Build number”. And then choose an appropriate file for your version of phone from the link below:NOTE:The file given below is rooted system image for Android 2.3.4 [4.0.1.A.0.283] Global firmware, and it’s highly recommended to have the non-rooted version of the firmware installed on your phone before flashing the root image.So if you’re not already on an Android 2.3.4 [4.0.1.A.0.283] firmware, then follow the link below to upgrade your phone to the latest firmware using ‘Flashtool’: Complete guide on how to flash “.ftf” firmware files using Flashtool

    Below is the Android 2.3.4 [4.0.1.A.0.283] rooted system image:

  2. Download the following file, named “fastboot_with_Android_USB_file.rar”, from this link.
  3. Switch OFF your phone. Wait until it vibrates to ensure that it has completely switched off.
  4. Now extract the file you downloaded in Step 1.2. You’ll get two folders — “fastboot” and “usb-driver”.
  5. Into the “fastboot” folder you need to cut/copy/paste the file you downloaded in Step 1 (See the video for reference).
  6. Now pick up your phone (it must be Switched OFF) and hold the “Menu” key (the key at the bottom right side of your phone), now while holding the Menu key, connect your phone to your PC with an USB cable.
  7. Once connected — the LED light near the phone’s USB plug will turn blue. If it doesn’t — repeat the Step 6.
  8. Open the “fastboot” folder that we extracted in Step 4.
  9. Now hold Shift and press mouse right click (Shift + Mouse Right Click) anywhere on the empty white space inside the “fastboot” folder. And then select “Open command window here” from the context menu (See video for reference).
  10. Type/Paste the following line in the command prompt window:

fastboot flash system LT15i_4.0.1.A.0.283_Generic_Global_system.img

And hit Enter.

  1. Now wait for the process to complete. Command prompt will show a “Finished” message when it will be completed.
  2. Once it’s done, disconnect the USB cable from your phone and Switch ON your phone.
  3. Inside the app drawer check for “Superuser” app. You’re all good if it’s there, but if it’s not in the app drawer, then search for it in the Android Market as “Superuser” and install it.

Now to ensure that your phone have root access, try some apps that require root access. I tried “Titanium Backup” and it worked well.

Many thanks to XDA member ‘rahul.pillai’ for providing the rooted system image.

    I think I’ve messed up somewhat. I installed CWM and Cyanogen Mod7 but that doesn’t like the ver 3 firmware. Now I’ve tried to install this version 4 but it’s complaining that the partition is too small when flashing the boot partition. Is there any way I can resize that?

      Factory reset your phone. It may help.
      Remember it’ll erase all your data, so take a backup first.

      • Dj_rc

        nop didnt work iv’e the same problem any more soluttions???

        • http://www.theandroidsoul.com Shivam

          Flash the latest firmware again using flashtool, then check if your problem is solved, if yes, then flash the root image.

          • Dieter_vsx

            I know what’s the problem:
            I downloaded a 1.65GHZ overclock from this site
            but it was for 2.3.3 so it’s wrong kernel or so, if i got it right, cause it does work with only root
            could someone make an overclock for the 2.3.4? or am I able to downgrade to rooted 2.3.3?
            thanks for your help!

          • Dj_rc

            the problem was that i was flashing the root image on the 2.3.3 (older) so i had to flash the .tft file of the new update and then the rooted img now every thing is ok 10x anyway :)

          • http://www.theandroidsoul.com Shivam

            You wouldn’t have faced the problem if you’d read the instructions carefully. Anyway, glad you got you sorted it out :)

    • http://www.theandroidsoul.com Shivam

      Maybe your phone’s can’t be unlocked. Where do you live? And from where did you purchased your phone?

      • Cebotarileonid

        I purcase it from Canada,i live in Moldova

        • http://www.theandroidsoul.com Shivam

          Is it carrier locked?

          • Cebotarileonid

            no,what did you mean ?

          • http://www.theandroidsoul.com Shivam

            I meant, is your phone locked to a single carrier or it works with just any SIM?
            Actually, a carrier locked phone may have permanently locked bootloader.

          • Cebotarileonid

            it works with any sim….

          • Cebotarileonid

            the blue light still not appear and i can’t go after step 6…help please

          • http://www.theandroidsoul.com Shivam

            I hope you’re holding the “Menu” key while connecting the USB cable.
            I really can’t understand why it isn’t working for you, sorry.

          • Cebotarileonid
