I have a Samsung galaxy core 2 I rooted it and used lucky patcher on a game known as mini milatia to get rid of google ads in it but it stoped the whole google network to connect to my phone and even if I am online it did not connect to Google so I couldn't open play store as it showed no connection then I tried to factory reset on my phone but it did not help with the problem and I re-flashed tom but even it did not help then I reinstalled google play store ,play services and Google service framework but I failed to fix the problem so how can I solve this problem will reinstalling android system help and if yes please tell me how to do it. Please help
