so I bought a Samsung Galaxy Note 3 off of ebay and in the description it did not mention anywhere that the phone was rooted and I did not want its rooted. so when I received the phone I took it to a store In town and had it reflashed to stock firmware 4.4.2 and I am NOT able to update to Android 4.4.4... I had a Samsung galaxy s4 AT&T unlocked to straight talk and I couldn't get the update because I wasn't using AT&T.. so I put an AT&T SIM card in and it updated to 4.4.4.. but my note 3 will not.. Please help. Thanks in advance!
