JP1 Remotes

I want to create a device upgrade for the Dgtec DH-2000A digital set top box. I have tried downloading the existing ones created by The Robman but they don’t seem to work. I have tried using a URC-8060 and a URC-7950 remote. The device upgrades don’t work on any function on either remote. The learned EFC and device codes are the same as the upgrade and the protocol is Dgtec. The Dgtec protocol is not listed on Remote Master or Key Master. I have tried to create a protocol for the Dgtec remote but the remote control programmer has already decoded it as Dgtec, and I lack the experience to know how to go any further. Can anyone help?
I have been able to create other device upgrades successfully including finding discrete codes. I will add these to the site when they are complete.

Using the upgrade(s) you downloaded, are you certain you've picked the appropriate remote in KM/RM? And you also pasted the protocol into IR, and assigned the upgrade device code to a device button?

I went back after your reply and downloaded both the files again and tested them with the URC-8060 Kameleon remote. When I uploaded to the remote then downloaded again the device code disappeared. The problem was that I hadn’t pasted the protocol info. (I never knew I had to do that.) Once I added the protocol, the device code remained after downloading and the upgrade worked. Thanks for your help.
