Bluetooth speaker wont turn on

I tried to factory reset my JBL Flip 3 so that I could pair it to a new device. I apparently did it incorrectly and now my speaker will only turn on when it is plugged in, but none of the buttons will function. I originally held down the bluetooth button and the volume up button until a red light came on and the speaker shut down. After that it would not start up again and is unresponsive to anything I try.
