I have to bypass the security code on nokia 6303, I'm trying whole day without success. I tried master code, by IMEI I think it's not working I tried 3-4 generators, I tried JAF, can't find the device... I tried to reset the setting by *#7780# and format with *#7370# I can't write * and # , but there's a trick when it's asking you for the password you can write 911 and click phone button and it's starting an emergency call you wait until it fail, and then you can write those secret codes, however it's not working too...
I tried, NSS, but there's "Scan for product... Error!"
Not sure if it will work. But you can try 3 keys combo. Power off the phone. Press green (call key), star key (*) and 3 and power up the phone and keep pressing the 3 keys until you get the localization prompt (country selection). This 3 keys combo works on most nokia's phones. Usually this will reset the lock code back to default. All the best.
That 3 keys combo is a brute force reset. Have you tried it? Like i said to use the 3 keys combo the phone need to be in off mode. Press the 3 keys and power on the phone and keep pressing the 3 keys. I'm on mobile now, so my search options kinda limited. I try to look for a solution(s) when i'm back home.
Yeah, I tried it, hold green call button, * and 3, while holding them in the same time power up the phone, and keep holding them, but nothing... I tried, the same, but hold and the power button with them, nothing ;( But thanks a lot for the efforts!
