I understand you, I'll try to post it more clearly for other people to understand, as I have the same issue.
The problem is, we can spoof the eshop and access it from the homebrew menu, we can also use HANS with FW spoof perfectly fine.
The problem is, some games like Fire Emblem: Awakening, or Shin Megami Tensei IV, these games do not use the eshop for their DLC, rather, they have their very own game specific ingame eshop.
This ingame eshop is the only way to buy the DLCs for this game, but the problem is, even with HANS, we are being told to update our FW to the latest version, and as such we are unable to purchase DLC for these types of games.
