I have obtained one of our Nokia devices that another person was using prior to me for testing. The lock code of 12345 is not working. I have tried various methods to reset this device without knowing the lock code. The device prompts me to enter the lock code each time. I did the reset in which I held down the up arrow, the shift key and the back arrow. This seemed to do some type of reset as I was prompted to enter the country, etc. However, the lock code of 12345 still did not work. So, either that is not the default lock code for a Nokia N97 or this reset is not resetting the lock code back to the default 12345.
Does anyone know if either of those 2 is true?
Also, how do I reset this phone without knowing the lock code that the previous tester has entered?
