I'm trying to update my son's 3DS. He bought it a few years ago from someone that had hacked the device. For years he was able to download games using FreeShop. I get why the application isn't working anymore so it doesn't need any extra explanation. I would love to know how I can update the 3DS to the latest (hacked) firmware and what application we need to use now to play back-ups. I prefer real back-ups (since I own a lot original 3DS games). Is there a guide on how to install the latest firmware and homebrew on a legacy hacked 3DS?
