I'm trying to install a9lh on a friend's n3DS, and I'm having trouble getting homebrew entry points to work. The 3DS I'm trying to hack is on 11.0 (USA region), and I have access to both an old 3DS (probably 11.1 or 11.2 USA) and a new 3DS (11.4 USA) with a9lh and Luma already installed. The target 3DS is giving the update nag, if that's relevant. So far I've tried both Soundhax and OoT3Dhax, which are the entry points I have access to without buying something. I am following the Plailect guide, as I have for the other two systems I've installed a9lh on (I used Browserhax the first time, and the DSiWare method the second, which should give you an idea of time frame and system version). Soundhax gives an error and forces me to hard reset by holding down the power button. I used the microSD transfer option in System Settings to transfer the actual file over to the target 3DS as opposed to going through the process of opening the battery cover (I don't even own a screwdriver capable of opening it); could that be causing the problem? As for OoT3Dhax, it's not even installing with the exploit installer homebrew. I'm using the friend's retail cartridge, no updates or anything, and smealum's hax installer from the homebrew menu. My 3DS just sits there and does nothing at the homebrew menu, and I've left it unattended for five minutes or more. Is it supposed to take a super long time and not look like it's doing anything? Can I install the payload manually through SVDT or JKSM or is only Powersaves usable, and if so how?
