Help! Infotainment screen blinking after battery replacement.

[Civic Fan 2016]

I just replaced my battery and now the infotainment screen keeps blinking (continuous reboot)and I can’t access any of the screens. Also, the USB ports aren’t working either. I have a dash cam plugged into one and it’s not powering up. The radio isn’t working either.
how do I fix this?

My warranty is up cause the car is 6yo.

Now it’s completely dead.

I called honda service and they suggested disconnecting the battery for 10 mins. It worked! Yay!
