As we all know last night Sony rolled a lot many firmwares for it’s beloved Xperia Z Series phones. Xperia Z, ZL and ZR were updated on same Android 4.2.2 10.3.1.A.0.244 firmware with same kernel version and baseband. The most serious concern for the update was that, Sony has patched the perf_event exploit which was used to root the devices. But not issues.

Legendary XDA Developer has found a solution to Root Xperia Z, ZL, ZR Android 4.2.2 10.3.1.A.0.244 firmware by his new DooMLoRD Easy Rooting Toolkit v18.

    The programme said
    Device detected : C6603
    C6603 is not support

    then my phone reboot accordingly and resumed normal.

      do you have XZ C6603 ? or you flashed the kernel of C6603 on C6602 ?

  2. Liviu August 2, 2013 at 3:03 pm - Reply

    It worked for me on C6602. When I flashed XperiaZ_C660X_KernelOnly_10.3.1.A.0.244_BE.ftf, I got an error. I closed the flashtools and I reopened it with “run as administrator” option in Windows 7 and everything was perfect. I was on IOS and now I am a very new user of android, but it was easy to root my phone, although I was a bit… scared. No data was lost, and my Xperia Z is running perfectly. Thank you.

      Thanks for posting it :) but our original tutorial was even from XDA member DooMLoRD, so it is the same procedure if you have got kernels for your phone.

      Will you please share us the Kernels which you used for rooting your phone ? it will help other uses, we will update in post..

    For some reason, the PC companion software won’t go any further when following the 5-step instructions for the update. I get stuck at step 2 named “prepare”. Did any go through the same problem? Is there another way of flashing the .244 firmware with flashtool instead?

    • moderatto August 6, 2013 at 8:35 pm - Reply

      I managed to switch to a different USB port and began to work. Thanks anyway.

    • Anurag Kumar August 16, 2013 at 11:50 am - Reply

      which files you flashed ??? above files are only and only for Xperia Z, it is written.

    now..what can i do???

    • Anurag Kumar August 16, 2013 at 11:55 am - Reply

      as you flashed the wrong kernel on your phone your phone will not start now i guess…
      Are you able to boot into recovery mode ? If no, then i am afraid you need to flash back the firmware again on your phone…

      We put warning above that files are only for Xperia Z, why did you flash them…it was written that for ZL and ZR on should flash their respective kernels.

  13. JOHN August 16, 2013 at 11:59 am - Reply

    i’m confused…
    okay…how to into recovery mode???

      press power button and as soon as you see sony logo, keep pressing “volume up” button…till you see recovery screen

      only solution left is either you update your phone via SUS again or flash the ftf of ZL again.

    how?please help me

    • Anurag Kumar August 16, 2013 at 12:21 pm - Reply

      Download Sony Update Service Software and then install it. Run it. Now connect USB to PC and now press Volume down button, hold it don’t loose it and then insert usb cable into phone > as soon as phone is detected by SUS, it will update it.

      If above method fails, try this below one…

      download this ftf file – https:// docs.google.com/file/d/0B3FdYj1Oo3PPb3FkRElFcmNRc2c/edit

    for those who have suffered from bricking their phones and are unable to boot after flashing the wrong kernal. I personally bricked my phone by flashing zl kernal instead of z. i tried to turn it on… the only response was vibration. I aslso tried flashmode.. no luck. it is not detected by pc either by volume up or down or both. anyways after many tries, i managed to revive it, here’s what i did.
    1- got to support zone in sony pc companion, hit update.
    2- hit repair my phone/tablet.
    3- when it is done preparing and downloading, choose your device from the list.
    4- when it asks to press volume down and plug in usb (we already know it doesn’t work) plug in ur dead phone via usb and hold down both volume buttons and power button until it gets dedicted by sony pc companion.

    the phone will update normally and will boot up.

    since doomlord didn’t mention the details of kernals, you should have found the kernels and put the link here.
    its just to ensure that your tutorial should be one stop shop for xperia z/zl users and they shouldn’t go through xda again to find info.

    I think to up the ante, sony should start selling phones with customized hardware and software with root access as default(customer should be able to give his requirement).they can charge users for software they want to use and provide the support .
    they should start building loyalty by providing exchange offers on existing sony phones for new models.
    just a thought….

    Hi Anurag.
    i was going through the link :forum.xda-developers.com/showthread.php?t=2349656 for installation steps:

    i have some questions:
    1. i have already installed the kernel for .244 after rooting. can i install directly by putting the rom in the Internal storage and flashing using cwm intead of dual nut recovery as mentioned
    2. since i don’t have external card, i have cwm installed in internal storage; so during the Wipe Data, Cache and Dalvik Cache,if something goes wrong during installation, can i still go back to cwm recovery through the volume key and restore the backup?
    thanks in advance

    • Anurag Kumar September 15, 2013 at 5:08 pm - Reply

      Install like this:-

      Root your device
      Flash back new .244 kernel
      Install cwm recovery the link i gave to you.
      Now copy the honami rom zip on your internal memory.
      wipe cache , dalvik , and data only if you want.
      Install rom zip in recovery.

      Done flashing rom.

      Install rilj add on to avoid call wakelock .

    also can u just give me a brief how it helps?
    I have been searching all over to understand.

    • Anurag Kumar September 15, 2013 at 10:05 pm - Reply

      Check all ads on on the first page given….Then spot a word RILJ there, that add on you have to flash.
      In this ROM, call app is on all time, means if you are not calling or you phone is in idle state then also call app is on ( means you are on a call now and your batter is exhausted a lot )

      So to avoid this call wakelock issue, we flash back the XZ/ZL call features.

      Yes this happens sometime, try rebooting phone than try….if it don’t show up then i guess no issues. ( i have no idea why this happens, it happened with me too. )

      You can restore your present ROM via PC companion again and back up via PCC and backup all apks via avg antivirus.

      While flashing ROM, do flash RILJ add on, 48 dpi add on, remove chinese keyboard and handwriting apk to remove bugs from keyboard…will stick a post on this rom, many people are asking about it.

    Hi Anurag

    I didnt try to call as i felt that it was a mess and realized that the rom is not working; I didn’t check for any thing working since it showed no other applications except the walkman, album, converter, file commander etc. hence i reverted back to the stock ftf.

    i think its not working on xperia zl and has some compatiblity issues

    I earlier asked for help rooting my xperia tablet z, well I am happy to say after an initial problem with bootloop which was scary, Well I now have it rooted on 4.1.2 firmware with all my games large data files installed on sd card with filemount(root) very happy and thinking about doing the 4.2.2 update in system updates but want to know if I do this will I lose root. There must be a way, I had to flash the 4.1.1 to get root access. Very happy so far tho now this tablet is even more awesome :)
