Baseband Chip broken, error -1. Need knowledge on replacing chip
I have recieved and old water damaged iphone from a friend that she now has no use for. I and trying to fix it in my spare time.
The phone was lost outside in her yard for the whole winter and recovered the next year. I have taken the motherboard and cleaned it with isopropyl alchocol. The phone works almost perfectly besides the baseband issues.
I originally got the phone restored, and it was on the phone activation screen. I could not activate due to carrier lock. I then got her to come over to try her SIM card and this is when it still didnt work. I assumed there was something wrong and tried restoring it. I got it restored and the phone now said connect to itunes. Itunes continuily could not activate the phone and kept giving me the error message '' cannot continue with activation at this time....."
I then went for another restore, only to get error -1. I read about this error and tried all solutions. The furthest I have gotten was I hacktivated the phone and got it turned on completely. This gave me the ability to check eveythings working behaviour. EVERYTHING still works besides the always searching for service and there is no baseband information in settings.
I believe this is a baseband chip failure. I would like to know all possible solutions that could work. I am willing to solder and rip apart the motherboard because this is just a phone for my spare time.
Is this a good question?
