Hello.

I have iPhone 6 plus and its SIM lock with operator NTT Docomo. Nobody can unlock it, but year, when i find it, i`m use it for gaming in wi-fi mode:) Without sim card.. After that i give it for SIM unlock and they install newces iOS and dont unlock it.. Now its like brick. When i turn it on, i cant do nothing without Japan sim card and iTunes also say: insert sim card. 

I`m dowload iOS 9+ and try install it with iTunes in DFU mode, but there is some error 3194.

Can someone help me with info, how i can downgrade iOS for later version like 9+, becouse in this version i can use it like iPod, without calling.
