Charging not supported by accessory?

Recently I updated my iPhone 3 to 6.1.3 and suddenly my charger won't work… Any ideas on how to make it work? I restarted my phone, cleaned the port, charged it to 20%, etc. I did a lot of ridiculous things to get it to work and it didn't! The pop up just keeps coming… Charging is Not supported by accessory.

Yeah this happened to me once. Sometimes updating may have newer code and the charger can't recognize the device due to the latest update, resulting in the "Not Supported by this accessory" error.

Unfortunately the only way I got it to work was to either:

1) Restore (sometimes works and sometimes doesn't. Do are your own risk)
2) Just use the normal USB to 30 pin connecter that comes with your iPhone.

Sorry for your problem and best of luck!
