Hi all, I have a HP dv6647cl and I have the SP52477.exe file. Latest bios for this computer. Is there a program that I can use to get the bin file from the sp52477.exe file? I have a flash programmer. Thank you.

use 7zip to unpack the exe and produce 2 .wph files + flashing utilities etc.
open the 30cff34a.wph file with an HEX editor and delete everything from address 100,000 Hex to the end, save changes and then rename it to a .bin extension. You'll end up with a file with a size of 1,048,576 bytes (00000h-FFFFFh bytes in the editor window). That one you can flash into the chip.
I don't know if there is any difference between the 30cff34a.wph or 30cff34b.wph files, looks like the 30cff34a.wph has more modules inside.
