The LG G4 was released in the US in early June 2015, as always focusing on high-end specifications and a refined fashion sense that makes it stand out in the premium smartphone market. Each version of the phone will have a different model number based on if it is sold by a carrier or unlocked (US or International). Some LG G4's are known to have bootloop problems.

You may also wish to try a hard reset of your phone to see if this resolves your problem.
Be aware that a hard reset will erase all your downloaded apps and user data and restore your phone to a factory default condition. It will be like when you first bought it.
You may wish to backup your data first.
Before performing a hard reset ensure that the battery is charged. Do not perform a hard reset with the charger connected.
Here is a link that shows you how to do it.
Be patient, it takes a few minutes.
My sons phone did the same thing. I cleared the cache then instead of message to turn off airplane mode it said it needed 911 installed. Somehow the 911 phone number got deleted so when I added it back in, the phone now works, doesn't give error messages and can make calls
