{
    "master":{
        "version":"1581318174",
        "url":"https://www.custurl.com/download/payload.bin",
        "description":"This is Note for Master, upgrade to version 1581318174",
        "FILE_HASH":"KrcnrqCzAIcnnjc1ysoVY0jpIgDPsVPB9oGjjyg34fI=",
        "FILE_SIZE":411430579,
        "METADATA_HASH":"ePssh8AaT6JuDcQznmqq/kHi+ZwSUr2tBXEXwq4xLnQ=",
        "METADATA_SIZE":110793
    }
}

ABOTAUpdate App will compare "version"(the value of ro.build.version.incremental)
from this content and then use TAG "url" as downloading path.
If your firmware version is NUM_VERSION_A and then you will download version_a+.bin as your new firmware.
If your firmware version can't be found through JSON file, and your firmware version is older than NUM_VERSION_B,
then you will download "master" url specified version_b.bin as your new firmware.

Sample Content of SB30.json

{

    "master":{
        "version":"NUM_VERSION_B",
        "url":"https://www.custurl.com/download/version_b.bin",
...
    },
    "NUM_VERSION_A":{
        "version":"NUM_VERSION_A+",
        "url":"https://www.custurl.com/download/version_a+.bin",
...
    }
}
