Hacking Question Cant boot OFW or CFW.. What should I do?

[rhoody123]

I can enter hekate but I dont really know how to go forward to restore it..
Will downgrading and updating it again fix it? Error code is 2002 4686 in both ofw and atmosphere when i boot up.
I have tried restore to factory but the same error comes up when i do it.
Any help would be greatly appreciated!

Did you backup your nand? If yes restore it

 

[rhoody123]

I was too stupid to back it up before this happened.. So there is nothing I can do then? I was hoping there was someway I could restore the system by downgrading and updating again. But this is getting so complicated that im starting to really lose hope

Can you give more detail to what lead to you having the error?
Like what Firmware you are on? etc...

 

[rhoody123]

OFW was 9.0.0 and I was using the latest version of Atmosphere.. And stupidly in the atmosphere file browser I tried to copy a file to the user partition from SD to save space.. Thats when it rebooted and the error started.. I dont care if I get banned, I just want to get into the actual firmware and play games again

 

[RHOPKINS13]

Do you remember which file you copied? If you used HacDiskMount to access your user partition, could you undo it?

 

[rhoody123]

It was a game I think.. But yeah I was thinking of that but I have a hard time accessing the partition i hacdisk.. The other thing is that it shut down so fast it really didnt get any time to copy anything.. as soon as i pressed paste it restarted to error. But Ill try to educate myself better with hacdisk and see if i can see the file

 

[rhoody123]

Im stuck guys.. I cant dump anything in hacdisk, so I really dont know how to access the user partition.
Can I create and use emunand if my ofw wont boot? Im just trying to find some kinda solution to get it working

 

[RHOPKINS13]

This is why we ALWAYS ALWAYS ALWAYS make a nand backup before doing ANYTHING with the Switch! And every guide will tell you that!

You should be able to rebuild your nand by following the guide here:
https://switch.homebrew.guide/usingcfw/manualchoiupgrade

In all likelihood you will probably get banned if you ever try to go online, but that's the risk you took by not having a clean backup. Better luck next time.

Yeah man I f-ed up.. For anyone who sees this BACK UP!!! this is not an easy situation to get out of.. But yeah I have started this guide but Im stuck on getting the keys.txt file to work with choirdujour.. Always some fail or file not found! Anyone that can help me get through that step?

And thanks for helping this far! Good to know there is a way to get it back

Dump your current nand with hekate, then use hacdiskmount to mount the user partition. Fix whatever you broke, then restore the nand.

 

[rhoody123]

Progress this far is I have took my prodkeys file and made it to a txt file and copied it into the choirdujour dir.. I dont know if this is the correct keys to use but I saw somewhere they mentioned it as an easy way. I use the command ChoiDujour.exe --keyset=keys.txt fw in cmd and i get I failed to match keys lines but the last line says its unable to open a firmware nca file. And thats where im stuck

I tried to mount but Im gonna be honest and tell you I dont get the way it works. I have dumped everything I can from hekate.. And when i open the rawnand.bin.00 file I get the list of partitions.. But now I dont know what to do.. I cant access it from here, and when i press dump i get a cryptolayer.cpp error

You can get your Keys with Lockpick.

Rename your generated prod.keys file to keys.txt.

You can use Biskeygen to generate your BIS Keys.

For Choidujour to work you need a Firmware lower then 6.x.x, i'd take 5.1.0 for example.
You can find them on xbins.

Just follow the mentioned Guide and you should be good to go.

You need to delete the extra keys in the ChoiDujour error. If you have too many extra keys, it refuses to load.

If you care about your profiles and game saves, backup your current nand. I know its broke at the moment, but 9.0.0 makes changes to the system saves that make the incompatible with lower firmwares. If you downgrade, you will have to delete your system saves, which include your profiles, and you will have to install everything again, and start over.

I have deleted every line that fails.. Do I need to delete more?
The problem is the last line

unable to open "C:\Users\Robin Sørdal\Desktop\choi\fw\0167eed4b60b824c8f7c37dXXXXXXXX.nca": No such file or directory. Code: 1
[14212] Failed to execute script ChoiDujour

I xed out some of the numbers because I dont know if it is allowed or a critical key
