devmenu/bbm says : cia already installed, annulling import... or something like that.
because i want to test safesysupdater.
Testing safesysupdater on EMUNAND is pointless since the firmlaunch makes 10.4 EMUNAND different from 10.4 SYSNAND.

memchunkhax2 definitely won't work on 10.4 SYSNAND, while firmlaunch may get it to work on 10.4 (safesysupdater use memchunkhax2)

testing safesysupdater on 10.3 EmuNAND will tell you nothing as EmuNAND can be up and downgraded via the regular sysupdater as EmuNAND runs in CFW. Only way to test it properly is on a 10.3 sysNAND console running it on sysNAND.

We already give you the answer how to downgrade form 10.4 to 10.3

I don't get how you can't use dev menu/ big blue menu to install 10.3 firmware cia (downgrading). There is something wrong with your EMUNAND. Are you using the cia version of FBI/DEV menu/ Bigblue menu?

What the error code? Are you using the cia version of those cia managers? Sound weird as eck.
no error code, thay just say FOR EVERY UPDATE CIA that the cia lready esist and the do not install it.

Hey, I'm trying to do the same, downgrade my emunand 10.5 to 10.4 or 10.3. The reason is that I'm having an error in FBI, FBI (cia), BBM, Devmenu every single one are giving me an erro when installing some .cia games, the games have more than 1.5 bg (I have the error with, kingdom hearts, shingeki no kyojin, and ff rythm) the error says invalid cia and I've tried almost 3 times in every one to make sure that is not coincidence. So the problem is, I'm not finding the cia files to downgrade to 10.4 or 10.3. Can anyone give me a link or an tip on how to search? Thanks a lot

    I don't like popcorn at all; bland taste, and it got ruined for me because of high school - the school cafeteria reeked of microwave popcorn for several days...utterly revolting, couldn't even enter the place it stunk so bad.
  • RichardTheKing @ RichardTheKing:
    Nah, for movies I'd rather get a bag of lollies instead of popcorn.

    lollypops? a whole bag?

    Not lollipops; what Americans would call "candies" or just "candy" IDK. Before the pandemic, cinemas used to have buckets of different ones - sour cola, sour watermelon, and many others; I used to get a scoopful of two or three types into a paper bag to have throughout the movie.
