For Dell XPS 8930 bios here is only bios region BIN file dumped via FPT above 8MB total size
http://s000.tinyupload.com/index.php?fil...878666187033407
and here is full dumped bios BIN file above 16MB total
http://s000.tinyupload.com/index.php?fil...882528862290188

Interesting this is, when I flashing moded BIN file to the Bios region only(not ME gbe etc section becuase those sections are protected can't be flashed using FPT)It successfully flashing!! and also all changes done in moded bios image file successfully get flashed to bios region, BUT AFTER PC REBBOT, all changes made in bios just restoring back to its original default settings. Interesting!! I never saw that kind of behavior after successfully flashed the moded image.

for R00 extracted file from stock bios exe file using AMIUCP. 1.07 , it's total size around above 12MB, neither above 8MB no above 16 MB. but that 12MB R00 file is opening via AMIBCP BUT just setup section not showing in AMIBCP, so that extracted file from stock bios exe is total useless or we need newer version AMIUCP where it can properly extract R00 file from stock bios exe file.This AMIUCP. 1.07 is 2011 version tool which is too old.

@earthoo7 - Two PM's about this and you erased the post??! Do you still need help with that, or did you sort it out?

@superb123 - What did you dump the 16MB file with?
And yes, this is normal, sometimes if there is no BIOS/SMI/SMM lock on BIOS region, or system has FD/ME/Service etc jumper, you can dump BIOS region with FPT, edit, and flash it back.
What do you mean "restore" back to original? Sounds like a failed BIOS edit, so no changes visible.
OR, do you mean you see some kind of BIOS auto recovery? If yes, in that case, it could be failed edit and it soft-bricked so auto-recovery kicked in, or no edits are possible so that would always happen (Never seen with Dell, only HP)

Looking at another 8930 thread where I tried to help user - [REQUEST] Unlock options and Remove Dell SupportAssist detection from Dell XPS 8930 bios
We found Boot Guard was enabled, so any edit of the main BIOS region where you'd do menu edits cannot be done or = brick.
Please check with MEINFO and see if boot guard is enabled on your system, see end of the report from this command >> MEINFOWIN.exe -verbose
If you see Measured or Verified Boot enabled at left/FPF side, you cannot do menu mod or use AMIBCP etc. But, if needed, you can still change any setting, hidden or visible, via NVRAM edit
What is your goal here?

Yes, as mentioned many times over in this thread, the extracted files from EXE cannot be used directly to recover/rebuild a BIOS usually, at least not as they are or whole etc (you have to know what you are doing, extract and use only certain portions etc)
AMIUCP properly extracts this file It's just not something you can edit in AMIBCP as it is, can only be used to rebuild BIOS when you know what to do.
If you want to edit BIOS, you edit your FPT or programmer dump. But, do keep in mind what I said above, boot guard is probably enabled on your system too, so anything you edit in a yellow/cyan/red region will = brick (open file with UEFITool 51-57 NE Alpha to see these Boot Guard covered colored areas I mention)
This means you CANNOT edit this BIOS with AMIBCP, at all, anything you want to do in there is covered by Boot Guard and will = brick.

If you need to change some settings, give me a list of exact setting by name you want changed, and what you want it changed to, and I will do NVRAM edit on your FPT BIOS region dump above.

After bricking my Inspiron 7567 after an unsuccesful attempt of BIOS update I need .ROM and .HDR files from .EXE file below. Can anyone help me with this?

dl.dell.com/FOLDER06139157M/1/Inspiron_14_15_7000_Gaming_1.11.0.exe

None of the Recovery Modes are working for me so my only hope is to reach to ROM and HDR files so that I can force flash BIOS via using "End" button.

Any help or guidance would be greatly appreciated. Thanks in advance.

@Lost_N_BIOS
it is bios of dell if i extract it i found 2 bios region, 2 me rgion.
both me region are same & both bios region are different.
i need to change my bios region so i tried but here is somthing different are as following..
only bios region size same if i directly replace it with uefitool it will show no display bcoz if you drag its
bios region in uefi tool you find 2 paading file extra.
so i replace one by one from new bios region to oldbios region & flashed it but will not worked.
so i decide to change with other bios region (as i mention above got 2 bios region from .exe) but it did not worked means no display.
note-my backup bios is working only need to change its bios region.
if i replace only large file of new bios region it did not worked.i download .exe with sevice tag so .exe is ok.
i also tried all above mention method with fitctool with me region which i got from .exe but it also not worked.
if i use new me rgion only with my old bios it worked okay so no problem on me region side.
what should i do next..
i am uploading .exe which need to extract & second which need to replace bios region with working backup.
please replace new bios with backup bios in right direction & make bios.
i will flash it & report it status.

thankyou

@earthoo7
Use Dell PFS BIOS Extractor

@DeathBringer
first download files which i upload then extract only 1.exe which are not extracted with dellpfs extractor
in second folder files issue as i mention in my post

@superb123 - What exact setting do you want changed, and what do you want them changed to? I assume the two settings you showed in AMIBCP image, correct? What do you want them changed to.
Yes, Boot Guard is enabled here, so you cannot do menu edit or flash in any changes made by AMIBCP. You cannot disable boot Guard, without replacing the PCH with new clean one without key burned into fuse
So only NVRAM change of live/current settings can be done, via grub/setup_var, RU method, or by directly dumping and flashing NVRAM ONLY with FPT
Please dump NVRAM for me via next two commands, and send me this. This we can edit/flash without violating Boot Guard or BIOS lock etc

FPTw.exe -a 0x802000 -l 0x20000 -d NV1.bin
FPTw.exe -a 0x822000 -l 0x20000 -d NV2.bin

@earthoo7 - Link me to the Dell BIOS download page for this model, then I will check. But yes, as mentioned above you extract with PFS Extractor, if other methods do not work
Sounds like you already can extract, so all you need to do is find which BIOS applies to your exact system by comparing FPT or other dump directly from the board.
You cannot usually directly swap anything as a region only swap, from the exe, you need to extract volumes manually and replace them one by one in hex editor (not all volumes in the exe extracted BIOS will go into target BIOS)
If you are needing to fix laptop, link me to the Dell BIOS download page, and give me a link to download your programmer dumped BIOS from board only (no other files, I am on limited internet and this is all I need)

@Lost_N_BIOS
i replace its each section with uefitool after analyze its hxd value & size as much i can.
but not worked
here is its .exe

https://www.dell.com/support/home/en-in/...F3UT090/drivers

backup file here
https://drive.google.com/file/d/1JEdpf_H...iew?usp=sharing

@earthoo7 - You linked Dell Studio 1458 above in first link, and then under that Optiplex 3050??? What model are you working on here?

@lost_n_bios
need first only how to extract its .exe.
in dell 3050 need to replace bios region

@earthoo7 - For 1458, sorry I don't know, can't get this to run properly and no methods I know to extract work. Run this on the 1458 system and then once winflash is running you should find BIOS files in %TEMP%
For 3050, I will fix for you tonight, I ran out of time to do right now, sorry.

@Lost_N_BIOS
agree...
