I know you might have done this but try it again.

Set the dns back to automatic.

Then delete the gta update.

Then clear the cache on EVERY storage device on the console.

Then turn the xbox off.

Now wait 5 seconds and turn it back on.

Then start up gta.

Go straight to story mode.

Once in story start an invite only session.


Please try it and report back if it worked or not, if you went over level 1000 and it brought you to lvl 1 then it probably wont work and you will need to either find a negative rp server or delete the character.
