    When i select XperiaZ_C660X_KernelOnly_10.3.A.0.423_Generic_NL.f tf
    for flashing, a new window pops out telling me to unplug the device and press the “back” button. What the actual fuck? There are no buttons on the Xperia Z.

    • Rawad October 9, 2013 at 9:46 pm - Reply

      that’s (power + volume down) buttons for your device

    If you guys had any idea of how much trouble i went trying to find concise instructions on how root my device running 4.2.2 with build number 10.3.1.A.2.67 you would felt sorry for me haha.

    No, there is no back button however by pressing both up and down keys together before you plug the cable in it enables the flash to execute ok?

    I did notice my device going into Airplane mode during this process but simply turning it enabled the radio again.

    Thanks guys

    Good work

    In the end after 10h struggle i succeeded to root ZL c6503 2.67

    Hi Anurag.

    “Xperia ZR uses should also do the same.”

    Does that mean ZR and ZL share the same kernel? If so ZR users should have no issues using ZL kernel?

    Please update. I would proceed with rooting once i get a confirmation.


    • Anurag Kumar October 6, 2013 at 8:39 pm - Reply

      Xperia ZR uses should also do the same – it means XZR users need to extract the present kernel from the ftf and the old kernel ftf themselves and just now i didn’t come across any kernel for XZR…

      Do not flash ever kernels of other phone’s doing that can brick your phone.

  7. Deepak October 6, 2013 at 9:38 pm - Reply

    Thanks for the response. That saved me from bricking my phone.

    Could you mention from where to extracts the kernels.

    I guess “C5503_10.3.1.A.2.67_RU.ftf” would have/give me the current kernel. And how about getting old kernel.

      This is the standard method of rooting after firmware .423 on Xperia z…don’t blame auhors when you did something wrong.

      Which phone you are on ? Which firmware ? Which kernel you flashed on…

      Try installing back the firmware via sony update service…

    Hello, I am using Xperia ZR Firmware 10.3.1.A.2.67 and I want to root my phone. Did you mean that to root the XZR one uses the kernel for Xperia ZL? So XZR and XZL are rooted using the same kernel?

    I don’t want to brick my phone

    Thank you for your post. Be blessed abundantly
