Hacking Updated Firmware Black Screen NAND Issue

[bulgarypanda]

I updated my firmware to 8.0.1 using ChoiDujourNX (which I've done before for 7). I did a NAND dump beforehand, updated firmware, and booted back into SXOS (v2.5.3). I can book back into SXOS, but it won't boot into either CFW or OFW - all I get is a black screen (backlit, though, so still power). Additionally, somehow my NAND backup includes boot0 and boot1 but the full NAND dump is missing somehow? So I can't restore the NAND from the sxos folder I have. Am I screwed?

You need to update SX OS to the latest version.

Sxos is in 2.8.3 Beta now and that version have the suport to the new FWs,did u try update the files? And on ChoiDujuourNX did u use the ExFat option?(That I recommend to use)

I did use exfat. I'll try updating sxos to 2.8 and see if that works!

Possible ur sxos is too old,on every update,they have new supports,when a new FW is launched,the SXos Team update the files to suporte the new FW

Remember to always get the latest beta sx os before updating or check exfat if you got your exfat from choudujour.

So I updated to SXOS 2.8 and I can still get SXOS to load, but now I get black screen, no backlight when trying to load either CFW or OFW. I can get into the SXOS options and tinker so it's not bricked, but I can't get the FW to load either. Other ideas?

Sounds like you lost your exfat update from choudujour. Format to fat32 and put everything back.

I formatted to FAT32 and replaced the boot and license etc, but still just getting a black screen when trying to load either firmware. I also tried a second SD card but no luck there either

If it crashes when booting usually it means it can't read your card. What did you use to format your card to fat32?

Is autoRCM enabled?
Try disabling autoRCM and booting normally in OFW

If that still doesn't resolve your issue you should rebuild your NAND

I used my Mac's disk utility.

Yeah, I uninstalled autorcm. How would I go about rebuilding my NAND given that I don't have a full backup saved?

It just happened to me right now and i don't know what to do, i'm desperate did you manage to solve it?

-Edit- so, i was able to get into the sx os menu, and went to options, then i deinstalled my auto rcm thing, it booted to the N switch logo but was stuck there for a while, then i pressed the power button and it randomly booted normally, i have no clue of what happened. I was able to boot into the OFW and checked the FW ver. and it updated apparently, BUT my switch seems not to be charging and that's weird... AND i can't acccess to CFW i was only able to get into the OFW and that's all i don't know what to do.
