I guess my confusion is that if I put gupdate.gcd in rgn_tools it says that there is only two sections boot.bin and fw_all.bin they are at the addresses you stated.
But you guys keep talking about all these other regions/sections that I don't see in RGN_Tools or any other programs I've used . I do understand that some of these region names
are arbitrary from my reading in this and other sites.

After reading your post I have to assume that gupdate.gcd v4.6 has only two sections boot.bin and fw_all.bin.

Sorry for being a pita but I do want to understand this. I am a firm believer in, if you give a man a fish he eats for a day but if you teach him how to fish he will never
go hungry. And I am hungry to learn this.
