Update: Since Atmosphere has released with 7.0.X support, To downgrade without a backup, just use ChoidujourNX.
For those with backups you can still follow the method below

---

After seeing reports of downgrading back to 6.2 been broken after updating to switch firmware version 7.0, I can confirm these to be false. I successfully downgraded my switch with 9 burnt fuses on 7.0 to 6.2 with 9 burnt fuses

Downgrading to 6.2 is possible and not broken. Both boot0/boot1 must be the same version as nand backup

• Step 1) Place 6.2 nand + boot0/1 backup on sd card
• Step 2) Boot into RCM and launch hekate
• Step 3) Restore boot 0/1
• Step 4) Restore GPP Partitions (or rawnand, I personally used GPP Partitions)
• Step 5) Launch CFW using Hekate 4.6 or ReiNX 2.0 or sxos (haven't tested with fusee-primary)
• Step 6) ????
• Step 7) Profit

EDIT: This is for FG consoles not ipatched
EDIT 2: You will loose any saves you don't have backed up

Will upload proof if people desperately wish

what's the difference between restoring GPP partitions or Rawnand? I have backup'd both.

Also you said: "EDIT 2: You will loose any saves you don't have backed up", why is that?

Partitions takes up less space afaik

Because you are restoring nand anything added to it since the backup (or clean restore without been backed up) will be deleted

even when restoring the rawnand?

 

[Adran_Marit]

even when restoring the rawnand?

yes, because they the backup was done before more saves were added/updated, so you need to back them up before restoring or you loose them

Oh yeah i get it now... Fastest way to do so? I don't wanna re-backup my rawnand, takes too long.

if you're on 7.0 you will need to connect your switch via HacDiskMount, backup the saves as directed in the manual choi downgrade guide

No i'm not on 7.0 yet. I'd like to update to 7.0 from 6.2 using Choi (don't wanna burn fuses) to play online, and go back to 6.2 if needed.

Oh okay, in that case, if you're already using CFW then use checkpoint to back all your saves up

also make a nand and boot0/1 backups

Already backup'd rawnand boot0/1 some weeks ago (6.2 of course)
i'll just use checkpoint then. Thank you

 

[AngeloftheNight091]

I mean where they both for the same firmware version?

yes 6.2.0

 

[Adran_Marit]

yes 6.2.0

And you've hard power cycled?

 

[huma_dawii]

Can I downgrade without a backup, what if I have an EmuNAND with SX OS that's 6.2?

 

[AngeloftheNight091]

And you've hard power cycled?

oh, after the downgrade , i can only rcm? I cant go back into ofw?

 

[Adran_Marit]

Of course you can't get to OFW... in RCM you should be able to launch CFW thought

 

[AngeloftheNight091]

Yea, I got that to work. I just assumed ofw would work like 3DS used to. Sorry for the confusion. Thanks for the tutorial

How can it run 6.2 with 9 fuses burnt? Shouldn't it not boot if the number of fuses is > 8?

you're using hekate to boot CFW, I didn't say stock would work

 

[MHHuk]

Is there any way to manually split my nand backup so I can fit the backup I did on exfat on my current fat32 sd?

when restoring an ex-fat card is required... so backup your current sd card if it's the only one you have

hekate bypasses the fuse count check, so cfw will always work
