Hacking Problem for downgrade EmuNand 10.5 -> 9.0

[Asia81]

Hi,

I need to downgrade my emunand GW3D from 10.5 to 9.0 (N3DS), but when I install the whole folder of cia with DevMenu, it show me an error with:

Level: LEVEL_STATUS(-7)
Summary: SUMMARY_INVALID_ARGUMENT(7)
Module: MODULE_NN_AM(32)
Desc: DESCRIPTION_ALREADY_EXIST(102)

It's because the AM module doesn't let CIAs with lower versions overwrite existing ones. Use sysupdater's downgrade function! It removes the existing titles before installing.

Ok, let's see

if that fails you can always dump you title.db,import.db seeds.bin etc everything related to game data and settings/saves.

Then just clone your 9.0 sysnand to Emunand and before starting emunand inject all the files again.

It will do initial factory reset setup but them load directly into emunand with all your games and them theme you had set before.

Ok, SysUpdater using downgrad function is good.
But it's strange, it downgraded to 9.2, and I download a pack of CIA with firmware 9.0

C'mon can't you stand a version only different from what you wanted in Home Menu and NVer?

Gateway uses firmlaunch? if so, uses emunand's or sysnand's native_firm?

There's this thing about booting 10.5 with a 9.0 or 9.2 native_firm granting you access to arm9 on emunand and such. Don't quote on me right now, but I think so.
