I had this weird glitch where i didn't finish up the quest of return the helm of winterhold and then continued the story. after that because of the advancement in the story the jarl was exiled to live in winterhold.
to complete the quest i had to cheat unlock the door and give him the helm and everything worked all right.
but now i want to become the thane of winterhold, i don't know what was supposed to happen after i gave him the helm but i needed to get a quest that would tell me to help 3 people so i could become the thane of winterhold. but for some reason nothing happened.
