Nope didn't work. Still mutes the characters and freezes at the end. And I tried online and offline from interwebs. Next solution.

Okay have you alread tried to completely uninstall Mass Effect 3 from your console, delte your Gamertag after and re-download your Gamertag in order to install ME3 after? Which model of the 360 do you own?

Cheers

Tried that and still didn't work. And I have 360 slim version.

I have a solution of my own that I give you. Make a(n) update/patch that will allow players to skip the mission and reap the benefits from the mission aka everything/every item will either be up for sale or be placed on the normandy. And you gain all war assets from the mission as well. This will help me and anyone else that has this problem. Please reply faster or get someone else not trying to be mean but the faster this is done then it will be one less to deal with. I know you have to help others as well but this wait time is outrageous. Thank you.

At this point I recommend to backup your data on an external hard drive to format your system. We went through the most basic workarounds, it might as well that this is an issues with your disk. Do you know someone who owns the game to check his/her disk in your console?

I am already using a hard drive so that's not the case. And I don't know anyone who has this game. But in past experiences of a similar issue both my and my friends disks did not work.

I meant to backup your files on an external hard-drive or other flash drive and then format your system. This will delete all your data from your console and reset it to factory default. After that, you can re-download your Gamertag profile and move all data from your external drive back on your Xbox HD.

First I don't have a computer working. And I don't have any flash drive that can hold more that 20GB so can you give another solution that doesn't involve me deleting everything.

I can understand your frustration. You don't need a PC in order to backup your data on a flash drive, maybe you can delete some data which you don't use or just download afterwards if you have a smaller drive.

I have done some research and it seems this issue was addressed in a fix from around March 27th. Could you please check if you can download the DLC directly from the XBL store or if there is a fix available in your store. Some players mentioned that doing a side mission which requires disk 2 helps as you don't need to change the disk again if you return to enter the grissom acadamy. 

Which language version do you have and what is the language of your Xbox system?
