New 3DS original firmware: US
My steps:
Downgrade emunand to 9.2U
Download Japanese old 3DS updates 4.2, 4.5, 5.0
Download new 3DS update 9.2
Merge all the CIAs, replacing old ones with new versions
Delete update CIAs beginning with 0004001B, 0004800F, 00048005, 00040130, 00040138, 00048005.
Delete NAND apps
Use SysUpdater to install the Japanese CIAs
Inject SecureInfo_A
....
The problem is, about 6 CIAs install. I have about 70 in my folder.
I have my emunand backup. Installing via DevMenu manually brings up a invalid CIA error even after multiple redownloads, and using the update firmware option immediately errors out.
I don't know what to do.
