Hello, my openspot3 asked for an update and asked to reboot, it was flashing red and green, then I turned it off, when I turned it on it blinks yellow and doesn't turn on, I can't reset
The openSPOT3 does not ask you to reboot, it reboots during the update when it needs to. Probably the firmware upgrade process got interrupted. Please upgrade the device firmware manually. You can find the manual upgrade instructions in the user manual: https://manuals.sharkrf.com/openspot3/en/troubleshooting.html#i-want-to-manually-upgrade-the-firmware ("I want to manually upgrade the firmware" section)
