FPTw doesn't flash ... failed to disable flash protection of the descriptor, is it possible to bypass protection by setting correct variables?

@klaxklax3 - Yes, if you are not careful, you can short out anything (host board, board you are trying to fix, CH341A itself) Always have to make sure things are connected properly, which I know is not always possible and shorts happen, it's the life we choose and it can happen to the best of us.
It shouldn't require a new laptop though, but if that is your only option I suppose that's what you have to do.

Show me an image of the FPT error, including what command you typed too. Yes, sometimes it's possible to get around certain errors, using some tricks, other times you will have to pinmod or use a programmer.
Since you have a programmer, there is no need for FPT usage if you are stuck, dump the BIOS, modify it and send me a copy of your dump and your mod so I can check it's OK as far as I can see, and I can also remove all these locks for you too.

I will never ever use a programmer again on a laptop if a chip soldered on the MB.
Even if everything done correctly Intel BG will not let to replace firmware, even if you upload the original firmware with a programmer, PC will not start due to UEFI enforcement policy verification fail. After this there is only 1 option : to replace a chipset.

Pinmod is also not acceptable cuz it is hard to allocate audio chip itself without disassembling.

Don't be scared, people use them all day long, just be careful and use properly and you will be fine. If you refuse to use that, and can't do pinmod (Which is more risky), then you may have zero options and can only use stock BIOS as it is.

Thanks for image, two things here, first you are trying to flash the entire BIOS, which is not needed (use FPT -bios -f filename.bin) and you need to unlock BIOS lock first via grub using setup_var or via SCEWin if possible (I will send you later, if setup_var fails)
I made a guide for unlocking error 368, you can start at step #6 since I will give you variable you need below - [GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash

Rename .efi file to >> Shell.efi
If you cannot see "Launch EFI Shell from filesystem device" on your BIOS exit page, then you must setup your USB stick how I suggest here, and be sure to look at the image so you get it all same
[Help needed] Hidden Advanced menu Bios HP Z1 J52_0274.BIN (2)

BIOS Lock variable to change >> 0x962

So at grub prompt you type the following >> setup_var 0x962 0x0

Additionally, you may be able to flash BIOS from windows, without doing the above, but you will have to test this and see if your BIOS has the bug.
In windows, put system to sleep (S3) not hibernate. Wait one minute, wake system up and try FPT flash again >> FPTw.exe -bios -f filename.bin

1 minute to success...

BTW I ve been checking my DUMP via ME Analizer and it showed up some info, ME FW exists on my model but it is hidden for some reason

@Lost_N_BIOS

My friend, this is our victory! I set var2 and I successfully flashed BIOS region!!!

Now I need ideas how to change my bios dump and open additional features... and update ME FW to original... still problem with it... how should I proceed ?? I have done some amendments to my dump image in FITs but still no result..

Actually I am in ME Recovery mode..
