Mr Yellows8 released a new exploit on the 3DS-ctr-httpwn which allows users to bypass required sysupdates on older 3DS firmwares. Users can go to Nintendo eShop, or DLC content through ninjhax 2.7 on older firmware versions(v9.1-10.6). In other words, you do not need to update your 3ds console to the latest firmware now and you can go to eshop through HBL directly.
The user instruction of ninjhax 2.7 is the same as ninjhax 2.0. Ninjhax 2.7 can support OLD/NEW 3DS v9.1-10.7. You can use sky3ds+ to go to homebrew launcher. We tested it with 3DS Ver 9.5.0-20J and it works well. There seems some problem with 3DS10.6.0-31
