Today I tried to upgrade from A9LH to B9S, so I followed the 3ds.guide tutorial on that and at the end of section II my device is supposed to reboot, however, if it didn't I had to make sure that I copied boot.firm to my sd card, when I popped my sd into my computer I saw it there, tried copying again and nothing, it still wouldn't turn on, I tried redownloading the .7z file that contains it, copied it again, nothing, it still won't turn on.
I have an old 3ds with A9LH, I think it is know B9S as I completed the part where it was installed, I had Luma 7.0.1 before upgrading and added Luma 8.1.7's boot.firm for this tutorial, that's the file that should be the cause of the problem but it isn't as it is in my sd card and on the right directory. I was able to follow up the guide until step 5 of section II, where it should reboot but it doesn't, thanks in advance.
