Hello. I bought a used phone, a full set with a cardboard box, unfortunately without a proof of purchase, so despite the fact that the number of the phone is compatible with the one on the carton, the service is hardly an option. When I bought the phone I checked, of course, the card of the previous owner. Then I made a reset and of course the phone demanded to log in to the previous Google account, and contact with the seller is impossible. At the beginning I tried to upload single-file rom, then four-file by odin, it did not help. I tried the method with a usb host, the phone can not see the pendrive. Another method with SideSync and running the browser has also failed. I managed to find a forum for an effective method of launching the browser. I even logged in to my Google account, on the second phone I received a request to authorize the new device, I confirmed, but it still did not solve the problem. I tried to download the application "samsung bypass google verify" on the phone, unfortunately the files do not want to be saved on the device. I'm just downloading rom 5.1.1, four-file together with the pit file, and in the evening I will try to repeat everything on the older version of the system. I do not know if it makes sense, how do you think? If anyone has any ideas, I am waiting for suggestions.
