run safea9lhinstaller from homebrew launcher and reinstall a9lh using plailect's guide steps
use the homebrew launcher to run safea9lhinstaller, and follow the steps regarding safea9lhinstaller
Well there aren't many choices. If it's got mini CFW then it's probably shadowNAND. If you check the GitHub page here, you'll see that ShadowNAND boots /homebrew/3ds/boot.bin. So perhaps you need to put the safea9lhinstaller payload there.
If you can't "access installed cias", that means you don't actually have a mini CFW in NAND; you upgraded while using a CFW that doesn't have FIRM protection.
no no it was the payload that boot without sd card, but my 3ds was working perfect about 3 months now
Yes, and ShadowNAND is one of those payloads which boots without SD card. So you need to try putting the a9lh payload in the location where ShadowNAND expects it to be.
I thought you said you didn't know which payload it was? Well, if you're really using that payload then /arm9loaderhax.bin should work. If it doesn't boot that, then something is wrong with your A9LH in NAND. Or there's a fault with your SD card.
What happened before the freak out? Did you update anything? run anything new? add/delete anything to the sd card? any errors or problems occur around the same time? Or was it just running smoothly, you turned it off normally, then when you turned it on next, your stuff didn't work?
