iPhone 4s Error 50 - GSM-Forum

Yasser · 08-07-2016, 00:22

Hi,

I have an iPhone 4s for repairs. It has the iTunes logo on it. I have tried to restore via iTunes several times but it fails around 80%-85% while updating the software update. This failure is happening while the 'Firmware in being written'.

I have read that it has to do with the Baseband IC.

My questions are:

1. Do I first try to reflow the Baseband IC and see if it works or not?

2. Do I remove the Baseband IC and reball it again and try and test?

3. Replace the Baseband IC with a new one? If so, do I need to reprogram it or just straight replace?

Many Thanks in advance,

Kind Regards,

Yasser.
