Firmware Update for the Celestron Nexstar+ Hand Controller

[@leonarddaneman810]

Got the Boot display and CFM finally recognizing the USB device, Nextstar+ . . . packages downloaded, update failed . . . and now my handset is useless. Can't access the Boot display . . . nothing but two lines of squares.

You can also update via a wifi dongle.

When I plug in my controller it says "User Keypad Entry" not "CFM Request" any idea on what to do from here?

NOT even close to what I'm seeing. I think there are a lot of steps, or settings left out of the video.

Having trouble getting cam to launch. Java is updated correctly on my PC. Anyone else run into this? Basically when I double click Celestron firmware manager.class to run it I see what looks like a command prompt flash on the screen for a brief moment and disappear. Nothing happens after that.

My handset doesn't even look like that. It doesn't have a Celestron logo button, but instead that button says INFO, and the menu button isn't 7, it's 3. No way to get to Bootloader mode. This is why ZWO is eating Celestron's lunch in the telescope business. Software.
