#1 | Dell Latitude E6420 - Need help with BIOS flashing datum

Fri Jan 03, 2020 6:46 pm

Hi everyone!

First post in this forum. After reading a few posts I thing it is the best place for me to ask for help.

Here is my story.

I have a laptop, a Dell Latitude E6420 (with nVidia Card).
I decided to upgrade the BIOS from A16 to A25 since it was supposed to fix a seurity thing with Intel Processor.

Bad idea! I forgot the old moto : If it ain't broke, don't fix it.

The computer works. I can boot it, works in Windows, etc.

But...

Whenever it receives a "reboot" command, it power-off.
Reboot from Windows? Power-Off
CTRL+ALT+DELETE from DOS? Power-Off
CTRL+ALT+DELETE from the BIOS or Boot Selection Menu? Power-Off
Sleep command from Windows? Power-Off

Shutdown and hibernate works though.

So I decided to roll-back to A24 (or the first version that will fix the problem)

But... it can't!

When running the bios file (either form Windows, WinPE or DOS) it dost some "preparation" and try to reboot. The power-off.
The flashing process never start and I am stuck with A25.

What I wan to know if is there is any program that can flash the bios "live" without having to reboot?
Like the old way "toolname.exe -flash biosfile.rom".

If yes, which one? And where to find it?

Also, I suppose I cannot flash the EXE file itself and that I must fid a way to unpack it?
I heard about HDR file and a Python script in the MDL Forum to extract the HDR file and an unpacker for it after but I am not sure what I need and what I need to do, in which order.

Anyone here can help me?

Thanks a lot in advance for your time!

@anarethos - Sounds like ME FW is messed up, can you see ME FW version listed w/ HWINFO64
On the large window on left side, expand motherboard and find ME area, inside that get the ME Firmware version. Or, do you see no ME FW area, or 0.0.0.0 or N/A for the version

You may need to order a flash programmer (such as CH341A) + SOIC8 test clip with cable to fix this.
Good news is they are cheap (less than $7 total shipped for both parts), bad news is it's a long wait 3-5 weeks if you order cheap, but you can pay more and get faster if you are in a hurry and don't care about prices.
Let me know if you need linked examples to these on ebay.

Also, lets see what you can do with FPT for now too

Check BIOS main page and see if ME FW version is shown, if not then download HWINFO64
Then on the large window on left side, expand motherboard and find ME area, inside that get the ME Firmware version.
Once you have that, go to this thread and in the section "C.2" download the matching ME System Tools Package
(ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc) >> A16 and A25 both contain V7 ME FW, so get the V7 tools package
Intel Management Engine: Drivers, Firmware & System Tools

Once downloaded, inside you will find Flash Programming Tool folder, and inside that a Windows or Win/Win32 folder.
Select that Win folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the following command and send me the created file to modify >> FPTw.exe -bios -d biosreg.bin

Right after you do that, try to write back the BIOS Region dump and see if you get any error >> FPTw.exe -bios -f biosreg.bin
If you do get error, show me image of the command entered and the error given
^^ This is important step, don't forget ^^

If you are stuck on Win10 and cannot easily get command prompt, and method I mentioned above does not work for you, here is some links that should help
Or, copy all contents from the Flash Programming Tool \ DOS folder to the root of a USB Bootable disk and do the dump from DOS (FPT.exe -bios -d biosreg.bin)
https://www.windowscentral.com/how-add-c...creators-update
https://www.windowscentral.com/add-open-...menu-windows-10
https://www.laptopmag.com/articles/open-...ator-privileges

Or here is simply registry edit that adds "Open command window here as Administrator" to the right click menu
Double-click to install, reboot after install may be required

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM
I view the forum like this, please bump your thread 1x every 24-48 hours if no reply

@anarethos - You never answered my first question, but I guess I do see the ME FW version info in the meinfo output = 7.1.91.3272 (So you should be using V7 system tools, not V8)
Sorry, I am not great at diagnosing ME FW issues, I only know how to fix/reflash etc, so the meinfo output doesn't help me much. Please answer my first question above, how I asked you to look

