None of the hacking guides seem to mention how to do this, all of them talk about how to fully hack the Switch to install CFW or loaders/homebrew, which I don't want to do. I just want to dump a backup of all my my Switch's internal keys, contents, etc without modifying it in any way.
Thankfully I have a lunch-era Switch which is susceptible to Fusee, even if it's on the latest firmware (from my understanding no firmware can patch this and even on the latest it will work, right?). First of all, is there any difference in which jig I get? I see a few different designs on eBay/Aliexpress. Is there a specific one to try to go for? I heard some claims that there were some shoddy jigs that shorted out the Switch, but I have no idea if that is true.
And then, what would I have to do if I just want to dump all of my Switch's contents while trying to leave no trace of any modifications? I heard that just simply booting into the recovery mode that the jig lets you access apparently sets some kind of flag? Is there any way to re--set that flag? Are there any other known traces it leaves behind that you can't cover? I know there is no way to 100% know every secret Nintendo put on the Switch to detect hacks and there is no 100% way to guarantee you can't get banned, but if I can reduce my chances to 99.99% and use methods that so far nobody has gotten banned for I would like to go that route.
So what would be the best way to use a jig/fusee exploit purely for the sake of dumping all of my internal keys and backup all of my contents without touching or modifying anything? Are there any guides or videos to do specifically this and not hack it all the way or modify anything? Or if not, can anyone explain how to do something like this? Do I also have to do anything to set it back to stock/reset that flag after I am done dumping the backup with the fusee/jig method? Also, I assume this backup will be encrypted right? Are there any tools on PC that can decrypt it if I also dump my keys or do I have to use the Switch to dump an unencrypted version? Since I would also like to load up my save files into Yuzu/Ryujinx, I am assuming I can't just load my NAND backup into the emulator like you can with Dolphin, but if the backup is decrypted I can at least manually pull the save files out of it and put them in the emulator.
