Dell E6430 Dump of A18 Bios
Hello,
I need a dump of the recent A18 Bios of Dell E6430 (Bios and EC)
The Notebook has A12 and just ingores any attempt to update its bios. (the upgrade itself does never start, it just does a reboot)
I guess it is because of "Signed Firmware Update Feature", as I programmed the Eeproms with an eeprom reader. I have trouble with lan connection when using a docking station.
There are dumps already posted on badcaps, but just A07 and A12.
Or is there a way to create the 2 bin files out of the 14MB .hdr file you can create?
Thanks for your help!

Re: Dell E6430 Dump of A18 Bios
i did not find a way to extract bin form hdr yet
but as i remember if you have hdr file, put it on fat32 formatted usb drive and turn off laptop
hold END and turn on while holding END and it should force flash from stick
as i remeber good...
Code:http://en.community.dell.com/support-forums/laptop/f/3518/t/19534608
E6430A18.exe /Writeromfile
or
E6430A18.exe /Writehexfile
i dont have dell machine so when i run flash file it just crashes so i cant do anything :/Last edited by ala_borbe; 07-19-2016, 06:30 AM.Im Back... sort of...

Re: Dell E6430 Dump of A18 Bios
Flashing the HDR File while pressing "end" does not work. Either because it is not the proper HDR file, the filename is wrong, or because the signed firmware feature prevents this. Maybe this method does not work anymore anyway.
The /writeromfile /writehdrfile does not work anymore since quite a while.
Is it possible to dump the two Eeproms (8MB+4MB) from windows/linux using software? RWEverything or something like this?

Re: Dell E6430 Dump of A18 Bios
I managed to Dump the Bios from Windows using Intels FTPW Programm (it creates one 12.6MB file, but this can be split).
Is there anyone with a Dell E6430 with recent Bios A18 who can help me?
I attached the FTPW Progamm, just unzip and execute dump.bat (I guess from command line, I did not try it from Windows Explorer, but it may work also) and upload the the file bios.bin it creates?Attached Files

Re: Dell E6430 Dump of A18 Bios
It does not work. It just does a normal reboot, when it is supposed to flash.
It does not help to add /f or /forceit suffix. Restoring Bios settings to default does not help either. It does not matter if I try to flash from Dos or Windows.
It does not work with Upgrade from A14 to A15, or directly A18.
