How To Update your Fantech Helios Go XD5:

Be sure to follow these steps below, and do not disconnect the USB cable during the update.

Step 1: Open XD5 Firmware Update V1.2.exe
a) Connect your XD5 to your PC by using the included USB cable. Make sure the Switch on the bottom of the XD5 is set to OFF, to make sure it's in USB mode.
b) Make sure USB wireless receiver is unplugged from the PC.
c) Click the "START" button and wait for the process to complete.

Now your XD5 is updated to V1.2!

CHANGELOG:
V1.2
- Disabled Mouse 3 + Side Button combo "Change Polling Rate" function, that affected gameplay in some games. (This Mouse 3 & Side buttons will still work as normal, and won't change polling rate when pressed together).
- Includes V1.1 Both Firmwares, all in one executable. Easy.

V1.1
- Improved stability for polling rate at 1000hz to solve the issue that affected users in rare cases.
