I have a unmodifed console connected to xbox live to download the free dlc map packs. I copied the dlc map packs onto a usb. Then with a RGH console I copied the dlc map packs from the usb to it's hdd. When in multiplayer the dlc maps don't appear in the menu. I also used the Halo 3 title update from digiex.net and 1.2 appears on the menu screen. How can I get the map pack to appear on the RGH console without going to xbox live on that console?
If you copy the content to your PC, you can unlock the DLC with YarisSwap: https://digiex.net/threads/yarisswap-download-patch-content-to-work-on-a-jtag-rgh-xbox-360.3122/ It should then work on the RGH Xbox 360 perfectly fine when you copy it back to the USB drive.
