Why change your firmware to a generic version?
1. Most people want to debrand their phones in order to get rid of the brand specific settings / limitations, and rubbish that the service providers have put in. For example, the three logo that comes up every time the phone gets switched on, or the favourites which cannot be deleted.
2. Updates released by Nokia come out for the generic versions earlier as there is no need to be tested and approved by vendors. (which can take months, if at all.)
What is your product code?
Typing in *#0000# into the E71 will report your product code to you. Write this down for future use. The product code is representative of the different versions of the phone, as well as region and vendor. So changing your product code allows you to 'represent' your phone as a
generic regional one, or one sold by a certain vendor. Changing your product code will void your guarantee, however, simply change it back to your original one to avoid any problems. Also, as there are different versions of the E71 out there with different hardware, you cannot simply change your product code to any E71 product code you find. Do a proper search for your appropriate product code.
How to change your E71 product code?
You have to connect your E71 to your computer with the USB data cable it came with, and use the Phoenix Flashing software. The instructions are as follows;
The new version (2009.20.010.39068) of the Phoenix flashing software can be found here.
This version is significantly improved to include:
- preconfiguration to use USB connection
- uninstallation of remaining drivers and runtimes
- reduced size by 15mb
This should solve the previous problems of NSS not detecting the E71.
The basic method to debrand the E71 remains the same however. Here are the updated screen shots to make things clearer:
1. After installation, select File -> Scan Product.
2. To view your phone info, select Product -> Phone Information
3. Next, select File -> Open Product, your product should be automatically selected for you.
4. Select Product -> Production Data Edit -> input your new product code -> click 'write'.
If you get an error saying "production code not valid. Production code must be 7 digits.", try inputting "1111111" or "1234567". When you are done, remember to select File -> Close Product. Restart your phone.
You should now have an E71 with a generic product code. Start up Nokia Software Updater to get the latest firmware. Alternatively you can update your firmware offline.
