Does this it have a model number ? .Does it start if you flash the old bios back

After the patcher, it stopped starting at all, I tried the saved lamps, it doesn't work...

Я одразу прочитав дамп BIOS, а EC — лише після того, як перепробував many options BIOS з форумів. I immediately read the BIOS dump, and the EC only after trying many BIOS options from the forums.

Test this patched file.

Thanks for sharing.
I tried the file you shared,
I wrote it and verified it was written correctly.

It has the same problem as above: it beeps 5 times twice, the fans spin for a few seconds, and then shuts down. No signal.

rewriting my original, it goes back to how it was before with the password.

Your model can be unlock if you provide 2kb file EEPROM container from MEC1663
No main BIOS patch available for your model

ok, thanks

Hello friends! I used autopatcher, rewrote the patched file in the bios, but as a result, when I press the power button, it blinks 3 times. Then nothing happens. Can someone help?

This has bricked my T470s, great. Now the power button and keyboard flicker and it won't come on fully at all.

Flashing both chips back to their original states doesn't even fix it, it no longer boots at all after trying the PXE driver injector method...

It's a 2017 T470s

I think the original serial number stickers were replaced, all I can find is:
Type 20HG-S14D00 and S/N PC-OPTLL4 17/09

OK, that's good. (PC0PTLL4 with "zero" after letter C.
The 25Q80 chip is your PD controller SPI so must be untouched and write it back as is.
Write the content from the attachment and tell me if it works or not.
It's tested by me on several T470s laptops.

I flashed it just now, it still does the same thing. The keyboard and power button light up briefly then it shuts off. This happens once when power is plugged in, then it is unresponsive until unplugged and plugged back in once more.
