Double-flashing SYS Light

Hi DrCWO,

I’ve been a happy RooExtend user since purchasing my box in November 2024. But after being offline for the past six months due to an extended move, RooExtend won’t boot. It starts to, but after the network light comes on, the SYS light starts flashing twice per second, a sure sign the SD image is corrupt. I see that it is possible to re-flash the image with Balena Etcher. Can you help, please? How do I proceed.

Thanks, Bob
