I got AMD Ryzen 3 4100 but i couldn't boot bios so i took AMD A6 9500 so i could update it to new bios that support 4100. And when i got the bios from official asus site and when i tried to update it in EzFlash it give me a massage: Selected file is not a proper BIOS.Welcome to the forums, newcomer!
Try gradually working your way to the latest version, instead of jumping to the latest version. What processor are you working with? Also, just in case, how are you performing the BIOS update?
