my FLM2B has been serving me for years but last year it bricked itself, no heartbeat, no life.
I could reflash it using th no-IP method, I got it back up, reconfigured it, all ok again.
But some time ago this year it bricked itself again. No heatbeat and of course no updates anywhere anymore. Same old.
I reflashed it yesterday 2x, letting it (re)boot ... no heartbeat. today again a successfull reflash but no heartbeat. Is there something I can do further to troubleshoot? Any serial connection internally I can tap into to maybe get a shell and see what's (not) going on?
I know it's (just) a Dragino v1.0, HW produced in 2011, so maybe long past it's service life but since I could still happily flash the device, there's still life in it. Alternatives are buying a new one but they're not available for sale anymore. Or I have to look at a completely different solution.
