Cant activate iphone i bought off ebay - help needed
Hi, I just spent £100 on a 2nd hand i-phone 6 off ebay.
Ok, so when i got it home i switched it on and gave it a factory reset but then it took me through the language set up and got the wi-fi connected, but then took me to a page saying i need to enter the phones i-cloud/activation credentials before i can use it. I then found this was because the phones previous owner had it secured onto findmyphone and i need to contact them for them to log into their account and delete themself. Yet these credentials were not sent to me by the sender and i've contacted the seller but they dont know the original owner and they are unable to help further and told me i shouldnt have factory reset it as it was my own fault.
Now i'm at lost because i dont know what i can do. Is there any firmware i can download where i can erase the phones OS and re-install it or is the phone no use at all??
Any help will be appreciated. Thanks
