BIOS update failure
Hi everyone, I recently bought a used GF66 Katana and tried to update the BIOS. I downloaded the file from the MSI website, loaded it onto a USB drive and launched the update from the BIOS. Everything seemed to go smoothly, but after the BIOS flash completed the laptop turned off and the power button started blinking rapidly. I waited more than 20 minutes but nothing changed, so I tried holding the power button for 30 seconds, and pressed the reset button with a pin for 30 seconds — but nothing worked. Right now, if I unplug the charger the button stops blinking, then when I plug it back in it blinks slowly at first and then goes back to blinking fast like before. I really don't know what to think — what could have happened? And most importantly, how do I get out of this?
