One thing is, the ak2i can work on 3DS v4.3.0-10 right now, when 3DS update the firmware to v4.3.0-10, ak2i take long time to make the v4.3 patch and that make many users disapponited. But i have to say, ak2i is a classic card and the skin is beatuiful. It bring so many happy to users. Even though now 3DS update the firmware to v4.4.0-10 again and it blocked all cards. After dstwo and r4i gold 3ds released the patch, there are so many flashcart still in block and users wait for the update patch. I believe ak2i is in progressing and will bring us surprise.
Before the official released the patch, the v4.3.0-10 update patch was appear on famous forum and i tested it. It is great. Please see here to check the details.
And finally, they released the patch on the official and at same day, they released a new version AKAIO 1.9.0. That means this team is still being there and working hard on their cards. As one of the famous cards in the market, look forward to ak2i.
