Just bought an X708 V1.2 board and put on my Raspberry Pi 4 Rev1.0 board. I'm using 2pc of 18650 battery.
There is an weird issue i encounter, when i put in a few USB devices like a pen drive and smartphone for tethering. The 4 green LED on board keep flashing in random order and eventually the blue LED start blinking slowly and my Pi shutdown not long after that. Sometime the blue LED will start blinking rapidly and my Pi will reboot shortly after that.
What is happening? Is this behaviour normal? How do i fix this?
