Unbrand your Cingular E62!!!!

Well its finally happened! After 3+ long months of waiting for someone to fix the JAVA crippling that Cingular placed on the lovely Nokia E62, some smart person figured out how to unbrand/reflash the firmware to the stock Nokia unbranded firmware.

As any of you who own a Cingular smartphone/pda know, its J2ME capabilities were severely crippled due to Cingular's custom firmware installed when you purchase the phone. When using any JAVA app that required access to the net, it would CONSTANTLY prompt you for access to the web. Suffice to say using fun applications like Google Maps became extremely annoying. Well its all gone now thanks to a crafty person who unfortunately I cannot give credit to because I dont know who he/she is!

In any case, on to the good stuff: below you will find the specific directions on how to perform the re-flash.

-----------------------------------------------------------------------
1) Download and install Nokia Software Updater (NSU) from:
http://www.nokiausa.com/support/software/update_via_pc_1

IMPORTANT NOTE: Nokia Software Updater is very sensitive to software firewalls. During the many tests I have done, I found that I must completely disable software firewall, as granting full network access to (NSU_UI_CLIENT.EXE and NSL_HOST_PROCESS.EXE) was not enough to make NSU work. So, the bottom line is if you do not want an additional headache and want to receive quick results, then just temporarily disable software firewall before you run NSU in step 6).

2) Download and install Nemesis Service Suite (NSS) software in order to change the phone’s product code from here:
http://www.b-phreaks.co.uk/software.htm

3) Now we are ready to change Cingular's Product Code to Unbranded US_Generic Nokia’s Product Code which will allow us to upload the original (not modified by Cingular) Nokia’s firmware in step 6).

3.1 Connect your phone to USB and choose "PC Suite" mode (same as if you always do when sync your phone);

3.2 Open NSS and click on “Scan for new device” button on the right-upper part of the window;

3.3 Click on the icon “Phone info”;

3.4 Click on “Scan” and wait until you get "...Done" in the status string at the bottom of NSS window;

3.5 Now, in a "Product Data Edit" window check "Enable" next to "Product Code" string and type the next code: 0524513. Then press "Write" button and wait until you get "...Done" in the status string at the bottom of the NSS window;

3.6 Press "Scan" button again (same as you did in 3.4) just to be sure you still can get "...Done" at the bottom of NSS window;

3.7 Right click on a small icon (located above "Device Info" button) and choose "close device";

3.8 Now you can completely close NSS. We do not need it anymore.

4) Disconnect USB cable.

5) At this step we will reset the phone to the factory configuration:

5.1 On your phone press several times Red button, so to be sure you are in an "Idle Screen";

5.2 Press * button

5.3 Press # button

5.4 Press 7 button

5.5 Press 3 button

5.6 Press 7 button

5.7 Press 0 button

5.8 Press # button

At that point you will be asked if you want "Restore all original phone settings". Answer “Yes” and confirm the code (which is 12345 by default. Be careful and verify that you are typing a numbers, but not symbols).

When you provided the right code, your phone will be restarted and you will be asked if to you want a read a tutorial. Answer “No” to save you some time.

6) Now we are ready to update our E62 to Unbranded US_Generic Nokia firmware.

6.1 Connect your phone to USB and choose "PC Suite" mode;

6.2 Connect your phone to a charger;

6.3 Run Nokia Software Updater (NSU);

6.4 Follow the prompts. At the point when NSU says that you already have the latest firmware and if you want to download it again, confirm it with checkmark and let NSU do its work;

6.5 After about 15 minutes, NSU will finish its work, reboot the phone and tell you that your phone software is updated and you are ready to go.

6.6 Close NSU window. Disconnect your phone from USB.

6.7 You should have Unbranded US_Generic Nokia firmware in your phone now.

Big thanks to Chris at EQO Mobile for finding this fix.

NOTE:Please be aware that this will most certainly be against Cingular's rules and they will most likely not provide support if they figured out what you did. How they would figure that out would be unknown to me but I had to say it.
