Hacking Could use some expertise with Nintendo Switch... This one is a doozie lol

[spank2610]

Ok here goes,
I purchased a switch online with original 5.1.0 firmware so i could hack it. Well I backed up the nand (or so I thought). Last night while at work my son placed the switch into the dock it asked to update and you guessed it he clicked it. I get home and it was now on 8.1.0. So i figured since i had my backup I could just restore it. It went all bad from that point. When I went to restore it, it said I was missing some files. I should've had 15 i think and I only had 13. So now i'm on 8.1.0 and I can boot into payload but I don't have a full functioning backup and the switch currently won't load any screen.

Am I totally screwed or does anyone have any info that could help me? I'm lost and would appreciate any help if there is hope.
Thanks in advance.

Which custom firmware are you using? Atmosphere, which is recommended, fully supports 8.1.0.

Edit: You should also take steps to block updates and make an adequate NAND backup.

Yes it is atmosphere

Yes it is atmosphere

I also tried to make a backup with the 8.1.0 but I didn't know if that was a good idea seeing as it won't boot after the failed restore

Download Atmosphere 0.9.1 and put it onto your SD card. Boot the Switch using fusee-primary (next to the Atmosphere 0.9.1 download). What happens?

the fusee-primary is currently in the payloads folder, are you saying put it in the atmosphere folder then boot?

I'm saying boot with fusee-primary using Tegra or whatever it is you use to boot the Switch while it's in RCM.

That should go wherever you are pushing the payload from, by a dongle or a phone/pc program.

it didn't boot with the fusee-primary bin, it will only boot with the hekate_ctcaer_4101 bin

oh, and im using the tegraRCM gui to boot it, if that helps anything

 

[eskinner3742]

Try going here: https://github.com/Atmosphere-NX/Atmosphere/releases

Download atmosphere0.9.1-master zip and fusee_primary.bin found under assets

Delete the atmosphere folder, sept folder, and hbmenu.nro from your switch's sd card first

Then drag the new ones from the atmosphere master zip you just downloaded. (You can merge the switch folder but delete the other ones first before copying the new ones)

Then, use the fusee_primary.bin as your payload and let us know what happens. With all luck you should boot right up on 5.1

If you don't mind, try deleting everything except for the Nintendo folder and try again. Make sure there's nothing you really need or back it all up.

Have you ever attempted a downgrade or have you restored any part of your nand backup?

 

[eskinner3742]

You could try wiping and updating in maintenance mode.

yes i tried to restore my nand backup and got errors saying i was missing a file. I can't boot in order to use choidujor unless there is another way to do it

That probably explains the error. As long as your keys are intact you can try rebuilding your nand (https://switch.homebrew.guide/usingcfw/manualchoiupgrade), it is a long process though and your switch doesn't need to boot afaik.

Did you follow the whole tutorial and did your bis keys pass? And did you install a lower firmware version?

 

[D34DL1N3R]

And did you install a lower firmware version?

Nand backup of 5.1.0 was made
Switch was updated to 8.1.0
Tried to restore the 5.1.0 backup over 8.1.0 & received 'Error Fatal Error: failed to decrypt the package2 header(master key revision 4)'

Yes I did, I've haven't tried anything in a few weeks but im going to retry this process tonight. I'll let you know.
