    And what?
    The script was in your case does not apply, and exit normally without errors like before.
    Try different methods.

    anyone help? bricked e6410

    i also have a bricked latitude e6410. i can extract the bios from dell.com.au using this tool. But what to rename the file to?
    Ive looked at sing WinHEx as per another suggestion but there is no name there. just PFS.HDR

    I think i know the recovery procedure.. plug in usb stick with HDR file, hold end, plug in power
    I have the compressed HDR file..
    or do i need to throw it in the bin..what a waste...
    Surely someone can paste a HDR file that works.. it doesnt matter if its an early bios version, i can upgrade once i get the laptop booting again....

    :(

    just an update, i managed to extract a rom from phoenix tool and i see text saying rothschild0.rom in winhex.., with rothschild being the codename for the 6410.. but using this name still didnt work. I would love to know if anyone has managed to successfully recover a bricked 6410, or any of the newer dell bios's

    Very simple method. (dell ami uefi bios)
    1. run the bios.exe
    2. when starts the winflash go to c:\ProgramData\WINFLASH\
    3. copy the bios.bin to an other place
    4. close the winflash

    Thanks to everyone on this thread for their contributions, especially JimboBobB for the script and telanx for the use instructions.

    I've managed to extract the .hdr file using Python. I'm stuck what to rename the .hdr file to allow it to work using the [Press End Key and Plug In Power] method. It looks as though others have gotten stuck at this point also.

    As others noted, the extracted .hdr file shows an internal name of "rothschild0.hdr". However, when the .hdr file is renamed to that, it does not work to flash to bios. What is the correct file name? Or is there another issue?

    Has anyone solved this problem and gotten it to work? I'm working on a Dell E6410 with a BIOS password that I'm trying to navigate around by downgrading the BIOS first.

    Thanks to all.

    Can anybody help me with Dell E5420 and E5430 ?
    I have now extracted the HDR file and dont now how to name it.
    Can i just open the HDR file with WinHEX or should i decode it to ROM or BIN and den decrypt it to get a name?
    Without decrypting, when i use WinHEX on HDR file i can only se HDR in one place and there is only PFS.HDR, is that the name?
    Becouse when i try that, nothing happens.

    I have tryed to remove harddisk, batteri and power cable.
    Put USB memory 128MB FAT with HDR file in USB port.
    Press END and connect power cable.

    But computer wont turn it self on, i have to press ON to start the computer and then it just starts normally.

    What am i missing? Maybe its not END button? Name of hdr maybe isnt PFS.HDR ?

    Please help

    Does the tool work with extraction or Dell (ami aptio) UEFI

    Machine: Dell 15 3520
    BIOS Dell (AMI APTIO)
    Issue: extraction of *.hdr
    OS: Centos7

    Have not been able to successfully extract the hdr file or determine the proper name of the hdr file using any of the following

    phoenixtool2.59 ( I get correct rom file name)

    uefi_firmware_parser ( exit with : None )

    dell.py ( I present you with ... ) I get the below:
    Traceback (most recent call last):
    File "./dell.py", line 33, in <module>
    (start_match, end_match) = match.span()
    AttributeError: 'NoneType' object has no attribute 'span'

    Please, any input
