I have gotten rxTools to work on my 3ds, but I would like to update to Luma3ds with menuhacks so I can boot into luma right away. My only issue is I can't get my 3ds to boot into Dev or Pasta mode, to run the sysupdate. I've tried on 3.0 and the 2.56 or whatever the stable version is, and to no avail. Everytime I try to boot in pasta or dev mode it just hangs at a black screen.
