Hi guys! I'm having problem restoring my iPhone 6s Plus running 9.3.1 as of today (April 21, 2016). I decided to restore it because it lags somethings maybe because it has lots of applications and other files (photos, music, etc). I got 9.3.1 ipsw on my PC, so when I tried to restore is from iTunes it gives me an error (1), so I put my device to DFU mode and tried it again, it restore my iPhone but when it come to restoring the firmware it gives me the same error (1). I checked the web about error (1), it says its a hardware issue specifically the baseband(BB) chip. I tried to restore it several times but I got same result. So I decided to download a fresh 9.3.1 from itunes but it gives me prompt message saying 'The software for the iPhone "iPhone" was corrupted during download' so I went to ipsw.me website and tried to download iPhone 6s Plus 9.3.1, but after clicking Download, nothing happened. But i tried to download other ipsw like for my iPad and it went fine and it downloaded the iPad firmware. How come iPhone 6s Plus is not working? I think my phone has no hardware issue but the Apple Server has. Any idea guys? Can you guys try to confirm if you can download iPhone 6s Plus 9.3.1 ipsw. thanks
