Hacking How to backup NAND

[Peanut42]

Hi

Well, I think I made a big mistake. I followed the guide from http://switch.homebrew.guide/ and I upgraded to 8.1.0 firmware using ChoiDujourNX. As written in other thread, I can't boot into Atmosphere. Well, actually, I correctly send the fusee-primary from Atmosphere, and it boots, (the two splash screens and then the switch OS) and after a few seconds, it crashes with the "error code 2168-0002".

I think my mistake was upgrade to the "lastest" firmware. My switch comes with 4.1.0 and the fuses burnt are still 5 (protected with auto-rcm). I do have a full nand backup and boot0/boot1.

It is safe to directly restore boot0/boot1 and nand to "downgrade" and restore the switch? Or should I continue with the 8.1.0 firmware?

Thanks for the advise, but this is somehow frustrating because the firmware boots but crashes after a few seconds.

Hi have you try to formate SD card to your according format like fat or exfat before you update to 8.1?. Try to formate SD card and copy the new ATM from github and try again.

Actually, I formated the SD card, re-downloaded Atmosphere, sent fusee-primary from RCM mode and now it works.

Awesome.
