Hacking Downgraded Switch FW, Won't boot up into stock or custom FW

[MaskedWarriah]

Recently I downgraded my Switch firmware, after doing so it wouldn't turn on. Tried booting it into RCM and it works. I tried to launch atmosphere (0.8.0) But it wouldnt boot up. After some tinkering it booted into stock firmware, I didnt know what I did. After a bit I tried it again, nothing. Can someone please help? (Not in Auto RCM)

what firmware are you in? if in 6.2 then just follow blahblah's instruction on the other thread. It worked for me.

I used to be in 6.2 Im now in 5.1

The way I did it was to update to 6.2 using the switch update(could be risky since you're connected to nintendo server). I then followed blahblah's direction by putting the patch files in the atmos folder along with hbl.nsp on the atmos folder as well. I then pushed the fusee primary bin to switch.

I cant even boot up into the switch firmware

Your fuse was burned from the OFW 6.2 update. That’s why your switch won’t boot up. You have to use CFW for your switch to boot now. You should be able to boot using Hekate then updating back to 6.2. If I’m wrong someone here will chime in.

Im downloading an old version of atmosphere to see if it will launch then hopefully that works

Just restore your NAND backup.

Just restore your NAND backup.

Hopefully you made a backup of your nand before downgrading. Or did you downgrade by using your nand backup of 5.1 and this is what left you in this predicament.

Backed up my 5.1 nand

Then you should be able to (if I’m not mistaken) boot into hekate. Then Boot OFW from launch menu. If your switch boots, then update back to 6.2 and Then use the new Atmo.

Doesn't boot up, doesnt get past the Nintendo screen using atmosphere either

Well hopefully someone with a little more knowledge can jump in and give you a hand.

What exactly was the steps you used to restore your nand?

What exactly did you do?

One thing I s

What exactly did you do?

Backed up my 5.1 nand, now my switch wont start

 

[linuxares]

But how did you restore your NAND? What version were you running? etc.

Restored your 5.1 backup over 6.2 with burnt fuses. Check fuse count should be 8 I believe.

You did restore both BOOT0/1 and rawnand correct?

Also if you didn’t have exfat drivers when you made your nand backup they won’t be there now and could be causing some issues. Wouldn’t hurt to try a different card formatted to Fat32, shouldn’t be the case but you never know.

I managed to make it to the home screen, but now it gives me an error

You aren't answering my questions.

Dont think this has anything to do with the backup
