Greetings from Colombia Mr. ThienBui. A week ago i tried to restore my original bios after unlocking it for undervolting, action which ended up corrupting my bios so i reprogrammed the xmc QH128AHIG bios chip using ch341a and IMSProg in Linux. I backed up the chip corrupted bios and reflashed a new one from the GH5XGx64_TI.fd extracted from acer's bios file.
At the beggining, i was glad cause i solved the problem, fan control is good, battery cap at 80% works, and could boot in my windows, but realized that my RTX 3050 (error 43) and many other things (like usb hub micro sd) seemed to be driverless so i reinstalled nvidia drivers and even used ddu without success. I tried replacing the bios region of the corrupted file with the .fd one, and with the old one which was a backup from just before it got damaged and nothing. Also, i tried a new windows installation from 2nd m.2 and noticed that without the original m.2 it didn't recognized it in bootable windows usb so i had to run intel std driver from the usb itself to be able to install windows, do i need a nvme patch? The laptop never had an electric problem.
I'm wondering if you can help me to solve this problem, my laptop is an acer nitro an515-57-71tt i711800h RTX3050 board GH51G LA-181P Rev:1C i'm not a professional at the topic. Thank you.
