I sent you the full package I extracted in post #23. I used UniExtract "Universal Extractor" it's a free download tool here - https://www.legroom.net/software/uniextract
There is several files in there that maybe you thought was the right ones (There is a ME.bin 1416 and a capsule file too PS-113.cap, neither are the BIOS, BIOS is PS-A113.bin)

Sorry, I don't know about Dell recovery, you'll have to google around for your exact model and find some guides.

@Lost_N_BIOS, would you be able to provide the rom, hex, and bin file for the following?

https://www.dell.com/support/home/us/en/...ctCode=xps-8700

I keep getting a "The command line parameter is not correct" error message. Greatly appreciated!

Thanks!

@Lost_N_BIOS - Thanks for the files! Do you know if it is possible to insert a modified .bin file into the original executable file or it is even possible? Of course, by me asking, i probably shouldn't be attempting it!!! Thanks again!

@legacyuser - possibly, but I don't know how to do that for this particular Dell BIOS, sorry. Doing that would not get around any security checks performed anyway, if the mod BIOS fails security check and wont flash.
You'll have to try -force or -forceit and see if that will help, or find working version for this BIOS of AFUwin/AFUWinGUI (3.03 is stock version) and use /p flag only (If all your edits fall within the BIOS region only, usually that will not be locked down)

You may also be able to use FPT (Flash programming tool), download Intel ME System tools package V9.1 from section C here
Intel Management Engine: Drivers, Firmware & System Tools

Test the following, without changing anything in the BIOS files if output is received (This is to test dumping BIOS region only, then flashing back that exact same BIOS region only without modifying anything)
FPTw -bios -d dump.bin << This dumps BIOS region only
FPTw -bios -f dump.bin << This flashes BIOS region only, using above dumped file.... If OK without error stopping you, then you can do as mentioned below, if error stop and show me image of the error

IF that works, then you can use your modified BIOS file instead of the above dump.bin

Hi guyz can i flash HDR file with USB Programmer CH341A ? or can I just rename HDR to BIN ? and flash ?

#41 RE: How to extract contents of this Dell BIOS package? by plutomaniac 13.11.2018 17:39

No you cannot. HDR includes parts of the total SPI chip image, but not all of them. What do you want to do? Make sure you have the current SPI chip dump backed up first before doing anything else.

Hi no think bios is bricked I wanted wipe administrator password (where it says ''unlock'' in BIOS bottom) by shorting pins on BIOS chip but now I get blank screen

#43 RE: How to extract contents of this Dell BIOS package? by plutomaniac 13.11.2018 18:07

It seems more likely that you burned the SPI chip instead of bricking its firmware. Try to read/dump its contents via the programmer.

I managed to short another DELL laptop but older think 4th gen intel and dat worked .. dis not...
