what can i do to get a new visa

Unfortunately the issuance of F1 visas is discretionary with US consuls. A section 214 denial is one for lack of nonimmigrant intent while the other is for inadmissibility for either conviction or finding that you have committed an inadmissible criminal offense. Perhaps you can put together a package to overcome the finding of immigrant intent with all evidence of your ties and bonds to the home country and why you will return to your home country following the end of your schooling, and present that in another visa interview with the US consulate or embassy. If you can overcome the question of intent, and if the consular officer still makes a finding of inadmissibility for criminal offense, you can request a waiver to complete your schooling, and it will be up to the consular officer whether to recommend a waiver to the Admissibility Review Office (ARO) of U.S.C.I.S., which will make the ultimate decision.
