If nothing else on the list has helped so far, check your online phone company account or call your phone company to see if they can help. Restore iPhone with DFU Mode. If you've gotten this far without a fix to a Personal Hotspot that's stopped working, it's time to take more drastic steps. One of those steps is to restore your iPhone using DFU Mode.
