Can anybody explain, please, how to unlock correctly 5110/6110?
 

I try nse-sp v8.0, phone doesn't say 'sim card not accepted' , but it doesn't see other networks, except to which it was locked.
How to reslove this problem?
Thanks

Mail me, I have the correct software, which has worked on hundreds of phones for me. I will send it to you. Mention this forum , so I know it's you.

This seems to me like you have N5130 for GSM 1800. Is maybe that your problem.
