Acer NITRO 5 AN515-57 need a clean bios

[SMDFlea]

Hello I'm stuck on the acer logo after changing the chipset and EC SIO. no nvme detection and uefi usb boot blocked .

Have you tried cleaning the ME firmware, and do you have an EC programmer or did you buy the chip already programmed

I tried to follow the steps to do Clear ME, but when I use FIT, I can't continue.

Thank you brothers. I replaced the IC with Winbond128, and all problems were resolved. Thank you for your thoroughness, just because the IC was damaged. and I use this bios file

check settings of your programmer, choose correct chipset and size.

I've made changes to the post, is there anything missing? Please help me brother😥

read again chipset, backup is truncated. Read the mark on bios chipset, it should be 128Mb or 256Mb.

Thank you, but unfortunately this batch is bad, the laptop turns on for 3 seconds without keyboard backlight and then turns off, on another batch the matrix backlight turns on but there is a black screen.
