Hello everybody, I've bought my 3DS gateway cards from teensy.co.uk for £58, the cards arrived at home, when I tested them, by following all the guide lines in the gateway manuals and videos, they didn't work, not even the reading 3ds light blinked, yes, my cartridge slot is working, I tested it with a 3ds game, and my system version is in 4.5.0. I went to their website, and contacted them with the all the steps I took, to install the CFW gateway and I even tried older versions such as 1.2, 2.0b1, 2.0b2, I tested 3 types of microSD cards but nothing worked, so I came to the conclusion that the cards were faulty. Today is the third day and I have no answer from them, I'm getting worried because I spent a reasonable amount of money. Can some one please tell me, what can I do next? because they are a gateway official reseller, any help from you guys would be much appreciated. Thanks.
