How do I remove the clip 2 from demo or retail mode?

I recently got a few JBL speakers that use to be store demos.

I have them all out of demo mode except for the Clip 2.

Normal way to do remove demo mode is to have the speaker be plugged in, press and hold both ‘connect’ and ‘vol+’ till it restarts.

The Clip 2 has no ‘connect’ button. I have tried every combo i can think of..
