I'm trying to install this pokemon sun legit cia but I'm always getting this error "Failed to install CIA file." I'm using the latest version of FBI which is Ver. 2.4.12 and the FBI Ver. 2.4.2 which is injected in my health and safety app.
I have 6.2GB free on my sd card and I have Luma 8.1 and Homebrew CFW installed on my 3ds so what is the problem? I've installed this CIA from a community forum which has positive installation reviews so why? Please help me fix this problem!!

Do you know if there has been any issues with said cia before from others? If your trying this, have you looked into perhaps freeshop if that cia has issues with it?

I have also tried freeshop to install pokemon sun but it is too large of a file because it is 3GB and it may take a while to install and it fails to install because of poor wifi that is why I'm trying to install this CIA which I installed from MEGA which is more faster and no fails but the problem is that FBI fails to install it.

It's corrupted. Use FunKeyCia or Wii U USB Helper to make a proper CIA since you don't want to use freeShop.
