    Latitude E6530 - Trouble Extracting BIOS Image From EXE

    Hi folks,

    I'm having a hard time extracting this Dell BIOS. I have a Dell Latitude E6530 that has BIOS corruption and I need to reflash with CH341A programmer. I have already taken dumps of both the 4MB and 8MB chips on the motherboard.

    Service tag number for this model is: "JYDWYW1".
    Link to latest BIOS for this Service Tag: https://dl.dell.com/FOLDER05371360M/1/E6530A22.exe

    I have tried:
    • Simply extracting with 7zip
    • PFSExtractor
    • Using "/writeromfile, /writehdrfile, and /writehexfile" commands
    • Check Temp folder


    None of these methods got me the 2 files that I am after.

    I eventually was able to extract out a set of .bin files using a python script that was downloaded as part of the BiosUtilities collection on github. However, none of these 11 .bin files do not match the file size of my original (corrupted) dumps which should be 4MB and 8MB.

    In my desperation, I searched this forum and found someone with a similar problem and used the two BIOS files that was provided as a solution in their threads and flashed those. They did indeed allow the computer to POST, but the model is off and now I can't flash the correct BIOS from MS-DOS USB because the Dell thinks it's a different model than the BIOS .EXE is looking for. I guess I wasn't paying close enough attention and used a similar, but wrong model's BIOS. Ugh. But at least it did demonstrate how flashing a new BIOS fixed the original problem. I just need to flash the correct one.

    I think I just need to get those two files and then wipe both chips again and reflash with the correct files and I will be good to go. I just can't seem to figure out how to get the two files I need and I haven't encountered a Dell BIOS that I wasn't able to get the BIOS images from before, so this is kind of new territory for me.

    Thank you for your help.

      extracted files from update exe. I used Dell-PFS-BIOS-Assembler-master from github. you have to merge both files and replace modules with UEFITool. Using FIT Tool to clean ME it will split files in right sizes.

          Hi. Thanks for the reply. Unfortunately, those files you extracted and zipped for me are the same files I was eventually able to get myself. I have no idea what to do with them to get a 4MB and 8MB file.

          I really appreciate you helping me though. Thank you!

              I told you, merge bios files and replace modules from full bios with extracted modules with UEFITool. Then perform a clean ME to full bios and FIT will split files. I will try to do it if you van't but I am a little bit busy so after 4-5hrs I will be able to help you.

                  Ok thank you. I briefly started reading some guides about how to do that, but I've never had to do this before and right now, it all seems a bit over my head. I really appreciate your help and please, take your time with whatever you're working on now. I'll just watch this thread for your reply.

                  Thank you again.

                      ok, try this and let me know if works. your bios has some errors, I replaced Bios Region with extracted from update and performed a clean ME. New bios has no errors, i hope will works.

                                  ⚠️ Not a Rescue BIOS. Flash at Your Own Risk. ⚠️

                                  This is not A17.

                                  This is not listed on Dell's support site.

                                  This is an unreleased internal firmware revision recovered from a university loaner Latitude E6530... and it possibly bricked the system it came from.

                                  It is from the 8 MB Winbond W25Q64 chip. Could be nothing burger but given the anomalies this is a very interesting firmware dump.

                                  Firmware collectors and reverse engineers might find this useful, It contains certs, modules, and DXE drivers not present in A17. This is likely...

                                  Hi

                                  i have dell latitude E7270 with following symptoms:
                                  - takes long time to restart.
                                  - sometimes powers on and then off
                                  - sometimes while working it just dies,

                                  From googling online bios clean could possible resolve this?

                                  i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)

                                  As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.

                                  Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                                  so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                                  in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...
