I'm running a 9.2 emunand and 4.5 sysnand on my old 3ds at the moment, however i feel using the browser exploit is a little hassle and is fairly tempremental when booting rxtools to enter emunand. I thought i could coldboot to emunand using the rxtools.3dsx, however without a 9.2 sysnand i cannot install homebrew. I was planning on upgrading using my NAND.bin - however guess which idiot can't find it. I want to know if there is another way to upgrade my sysnand, or a way to run hbl on firmware 4.5? Thanks.
