Nokia 3310 can not be swith off - GSM-Forum

bbbbbb · 01-16-2004, 21:09

I have a Nokia 3310 mainboard. I use a test jig.When I connect voltage with the mainboard, current is zero. But when I press power key the phone has some current consumption( I use a power supply and can see the current is not zero) but no matter how much I press again the power key, the power consumption remains and I must disconnect the power supply to have zero current consumption. But why power key can not switch off the mobile? I can not flash the phone successfully either.
Thanks for help
