I am just wondering if i need a specific type of 3ds or any 3ds will do for the subject matter?
3DS, 3DSXL. 2DS, New 3DS and New 3DS XL will work as work as long as the firmware is 11.3 or lower.
That’s sounds a little confusing how do i confirm that the firmware is 11.3 or lower before making a purchase?
Most retail units are on firmware 11.3 or below, as 11.4 just came out. However, if you want to get A9LH/CFW, you’re going to want to get a unit on 11.2 or below. If you’re buying from eBay, simply ask the seller for confirmation. If you’re buying retail, you will have to take a leap of faith, or google if there are any indicators.
Recently smealum released an 11.3 kernel exploit and safehax got updated with 11.3 support which theoretically makes installing A9LH and CFW on 11.3 possible.
