It is full, if you have the files BOOT0, BOOT1 and rawnand.binHello
Is it a complete nand Backup?
Can i restore it when i Update the Firmware? Or it has a Software brick?
What is with the RPMB Partition?
I Read that this Tool Dump all but what is with this Partition?
Thanks
Yes, it will be possible to restore it in the future.
But you won't be able to run it normally. The only way to run it, is to disable the fuse check with a CFW.
But it's nice to have. With atmosphere, you can use it with emunand for homebrew, cheats, hacks, etc.
And you can have the eMMC updated to the latest update for new games, eshop, online, etc.
