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

@linuxares ill check v9.0.0

 

[linuxares]

Very strange, I will try to redump today so we can double check. Or if it's just something with copying with the files from the SD or such via FTP. Who knows.

Just checked. v9.0.0 are 16 bytes off too...

In my Switchboot, the backup/restore system is different. I am unsure if its a hekate problem or SD card problem maybe?

I dumped with Switchboot and they are perfect.

Oh my... uhm... this is bad. Is it a new thing with Hekate? Or is it Switchboot? Maybe we should ask @CTCaer happen to know?

Need more BOOT0 dumps to confirm.

I`ll do a dump with Hekate and test.

Lemme see what I can do. I can boot my unhacked Switch and dump it's data to see.

 

[Mikeltii]

Ive sorted it mate.

Updated by test board to v9.0.1 and pulled / scrubbed the boot0 from it.

Thank-you!

Hey mate any luck with my keys to rebuild a new rawnand? Im gonna try now that boot0/1 files see what does

OK... Results are in...

Its your end sir.

Dumped with Hekate (without nyx), with nyx and Switchboot and all dumps are identical.

Somehow, in the past, your boot0 has lost 16 bytes.

wtf, so strange... do you use the Kosmos package? Because that's what I run.

Nope. Straight from Git.

 

[linuxares]

Nope. Straight from Git.

Gonna try that and see if makes a difference, it shouldn't. But man, this is good that you found. Maybe all my previous backups are borked then even if I got success from Hekate.

Could be due to SD speed.

Try lockpick.

If your correct keys are generated, then I wouldn`t worry about it.

That said, if you ever downgrade to 6.1.0 or under, be VERY CAREFUL as with the blobs being wrong, BIS keys will be wrong.

Though they might be right on the emmc and its just the dump that is off.

Or worse, the dump is right and the blobs are indeed 16b off.

That's what I'm trying to figure out. Maybe it's suppose to be 16 bytes different now days? Who knows! Since my unmodified Switch have a different SD Card, it shouldn't be an issue.

@linuxares ill check v9.0.0

just out of curiosity I check my boot0 file and it look like the one you pictured in that post.
I used hekate_ctcaer_4.9 to dump them and transpered it via FTP from SX OS ^^

No worries ! I appreciate that

 

[mattytrog]

Looks like 16b is being lost over FTP?

The blobs start at 0x180000 I promise.

I don`t use FTP. Too slow for what I need.

 

[Baoulettes]

so like this ? (sure to be sure I as I am no familiar with these files and so I need to be sure backups are fine eheh)

That is correct.

 

[Mikeltii]

That is correct.

Im a little bit curious what you guys checking on boot0?

Keyblobs.

Somehow, 16 bytes are being lost in (FTP?) dumps/transfers.

If these boot0 were restored, keyblobs would be permanently messed up, leading to incorrect key derivation. Though keyblobs are not used in derivation of most(all?) keys nowadays.
