Hey guys! Due to a jack problem I was forced to change my charging flex cable on my iPhone 6. But when a put the new one I got no signal. It keeps saying “searching” or “No signal” or shows that I have full signal when the reality is that I have none. When I put back the old one with the jack problem everything it’s ok with the signal, I can make calls send messages go to 4G data … Can you help me? Thanks!

It sounds like you have a defective replacement Lightning/Audio Flex. Small parts are notorious for poor quality. You can get a good quality one here. If you ordered it from iFixit, contact them for a replacement.
