The Odd Awkward 7110 or 6210!!
Ok very rarely you may come across a 7110 or a 6210 where all the above methods fail. The reason for this is that Nokia introduced an additional security feature in these models. If the security code has been entered incorrectly many times then it can't be read or reset at all! The only way around this is to either full flash the handset (including eeprom area) or flash a small file called an eeprom cleaner to the eeprom area of the handset! More on this when I get time. :-)))
You may need to download an additional file to get Mbus by Maestro to run - MSComm32.OCX - This file can be found in the downloads section. (place it in your windows/system directory)
Remember when using Fbus by Maestro DO NOT touch the Vibra control option. It can kill your vibration functionality!! Also if using the above method on a 7650 or 3650 do not remove cable/battery whilst the symbian OS is booting up or down.
