Hi Matadeen,
Please make sure you have the correct nvs file and FW files in the /lib/firmware/ti-connectivity directory.
If the problem still occurs, please send the serial log when running all the commands as described in the link you followed, with the addition of the following commands:
1) ls -l /lib/firmware/ti-connectivity/
2) lsmod - before running the commands and after
Regards,
Barak
