I have a Gateway and I'm with some questions about the new update. My Sysnand is in version 4.2 I can install A9LH without performing the upgrade process to 10.x If I need to format my SD completely I will leave my 3ds Brick. If Question 2 can not be performed in the manner which I am accustomed to how the formatting of the 3ds is done with installed A9LH. I own an old 3ds xl after performing the A9LH installation process as is done updating the FW. I thank you who can help me.
