So a while back, einstein95 showed me a photo in which he had manually updated NVer and CVer in his system, prior to GW2.7's release, and showed a "9.3 emuNAND" to me. It was actually running 9.2, but had the NVer and CVer for 9.3, and the system didn't complain. However, he attempted to update his system (When 9.4 was released), and to both of our surprise, it didn't update at all! It actually failed to update! Today, I attempted the same thing on my emuNAND to see if I could prevent the 4.3 emuNAND from updating to 9.4 using Gateway's 2.7 launcher. However, it seems to have failed. My question, and goal, is to find the following: What can be installed, as to prevent the system from being updated? And, once that is accomplished, can we install this to a 4.X+ (In the event of Gateway releasing support for other firmwares soon) sysNAND, and prevent the sysNAND from being accidentally updated?
