My device is a allview vivaq7life and I used kingo root .I reseted my device ,but yet,no result. I didn't remove the root. Because I reseted the device ,I have no apps and I can't install any ,even if I tried using the internet to download apps ,I couldn't. I have no accounts on this device. How can I fix this problem?! I could access browser, messenger, Facebook and other apps, but now I only have the browser. Sorry I tried downloading and it worked!But the main problem remains...
Download flashable android zips and flash it via recovery. Try this
Kingoroot would have messed with your system partition leaving your phone unstable. In order to get everything at right place you need to flash your phone's factory image or simply install original firmware that came with your phone installed by OEM. You may get more information about your phone state at OEM'S website
