Breaking and entering with intent to commit a felony

Unfortunately, there are very few ways to un-do the final outcome of a court case (commonly called a "disposition."). If your case was resolved without a trial (i.e. you pled guilty or admitted guilt) you might be able to withdraw your plea if there was a technical problem with the manner in which your plea was entered. You should get the paperwork from the court, and request the recording of the plea, and give both to a lawyer for review.  If you had a trial, the time to file an appeal has very likely passed, but you can ask for permission to file a late appeal, and you could talk to a lawyer about a potential motion for new trial.  Make no mistake, however, your is very much an uphill battle, as the whole system is designed so that you cannot change your mind after the case is over.
