So my friend wanted me to root her phone. We did this using KingRoot and installed Freedom. Now, I did a factory reset yesterday thinking it would fix because the phone was only rooted using an app, but to my surprise it didn't work. Anyway, I booted up the phone after restore and tried signing into my Google Account with Play Store and even tried again later with the phone itself. It failed and kept telling me that it 'can't establish a reliable connection to the server. This could be a temporary problem or your Android device may not be provisioned for data services. If it continues, please call Customer Care.' After trying a few times, I re installed the KingRoot app via APK file and attempted to unroot, I think it worked and checked the root status with RootChecker Basic and it said 'Sorry! Root access is not properly instaled on this device.' I tried logging in again after attempting to unroot with not luck once again and the same message as before. The only way I can install things is to download the APK files but I would also like to log into my Google Account to set up my device and downloading and installing APK files can be rather tedious. My phone is a Samsung GT-191152. Some help would be MUCH appreciated! Thank you!
