Canon 5D Mark II shows Err 80 with most CF cards after a card was removed too quickly while using Magic Lantern

My Canon 5D Mark II had been working fine with Magic Lantern. After someone removed the CF card too quickly after opening the card door, the camera started misbehaving. Magic Lantern warns that on this camera, removing the card too soon can cause permanent damage.
Now only one of my four CF cards works in the camera. The others usually trigger Err 80 or the camera becomes unresponsive until I remove the battery. The cards themselves seem mostly OK, because they work in another camera.
Cards tested:
- 4GB Calumet Prospec 305x: Err 80
- 8GB Calumet Prospec 305x: works
- 16GB SanDisk Extreme IV: Err 80
- 64GB Calumet Prospec 505x: Err 80
I have already tried installing and uninstalling Magic Lantern from the one working card, and I also reformatted the failing cards on a Windows PC and in a Canon 20D. None of that changed the behavior in the 5D Mark II.
Is there anything else worth trying, or is this likely to need service?

About the only thing you have not tried that might help is to update/reinstall the firmware for your 5D Mark II. The last version listed at Canon USA's support page for the 5D Mark II is version 2.1.2
There are instructions that become visible when you click the "select" box for the listing of version 2.1.2. They tell you how to download the zip file, extract the files contained in the zip file, and where to find the .pdf with installation instructions included in the contents of the zip file.
If that doesn't work then your only other options are to either deal with it by only using the one card that works or by sending the camera to a Canon authorised service center to see if they can reflash the camera's boot files.
You're actually very fortunate that the camera wasn't totally bricked by pulling the card out while the camera was trying to read or write to the card.

Generated from our catalog & community — verify before relying on it.
A sensible next step is to reinstall/update the Canon 5D Mark II firmware using the one CF card that still works. A corrupted firmware/boot setup is one plausible cause after improper card removal, especially with Magic Lantern involved.
If the camera still throws Err 80 with the other cards after reinstalling Canon firmware, there’s probably not much else you can do yourself. At that point the practical options are:
- keep using the camera only with the card that still works, or
- send it to a Canon-authorized service center to have the firmware/boot area checked or reflashed.
Since the other cards work in another camera, the cards are less likely to be the main problem. Also, because the camera was not completely bricked, you may have avoided the worst-case failure. But persistent Err 80 with multiple otherwise-good cards suggests the camera likely needs professional attention if a firmware reinstall does not fix it.
