Offline charging is being able to charge the phone when it is powered off. The stock rom on many phones has this feature so if you totally discharge the battery you can plug it in and charge it up. If you have an aftermarket rom that does not happen when you totally discharge the battery you end up in a boot loop. The phone starts up when you plug it in and it attempts to start. It wont fully boot because it runs out of juice then it attempts to start up again and it keeps going in this loop.
With aftermarket rom's there seems to be problems getting a offline charging mode in them to work properly. I know nothing about coding or building roms in general so i cant say what the problem is or why its there.
So with aftermarket roms you have 2 choices really if you drain the battery totally. Take the battery out and put it in some other charger. Plug it in to a charger and hold down the correct keys to enter recovery (lg optimus one home + vol down + power ) and let it sit in that mode for a minute or 2 then reboot the phone.
Would be nice if the aftermarket phones supported offline charging but there are plenty of ways to prevent this problem and even ways out of it without going too crazy so its not much of an issue anyway.
