Have 2-week-old Lg v10 H900, new, unlocked. It would not upgrade with LG Bridge or OTA, saying

[Yasirrrrrr khan]

I made a mistake with my lg v10 h900 at&t to flashed an update kdz file h900w. It shows the Marshmallow is up but now I get errors like "com.android.settings has stopped", "LG VPN has stopped", and "lock screen settings has stopped". I cannot configure/initiate fingerprint scanner, and device reboots when I uninstall an apk .I need help thanks in advance.

Flash the AT&T ROM to it. One phone won't work with another phone's firmware. (You'll be flashing a ROM that doesn't have any of your things on it, so back up everything that you don't want to lose.)
