Q: Is unlocking illegal?
A: Unlocking is not illegal, but it might void the warranty of your provider. check the contract with your provider to be sure.

Q: Which ASIC type shall I use with my model?
-ASIC 7: 6650 and 7600.
-ASIC 5: 3650, 7650, 6600, N-Gage.
-ASIC 2: all others.
There is also one ASIC 6 model - nokia 6230. Currently it is not possible to calc codes for this model.

Q: Which box-serial/key-code shall I use with my model?
A: Always use v2 (33820) except when that doesn't work (try the New Griffin code - 34144), or if you are calculating a code for 1100 - then use Griffin Clip (33552).

Q: Which code shall I use out of the seven?

Q: I have correct codes, but still get Code error, why?
A: Some phones are not locked out of factory, try using another simcard, and don't use the same code more than once. If you are sure the phone is locked - double check all the details again. If nothing works - use a cable and read the configuration key using bWinlock, and use that as the network code.

Q: Which networks have special codes?
A: Currently there are 3 networks that have special 8-digit network code. these are:
-Fido Canada - 30200001
-Debitel Denmark - 23800001
-Virgin UK (3510i only) - 23400001
some also have special network code for some models only:
AT&T U.S - Usually 30138, but for some 3650s - 24407.
Note: This information is not that important, since the calculators have a list with networks

Q: What is the difference between locked and blocked?
A: A locked phone is a phone that is locked to one provider. It will only accept simcards of that provider. If you try to use another simcard you will get "phone restricted" message, and you'll be asked to enter a code.
The codes generated with the calculators can open this lock.
A Blocked (Barred, or "Blacklisted") phone is a phone that has been reported lost or stolen, and it's imei was barred. A blocked phone will accept the simcard, but will either get no signal, or get signal but will not let you make calls.
Codes will not open this lock.

Q: Do you enter the network codes of the cellphone or the country where i will use it?
A: You enter the network code of the cellphone, the one you baught it from.

Q: after the 5th trial could i be able to unlock without cable?
A: No.

Q: if i need to use the cable what software do i need?
A: Generally, If the phone is older than 7210 (all the monochrome dct4 models, except for some software versions) you can use a normal mbus cable, along with the JIC unlocked software.
If the phone is newer - you will need a box like griffin to unlock it.
There is also the bWinlock software by b-phreaks. It's unlock function requires a dongle, but if you have wrong codes, and you haven't used your 5 tries, you can use it to read the correct network code from the phone using a cable.

Q: I entered more thatn five codes but how am i supposed to know it is hard locked because it still lets me enter codes but all of the codes i enter don't work

A: You can't know that with wrong codes. But when you enter the correct code - you'll get "Cannot undo restriction".

Hi there!
I have 1 question for ya.
What settings do i need to use to get good codes for my 6230?

Both Unique online calculator and NFree wont "support" this model.

Thx for any help.

the calculators right now really don't support this model..

it is asic 6, which is currently impossible to calc codes to..

i believe it will soon be possible.. and i also have a feeling about who will make it this way :rolleyes:
