Hello. After I saw this many of bad turtorials, I decided to help you on doing a downgrade without a nand backup.
Let's begin. Make sure you have enabled autorcm on hekate https://github.com/CTCaer/hekate/releases and have a Nand backup. I am not responsible for bricks.
First step make a folder on your sd named "FW"
Second step I don't know if it's against the rules to give you fw files from here, better safe than sorry! Anyway, google "Switch firmware files" and you should find a link
Third step download 6.2 and unzip it on the fw folder we made
Fourth step if you don't use atmosphere we will need to use it to get to choidujournx, put the files on your sd card https://github.com/Atmosphere-NX/Atmosphere/releases
You can use external payload with SX pro and gear by putting the atmosphere payload on the root of sd and injecting it through the menu of sx. press vol+ while booting sx and click options then external payload, then atmosphere's payload. Don't do this now since we haven't put choidujournx on the sd yet.
Fifth step make sure you have choidujournx on your switch folder https://switchtools.sshnuke.net/
Sixth step boot on atmosphere (for sx pro and gear users launch now your external payload) and open choidujournx on the hbmenu
Seventh step choose the fw folder and click select all. It will start reading the files
Eighth step it will ask you if you want exfat 6.20 or 6.20. choose exfat
Ninth Click system initialize (WARNING All games saves and stuff will be gone once we do this) If we don't do this, brick chances hit the roof!
Tenth start installation
Eleventh click reboot once it's done.
twelfth click reboot now
Thirteenth, inject your old payload and start the setup.
Good luck!
It means a lot to me if you like my post!
Ask me any questions and if I can, I'll answer!

BACKUP IS ALWAYS NEEDED..
Dont play the brick lottery, Proper way proper guide no...
You lose power whilst choidujournx is running or writing updates,
then you wont recover back into homebrew to run choidujourNX,
And without a backup, your have to rebuild your nand with choidujour.exe AND hacdiskmount
ALWAYS BACKUP FIRST OR HAVE A BACKUP PREVIOUS Period.

Always.

 

[DeoNaught]

Always.

You should Say that you should always make nand back up in the OP, people are going to try this, and Brick their switches, and they won't have a Nand back up because you said they didn't need one. Things can go wrong even if you follow instructions to a T, That's why you always make a back up

because people might backup nands and restore them because they have lower fw. It is a rule of thumb to have a nand.. It's just not needed for the procedure

i gotta ask, why is everyone so interested in downgrading to 6.2, i mean... I'm on 6.2 and I'm thinking about updating to play latest games...

should I or..?

Guy do you not see the point ?

Add backup your nand to the begining of your guide, that not backing up or having a backup before following (your)guide may result in a brick and the (end user) does this at there own risk

For example lockpick can't deceypt all keys.. And some apps crash, but hobeshon they are not much.

I believe lock pick was updated to support 7 now. if i remember shchmue said.

Yes but it has a bold warning that you need to use lockpick rcm to get all keyz

and I just hit the milestone of 100 messages. I think now my turtorial is more accurate.

UPGRADE NO

Pretty sure on this,

you could.ignore fw version on install

 

[Canna]

My response was to @LapCheong

My response was to @LapCheong

ik, useless to upgrade some homebrew dont work.. for example lockpick needs rcm

Lets clear this up for everyone

No need to initialize if your upgrading,
Helps to initialize when downgrading to prevent issues.

To which pohaxsf Said

So Lapcheong
you do not need to update to 7.0.1 to play HOB
you can use a program called goldleaf and or tinfoil..

Gold leaf when installing NSP files can install the game so it skips the System version check allowing you to play the game on lower system version...

That doesnt work, i tried ignoring the firmware version and wasn't able to install.
The error i gotten is :

0x236e02

Module: FS (2)

Description: invalid PFS0 (NSP) (4535)

Going to double check to see if the NSP is okay.
Will update

Use lithium, and if continues, you have bad nsp

Use lithium and it even say it cannot be installed and the next message was that it needed higher firmware.Masterkey 8
