I am based in Ireland, I ordered 3 Boron404xs and all of them are not connecting to cloud.
While trying to setup these borons through app I am stuck at connecting to cloud via cellular.
I have tried the web tool to flash the device but it fails.
It is showing the same DFU flashing failed for all the three devices.
However, I factory reset them and flashed through Particle CLI, now they are with latest firmware as shown below.
All the three are flashed with firmware version 4.0.2. But when trying to connect to cloud it stops at “connection to cloud via cellular” and throws an error message again.
Can you please help me with this, it has been going on for a month now and new Boron404X is still not working, however the Boron model BRN310 has no problem connecting to cloud even after unclaiming them.
Thanks and Regards
