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

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).
Regards

PFS Extract 4.9 -> https://www.badcaps.net/forum/showpo...95&postcount=6
.

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?

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.

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.
