Ordering an HDMI extender, serial number is not accepted
This usually happens when you don't enter your serial number exactly. The most common mistake is mixing up the letter L and the number 1. The next is the letter O and number Zero (0). Notice the letter is more round than the number (move oval). The best way to ensure you have the serial number correct is to log into your Roku user account and copy the serial number from your devices list and paste it into the web page.
Remember the HDMI extender is only for Roku Stick players, which as the players that plug directly into the HDMI port without using a cable. If you enter a serial number for any other Roku device, it will reject as well.
