I just updated my homebrewed 3DS this morning without thinking, because I wanted to buy some of the games on sale on the e-shop. However, the 3DS will not not boot up and shows me the Arm11 error, saying “An exception occurred”. I’ve watched some tutorials online, and supposedly updating the Luma version to 10.2.1 fixes it. However, I’ve copied over the files onto the SD card and the error is still showing up. Since the tutorial is about a year old, I’m wondering if maybe this fix is outdated and if there’s a new solution, or if I’m just not doing it properly. Any help would be appreciated because I don’t want to have bricked my 3DS!
