I purchase PI 4G-IOT but I cannot seem to get it working,and I am trying to figure out if it's a hardware problem.
I connected the HDMI and connected power 2A 5V but screenstay black.
I try many options:
1. Install Android according theinstruction.
2. Remove J5jump.
Still no screen, Nothing on the display
Thank you for your reply.
