I was running a Pi 3b model from an "insecure" power source, aka unknown car radio USB, no idea how many amps it gives. but the lightning symbol appeared on the HDMI screen, then the screen flicked a couple of times and I pulled the power after 1 minutes or so. This was the last time with the system operating. Red LED is on, Orange LED is blinking a couple times and then stops. Also, I tried different power supplies with 1-2,5A and different cables.
Now it seems like the Pi is over overheating during boot. SSH isn't working ever, although I'm not sure about it, because the Ethernet port is blinking some times.
What can I do, to get it back online?
