    Get a working phone of the same type as the bricked one and back it up using mtk droid tools; you'll find boot.img inside the backup folder or you could use partiton manager to dump a boot image to the SD card of the working phone

    Is the custom recovery.

    It might not be the right oen for your build. You can also follow these steps in fixing it.

    STEP 1: Extract the ROM that you have downloaded for your device.
    STEP 2: Open the folder and go to META INF/com/google/android.
    STEP 3: Open Update Script file via through notepad.
    STEP 4: Here, you will get a full-fledged script. Delete the entire line starting from “assert(getprop(“ro.product.device”)…..” until you get a semicolon “;”.
    STEP 5: Save the file.
    STEP 6: Now, you need to make a zip file consisting of all the files that you extracted in the first step.
    STEP 8: Copy this new zip file on your SD card and then flash it on your device.

    Hopefully, ROM will be flashed successfully.

    If you can't follow this tutorial above, just follow this article properly and get it flashed successfully.
