iPhone 6 baseband problem
Hey guys, so two months ago I bought an iphone that was somewhat faulty. Sim card didnt work but that was ok for me since I dont use the phone that much for purposes other than wifi. Recently, me not knowing that an iphone that doesnt support sim card has a baseband problem, i tried updating it via itunes and then i tried restoring but you know... I couldn't. I kept getting itunes error (-1). Now that I know it has something to do with baseband what are the possible fixes for that. The attached pic shows my phone's motherboard. I'm asking for help on what can I do? All I currently want is just to restore my phone since it is stuck in recovery mode? In the other hand, how can I fix my baseband? What should I do? What should I buy? Thanks in advance.
Also notice how those two wires (?!) near the sim card tray are disconnected, is that a problem? And what's those two burned things near the baseband? Thank you so much.
p.s If I connect my phone to itunes it shows my serial number.
Is this a good question?
