Rak died randomly.

I need some advice.

Just finished building a solar node and wanted to reboot it. Now it won't turn on anymore. Based on Rak19007, INA219 and a DFrobot solar management board.

Green LED flashes twice. Pressing 2x and it enters DFU mode (rapid flashes). Plugging in USB constant red light. It's recognised on windows, however erasing and re-flashing meshtastic doesn't help either. After the flash/erase is uploaded, it won't reboot or let itself be turned on again :( Polarity is correct and has never been shorted.

What's going on here?
