Need help with my N96i
 

My N96i went out when I finished setting up the camera in "engineer mode" and never returned to power on.
I took out the battery, chips, memory, and went back to test it with the battery installed but remains shut down.
I tried to charge via USB and wall charger but no charge or power on.
It uses MTK MT6228 Drivers (usb and com)
Help me plis !!!
