it's easy
use
Samsung 3G online code reader (some F480 version can't be unlocked with direct unlock even after full flash, boot, reset etc...).
u will get unlock code and unfreeze code,
the F480 have a little difference from F490, because u can use the unfreeze code not like the other one.
Method to Unfreeze F480(V):
- Use Samsung 3G Online Code Reader, u will get Unlock and Unfreeze code,
- Put a non accepted SIM Card and power On the phone,
- U will get on screen "Phone Freeze etc..." and 2 Screen Key (SOS and CALL).
- Press the "Call" Screen Key, enter UNFREEZE CODE and in the Second u Will get "Network Lock" (other code will not do anything).
