no sound only during calls

the iPhone 5 has taken some heavy damage but it's still working fine, but when i make a call there is no sound. i can't hear the other side and the other side can't hear me, not even a dialling tone. i checked the earpice and the microphone with the voice memos app and it works fine, there is also good reception and i can surf the web and use other apps like Skype and whatsapp.

i did a little digging on the internet and some say the problem is the baseband chip U501_RF, is that true and if so how can IFIXIT?

Hi nicolasphilippides

I figured it out. you will need to reflow the baseband chip. take the logic board out and with a hot air rework station heat the baseband chip. i used 350 degrees celsius with air pressure on 5 with a hakko station and 4.4 mm nozzle, heat the chip in a circular fashion for 30 seconds.

if that doesn't do the trick or if the problem reoccurs you will need to replace 3 chips as they are all paired:

1. Hynix H2JTDG2MBR (nand flash)

2. Qualcomm MDM9615 (baseband chip)

3. U601_RF (baseband memory)

which is not that simple so basically not really worth it on an iPhone 5 IMO. thats all the information you need, good luck.

Thank you very much :)

I don't have a hot air rework station but I will try by putting the baseband under a lamp for some minutes as I did for the greyed wifi problem on a 4S.

Hope it will work :)

Can you use the microphone and record things or did not work the game .Does music player through the speakers without a helmet. If all this work it may just be the Mic antenna. Here is a solution for it. hope this helps

thanks Jimfixer

speakers and mic are working fine. recording, apps, music through the mic and everything but no sound on calls.

unlike the video the iPhone 5 chips are covered with metal casing, pressing on it doesn't work. should i unsolder the metal casing and try to reflow the baseband chip?
