My electron board is doing
start with twice of breathing white
one dimming blue
blinking green for about 30 seconds
then 2 dimming blue
This happens after activating 3rd party SIM card with successful connection with cloud console.
Then I tried to download a firmware using cli particle flash --usb firmware.bin
I noticed the OS version is too low 0.5.x and tried to update it by flashing with different version of firmware however the board never get to working.
- reactivating the SIM card
- reflash with new tinker
- remove SIM card and re setup
- particle keys doctor
So far no success. What can I do to solve this issue?
