Dell E6430 Bios Wil not update.

Hi JRBurns80,

Thanks for posting.

Apologies that you are having difficulty updating the BIOS on your Latitude E6420.  Be sure that after you reinstalled the Operating System that you installed the drivers in the correct order.  Here is a Dell Knowledge Base article you may find helpful.  Also other users have posted that you should perform the BIOS updates in the Operating System the computer came with rather than Windows 10.

If the drivers and download page OS drop down list is set at W10  surely all the BIOS updates and drivers shown should be W10 compatible. Re-installing the old OS, with all the time and inconvenience that entails, every time a BIOS update is required is ludicrous.

I'm not sure why @robert p is wasting time talking about the OS.  The BIOS update application when launched from Windows simply sends an image to the firmware and then the system itself handles the flash on a reboot, so OS support isn't relevant here.  And after all, as the OP said, the BIOS can also be flashed via bootable flash drive, and even THAT has apparently failed, which is further evidence that the OS isn't the problem.

At what point exactly is this failure occurring?  Are you seeing an error when you try to launch the updater within Windows, or does that part work and then you see a failure message when the system attempts to apply the BIOS update upon reboot?  And either way, do you get an actual error message or anything more detailed than just "Failed"?

That's the odd thing, there is never an actual "Failure" notice, no erros written to the BIOS log or anything, it's just not updating. The installer runs fun, reboots the laptop, and then nothing happens.  I read another forum stating something about this BIOS can be stopped from being updated by some locking mechanism but I've never dealt with that.  There is no BIOS pw or any admin pw for the bios setup either.  I've tried flashing from the windows installer and from the DOS installer, neither worked.  the program processes but nothing happens, no failure, no error, nothing, Just that the bios never updates. As stated I tried flashing the same bios that it already has to maybe "unstick" it but that doesn't work either.

Was this computer shipped from the factory with Windows 10 installed?

No, it had windows 7 on it, but the OS would not cause the BIOS update to fail, the flash of the bios is a prior to OS loading.

I am having exactly the same problem with the same model computer.  I most recently tried doing it from a formatted USB drive.  No error messages or anything.  The computer reboots.  Was there ever a solution found?  Thanks.

HI I have the same problem, I keep getting urgent update from the Dell Command update app , I download it to the desk top , I run it in Windows and it shows a progress bar , it then reboots and is exactly the same Bios as before I have done this at least 10 times to no avail.

The Laptop was shipped with Windows 7 on it but was updated to windows 10 when the OS  first came out, surely we do not have to downgrade back to Win 7 to update the Bios.

Any help would be appreciated

But Dell Command update app is not supported by Windows 10. Try  Dell Support Assistant instead.

I have the exact same problem with my E6230. Dell needs to do something about it, or next time many of us will pick a brand with better customer care. 

Dell Update seems to work better than other Dell utilities for updating all Dell Drivers including UEFI BIOS Updates on Windows 10 however once installed, in order for it to work it has to right clicked and ran as an administrator:

https://www.dell.com/support/home/uk/en/ukdhs1/drivers/driversdetails?driverId=HGDR1&osCode=WT64A&productCode=xps-13-9365-2-in-1-laptop

See here for details:

http://dellwindowsreinstallationguide.com/dell-update-for-windows-10/

N.B. although it only lists Inspirons, XPS and Alienwares as compatible. I've had it working on some OptiPlex models.

Otherwise try manually updating the UEFI BIOS using the A25 update here:
