Where i could buy a replacement motherboard for jbl charge 4?thank you.
This guide has a vital flaw. Just look at the loose wire cause by a broken solder in image 16!
that's the antenna cable which was pulled out of the connector. The step of popping the antenna connector out is missing.
from where i buy or replace the motherboard of jbl charge 4?
