I have installed cfw on 20+ 3ds systems now and this is the first time I've ever seen this issue and I cab find the answers to a few questions. 1) I down graded have all the required files but for some reason Te browser exploit to load the arm11.bin doesn't work. It glitches out the bottom screen... then stays there. For hours. So 1 is there a fix. 2) because the systems at 2.1.0-4u (o3ds system ) would upgrading it back to 11.2.0-35u cause a brick ? Considering I can't get into homebrew or arm9loader or hourglass I'm frustrated and been at this for 5 hours looking for answers please help.
