Can't jailbreak iPhone 5c on ios 9.1?

I have a Japanese iPhone 5c and it makes the shutter sound which I can't turn off. I'm on ios 9.1 and have been trying to jailbreak my phone to get rid of the sound, bit I can't seem to jailbreak it! Any ways which will definitely work? I have a windows computer.

See how you like pangu I use it for all of my jailbreaks
