I have been working all weekend with this little guy, but all of a sudden after one of many restarts it got stuck blinking green. I tried putting it in safe mode and reflashing tinker but kept saying it failed.
I then did a WIFI reset on it (hold RESET for 10 seconds until flashing blue LED), but each time I try to go through the setup process using the Tinker app on my iPhone it gets to the last step (verifying device ownership) and fails.
I have tried even enabling my guest WIFI network without credentials but same problem. All my other devices are working fine. This thing is just dead now, constantly blinking cyan (and occasionally flashes orange).
Can someone please help, surely this thing has not become a $20 brick from a simple reboot?!
