Hello, how are you? I want you to update my device, but I did not find it in the list of compatible devices. My device is D-link dsl-2740u, and this is the product link from the company’s website. Thank you.
It doesn't work that way, there is no one taking wish lists. Either you do the development for your device yourself, as you're the only one who has the device on their desk - or (likely) no one will.

…and chances for that device are essentially zero anyways.
