Hello! This is my first forum post and I was hesitant on making one as I figured I would be able to fix the problem myself-- but alas, after scouring these forums for hours & others, I just cannot find a solution. Let me get into the details:

My Toshiba Satellite S55-C5274 has been working fine for the past few years , but recently it started running a little slow so I figured I'd update some things-- I updated my graphic drivers and some other things, but where I messed up is with updating BIOS. When I updated my BIOS to version 5.20, my laptop started acting very funny. Taking longer to open most apps, games stuttering and running super slow, essentially my laptop stopped functioning normally. My main question is this; is there any way to revert the BIOS update? I've tried to manually however, my laptop detects that an inferior newer version of bios is detected, and won't downgrade at all. Please let me know if you help!
