    do i need to unlock bootloader from sony website before this process you have mentioned or does the process unlocks it for me?? I am new to this and would appreciate a little guidance

  • veliouras

    please note tha your link to super su.zip file does not work

    • onoff

      if you manually cut the first part of url it will work!

  • onoff

    it is not possible to flash kernel in fastboot mode (point 8 of your guide), flasher says:
    FAILED (remote: The Device must be rooted first)

    • Usama Mujtaba

      @disqus_EKXlBXsghj:disqus that means you must unlock the bootloader of your device first.

      • Too much to lose by unlocking the bootloader; no alternatives?

        • @KoKaSparK:disqus if unlocking bootloader is the requirement, then there probably is no other way.

  • Julisosns

    superSu link ????/

  • Usama Mujtaba

    Here’s the working SuperSu link: http://download.chainfire.eu/supersu

  • Faraz Kharral

    your every single instruction is 100% correct bro…really appreciate your effort 🙂 GOD BLESS u
    kindly also post some articles about installing (efficient) custom roms for this phone like 4.4 kitkat

    • Usama Mujtaba

      @farazkharral:disqus that’s a great suggestion, I surely will do the research and make a post on that. Thank you for the appreciation, stay connected with us.

    • Sohail Ahmed (AOKP DEV)

      What? 100% correct? Oh boy, whats wrong with you people. Okay ill point out the flaws.

      Backup all your apps / data. If you’ve rooted your device, use Titanium Backup to do so. Follow the full guide here.(Why the hell will our device be rooted when this guide is about rooting itself. Everybody is looking at this guide to root the device but according to OP, we have already rooted our device.)

      As soon as SuperSu.zip is flashed, turn off your device by keeping the power key pressed for a while or pulling out the battery(OP Xperia SP doesn’t have an open battery :/)

      As soon as the system is mounted, choose install zip > choose zip from sd card > SuperSu.zip that you placed on your phone in the 2nd step and flash it. (It is not necessary to install SuperSU)

      • Usama Mujtaba

        @sohailahmedaokpdev:disqus Its a matter of acceptance buddy. We live in a word where we point mistakes and waste our times, that is not actually meant to be done. The post mentions that its a precaution, only if you;ve already rooted your device. Why the hell do you need to point it out, I guess you gotta go back to your primary school and learn the English. 2ndly, we mention the steps with the best possibilities. Learning a few things doesn’t make you someone superior, and the world is not moving ahead because of such idiots, who are always trying to pull the legs. Step mentions “OR” or means the step is ultimate for guides for Samsung and other devices on our site. IDIOT!!! Enough Said!

          Sohail Ahmed (AOKP DEV) and the so called, FAKE AOKP DEV. Not found on the AOKP team link: http://aokp.co/team/

      • @sohailahmedaokpdev:disqus
        Well if he’s saying everything worked for him just fine, then there’s no need for you to deny it, out of nowhere.
        Secondly, about apps backup, the writer means if you had root in previous firmware, make a backup of those applications and restore in new firmware. I do that all the time using Titanium Backup 🙂
        And in this case, SuperSU is required, since the recovery alone does not install it and I have tried to install recovery, use its root option and then install SuperSU from Play Store, didn’t work.
        Anyone can make a mistake (Since we are so lucky to be humans :D)
        Since you are a Dev (I don’t see why you have to publicize this) but developers tend to be more of a helping hand than being sarcastic and “not appreciating” if someone’s helping someone else. I hope you understand my point. 🙂

  • vasu

    Can i install this CWM in 12.1.a.1.205??

    • Usama Mujtaba

      @disqus_HxQuqxkwS0:disqus this is a method to root only, CWM is not available, however you can use the CWM steps in this guide to use it for a short time, after that you can flash a stock kernel.

      • vasu

        I was asking for CWM for installing Cyanogenmod 11 can i install it through it..
        Or there is other method also.. Like installing it from flashtool… If yes can you tell me how??..

        • Usama Mujtaba

          @disqus_HxQuqxkwS0:disqus give it a try, i think you can install through this, because CM 11 will have its kernel.

  • Patrick

    Broken dowload supersu.zip

  • Patrick

    Sony FlashTool, is a program of sony? Please, this is what I doubt.

    • Usama Mujtaba

      @disqus_NuqxKQmQOQ:disqus No. Flashtool is an unofficial program.

      • Patrick

        where do I download it?

      • Patrick

        is emma?

  • MahmodDoumany

    It does work
    Tnahks..
    Note : BootLoader should be UNLOCKED

  • parin randeri

    I hv rooted my Xperia using above method. Now in about the phone build number is showing 12.1.A.1.205 which is latest updates by Sony but in update center system update showing to 12.1.A.1.205 which is already installed ..Now, When I connect to PC Companion it show your phone version 12.1.A.1.201 & update to 12.1.A.1.205 … confused here already in about the phone build number showing 12.1.A.1.205 & pc companion showing 12.1.A.1.201. Now, from update center I tried to download & install update version then “system update fail” error shows..

    Anybody can Help here???

    • @parinranderi:disqus if your phone and the connection is working fine, you can simply ignore what PC companion is telling you. There is no need to worry about it, if there comes an update in future you can flash it using flashtool.

  • @KoKaSparK:disqus http://Flashtool.net

    • My SP’s Version : C5302 12.1.A.1.205

      1. Downloaded unofficial flashtool.
      2. installed drivers for flashtool.
      3. “Reboot Device into Fastboot Mode.” didn’t work, so did it manually => by pressing volume up key -> blue light after USB plug-in.
      4. When I tried to push “DoomLord Advanced Stock Kernel.elf“, it said Error: device needs to be rooted.

  • Malik Shahid

    hi bro, my xperia sp c5303 android 4.3 is all good, but having problem with its upper touch, about a month back, but in between when i connect it with the pc and touch it after that touch works fine for a day, then again the same problem, now that option is not working as well. could you please tell me the reason and the solution of it.
    thanks in advance looking forward for your reply.

    • @disqus_m3X3LUU5vL:disqus try flashing a new and clean stock firmware on your device, it might get fixed.

  • Nace

    The link doesn’t work for SP_DooMLoRD_AdvStkKernel_FW-201_v03.elf

    http://doomlord.xperia-files.com/download.php?dlid=U1BfRG9vTUxvUkRfQWR2U3RrS2VybmVsX0ZXLTIwMV92MDM=
