So I did a ctr transfer and it just greeted me with a black screen??.... So uh? Not sure what I did wrong tbh.https://3ds.hacks.guide/ctrtransfer.html
There use to a 11.4 one , but Plailect removed it, in the link above is 11.5, and the one I link earlier is 9.2, you don't need to go to 2.1 for this, anyway you would be back to where you are currently if the transfer goes through and you still can't update.

Yea black screen on boot. Not booting....Try a ctrtransfer I guess.
