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

i have a dumb question is it possible to use a nand backup that is not your own?

Nope. Needs to be your own

 

[KirbyIndie]

Nope. Needs to be your own

okay thank you

 

[Adran_Marit]

okay thank you

If you don't have one then you need to use the old choi method of downgrading

Hi all! I did a wrong thing. I made a backup nand. But my nand files isn’t enough 15 files. It’s means i have had a “boot 0/1” and “useless nand”. I ran restore boot 0/1. I couldnt run nand restore. It make my NS is bricked. Have any solution for my case?

so i found this guide on homebrewguide on how to downgrade to you think it will work or should i wait until cfw comes out

It depends on how confident you are and if you read and follow the instructions properly, if you don't think you can then don't do it cause it can brick properly

What files do you have? if you have rawnand.bin.00 .bin.01 etc you need to join them

I joined the nand files by combinerScript.sh. I will send you director structrure I had.

yeah that doesn't look right... you should have atleast 15 of the files for a size of 29gb..

So. Is my NS is bricked, right? Could you give me some solution for my case? I ran Boot 0/1. and Couldn't restore nand file for my NS.

what firmware is it for?

Also how confident are you at following instructions and your ability to manually downgrade?

 

[Hieuphq]

I remember the version I run backup is < version 6.2
I'm developer, I thinks I can follow instructions to manually downgrade. Give me the resources or keywords please.

Good Luck. I'm not responsible if you brick your console

Interesting to know that it can be done. Thanks for the info.

This proves that no one reads the changelogs
Hekate fixed sleep mode like 10 years ago

I have the Boot 0 and 1 files in back up folder of my SD card but they can't be found. Do I need to put them in another folder?

remove the .bin from them if they have it

 

[AvatarMew]

They don't have a .bin.

This is what the folder looks like:

 

[Adran_Marit]

They don't have a .bin.

This is what the folder looks like:

add .bin to them then and try again?

That didn't work either, they were not found.
