PLEASE READ THIS NOTICE! The GATEWAY 3DS flashcart will ONLY work if your 3DS is running an ORIGINAL FIRMWARE v4.5 OR LOWER Anything you hear about using 7.x or 8.x firmwares is in regard to amazing feature of EMUNAND which allows the Gateway to fake load newer firmwares on top of 4.5, the actual system itself MUST BE on 4.5 or lower, and then the newer firmware is soft-loaded via SD. IF your GATEWAY is running on any firmware higher than 4.5 it will NEVER EVER EVER work on with Gateway 3DS. IF that is your case, then its best to shop around for another 3DS which has 4.5 or lower firmware running on it. Sorry to break the bad news, but that is how it is and most likely it will NEVER EVER change, if it does then this THREAD with over 34 pages of replies asking the same question over and over, and with over 60,000 views will be deleted and replaced with a HUGE banner across the top of site on all pages, announcing the amazing breakthru in the Nintendo scene.
