I have factory reset my s6 and I’ve forgot my Samsung account password. The google account I had as backup was hacked and deleted. I’ve tried contacting Samsung to get it factory reset and cleared of all accounts but since I bought it second hand and only have a written bill of sale they won’t help. They said I needed a receipt from the store I bought it from. Is there any way, website, program I can purchase to help with this. The phone is not stolen as I’d give all my info to prove I have nothing to worry about. Just need everything cleared off because the phone is useless now.
