My 3ds xl crashes when I open any homebrew applications with the wavy blue intro. Is there a fix for this?
chkdsk X: /r
(X = driveletter). You might try again now or additionally move everything from the SDCard to PC and run on the empty SDCard a check with h2testw (write and verify option) to be really sure the Card is not corrupted or counterfeit.Actually don't do any of this. Send a screenshot of your error so we can properly tell what's wrong. (Could be a corrupted SD and installing more stuff may make it worse.)The blue wavy is the homebrew launcher, your main application to run homebrew stuff. Be sure you use latest Luma version as the homebrew launcher comes with and use latest Homebrew launcher loader (Channel).
Or install and use the Unistore to get any homebrew and those uptodate.
Did you check the sdcard though?3ds now works after formatting, it was corrupted.
