I went trough all topics of this forum to find a solution to my problem, but i didn't found one. I about a month ago installed KMS 8.0 version in my Nokia E50. I also turned on the anti-theft function. One time i forgot for enabling this function and put in my other SIM in that phone. KMS reacted as it should - blocked my phone. I tried to reboot it, placed my old SIM in phone to unblock it - phone remained blocked. The worst is that turning the phone on KMS ask me to enter code - which I don't remember. I tried any possible codes that i would have created but no one of them matched real code. Is there any way to unblock my phone?

PS. I received the e-mail message saying: "A new SIM card has been detected!
Your phone is currently being used with this phone number: (my old number here)

Kaspersky Mobile Security"

PSS. Phone also has security lock code function on.

saturn007: you have to try to remember your secret code. There is not any other way to unblock your phone.

Thanks for nothing worth help. Actually I found solution by myself. I've done hard reset which deleted whole my phone memory including KMS. It's easy for you to say ' you have to try to remember your secret code' if you haven't experienced this kind problem by yourself.

I can only advise not to set a code, if you cannot remember it
