I had this problem too. After replacing my battery in my iphone 5s, my phone got stuck in DFU mode. When connecting to iTunes to restore, i got the restore error 2001. After extensive research, i bit the bullet and went to a local shop to have the battery replaced yet again. The battery replacement worked. Apparently the first battery replacement was faulty. But the second replacement worked. Iphone is back to how it was.
