Hacking Question Restored NAND through Hekate and now it won’t boot

[seri-kun]

My Switch is originally on firmware 5.1.0, and using SX OS and ChoiDujoirNX, I installed firmware 6.0.0 with exFat.

I restored my NAND backup (made using hekate, before I did any modifications) but after that, it won’t load either OFW or CFW. OFW, I’m stuck with a black screen. And CFW, a blue screen.

Checking the fuses info through hekate (Switch still goes into RCM/SX Menu, and I can load hekate without a problem), it says I’ve burnt 7 fuses — and iirc, 5.1.0 should only have 6 burnt fuses.

Is there any way to fix this, other than replacing the Switch/buying a new one? I don’t think sending this to Nintendo would help either? They’d send it back since it is tampered (tho it is still under warranty).

Did you restore the boot0/boot1 along with the rawnand.bin or just the rawnand.bin?

I don’t think so
I can’t find them on my computer, so I assume I accidentally skipped backing them up.

How did you update to 6.0.0? Did you use a special non-fuse-burning method?

I download the NX Firmware for 6.0.0 and used ChoiDujoirNX to install it.

Boot0/boot1 are firmware specific like your rawnand meaning you didn't actually fully restore your NAND (your boot0/boot1 are still from firmware 6.0 which explains the burnt fuse). Rebuild and restore them with this tool if you cannot load CFW onto your console: https://gbatemp.net/threads/how-to-...nofficially-without-burning-any-fuses.507461/

Oh, thank you. I’ll check this out in the morning (it’s currently 2AM in my time zone).
