Stop. So much misinformation on the Temp today. Why is it that people are intent on helping even when they don't know what they're doing:
------------------------------------These 3 titles can be found in a regular old 3ds downgrade pack-------------------------------
0004009B00010602 - Non-Nintendo TLS Root-CA Certificates
0004013000001B02 -
GPIO
0004013000001A02 -
DSP
----------------------------------This one can be safely deleted carefully or ignored--------------------------------------------
0004003000009E02 - Cabinet (amiibo Settings)
Extended answer:
Any downgrader based on safesysdowngrader will always be wrong and not downgrade those 3 titles because it has a hardcoded downgrade title list (based on 104 titles only).
So, unless you manually add those 3 titles and rerun the downgrade using a downgrader that does not have these 'safe' features, it will always not downgrade them. This mostly affects systems that start at 10.5 or above.
Alternatively, you can downgrade those 3 titles using a Gateway in sysnand-patch mode using Devmenu2x (only, no other version). By simply installing them via Devmenu2x, it overwrites the correct tile with the one you want.
The amiibo settings can be deleted using the old FBI version, after previously launching minipasta (via HBL). Or leave it alone, because you're going right back to 10.7 or 11 anyways.
