No fast charge or pc recognition

So multiple chargers won't work on PC and will not fast charge so I can't update or go back to stock and it takes 5 hours to charge. Sprint replaced the charging port but it didn't change anything. Any ideas? I've tried multiple 5.1.1 roms and kernels but that's about all I can do it seems. Oh and I tried a full factory reset. Any assistance would be appreciated.
