So im using FBI to install CIAs, im on old 3ds using luma3ds for cfw. anyway. tried several times to install and at the end of the install it fails saying "failed to install CIA file. Result code: 0xD8E0806A Level: Permanent (27) Summary invalid argument (7) Module: AM (32) Desc: Cert signature or hash check failed (106). so i go to the eshop and i notice that it says i have already purchased mhg and that i can re-download it. but whenever i try to download that it fails at 99% saying error code: 005-8034, sometimes it says a different error code but they are just pretty much generic. im on a 32gb sd card and ive gort plenty of space. any idea what my problem might be and how to solve it?
