Security codes 5140 - Nokia 5100/6100/6300/7100 Series Black Earbud Headset Kit Consumer Headset

The error code is U2-30. Looking it up in a service manual, I can safely say the error has to do with either one or two EEPROMs on either the MFP or PCU PWB.

So you don't know or you have forgotten your Nokia Security code? No data cable needed with this new solution.

So what is a master code?
Well lets assume you have forgotten your security code. The master code is a 10 digit number that will always be accepted as if it were your actual security code.

You can then use the master code to change your security code back to what ever you like. When your Nokia handset asks you for the security code simply enter the master code.

I have a kenwood DNX5140, I NEED THE SECURITY CODE, how can I GET IT

1.You must enter Security Mastercode instead of lost/forgotten Security Code or Phone Lock code when phone asks for it.


2.you've tried to enter wrong Security Code too much times; in this case try to wait 10 minutes before entering mastercode

3.If your phone listed here, u can generate security code using this security code generator..

lost code need to reset

Hi,
You won,t be able to unlock this Phone. On This site.
IMEI Is a security encoded Phone, that allows only the authorized user. to change or unlock it from it,s network service provider.
assuming that you are the legal owner of the phone, you can take it to your local mobile phone shop, they will run a computer program on it. which will then authenticate the phone. whether it,s been reported stolen-lost or missing. and if it,s on a contract agreement with the 3 network.
If the phone is completely legitimate, and is not locked on a contract plan with 3.
your mobile phone shop will charge you approximately. £20-£35 or $50+ to unlock the phone, to enable a new sim-card to be inserted.
