    I was wondering what WBFLASH actually does... Here are some findings...
    wbflash.scr is an encrypted parameter file, decrypted data looks like this:
    Example 1:
    Code:
    [BIOSVER]
    R0174J3
    
    [CMDLINE]
    WinPhlash /BUT_PROG_OFF R0174J3.WPH
    
    [FILES]
    PhlashNT.sys
    R0174J3.WPH
    WinPhlash.exe
    
    [CHECK]
    2
    
    
    • ?????J3 [END]

    • Example 2:
      Code:
      [BIOSVER]
      R0052N7
      
      [CMDLINE]
      WINPHLASH.EXE /SPI /BBL /REMOTE2 R0052N7.WPH
      
      [FILES]
      R0052N7.WPH
      WINPHLASH.EXE
      PhlashLc.dll
      PhlashNT.sys
      Phlash9X.vxd
      WBFLASH.exe
      WBFLASH.scr
      
      [CHECK]
      2
      
      
      • ?????N7 [END]


      • Wbflash requires Sony Shared Library to be installed, which includes the DMI driver.
        Wbflash uses it to get DMI Info.

        WPH:
        Part Table included at the end of Sony WPH files describes the flash chips and has a signature PARTTBL.
        Platform descriptor is usually "VAIO " or "VAIO1".

    How did you decrypt it? I would like to decrypt (and maybe re-encrypt) mine so I can get my BIOS to flash..

    Can you just use WINPHLASH?
