Question Oukitel can't find GND

[TheYikes]

Hi! I've got an oukitel c16 pro. Long story short it's bricked and in order to flash it I need to find the "GND" point. If anyone can help me out I'd appreciate it! Here's a picture of the board:

GND is an abreviation of ground, which is all over the place on most PCBs. A convenient location to connect to ground might be that screw on the right edge of the board.

Hi Mr. Evil (wicked name) I thought maybe it might be the back of the sim tray?

 

[Mr Evil]

Yes, the sim tray is almost certainly connected to ground too.

Thank you again Mr Evil.
