I have the version 8.1.0-0U. I bought a Gateway 3DS card because theirs team confirmed me it will work, but after I purshased, nothing seems to work and I lost contact with them, so I'm stuck without ideas. My console version does not permit to open the browser. That means that any exploit using browser won't work. Blue card is blocked in this version. It generates an error: "An error has ocurred. Press and hold the POWER button..." Is there any other way to launch the Gateway Menu?
