Hacking Risks When Backing Up NAND?

[mranonymous]

Hello:

With the advice of this forum I've learned that I'm playing with fire if I don't do a NAND backup. I'm a little nervous though for some reason. Everything is working beautifully with SX OS, and I've yet to boot into Hetake. While I do know exactly how to back up the NAND (and realize how simple it is), I am still very nervous for some reason. Hell - I get nervous just booting into SX OS.

Before I proceed, are there any chances of a brick, or any other risks that can occur when booting into Hetake and backing up my NAND? Or am I just a little bitch?

You're just reading data. No risks

There's virtually no risk, and it's highly recommended that you make a NAND backup before doing anything else. At the very least, backup your BOOT0, BOOT1, and eMMC SYS.

Perfect, thanks for the quick reply

Will do, thanks for the info!

You can also backup your eMMC USER, but that's just going to be your games, saves, and other user settings. It's not necessary for brick recovery. Many people don't back it up because it's so big, regardless of how many games you have installed. However, if you don't have a lot of games installed, you can always compress the file to make it smaller.

Backing up your rawnand.bin is just a combination of the eMMC SYS and the eMMC USER.

Gotcha, thanks. Yeah I'm going to nix the USER backup, as I'm keeping all of the NSP files of my games on an external HD anyway. Question - is there a way to manually backup only save data from an SD card? Or is the save file combined into the NSP?

You should use Checkpoint to regularly backup decrypted versions of your important save files.

You should use Checkpoint to regularly backup decrypted versions of your important save files. Decrypted save files are also largely interchangeable between systems, just in case.

Oh great, thanks. I've seen that floating around but never looked into it. Good to know
