Though it won’t be as compact and slick as the original Shield remote, any one of the many Harmony Universal Remotes will replicate all functions of the original. Here’s an example:
My personal experience with this: Configured to Chanel Master Stream + DVR / Box, Air TV player, Bluray player, Fire Edition TV, Xiaomi Mi Box and LG OLED TV.
You’ll note that the Mi Box remote is very similar to both the Shield remote and that which you ordered. A Harmony remote may not be an acceptable substitute, if you’re wanting something similar to the original Shield, but it will work.
