Firmware Version 2.7.1 Build 20150718

About This Release:

  • July 18, 2015
  • This update will automatically request reboot of device after the download is done and erase Lightning Server database previously used in order to utilize the latest revision's functions. There will be a re-index procedure when initially using playback from USB source.
  • Devices with firmware from Version 1.8.2 and earlier will need to update the boot code after reboot. There will be a message displayed on device warning people to not to power off the unit during this stage. The updating of boot code will take about 70 - 80 seconds. The unit will reboot after boot code has been updated.

Please make sure you do not reboot or turn off the unit during the update of boot code, or else the unit will no longer be able to boot up (will have to return to factory for flashing the boot code).


  • Fixes the issue that playback may have click and pop noise when Lightning Server is scanning USB drive.
  • Fixes the issue that 2nd track in queue of online streaming will repeat twice.
  • Fixes the issue the Lightning device could not join a hidden WiFi network without password.

New Features:

  • New 3.10.53 real time kernel, resulting in sound quality improvement.
  • Lightning Server now support SMB shared folder created by Windows PC and Mac computers.
