I found this post but I can't confirm if it works...
Finally got it working. Here's all the steps...
- Uninstall Halo: MCC
- Shutdown (press and hold Xbox button on console)
- Power-up
- Install Halo: MCC from disc (didn't bother logging in to Live first)
- Immediately told I needed the big (3.2 Gb?) update for MCC
- Proceed with update
(Several hours later, install and updates are complete and console has powered off due to inactivity)
- Power-up
- Login to Live
- Run Halo: MCC
- Select ODST
- Not installed. Do I want to go to the Store to get it? Proceed
- Install ODST
(Several hours later, install and updates are complete and console has powered off due to inactivity)
- Power-up
- Login to Live
- Run Halo: MCC
- Select ODST
(hold your breath)
It works!
