didn't work
in the words of Johnny 5, "Need More Input!" cant exactly help if we dont know how you migrate dto B9S, what your previous setup was, did you move from Emunand to Sysnand. are you sticking to emunand . any modified twl bits (loading a patched twlbg.cxi etc) do you get an error. do you stick at a whitescreen? does the 3DS just immediately Shut off? be descriptive of everything you can recall you've done since you did Any modifications that go near twl before we can Diagnose your problem find out why TWL Functionality is busted and how to repair it in teh course if it can w/o a complete nandtransfeer or whatever teh case maybe.didn't work
So I managed to fix it by updating lumaI also have this problem,and just now tried the guide thing.TWLoader is still crashing back to home menu with no error after crashing.When i go to open anything else like a digital title,app or physical cart it then hangs on 3ds logo.
Edit:I assume OP has this same issue...
