620

After long time waiting, gateway 3ds team finally released a Gateway 4.0B private
beta. This 4.0B private beta has added GW Time Machine app & A9LH Installer, but
no 10.3 sysnand support. As it is a private beta, but not the public beta. Gateway
3ds team still works hard on the feedback from beta testers and want to give card
users the the best, safest and user-friendliest program. There will be a public beta, i
guess. Please be careful to use the 4.0B private beta, and there should be still risk
of bricking.

If you want to use Gateway 4.0B private beta, please do backup 3DS NAND and has
one way to restore it. There is new page for Gateway 4.0B private beta and you can
lean it from its Private Beta Program
