I think I may have a solution that might work for those who are getting the Android with Exclamation point. It's just a hunch and I'm in the process of testing it out right now. When I rooted my Prime I removed a few preinstalled apps (AKA: bloatware) which may be a check for the system when it tries to update causing an error if something is missing.
Here are the steps I'm going to take:
- For those with rooted Primes Back-Up all Apps + Data either in TB or the ASUS App BackUp app
- Restore to Factory Settings
- Check system for Firmware Update
Maybe it will work, maybe not.
