    Tried the above method with my KFHDX8.9 (with FW version 8.5.1) but when executing the last command I got the following messages

    Device detected: KFJWI (IMM76D)

    Attempt acdb exploit…
    KFJWI (IMM76D) is not supported.

    Attempt fj_hdcp exploit…

    Attempt msm_cameraconfig exploit…
    Detected kernel physical address at 0x80008000 form iomem

    Attempt put_user exploit…
    write: No space left on device

    Help would be very much appreciated. Many thanks

    Is it possible to root the KFHDX 8.9 with firmware version 8.5.1? I have tried a couple of methods but the Kindle runs exceptionally slowly afterwards and I had no choice but to do a Factory Reset. Many thanks for any help/advice.
