Banana Pi BPI-F3 16GB sudden shutdown during build – now won’t power on (red+green LED flash)

Hi,
I was using my Banana Pi BPI-F3 (16GB RAM variant) to build a tool using make -j6. The system was running fine and I was monitoring the temperature using a system monitor. It was consistently around 65 °C, and the build had reached about 80% completion.

Suddenly, the board powered off by itself with no warning.

Now when I try to power it on:

  • The board doesn’t boot
  • Pressing the power button or reconnecting power only causes a single brief flash of red and green LEDs at the same time
  • No HDMI signal, and no further LED activity after that

I was using a heatsink with thermal pads, but I now suspect the thermal contact may have been poor. The pad wasn’t very sticky and came off easily.

Is this a thermal shutdown? Or could it be any hardware failure?
Need help with diagnosing or recovering the board

Does UART have boot log output?

Is there any abnormal heat generation in the hardware?

There’s No log output from UART and there is no abnormal heat generation either.

It may be to return the product in order to determine the problem. Please contact customer service at the place of purchase.

I bought this in UBUY : link, There’s no info related to customer service, can you help me out please?

There’s no other way. You’ll just have to try this and see if it works.
