I have a rooted nexus 7 running android KitKat 4.4. On my notification bar there is an update message to make o.s 4.4.2 , when I click on it to install the update, it restarts the tablet and the screen says installing the update, after 2 minutes the screen says the message "install error" and it forces me to restart the device.
The o.s doesn't update and notification stays on top.
I installed twrp and through that I tried updating the device but that didn't work either.
Is there any solution to this problem?
