Good news.
I finally waddled my way through the HexEditor and got the 2.22 core executable created. Now I just gotta wait for this current WU to finish, and I'll swap it out and fire the control center back up, and keep my fingers crossed.
Man, why can't they just let a guy download the executable.....
Two more questions ArVee, please
1) When I swap this out (yes, I have a folder to move the 2.25 core to for later use....) - is there anything I need to do in order to prevent the control center from auto updating back to the 2.25 core?
2) The current 2.25 core is named FahCore_15.exe. That tutorial stated to rename the 2.22 core as FahCore_15_2.22.exe. Is this going to matter, should it really also be FahCore_15.exe?
I guess I'll know soon enough!
