Hi,

I got new board last week (B450 pro4) and I tried to update to latest bios. While updating I had accidentally disconnected my pendrive.

It went to reboot loop, when I restarted the system.

I had removed cmos battery and triggered the jumper pina multiple time. However, the system is still stuck in reboot loop

Can anyone please advise if this is can fixed?

Many Thanks,
Gnana

Ouch, you probably will have to replace the board. This one does not have a way to restore a good BIOS after a flash error (Flashback or second BIOS).
