Hello mattytrog,

I've tried Unbrick_Your_Switch and the firt time I've done it, by launching fusee-primary.bin, I got the message : ERROR : Fatal Error: (NXBOOT) Key derivation failed !
Now I can't start switchboot.bin ( Atlas NX logo is displayed, Nintendo logo is displayed and ... black screen). Try to repeat the complet procedure but still the same result (cannot start switchboot.bin anymore).

Do you have any id about what is going wrong ? (All steps were successful the first time excepted the non successful start of fusee-primary.bin)

OK... What steps did you do?

I`ve just (for shits and giggles) purposefully corrupted 2 consoles. Flashed v9.00 boots on v7 Main and sub partitions, with a 8.0.1 SYSTEM / USER partition. Equal amount of fuck-uppery on the other one.

Took a rawnand first obviously. But using the unbrick pack, I unbricked perfectly.

What steps did you do?

@linuxares checking now

Hmmm...

Keyblobs appear to start at 17FFF0 on 9.0.1

This is 16 bytes before they normally start @180000

I don`t have any units on 9.0.1.

@linuxares ither they have moved the keyblobs 16 bytes backwards, or it is a bad dump.

Can anyone confirm?

Look at 0x17FFF0 (9.0.1 only)

Is it empty or occupied?

Hello

Can your pack save a switch that only boots in 5.1.0. For if it is passed on a version 9.0.0 it indicates the error code 2168-0002.
Whether it is by an official update or by choidujournx.
And if it is good could you pm because I have not yet my 5 post on the site.

thank you

Sry for my english i use googletrad

Hello mattytrog,

I follow your tuto \Brief_Instructions.txt (not \Unbrick_Your_Switch_iha2\Brief_Instructions.txt) with success until the step "Launch fusee-primary.bin". After starting Launch fusee-primary.bin, I've gotten the message : ERROR : Fatal Error: (NXBOOT) Key derivation failed !

I have valids Rawnands from the time when the switch was in 6.01 and 6.1 (not used for this procedure). I've also all the keys, included the BIS one.
In order to do the step 5 (Restore using BIS keys), I've used MemLoader V3 ( I had to put some files in on the SD card) to establish the connection with HacDiskMount. No problem with the "check entropy". No problem at all.

I guess that the Boot0 is now "not valid" and that's why Switchboot.bin can't boot anymore.

Sounds like a theme problem to me.

Remove theme in 5.1.0, then update

That a nice thread I will pin somewhere in case !
And some nice information about prodinfo it remind me something ;)

Btw if you need dump of boots from lastest version to cross check feel free to ask ^^
Ive sorted it mate.

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

Thank-you!

Was my dumps fine then?
It was off by 16 bytes.

Compared to mine that I have just dumped.

If it hasn`t been altered by yourself, I`d double-check your dumping software. If you would have restored the boot0 you gave me, your keyblobs would be fooked.

But it gave me a valuable insight. Thank-you sir!
