Thank you all for your help! I extracted both the Sys-Patch and Sys-Patch 1.5.1 (Both together on the current release of sys-patch on the linked Russian website) to the Root of the SD Card and now was able to install the XCI file using Awoo Installer!You're probably already fully set up for Hekate's FSS0 method. If you didn't modify the file hekate_ipl.ini that came with your sigpatches, you just need to select the leftmost option in Hekate's main menu (Launch), and then select the CFW you want to launch (Sysmmc or emummc, depending what you have). If you also use sys-patch and the modified fusee.bin, you'd have 3 different options to launch Atmosphere with sigpatches. You should be ok.
I truly appreciate all your support and hard work helping users like me! Thank you very much and have a great day
