Many LG Models have a common error of saying Use Genuine Battery then powering off. This is a very common and fixable issue. please understand that this method will most on most LG phones but does exclude the 8100 and older models, and the exact location of the items you’ll be looking for in programming will vary model to model.

If you encounter this error you can attempt to correct the phone if you have another battery for the phone that will power the handset up.

Install the battery that is working

Type in: ##LGSERVICEMENU send (##5473784296368) on the dialpad.

enter the security code: 000000

locate: SW/HW Tests or HW test or SW/HW Versions

once you locate and select the correct field you need to find “bypass booting”

in this menu you need to locate fake battery mode select it and choose on.

Your LG will now work with any battery that fits into the phone.
