Hello, Would like to ask how to recover acer spin 5 515-51n's bios, as i had bricked it, was a victim of windows update which lead to acer boot logo hang and loop, which lead to me to experiment on said laptop which i removed the m2 ssd drive but still the same, so i pull out the laptop's battery and also the rtc battery, then i powered on which ended up on black screen and keyboard led only looping for every 2 secs not until you pull the power. i tried to use the <fn> + <esc> with a fat32 4gb flash drive and its bios from acer's support site named as BuzzKBL.fd as some forum had said to use UEFItool to search for its .fd filename to be put on the flash. so, i pressed the keys powered it up, the reads the flash but never continues as after reading the flash the power led flashes quickly 3x then powers down. then nothing happens. need assistance for this. thanks in advance.
