Trying to flash HDR files into newer Dell's

[Mirage2000]

And the file have virus... It's a trojan !

Hey guyz I have dell bios extracted to HDR then HDR extracted to bunch of files which is BIOS ? there are 3 5MB files ...
Can I flash HDR file with USB Programmer CH341A ? or can I just rename HDR to BIN ?

No, no, and no The closest one from the extracted HDR is payload.data, but I don't think it's complete either. Are you sure the exe did not contain a .rom, if you are not 100% please link the BIOS.

Usually that rom (or payload.data) + HDR are used for recovery, often by pressing the END key with system unplugged, leaving END Key held down and plug it in leaving the ket held for 3-5 seconds to see if recovery starts. This is system specific possibly though, and you have to have the files on USB and they need to be named whatever recovery files should be for your specific model (Unsure how to find that out, maybe if you link me to the BIOS itself)

Another similar method for recovery in last post here

For HDR only, you can use DCCU (Dell client configuration utility - CCTK) if older to make an EXE installer, or Dell command | configure, or OpenManage client instrumentation (OMCI)

If it's programmer only you are after, do you have a verified and valid (Not all FF or 00's) backup? If yes, you have this, compare payload.data in UEFITool, copy from payload.data to you backup, all matching regions, then save. Then open your backup in UEFITool again and extract the main visible padding sections, search those for your Asset and service tag, and LAN MAC ID, then copy those into exact same padding on your previously created BIOS, then test that programmed back to the system.

Dell is a PAIN, especially without .rom. You may need to find a confirmed working dump for your model, then copy over the system specifics I mentioned and use that instead.

Oh yeah I extracted HDR file and there are more files and 3  5MB files ... so what should I do ?
yes there is playload
1.section_5_10.0.60.3000.data
2.section_0_A.20.data
3.section_0_A.20.payload

4 the forth is 1.5MB section_6_10.0.55.3000.data

1.5MB is usually Intel ME. Please link me to this BIOS, stock version, so I can see if there is .rom or not.

With or without docking socket on bottom? E5250 or 5250 without E in model name?

Sorry, I am not sure about what the "Docking" thing is, I assumed you would know if you had or not. I asked because the page you linked shows both type of BIOS, I mean for both systems there is BIOS download.

Yes, often there is two BIOS chip, one is BIOS and one ME/other data. I checked E5250 (W/ Dock)

There is no ROM in file, only HDR as you extracted. Only option is to order chips like you did, or in google find working dump for this exact model, such as this, which you can correct your service tag/asset tag, LAN Mac etc later or before if you have programmer

For above to download, you must use elite Brazilian proxy. I can download for you if you need, these are probably full 12MB dump, you would need to split and then program using programmer

I see there is 1.5MB or 5MB ME too (Vpro or non-vpro), be sure you choose correct one when you order BIOS Chips, or you may need to get a programmer later if you cannot update ME or unlock FD to force update ME to other version etc. If your board has service, FD, FDO, ME etc jumper then it will be easier.
