[Request] Corrupted Lenovo T440P BIOS


I have a Lenovo T440P which is currently show/sounding an error message of 5 beeps, pause, 5 beeps.
I dumped my old bios and then tried flash an updated bios from Lenovo but it now shows a supervisor password upon power on (was previously running fine without any need of password). When trying to flash my old bios back, it doesn’t seem to start at all (no errors anymore, blank screen).

I’m guessing the old Bios is corrupted. Any way to get that working again?
