    Hi guys, i don’t have many experience with Android OS, and i ask your help to do this update for my KB2 PRO.
    I downloaded the firmware, extract the zip file into a USB flash drive with only the four file (dtb.img; factory….aml;; recovery.img) but when the box started in recovery mode say this error:

    Finding update package..
    Opening update package…
    E: failed to moan / udisk (No such file or directory)
    E: failed to map file
    Installation aborted

    I tried also to install this update from microSD card, but it say the same error

    I have the same problem. It doesn’t work. If someone know what’s the problem please help us.

    Update with free Rashr app from Play Store:

    Rashr app Click >>> Recovery from Memory, load .img File and follow the instruction.

    It works!!!

    Important for emergencies: It is best to create a TWRP backup first and mark all the hooks in the backup.

    Create Boot SD Card with Amlogic_SDcardMaker_BootcardMaker_burnBootCard_v1.0.1

    You need the following files:
    1: BootcardMaker.exe
    2: langu.ini
    3: u-boot.bin

    You need TWRP.img S912 for Android 7.1
    Rename TWRP.img to recovery.img

    SD card:
    1: starts the boat card maker
    2: Selects the SD card at the top.
    3: Hook on partition Yes
    4: Below Open File u-boot.bin
    5: Click Make

    Format Fat 32 done

    Finally, you copy the TWRP file with the new name recovery directly to the SD card just as pure.

    SD card boat:

    Turn off the Yoka KB2 Pro completely, insert the SD card, hold the front button. Turn on the box and when the Yoka logo arrives, wait 5 seconds, slowly count to 5 and then release.

    Good luck.
