Note that while latest is usually greatest, if you MUST use 11.0 FIRMs, please enable at minimum the loader replacement, and if you plan on running Retroarch/HBMenu svcBackdoor as well. Nintendo broke quite a bit. It was quite literally a anti-hack update. Loader alleviates the ASLR issue, and many homebrew applications require svcBackdoor currently.
