Hello, I'm an o3ds user with rxTools installed. I recently followed these threads (https://gbatemp.net/threads/tutorial-patch-twl_firm-to-play-normally-blocked-ds-games.414578/, https://gbatemp.net/threads/r4-stage2-twl-flashcart-launcher-and-perhaps-other-cards-soon™.416434/) to to run my R4DS cart on my 3DS. But after I installed those two cias on my sysnand NAND, when I restarted my 3DS I can't launch rxmenu either with mset or browserhax. And stupidly, I ignored the first thread's recommendation to backup the sysnand, and I've lost my only sysnand backup, which I made when installing rxTools. So now I'm simply stuck, not being able to launch FBI, not being able to clean up the mess I've done. Is there any way to get out of this?
