if you recently accidentally drop your phone then you need to open it and reheat the cobba i.c or known as the audio i.c for some cellphone experts. you need to have the following things. hot air and a flux. first you need to put on a flux above the audio or cobba ic and reheat it using the hot air. set the hot air to its proper setting and slowly reheat the audio ic for 2 to 3 minutes. and then let it cool for 3 to 4 minutes and then close back your phone. then for sure it gonna have a signal.be careful of reheating the audio or cobba ic. since its sensitive and don't try to move it, just reheat it. coz if incase you move it, it will cause you phone to recieve a contact service error.

according to my previous experience most of these models can not be switched because of problems in cobba ic, the ic cobba too step aside, too often affected if the phone down. This can cause the cobba ic Solder balls off easily. Steps you should take a trial is that you need a little mamasukkan Solder flux at the bottom of cobba ic, then heat with a hot blower. when warm, gently press the surface of the cobba ic.
Note: - Do not be too hard, if not you need a new change if you do cause pressure Solder ball attached to one another (Solder shot).
Check first your charger unit for cut or loose connection. If you can clean your unit's board this could help. But if the charger IC is shot you better bring it to a cellphone repair shop.
