rxTools doesn't work on CN 9.2 O3DS, can't remember if anyone else said that.
It depends on a lot if it will work on CN,
We should keep record of which version works with CN and which does not,
So, if you have cubic ninja and an O3DS, could you test 9.4 and report here your 3DS version and region, if it works with CN, if it works through the browser
EDIT: i meant 9.2
