Okay, so I followed this guide and I thought I did everything correctly, but HANS thinks the romfs file I created was invalid. I tried just renaming the non-patched romfs.bin to (Title ID).romfs, but HANS recognised that as invalid too, wtf? These are the steps I've taken: 1.Download the update (1.2) CIA off that iso site. 2.Decrypted the CIA using Decrypt9 on my secondary 3DS (the one that has emunand, but not my NNID) 3.Extracted the romfs.bin and exefs.bin from the decrypted CIA using this command in ctrtool: ctrtool -p --content=c (cia).cia ctrtool -p --exheader=exheader.bin --exefs=exefs.bin --romfs=romfs.bin c.0000.00000000 4.Extracted the romfs and exefs contents using the following commands: ctrtool --intype=romfs --romfsdir=romfsdir romfs.bin ctrtool --intype=exefs --exefsdir=exefsdir --decompresscode exefs.bin 5.Used braindump on my main 3DS to dump the CXI of Pokemon Bank. 6.Extracted the romfs from the CXI using the following command in ctrtool: ctrtool -p --exefs=exefs.bin --romfs=romfs.bin (cxi).cxi 7.Extracted the romfs contents using this command: ctrtool --intype=romfs --romfsdir=romfsdir romfs.bin 8.Pasted the contents of the romfs from the update into the contents of the Pokemon Bank romfs. 9.Used RomFS Builder to rebuild the patched romfs. 10.Renamed the code.bin from the update to (TitleID).code and put it in the hans folder on my SD card. 11.Renamed the romfs to (TitleID).romfs and put it in the hans folder on my SD card. Is there anything wrong with what I'm doing? I need to get this done asap before everything on my Pokemon Bank is deleted.
