Homebrew Question Would it be "legal" for me to post "blank" boot0 / 1 for repair purposes?

[Adran_Marit]

Oh bummer hope he's doing well. I'll take a look, thank you

I would but I'm missing my keys.txt and boot0/boot1

Here was my original post on Reddit so you guys know where I am at with the switch , they sent me here .

Details: I was attempting to restore a switch to stock to play online.
The switch is unpatched and fully exploitable

I knew I had made backups in the past but like an idiot lost the boot0 and boot1 and flashed my nand before checking my backup folder.

I also made the mistake of flashing a different boot0 / boot1 thinking they were universal. False. Now obviously I cannot boot normally.

What works: rcm, hekate,

What files I do have: a old nand backup v. 9.x.x
prodinfo.bat and biskeys.bat from atmosphere auto backups
A bis_keyt.txt that I was able to dump via rcm

What I'm missing (from most guides to solve this issue I've read):
Tsekeys and keys.txt and obviously boot0/boot1

I've read about a modified boot0/boot1 that may help but I can't seem to find the files on xbins.

If someone could tell me if I'm screwed or if there is hope I'd appreciate it !

Ok I'll look more thoroughly , is there a specific keyword to search I'm not familiar with xbins and I get nothing when trying to search for boot0 .
Thanks !

Its under /switch/cfw/_cfwtools/bootrepairpackage

Also if you can't find it and need help doing the choidujour stuff shoot me a message as I also help people doing the downgrade process

Just wanted to say thanks to everyone for helping meout ! I managed to get it back and running again with the instructions lyuboa sent me.

 

[Thundermofocat]

What FW are you running? Not v9.0.0 by any chance? If so, BIS key derivation is different.

Use Lockpick_RCM latest version. This is compulsory.

what is the password?

 

[Draxzelex]

Just use ChoiDujour.

 

[Thundermofocat]

It has to be using the later method of getting the BIS keys. The only thing I can think of.

You are lucky it isn`t patched. ITs right on the borderline of the ipatched models.

i'm having trouble to pass Prodinfo. in case i dump the BIS_keys and he doesn't match..... and i get FAIL ENTROPY everytime. any suggestion?

He hasn't logged on for several months and there's no indication so far that he is coming back.

[Thundermofocat]

im trying, but ChouiDujour everytime shows "invalid keys" or "problem with NCA header"

 

[LeyendaV]

A GitHub repository would be a better fit, I assume. Legal or not, not sure if having that kind of stuff here would be safe.

How did you obtain the keys?

 

[Thundermofocat]

How did you obtain the keys?

via Lockpick_RCM

 

[Draxzelex]

via Lockpick_RCM

Did you use the latest version of Lockpick_RCM?

 

[Thundermofocat]

Did you use the latest version of Lockpick_RCM?

yes

 

[Draxzelex]

yes

Open up the keys file and ensure it only contains the following keys:
master_key_00 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
master_key_01 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
[... all master_keys through the latest one required by the firmware you're trying to install]
header_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
aes_kek_generation_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
aes_key_generation_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
key_area_key_application_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXX
key_area_key_ocean_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
key_area_key_system_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXX
package2_key_source = XXXXXXXXXXXXXXXXXXXXXXXXXXXX

so...... i have the master key source . but no the master key 00 / 01 , and no signal of the key_area_key_* too

Did you use Incognito?

Okey, you can find a complete list of keys that are universal if you Google enough. Unique keys however aren't as simple if you don't manage to get info from the NAND.

and what i should do?

Since you wanna install some update I recon, you want to get the global key list. So Choidjour can open it.
