hey i put the updatedsysnand file into the rei folder then when i turn it on it hangs on a black screen yet when i delete the file it will load. also you can use technical words ive been in the scene for a while P.S I have A9LH
do you know what to do my sysnand is fine its on 9.2 and my emunand is on 10.7.When you put the updatedsysnand file, AuReiNand loads Sysnand with firmware.bin (10.2 firmware in New3DS, 9.6 in Old3DS), when you load AuReiNand without updatedsysnand, it loads Emunand with firmware.bin. If it hangs at black screen when it loads with updatedsysnand it means that it cannot load sysnand properly.
if you're using emunand, you don't need to put updatedsysnand, updatedsysnand is only if you're using sysnand > 9.2 and you want to boot automatically to sysnand. If you want to use emunand just don't use the updatedsysnand file.
it will not load if updatedsysnand is on the my sd card but if its not on there everything will loadIf you want to swap sysnand with emunand you can use these guides:

https://gbatemp.net/threads/the-easy-way-to-swap-your-sysnand-and-emunand-a9lh-only.417072/
PS: Be careful, if you flash emunand backup directly on sysnand you will loose a9lh
Ok ThanksTry this: remove updatedsysnand and boot your 3DS whit L trigger pushed, it should load your 9.2 sysnand.
And as i said, if you want to swap emunand and sysnand to use your sysnand and get rid of emunand, you should use one of those guides.
