/writeromfile and /writehdrfile causes a crash dialog to appear in windows 7 and in a windows xp VM.

Try >this< procedure. Maybe it will work better.

You must use this Python 2 script to unpack the HDR from EXE and then CodeRush’s PFSExtractor to unpack the HDR into its components.

thetruthisalie · February 27, 2018, 3:06pm

Is there an compiled version of PFSExtractor?

plutomaniac · February 27, 2018, 4:53pm

Yes, at github Releases tab.

thetruthisalie · February 27, 2018, 8:59pm

Found it here for anyone looking:
https://github.com/LongSoft/PFSExtractor/releases

thetruthisalie · March 3, 2018, 8:15pm

the python script gave me
O7010A25.exe_decompressed.hdr

Which I then fed to PFS which gave me a bunch of files:

What do I do next?

thetruthisalie · March 3, 2018, 8:38pm

UBU was able to open section_0_A.25.data:

Select option for update

So I guess I could just proceed to mod?

How do I flash it when done?

The BIOS region of the SPI chip is “section_0_A.25.data” file. Provided that BootGuard is not enabled on your system (check via MEInfo -verbose) and that the BIOS is not write protected (access error when reading/writing), you can use flashers such as AFU or Flash Programming Tool (fpt -bios -f bios_mod.bin).

how to compile .hdr file of dell?

Aditya11tt · May 23, 2018, 7:49pm

how to use pfsextractor for .hdr file can anyone help?

go2net · May 24, 2018, 4:59pm

Suppose your PFSExtractor.exe and hdr file in same folder at d:\tmp, run cmd, change to folder d:\tmp

then you will see folder create by PFSExtractor , inside this folder have all extracted files

Aditya11tt · May 27, 2018, 4:38pm
