Hello guys, I am new to this forum. Can someone please direct me to the right post which explains detailed instructions on how to change from CE to FCC for the Spark? I do not have an Android phone but hold an Iphone X. Thank you so much!
If I remember correctly, you have to borrow an Android device and do it like the video below.
After completion, you can use your own IOS device.
If upgrading firmware on the Spark, you have to perform these actions again.
