    I got my switch about 6 weeks ago on firmware 3.01 and installed RajNX first thing I did was a nand/boot backup

    I then officially updated to 5.1 - I will be honest here I could not get my head around updating via Chour and the exfat stuff

    I am pretty sure I have burnt 3 or 4 fuses

    Does that mean my backup was wasted?

    And yes I know I am a tard

    Yes, if you restore your backup, you won't be able to boot the console without bypassing the fuses with another bootloader such as Hekate. Best make another NAND backup.

    You can't downgrade for any potential warmboot or coldboot CFW, but you can still use CFW through Fusee Gelee. Your backup is more or less useless, unfortunately. The only use for it would be as a last resort if your NAND gets borked, then you can flash it and then reboot with Fusee Gelee and update again so you're on the right fuse number.

    There is a chance of a warm boot exploit in the future.. key word CHANCE..

    undo AutoRCM, backup, then redo AutoRCM & only update via ChuiNX (whatever it's called) on the switch

    It will be a clean backup... But not a Untouched backup..

    But if you made a 3.0.1 virgin (untouched) backup , which you said you did cause you backed up before any modification
    you can use that to make a virgin (untouched) nand 5.0.1 with hacdiskmount and choidujour. pc version and you can restore that to your console, it will be untouched and will work on your current fuse count without the need for hekate or a bootloader to bypass fuse check
    So the 3.0.1 is still very useful...

    Or like OkazakiTheOtaku said, you can restore the 3.0.1 with hekate, then launch stock with hekate , then update to 5.1.. then make a backup,, I like to remove auto rcm before any backup myself.

    Here is a backup guide if you need it

    his backup is not useless.

    You're fine. Unless you really care about the warmboot exploit. I don't think it's worth all the hassle when the current exploit is so trivial to do. Why boot into the OS and then have to perform a webkit exploit when you can just boot directly into CFW with the Tegra bootROM exploit? The only advantage of the future warmboot exploit is not needing an external device to push a payload. I understand it's good to have options but why wait on lower FW or upgrade and later have to restore said lower firmware? Then you'd still have to fuck around with emuNAND if you wanted to play the latest games. That negates the awesomeness of this unpatchable exploit. The fact that you can stay on the latest FW version.

    Updating was the right move if you just want to play games and use Homebrew.

    That's true. It's very easy exploit to do. Further more, preventing fuse update with fusee gelee with autorcm have soft brick risk. And officially updating firmware is better and more stable (just my feeling).
