Update ELC nodeGBx 8


ELC has just released firmware 1.52 for the dln8GBx nodes. This is a critical update for nodes with serial numbers 1784 through 2214. These nodes should be updated immediately.

The update fixes a critical bug
- LEDs glow static blue
- Backlight is on, but nothing is displayed
- The device does not respond to U.I. and network

After the node has been updated, it is highly recommended to perform a "Factory Default Reset" from the main menu. Devices that stop responding need to be updated in "forced boot mode". This can be done by pressing the encoder during startup.
