This RPi 3b+ has been running since Nov 2021 without any issue. Due to a change in iSP, I have to move to a new WiFi. Shortly after, I shut off all power due to thunderstorm activity. When I restarted the everything the metrobridge would never connect to the router. I moved it to a location where I could attach a monitor and a ip cable. When restarted & would to an openWRT prompt, and then move to "/dev/sda1: can't open /block/dev"

Is this a disk issue or something else? If it is a disk , can I flash a new image to a regular disk and use that for the 4-5 days it will take to get a replacement ? Or even re-format and re-image the existing disk and use until a replacement arrives?

Thanks

Found out by accident that if you boot the device without a network cable, it continues on to a system prompt. At that point the is seems to be functional.
