    DENOVA Novatek FW unpacking script.

    DENOVA script v0.8. download | mirror | mirror

    Unpacks single- and dual-partition Novatek FW files.
    Unpacked file(-s) will be saved at /DENOVA folder.

    Supported Novatek firmware types:
    • 2 BCL partitions in a row.
    • 1 FullComp BCL partition.
    • 1 PartComp BCL partition.
    Usage: denova.bat <filename>
    Example: denova.bat FW96660A.bin

    List of extracted files for firmwares, containing two BCL partitions:
    1.bcl - Original 1st BCL partition without the footer (tailing 40 bytes)
    1.bin - Unpacked 1st BCL partition
    2.bcl - Original 2nd BCL partition (IQ) with 1st BCL partition footer in the beginning of the file

    Firmwares, consisting of one BCL partition will be extracted to 1.bin file.

    Run GETBITS.BAT to extract the bitrate values and offsets. Note: Only NT96660 firmwares are supported now.

    Run DUMP2BIN.BAT to convert SPI-flash dump to firmware update file. Works with NT96660 4 and 8 Mb dumps.

      I've found a bug/problem: DENOVA only works with FullComp firmwares.
      This happens with NonComp (BCL1 @0x000b0000)
      Code:
      DENOVA Novatek firmware unpacking script by nutsey for GoPrawn.com v0.3

1 partition found.

decompress tempfile.bin to DENOVA/1.tmp...
Input file: 2574288 bytes
Output file: 0 bytes
error: end offset is lower than start offset
1 errors occurred.
error: no such output file: DENOVA/1.bin
1 errors occurred.

          Thanks! Hope you will have time to make support for Elephone EleCam Explorer Elite 4K

        Hello. Trying to unpack firmware from Elephone EleCam Explorer Elite 4K because it has too low bitrate. In the begining of .bin there is such text: BCL1 ... NT96660 ... 1000000020100701 but ntfwtool.exe
        crashes on unpack. (using DENOVA script v0.5)

        "
        error: end offset is lower than start offset 1 errors occurred. error: no such output file: footer.bin 1 errors occurred. "

        Firmware link:
        FW: 2017-01-06: https://mega.nz/#!80hW3ZjY!0xBdK-rJU...NCp6v0zEMBo-o8
        Loader 2017-02-08: https://mega.nz/#!dwIxDbIY!ag__fyN0PTRlASL2izsZJWa_yDtIBiB53IRHB2q ur20

        Can you please explain me if I have found some text which is probably responsible for bitrate, how to find here ordinary digits? What should I change?
        Thanks in advance.

          Run GETBITS script with 1.bin in DENOVA folder and you'll get OFFSETS.TXT from which you can learn all bitrates offsets.

        nutsey, thank you. I've seen instruction. The second problem is that I see hex values of bitrate but I don't know in what form is it and what values to change. I understand that I'm newbie and you don't have to explain me all stuff of reverse ingeniering but I guess this task is not super hard. I'm trying to convert hex to dec with windows calculator. Is it right?

          Real values are divided by 2, stored in reversed ordered hex.

        Ok, I almost found what is what. Hex to dec helped. Stil don't understand bitrate values.

          Ok. The first bitrate stored as 0x00E02E -> reverse it -> 2EE0 -> dec -> 12000 -> the real value is x2 as I said above = 24000

              Was successful on other env. Probably some framework libs were missed.
              Thanks.

              Are there any plans to implement bitrate editing scripts?

              I get the same error with the Firefly Q6 firmware https://drive.google.com/open?id=0Bx...VRBSG1NZVhwWTg
              What did you change to get it working?

              Just run under my working VM. Did not try to ivestigate the issue source.

            GETBITS script was updated to v0.2. Now you can get more informative data layout with bitrate values in dec.
