I followed plailect's guide and successfully made it to the end of installing a9lh on an old 3DS XL. Everything seemed to be working fine, however, when I went to open the 3DS (I think to awaken from sleep but it may have been fully turned off), I cannot get it to turn on at all. I tried pressing the power button and holding the power button, both with and without the SD card inserted, and I can't get any response from the 3DS. The only thing that happens at all is the orange charge light comes on for about 5 seconds upon pressing the power button, but only if the system is plugged in to the charger. Any help? I really hope it didn't somehow brick, and even if it did I don't understand how since it seemed to be working perfectly after installing the cfw, then just stopped working without anything changing. Thanks.
