Hikey Board wont boot after restart

Hello Guys,

like the title says, after one week utilization, my 970 board wont boot after restart. I have tried to reflash the same lebian_9 build and nothing changed. My monitor detects when the power is on, but that’s all, it doesnt show the desktop.

any advice?
Thanks
Théo