Back to FPT, we can sometimes get around error 280, but only for the BIOS region but that is your goal here.
Please redo the FPT stuff, properly, exactly how I posted it (but for DOS), do not use file locations in the command lines, files will be on your USB device.
Enter commands only exactly as I posted, then send me the dump and I will see about which ways you can possibly try to get around 280 and how easily I can make you a BIOS from A16 to use

1. FPT.exe -bios -d biosreg.bin << Send me this file
Test #2 (expected error 280, but redo as typed, just to confirm) >> FPT.exe -bios -f biosreg.bin

Please edit your posts if you need to add more info and no one has replied yet, thanks
Also, still waiting on you to confirm ME FW version the way I originally asked you to check (This is all that matters to me)

Thanks. Please see my edit above at #9 (I'm not asking you the ME FW version, I can see that in the MEInfo reports, as I noted above in my first reply tonight)
And you're welcome! Hopefully I can help you fix this.

MEFINFO report looks OK, based on comparing to a MEFINO report checked by our ME FW guru and forum owner here
Latitude E6420. ME SpiLock failed after CPU change. (3)

But, that does not always mean it's 100% OK, flash programmer or pinmod to unlock FD and reflash ME FW may still be required.
But, hopefully I can get you back to A16 BIOS version (ME FW rollback is not possible, at least not easily, you need unlocked FD via programmer or pinmod)

Here are the available sections under "Motherboard- Intel ME"

- ME Host Status
- Intel Manageability Engine Feature
- ME Firmware Capabilities
- ME Firmware Feature State
- ME Firmware Platform Type

No other sections.

BTW, this laptop was shipped without the vPro feature. I don't have the Intel Management option in the boot menu.

Show me image just like this from HWINFO64, I only wanted to see if ME area is there, and if ME version is shown correctly or not. I assume it will be now, since your MEINFo report looks "OK" as far as we can see

Also, see my edit above ^^ Per your Edit, later, once fixed, if you want, we can enable VPRO via ME FW edit (But you need unlocked FD via Programmer or pinmod)

As mentioned, I already know your ME FW version, and wasn't asking for you to tell me it either (only to confirm you could see ME area in HWINFO, and if yes, if you could see proper version listed or only 0.0.0.0 or N/A (corrupted ME FW))
All of which, we already know is not the case at face value now (ME FW may still be messed up though, based on your original issues mentioned). Once we get you back to BIOS A16, then we know if it's a ME FW issue solely or not.
Please wait, let me check this BIOS and get you info on how to try and disable the lock causing error 280

I must be really tired because I didn't understood (obviously) what you wanted exactly.

Sorry for that !

BTW, what is this PIN Mod you are talking about? I suppose a programmer is a better tool? Compatible with many systems?

I have found the lock causing error 280, but in this BIOS, only way to remove it is via directly BIOS module edit (ie we'd have to flash/program in an edited BIOS with lock edit bypassed, which is not possible while enabled, unless you have flash programmer)
Please also make this FPT dump and send me the file >> FPT.exe -desc -d FD.BIN

I think I can help you relfash via AFU Flash, but it's not ideal to flash that way, but it will retain your system info in place.
It would be best if you order a flash programmer, dump both chips, send to me so I can edit back in original ME FW and original A16 BIOS region etc, then you program back

* Edit - Didn't see your post above. It's OK, I thought maybe you kept missing what I was asking

Sorry, I thought I linked you to the pinmod info, see section E.1 here - [Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing
Do not do anything for this yet, even if you want to, until I see your fd.bin dump above (it may not be any help with BIOS region flash anyway, it would only help us to reflash the ME region easier, BIOS region is not usually locked in FD)

Yes, programmer is best way, it's cheap and compatible with many systems (will save you in the future too) Less than $7 shipped for both items you need, if ordered with 3-5 week wait, can be purchased for more $$ at various places if you want to pay more for quicker delivery
Here is examples of the two items you need
