No, your device only matches one of those two files.

DELL OptiPlex 7450 All-In-One, need bios, clean ME
Hello everyone,
I've got a problem with my Dell AIO 7450. I'm stuck on a screen with error message: (A7) Me FW Downgrade Request MeSpiLock Failed. After a few seconds computer reboots again. I can only enter bios or boot menu. I can't even boot from USB, nothing.
I've tried all methods from Dell site, flashing bios through recovery (CTRL + ESC method) with many bioses versions but nothing helped.
I searched for ways to solve this problem and found a similar problem on the forum, which was solved by creating a bios with clean ME.
So I wanted to try to prepare such a bios by myself (with ME Firmware Cleaning Guide) but I can't get the bin from Dell exe bios. I've tried all the methods (python scripts, Dell_PFS_Extract, Dell_hdr, Dell_Image_Extract v2) and they only works on older dell bioses.
So, I am begging for help, please prepare a bios with me cleaned.
The original bios is in the attachment.
I can only flash bios with CTRL+ESC method with rcv file (I think it's an exe bios file but with different extension).
RegardsComment

Re: OptiPlex 7450 All In One bios
Thx SMDFlea,
PFS Extract 4.9 did the job, but there are many bin files in the unpacked folder, and this structure looks like the files that result from drag&drop a single bin file into the FIT. How can I load all these files into FIT so that I can build a new BIOS/EXE file after replacing the ME?Attached FilesComment

Re: OptiPlex 7450 All In One bios
You might be able to bypass the ME error message by using the MECLR1 jumper,if the motherboard has one https://www.dell.com/community/Inspi...50/m-p/8323222 .If you can do that and boot into windows you can run the bios update exe (not the rcv,it doesn`t flash the ME firmware) .If you can`t do that then your only option is to buy an SPI programmer to make a backup for repairing or take it to a repair shop.

Re: OptiPlex 7450 All In One bios
Ok, but when I'm flashing through recovery flash mode (CTRL+ESC), on the last stage I get error: ME Firmware Update Failed. All previous stages are ok. Beacuse of that, I was wondering if there is any way to rebuild this RCV file.Attached FilesComment

Hi folks,
I got a Dell Optiplex 7010 micro PC (Exact Model) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: https://www.badcaps.net/forum/troubl...ssword-patcher
After flashing the patched the BIOS, the PC is unresponsive with a solid AMBER power LED (not documented in manual anywhere)
Steps I took:- Read BIOS with CH341a, verified hash twice

Dell Optiplex 3070
Hi,
As explained in my introduction, after many years I finally bricked one computer updating the bios (power shortage).
Brand : Dell
Model : Optiplex 3070 Micro
Motherboard : 02N3WF
Service Tag : ****
Chip BIOS model : MX25L25673GMI-08G
I'm new at flashing bios directly so I bought a cheap CH341 dongle.
I tried it on an old computer and I successfully read the bios from a MX25L128Z3F chip with the SOP8 Clip.
The I tried to read the Optiplex 3070 chip BIOS to make a backup.... -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
