6. If X is on NETWORK and value is different than 0, you can unlock the phone with our codes.
in case if the phone shows (X) network lower then 5 and not 0 , then it wil be refunded
in case if the phone shows (X) network - 5 means the code was not even seen by phone, cause the counter was to be lowered to 4 at least in case of wrong code

() subset 5
for such screen counter was not checked properly or the phone is bricked by software (5 locks on)
