Well...I followed the A9lh guide written by Plailect. However, when I got to section 3 step 6 and tried to update the firmware after installing A9lh and luma3ds CFW, I was unable to update it (the update only went halfway through and then the error occurred. Then according to the Plailect's guide, we should restore the original nand, which I did, which was 8.1.0 something. But since hourglass9 only gives you two options, I chose the restore nand (kept A9lh). However, after reboot, there were a few new tiles in BLACK, one of which was something called banner. Besides, I accidentally updated the emunand to firmware 11.0. Now the question is after I restore my original nand, is my 3ds still on CFW with luma3ds and A9lh? In addition, the Decrypt9 seems no longer work as well as the gateway or other browser exploits or hacks. Is there a way to completely restore my 3ds to original or factory setting with the original firmware? Or is there a way to use Decrypt9 or make is accessible again? I would like to get it fixed as soon as possible.
