Well no you need boot0 to complete your full NAND backup unless the firmware you are currently running is the same as the NAND backup you are restoring. If they do differ, you can either temporarily downgrade to 4.1 with ChoiDujourNX so you can dump boot0 (preferably without AutoRCM enabled) or build a boot0 of 4.1 with ChoiDujour.

I think downgrading to 4.1.0 with Choi is easiest at this point? I just downloaded it so I'm probably going to that route. And then once that's installed I'm just going to boot Hekate and dump Boot0? Since I already have boot1 and my rawnand I'm good on that front?

Thanks for all of your help!

Yeah just make sure you disable AutoRCM when downgrading with ChoiDujourNX or else the boot0 you dump will have AutoRCM pre-enabled which may or may not mess you up if you aren't keeping track.

Will do, I will do this now and report back when I am done.

Fatal error <1> when writing to SD card for boot0.... not sure why?

Edit: Just kept trying it and finally got it to backup.. Likely why I didn't have boot0 in the first place lol

Finished at about 1:00 AM last night so it was time for bed lol. Everything seems to have went okay and I am not on 6.2 OFW with my restored nand and I did a factory reset and took the sd card out before booting just in case as well.

Thanks again for all of the help!
