I am new to the Car2Play things .. i did the update yesterday, and my dongle is broken.
Is there a guide or tutorial for downgrading the car2playAir dongle?
searched since yesterday, but havent found anything that helped me.
This thread has info on updating the dongle using a USB stick. See the first post.
You'll need a U2W_Update.img firmware file to load to the USB stick. Firmware from 6/17 or 6/19 seems stable for folks.
This link is used to download the .img files. Change the date in the URL to point to different folders.
However, it appears neither the 2020-06-17 nor 202-06-19 work anymore.
