XGS 2100 Zero Touch Deployment Stuck In Waiting For Deployment

Can you try to do a factory default on the XGS2100? 

Hi, LuCar:

I just did a previous firmware upgrade vis USB. Will a factory reset wipe that out?

Thank you.

You can connect to the Firewall via USB Serial and perform a Factory Reset, or, you can boot again with the USB Stick, it will effectually do the same.

That worked perfectly! Sophos Central is now showing the firewall as "Approval Pending". How do I approve it? Thank you!

Never mind. Found it. Thanks again!
