I got a Dell Latitude 3330 with current BIOS version A01.

I want to update BIOS version to A13. I have downloaded latest BIOS EXE file from Dell website. EXE file runs fine, restarts the computer but on startup no BIOS flashing starts. The OS is starting fine with no error messages and that's it.

I have tried Windows as well as DOS boot up. Also disabled Intel Virtualization But, nothing works out.

Any idea why cant i update my BIOS?

So decided to flash BIOS using CH341A programmer however i dont have 8+4 BIN files for the same. It is legacy BIOS and not UEFI.

Make a backup of your current bios before flashing anything!!

Don't flash the Dell bios with a programmer, this will delete your machine specific information like serial, MAC address...

Otherwise try using an earlier version and / or try using a DOS boot stick

Thank you for your advice.

I have backup existing BIOS however it seems to be corrupted as it is not letting me upgrade even after using Step By Step Dell suggested methods.

I have already tried upgrading using Dell DOS Bootup method as well as rufus.ie and using all USB port. But system just boots to windows after autoboot during BIOS upgrade process. Same story with earlier versions.

Post link to backup or attach it here.

Sure.

Here is my existing Dump 8MB and 4 MB file. It is working and version is A01

I am looking for upgrading to A13. Exe file is available at https://dl.dell.com/FOLDER05122121M/1/3330A13.exe. But i dont have 8 and 4 MB BIN files for this.

Thanks,

Well, in a way no one has 8 and 4 MB files.

If you unpack the update packages, you get a list of files, which are partly included in the stock bios region, or represent other firmware regions or may be firmware for another chip (EC firmware):



Unfortunately already update A02 contains an update of the EC firmware, which seems to be on a separate chip. Other than that there's an ME update, and that's an unconfigured update file, nothing that can be build directly into a firmware.

I suggest you try to update to version A02

If this doesn't work, try to update Intel ME separately to check if it's this part of the update which may stop the update process:
- Download Intel ME System Tools v8 r3 - (2017-11-19) here (section C2):
Intel (Converged Security) Management Engine: Drivers, Firmware and Tools

Unpack it, go to the folder FWUpdate, choose the folder corresponding to OS:



Unpack the attached ME firmware into the selected folder, open a command prompt there as administrator and run

FWUpdLcl64 -allowsv -f ME_A02.bin or in dos/win32 FWUpdLcl -allowsv -f ME_A02.bin

Please take a screenshot of the command prompt window and post it.

First up all, i want to thank you for taking out your time and post revert. Means a lot.

As i first step, i have tried updating to A02 using both Windows 10 as well as DOS bootup. It is not getting updated. After Auto Boot, system boots to windows without updating BIOS. As usual , no errors of any sort.

I will proceed with step 2 by downloading

Did you try to run the update on a command prompt as administrator? There are options that could make it writing a log file, for example 3330_A02.exe /s /l="c:\temp\dell.log"

I will do it right away and post results in next few mins

Thanks.

Then run on the DOS command prompt (booted from an usb stick):

......\MEInfo\Dos\meinfo -verbose > meinfo.txt

and post meinfo.txt

Well, at least something that's definitively not OK and will keep the update from running. But it might of course not be the only thing...

Left side is yours, right side is what it should look alike:



Flash the attached file in the 8MB chip, it contains a cleaned = freshly configured 'clean' ME according to this guide:
[Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization

The 4MB chips is still untouched, it contains part of (unchanged) bios region, no need to flash it.
