you can revive it back using known good bios yet there is some problem such as slow perforamnce camera not working keyboard backlight not working.. so unlocking the orig file is the best move.. and next time make atleast 3backup(click read and save not copy paste) before erasing the chip

Rules: Always read two times and compare with hxd to exclude other problems and time. When the two files are identical, only then go to the next step!
