Switch 7.0 Downgrade to 6.2 tutorial

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

Probably for the best :) Also if you don't have a backup I suggest doing one

I do have a backup that I made when as was on 4.1, but I was wondering, if one day I would like to downgrade back to 4.1, could I use my backup as it was made before autoRCM was enabled? I would assume it would boot straight to OFW and possibly cause problems?

yeah it won't boot if the fusecount is mismatched, like if the fuses are lower it's fine but if its higher you would need to boot using hekate stock then upgrade officially

Well fuse count would be mismatched, he wouldn't be able to boot into OFW, reason it work because he is booting into CFW like Rei NX.

I updated my Switch in error yesterday, it was forced with a Digital game update and I just started with CFW.

Had a full NAND backup with SX OS at 6.2 and restored but unable to boot now, any advice for a newbie on how to resolve please ?

I have just tried this process and now I cannot boot into RCM, restored both Full NAND and Boot 0/1 6.2. My switch will not turn on to OFW or RCM to launch Hekate 4.6. Any suggestions?

UPDATE: The tablet was actually on and didn't realized it since it now shows a blank screen on OFW, held power button for about 15 seconds and tried RCM again and it worked, all good here!

Try using hekate to chainboot sxos if you can still get into RCM

Can people STOP updating to 7.0 and wait for CFW instead?
Click to expand...

Yeah it's a rule but newbies to the scene might not know. Don't update until new cfw is out people

I updated for testing purposes of downgrading and other reasons :P

    @Xdqwerty there is health behaviour you can add to your character, then to use a health bar is lil more complicated, google n watch a few tutorial video on it, be too hard to explain here.
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, the character has the health behavior
  • BigOnYa @ BigOnYa:
    I know you have to create a health and health max variable. Then there is a calculation you use in code to subtract width size of the health bar. Google few vids.
  • BigOnYa @ BigOnYa:
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, the "greenflatbar" is one of the preset health bars btw
  • BigOnYa @ BigOnYa:
    Yea you can use any bar/sprite. It will just change the width. Ok good luck and have fun. I'm off to go shoot some pool at the bar. Talk to you later.
