Important Notice
  • If you get stuck at 80%, then check that the file path to this tool doesn't contain any spaces or strange characters e.g if your username contains a space then copy the tool to your C:\ drive or re-download a fresh copy of the tool
  • This tool was doesn't work with all dz files, it works specifically for those that fail to extract when using LG Firmware Extract Tool due to dz header error
  • For those extracting an dz firmware for an mtk device, preloader from the firmware needs to cleaned up before flashing; see steps 12 - 16 @ WWR_MTK (preloader analysis)
  • If you get dual files for each partition after extracting dz, this means your device has A/B partitioning, so the files labelled as *_1 e.g boot_1 is meant for the B slot
  • Credits for goes to mcmilk & thecubed for the libraries used
  • This tool fixes dz extraction error for those who encounter something like
    Code:

    Exception on extract partition file Ionic.Zlib.ZlibException: Bad state (incorrect header check)
       at Ionic.Zlib.InflateManager.Inflate(FlushType flush)
       at Ionic.Zlib.ZlibCodec.Inflate(FlushType flush)
       at Ionic.Zlib.ZlibBaseStream.finish()
       at Ionic.Zlib.ZlibBaseStream.Close()
       at Ionic.Zlib.ZlibStream.Dispose(Boolean disposing)
       at System.IO.Stream.Close()
       at WindowsLGFramwareExtract.Form1.DZExtractBackprocess.extractDZFlle(ArrayList contents) in K:\Working_PROJECT\WindowsLGFramwareExtract\WindowsLGFirmwareExtract\Form1.cs:line 464
