This is a "how to" on unbranding or getting rid of the Cingular/at&t junk on your phone. Should work for other carriers as well.
The benefits to Unbranding are:
-More RAM for multitasking/web functions
-ability to select network, which can save battery life
-ability to install programs not normally allowed by Cingular.
-some button changes, giving you more flexibility.

If you try this, you do it at your own risk of bricking your phone. You've been warned!

what you'll need

The Unlock code (if your phone is not unlocked)
Nokia PC Suite with NSU (Nokia Software Updater)
Nemesis Service Suite (NSS)
Your Nokia N75 (fully charged) and the PC data cable
unlocking your phone

Caution: If this process is unsuccessful five times in a row, the phone will be permanently locked to the New At&t Network. Do not attempt to enter the code more than one (1) time total. Instructions below will assist you in unlocking your device, if these steps are unsuccessful please contact us at 1-800-331-0500 or (916) 843-4685 from overseas.

This procedure can be done with or without the Att SIM inserted into the handset

# (press the # key, 1 time)
P (pause, press the * key 3 times)
W (wait, press the * key 4 times)
+ (press the * key 2 times)
Code (enter the code-10 digits Older phones or 15 digits Newer Phones)
+ (press the * key 2 times and it should convert to a + sign)
1 (press the 1 key 1 time for phones)
# (press the # key 1 time)
Your phone should say "sim restriction off" if successful.

One Step at a Time

Install Nokia PC suite, make sure your N75 is recognized via data cable
Install Nemesis Service Suite Software
If you have contacts, pictures etc on your phone, run a backup via PC suite
Make sure your phone is connected via USB, and is in a place where it will not be disturbed
Run NSS
Hit the "scan for new device" button (looks like a magnifying glass)
click the button "phone info"
click the "read" button
should have "product code" on the left
change product code to 0541358 and hit "write"
When done, restart phone, reconnect and check product code to make sure change occured.
Make sure your phone is connected via USB again, and in a secure place
Run NSU, and follow instructions
When NSU finishes, phone should restart and you should have a new Unbranded N75!


Enjoy!
 
Any one tried this instruction??
Damage caused by unauthorized unbrand is not coverd in the contract:(

some Unlock issue you should know

Hello xj911,

Thank you for the post post regarding unlocking and unbranding n75.

I understood all the steps, i have nemsis and nokia updater installed and I am clear on all the instructions. But i am stuck on the first step i.e. how to use a local sim for USA's AT&T N75. My uncle lives in USA and he gifted me the phone and here it doesn't work.

I also followed your instructions regarding unlock which are written below but again it threw 'invalid code' error.

# (press the # key, 1 time)
P (pause, press the * key 3 times)
W (wait, press the * key 4 times)
+ (press the * key 2 times)
Code (enter the code-10 digits Older phones or 15 digits Newer Phones)
+ (press the * key 2 times and it should convert to a + sign)
1 (press the 1 key 1 time for phones)
# (press the # key 1 time)


An another article which also guided me was also talking about the subsidy unlock code to get as the first step.

I will be grateful if you help me in this regard.


Thank You

I am havng a problem trying to unbbrand my n75.

I have successfully completed all steps (including changing the product code) to running NSU. On trying to run NSU I get a message that says "cant connect to inernet".

I went to the Nokia site and downloaded the OVI suite and installed it.

On running NSU through OVI it worked fine except I got a message saying my software is up to date and nothing changed on the phone.

Is there a list anywhere that gives all of the product codes for the N75?
