Try again that's trick work !

-Green dial key,
-Star key (*)
-Three key (3)

then press the power on/off to swtich on the 6600 phone.

Do not let go the three keys until you see the "formatting" screen displayed

5. After a few minutes, the format will be complete. Your 6600 will now be at its original factory settings.

This Work on Series 60 V2 and up not on V1 i.e 7650, 3650

I do this trickmany time but nothing changed.

Someone said that this trick can-not change the lock code to default (12345)

Now I've just reload firmware with N-Box, lastest firm ware is 5.07 NHL-2NA.

when I press "*#0000#" the phone return:

V 5.07
30-07-03
NHL-2NA

I don't know why the date not changed :frown:

try *#7370# :)

try *#7370# :)

That's not going to work coz it'll ask you for your LOCK CODE!

I've got the same problem, where the phone asks for the unlock code when I change my SIM. Is there a Nokia service centre in Melbourne where the phone can be unlocked?

Also, is it true that if you enter 5 or more incorrect unlock codes, then no matter if the next code is the correct one, the phone will not allow it?

I eventually paid the extra AU$10 and had the phone flashed to the latest firmware (it was still on the original!)

That got rid of my annoying unknown-lock code and I feel really good now!
