Its true.

I cannot unlock me N-Gage-QD anymore. The cause is the 5-times-attempts to type the +pw#xxxxxxxxxxxxxxx+7# code with no success.

The website with the calculator program online doesnt told me about the only 5 attempts and now the message : "Not Allowed" or "Cannot undo Restriction" (my is portuguese : "Não permitido") is showed every time I try a unlock code.

Everybody knows the N-Gage-QD doesnt have cable to USB Communication. So how to solve my problem ? Is there a way to do this in my house with no special hardwares ?

i´m afraid not. after you try to unlock it 5 times and failed you must use a box to ulock it. i don´t advise you to go to nokia because they will know that you tried to ilegally unlock the phone.

Thanks friends... My problem is solved. Any store in my city has the equipement to do this unlock thing !
Just paying $12 and waiting for 1 minute and 30 seconds.
ok now !
