I also deleted a couple Google apps after rooting my phone with king root and when I shut down my phone as I usually do at night and tried to reboot in the morning the authentication fail #9 screen with the Lg logo is all that came up. I can still get into recovery mode of course the available options being reboot, load from cache, update from adb, wipe cache partition, factory reset, load recovery from sd card etc.
What must I do to restore to factory function. There is no such thing (when it comes to Android programming) as an unmendable brick. Somebody show me the light
