Hi,
I'm new to the forum. yesterday i plugged in a aftemarket charger to my bb9900 and it turned off. Since then i am able to boot up but the device will turn off within a minute of so. To reboot i have to do a battery pull and then the same story repeats.
Funnily, if my phone is connected to the PC or to the mains charger then it doesn't turn off.
can someone suggest a solution please.
