How to Flash a Xtrend ET8500 receiver by USB

What you need before we start:

1. A USB stick formatted to FAT32. (Preferably genuine Kingston and no larger than 8GB in size to prevent compatibility issues while flashing the image).
2. Flash Image. (LINK BELOW)
3. Compression software such as 7zip or WinRaR.
4. Low Level Formatting Tool (not essential but recommended).

Lets Get Started:

1. Format a USB stick to FAT32.
2. Download the Flash image and extract it to your desktop.
3. Open the folder you extracted to your desktop, for example WooshBuild-ET8500-v6.rar , you will see another folder named et8500, this is the image file. Copy the entire et8500 folder directly to the root of your USB stick.

Flashing the Receiver:

1) Power off the receiver
2) Ensure no other USB devices are plugged into the receiver while flashing.
3) Insert the USB stick containing the image files into one of the USB ports on the receiver, rear USB port is advised if possible.
4) Power the receiver on.
5) When the two colour touch power button on front panel of the receiver starts to blink, touch it to start the flashing process.
6) If successful the receiver will reboot it self after the flashing process has completed.
7) Remove USB stick that contains the images files.

The flashing process should take approximately two to four minutes to complete, while the receiver is being flashed, it is important that you DO NOT power the receiver down for any reason as this can cause serious and or permanent damage.

If the receiver bypasses the flash files on the USB stick and boots into the existing image instead you may need to check that the file structure is correct on the USB stick or try formatting the USB stick using the above mention HP Format tool or try and alternative USB stick.
