Problem flashing creality 1.1.5 board to Marlin 1.1.9: Is the board bricked now?

Hey all,

Sorry, super new at this. Wanted to add Advanced_Pause_Feature and updated my 1.1.8 Marlin to 1.1.9 on my Creality 1.1.5 silent board for the Ender 3.I followed this tutorial on how to get it working https://www.youtube.com/watch?v=lAKyZd63_ns and it seems to have worked. While connected to the computer still, I was able to move around in the menu on my printer, check the about section and saw it was running 1.1.9.

Figured everything was good.I moved the printed back to it's spot in the garage and turned it on and the screen is just solid blue, no boot-up. It seems unresponsive to anything.I brought it back to the computer and tried to re-upload using the same config file and now it's throwing me a "Programmer is not responding error"Did I just brick this machine? Is there a way to restore it? Any help would be really great :)

The error message is:

See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I had a similar problem - Try re-flashing the Marlin 1.1.5

By the way it! It did not take the first time it took me several times before I could get Marlin 1.1.5 Returned to the board then It was ok Again.
And I then Flashed Marlin 1.1.9BF "bug Fix" as Marlin 1.1.9 has bugs and is not worth the flashing on any 3D Printer.
