Unlocking instructions

[afroman]

I saw that there are few different instructions for unlocking nokia phones - so I need somebody to verify and tell me what instruction to use. I use World Unlock Codes Calculator v4.3

1st
From the forum and in help bar of the World Unlock Codes Calculator program:

Type #pw+CODE+x# into the locked phone with no SIM card in phone.
To access button “+” you have to press twice “*” within less than a second. To access “p” just press “*” three times within one second. To access “w” press “*” four times within one second.

If your phone will not be unlocked by typing the "1" (lock 1) codes, use "7" (lock - multilock)
Remember !
You have only 5 tries, after that only a cable solution can help you !

2nd
From the World Unlock Codes Calculator site:

Easy guide to free Nokia unlocking:

1. Select phone model from list.
2. Enter IMEI number of your phone (Press *#06# on phone)
3. Select country and service provider where the phone was bought.
4. Hit the button: Calculate!
5. The software generate some Nokia unlock codes.
6. If 7 codes are displayed, use the code ending with +7 first.
7. If it does not work, then try +1, and finaly +5.
8. When phone displays "Sim restriction off" it is unlocked.
9. If only two codes are displayed (+1 and +2) enter both of them!

Codes will be shown on the form: #pw+CODE+n#
To get p, w or +, pres the * button several times.

You enter the codes correctly by removing any simcard from the phone, turning the phone on and then enter the code.

Important
You only have 5 tries to enter the correct unlocking code, if all 5 times fail you have to unlock it by cable.

Questions:
- Is there any diference typing first +1 then +7 and +7 then +1 code?
- How's that somebody directly says "Use +5 code!" - how can they be sure?
- Where is diference when cell (while unlocking) displays "Code error" and "Cannot undo restriction"?
- Is the procedure same for all types of Nokia phones - or it has something to do with warious types?

Note that I was searching for the answer on the forum (which I didn't find) before I wrote this thread!

Thanx
