Hi there, after i have replaced my battery, the 2 cameras are not working. I opened it again, plays a little bit with the speaker cable, the back camera worked. after assemble it again, I found that all of the output speakers are not working No sound from Speaker or Ear speaker or from wired headphones. i found out there is a little cut in the front camera cable. May be this is the problem, but why the sound is gone in all places.
Front camera cable includes earpiece circuits and if it’s damaged it might be shorting audio circuits/IC. Try disconnecting the flex cable and if that fixes the issue just replace it. Hopefully it didn’t cause a permanent board damage.
