NETWORK MONITOR

There is a hidden menu inside your Nokia phone. If you want to activate it, you'll have to re-program some chips inside of your phone.

1. Check your software version. You can only continue if you have v4.33, v4.73 or v5.24.

2. Take apart the phone.

3. De-solder the EEPROM (ATMEL AT 24C64).

4. Read out the data with an EEPROM programmer and save it to a file (Backup).

5. If you have v.33 or v4.73, change the address "03B8" from "00" to "FF".

6. If you have v5.24 then change the address "0378" from "00" to "FF".

7. Write the new data to the EEPROM and solder it back to the phone,

8. Power on your phone and you should have "Netmonitor" enabled.
