    As the title suggests, i was trying to make a system downgrade for an O3DS XL i had lying around. Having done at least 3 previous succesful downgrades before, i grew confident. However, 10.7 didn't allow Decrypt9 to proceed and do a NAND backup, resulting in having to do downgrade first, then a NAND backup.

    The first time, sysupdater marked an error, with one of the .cia files of the the update (weird, as i used those same files for the Previous 3 O3DS; valid region and all), and ended with a frankenfirmware 9.2, but still allowed me to enter HBL with Cubic Ninja, using 10.7 entrypoints.

    I thought that the issue could be a slow SD card, so i changed it with another one, formatted just in case, but to no avail. The second time tried to run sysupdater, it patched several files, but this time, it took longer before prompting an error, and when i tried to press B to quit and reset the system, the screens now go only black. Tried the forced update method to see if i had a little more of chance to achieve something, but it didn't work.
    My guess is that since it couldn't patch all the .cias, it may have bricked the nand. Unfortunately, i couldn't get a backup of it, as i was ACTUALLY downgrading to get Decrypt9 working.
    I'm really surprised, as i used the same tools and files to downgrade 3 previous O3DSes. Don't know what exactly happened to cause the error.

    My question is, is there any way that i could salvage this console and unbrick it? I can Hard mod it without any troubles, but i'm worried since i do not have a nand backup to reflash to this console. Would just a reflashing of the same incomplete nand.img help me? Or could i inject the remaining .cias files to such image and then flash it back to the console? if so, how?

    I apologize beforehand if this has been posted before, but i haven't found an explicit answer to that skimming through a lot of threads right now.

    Probably a stupid question, but have you tried using the recovery menu using L+R+Up+A on boot? If you have and you still cannot access the system, then I would say it's impossible for you to recover the 3DS.

    Sorry to say, but if u cant boot neither on sysnand or system recovery and doesnt have a valid backup then u are for sure bricked beyond help.

    U can send it to nintendo for repair though.
