Phone is not turning on
If your LG KP100 is not turning on, try one of the following steps:
Phone battery has lost charge
Use the charging cable provided with your phone to charge the battery before attempting to turn the phone on again.
Note: It may take up to 30 minutes before the phone indicates that the charging has begun.
Battery is broken or not functioning
If you have an extra LG KP100 battery or know someone who does, try to get ahold of it. Replace your current battery with one you know works. If the phone now turns on, you know that the old battery is the source of your problem.
Screen does not work
It is possible that your phone is on, but your screen is unable to display anything. Try to place a call with your device. If it is successful, follow the necessary steps in the installation guide to replace your screen.
Phone will not connect to my computer
Your computer lacks the correct software drivers

The USB cable is broken
If you have access to another working USB cable designed for the LG KP100, try to connect your phone to the computer with the working cable. If your phone successfully connects, replace your old USB cable with a functioning one.
The keys are not working
The keys have debris within them
If the keys are not responding, check to make sure there is nothing loose within the keys. If there is, clean them off or use a compressed air cleaner to dislodge the loose particles.
There is something between the keys and the motherboard
If the previous step did not work, follow the guide to replace the keypad found here.
Motherboard needs to be replaced
If the two previous solutions prove to be ineffective, you may need to replace the motherboard for the entire device due to the key contact points going bad. The process to do this can be found here.
The battery is unusually hot
When doing many things on your phone for an extended period of time, such as phone calls, using the internet, playing games, etc. the battery can become very warm. This is normal behavior that shouldn't be worried about. If the battery becomes too hot, however (too hot to touch), you need to contact an authorized LG Service Center.
