Hello guys,
I stupidly tried to read out my BIOS & EC flash (with a clamp). This didn't work, I only read FF's. But after this operation, the PC is not longer turning on, just beeps 5 times (and blinks red) then 2 times (blinks white). The manual says this is the error code for: "The embedded controller cannot find valid firmware.".
I think it locked itself because of my experiment. Is this fixable? I now removed both chips from the board and dumped them, I attach the files in this post hoping someone can help me fix my stupid error. Thanks so much in advance anyone...

Embedded Controller issues, living an absolute H*LL with my ASUS Vivobook Pro 16X OLED
I've been dealing with so many complications for months, trying to find and then fix the root cause of the issue I really need help and I have to solve this on my own (Going to Asus headquarters isn't an option for me. First, because I'm very stubborn and want to insist that I can fix this sort-of-myself somehow, and second, the location is too far away for me anyway).
Right now I'm desperate trying to put an end to this nightmare, but OK, I'll do my best to be somewhat brief in explaining and relating the entire situation and context.

Hello everyone,
I need some help regarding an EC firmware (Embedded Controller).
Model details:
MSI Vector GP66 12UHSO
Motherboard: MS-15441 ver 1.0 "ENE KB9548QF2"
After fixing a power supply issue on this board, it turned out that the EC chip was also damaged.
I’ve replaced it successfully, but when I try to program it, I can’t find any EC firmware available.
I’ve already tried:
Extracting the EC firmware from the official MSI BIOS (downloaded from the MSI website),
And also from the original BIOS dump of the... -
ITE IT8390 (IT8390E-256) programmer "ITE Download Board 4" user manual + firmware, flashing ITE ECs on the cheap
Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...
