[REQUEST] ASUS TUF A15 FA506IV BIOS Unlock

[badabacchus]

Good to hear. I am not sure why the other flash attempts failed. All of the backup images should have worked. Maybe there was a bad connection (very common, which is why I asked for several dumps and compared them).

For future reference, the modded BIOS from post #25 was based on the SPI backup (FA506IV.rom). I will base future mods on this backup since we know for certain that it is functional.

However you flashed the BIOS this time, I would take notes on what you did. I think the brick the first time was due to a bad connection or the CH341A flashing software that was used (or both). If you are willing, I'd recommend flashing the modified BIOS from Post #24 again and see what happens. If it results in another brick, then reflash the SPI backup (FA506IV.rom) or the mod from Post #24 (they are the same).

I'd recommend seeing if AFUWIN will allow you to flash the BIOS. At this point, that may give a more consistent result than the programmer, especially if you are using the cheap clip that came with the adapter. I had to order the Pomona 5250 clip in order to flash my test machine.

With the modified image from Post #25, do the normal BIOS menus (Main, Advanced, Security, Boot, Save & Exit) show up or does nothing show up at all?

Do you have any time to indicate to me on the above pictures where you are accessing the physical BIOS hardware to reprogram it?
I'm currently thinking I might have different hardware to you? I spent a few hours stitching the first image.

Hello,

I'm new to BIOS modding and I own this particular laptop which I want the CBS and chipset options on. Could you help me with that?

Best regards
