Hello guys,

After playing with to change the SSID:
echo DAO > ssid_prefix
dfu-util -d 2b04:d058 -a 1 -s 1826 -D ssid_prefix
echo ABCD > serial
dfu-util -d 2b04:d058 -a 1 -s 1852:6 -D serial

Now when i setting Wi-Fi credentials via USB i got the Red Flash SOS - Hard fault.
i do this:
dfu-util -d 2b04:d058 -a 0 -s 0x08008000 -D fac-dct-r1.bin
dfu-util -d 2b04:d058 -a 0 -s 0x08020000 -D duo-system-part1-v0.3.1.bin
dfu-util -d 2b04:d058 -a 0 -s 0x08040000 -D duo-system-part2-v0.3.1.bin
dfu-util -d 2b04:d058 -a 2 -s 0x180000 -D duo-wifi-r1.bin

And got the same problem…

Is there something missing that I should do?

I download https://github.com/particle-iot/device-provisioning-helper
and execute into the folder:
npm install
and do:
1.- Log into your Particle account, from the ‘Settings’ icon, copy the ‘Access Token’.
2.- Edit main.js. Change the YOUR_ACCESS_TOKEN to your own and change the YOUR_PRODUCT_ID to 88.
3.- Run the command to provision your Duo:
node main.js YOUR_DUO_DEVICE_ID
