Profile Corrupt/Entire Game Achievements glitched

I was playing Assassin's Creed 4 Freedom Cry dlc today and I ended up getting the Firepower achievement for killing 5 guards with one blunderbuss shot, the cheevo popped and my console froze, I rebooted the system and continued to play with no further interruptions
or freezes, however when I completed the dlc and I had achieved 100% synchronization and the credits began to roll I wondered why no achievements were coming up, for completing all mission, doing a certain objective on the final mission, and finally for achieving
100% synchronization in all mission. I completed all of this in my one playthrough that took me about 7 hours.
Now, as soon as I got back to the game my console froze again. I rebooted it and this time I'd sign into live like normal, but whenever I ran a game it would kick me offline and wouldn't allow me back on live, but returning to the dashboard would sign
me back in, I took this as my profile being corrupted and deleted my profile and recovered it, now I can't even run a game without my console freezing. I tried to start the game and THEN sign in and as soon as my profile signs in the console freezes again,
I've deleted and recovered profile several times, I've cleared my cache, and I've uninstalled and re-installed the disc. I don't know what else to do and I would really like my profile and achievements to show up. Help please.

Faulty/Unobtainable achievements

Once you have unlocked an achievement on a game it can not be removed from your profile.

Glitched achievements are down to the developers to fix,not Microsoft.

Do agree that glitched achievements are annoying though

 

missing achievments Gears of War

Did it have to do with when you profile glitched your achievements because your first 5 achievements deal with completing the game. Just a guess....

 

Hey chaosdpunk7193.

While it may not have been intentional (the forum software does have a habit of not behaving itself), there's no need to have two threads on the same subject.

I'm going to ask the mods to lock this one. We'll continue troubleshooting over here.
