So are we needing to install custom recovery then flash update zip or stock recovery then take ota? The last 2 posts seem to be conflicting. As I understand we need to be stock recovery to take ota. However, we are getting red triangle error when installing ota with stock recovery. It seems that there are system files that have been changed after flashing custom recovery that are not reverting back once we have flashed stock recovery thus preventing installation of ota regardless if stock recovery is installed. Appreciate any ideas helping us work through this.
