Okay so I fixed my BIOS by replacing the first half of the 32M file with data from another BIOS downloaded from the net. This way the GPU is detected and everything works properly.
I found out there is no touch on my laptop, the screen was probably replaced with no touch one.
I am including both 16M and 32M dump files that work and also support the AMD GPU. It should work on models 2FA50AV, 2FA52AV, 2FA54AV, 2FA56AV and 2FA58AV.
I have also cleaned the ME region for others to use, but did not verify if it is working....

Hello, I have a 2FA56AV (i7 8550U + AMD RX 540) with bricked bios (no image, 5x CapsLock LED). I have since flashed different BIOS (both 16 and 32M) but the AMD GPU and touchscreen are not detected by Windows nor BIOS menu.
Can somebody please repair my original BIOS or provide working one from the same model so all the components work properly?
I cant find the proper bios anywhere.
