Hacking RELEASE Firmware Version Inspector - get FW version from NAND dump

[shchmue]

That did help it seems, however now I'm getting this error.

is your python3 64 bit maybe? this might require 32-bit

The error I always get is:

I tried so many different variations for the paths. With slash, with backslash, with "/c/", with "C:\\", copying the files in different directories, copying everything in the same one and use the file names directly instead of paths.

sounds like you're running this in python2. install python 3 32-bit and try again

you're positive you're running this on Python 3 and not 2? can you send a complete screenshot of the terminal when it errors? feel free to censor names and keys

you're positive you're running this on Python 3 and not 2?

I'd say they're running it on 2... on my mac, when I installed Python using Brew, I got both 2 and 3, and I have to explicitly use "python3" and not just "python" as they did here:

Okay so i solved this error but im getting a new one which another user was having above. I had to copy the Crypto folder from my python directory into FVI-master and got this new one.

Hey just posting for posterity, I got the "contents not found" error a user had above and it was because I had no idea what was meant by "tweak" and "crypt" BIS keys, because my biskeydump version just gave me a single long hex number for BIS key 2. I couldn't find any info on this anywhere so I used an older biskeydump version, and it turns out that the long, 64 bit hex number was actually both combined. I took the first 32 bit half and put it as BIS Key 2 (crypt), and the second 32 bit half and made it BIS Key 2 (tweak). It then worked fine. (Looks like the contents not found error is just when the bis keys are wrong?)

Anyway this is probably a really silly roadblock to have but hopefully this could help any frustrated newbies like me!! Very helpful program, thank you.

Hey guys I am trying to use this program to check the firmware on my backup. However, I keep getting this error. I also tried it, wrapping the Bis Keys numbers <XXXXXXXX> it still did not work, btw that is the only two lines in the biskeys's folder. Any ideas?

remove the spaces before each line, those are only in the info text so that it looks nice :x

Thank you! it works like a charm!.....now i will create another post to see if there is a way to restore a dead switch... lol. But thanks again. its a 6.2.0 backup.. which I restored, but didn't have the boot0 or boot1.

for that you'll need to either do an entire ChoiDujour procedure to any firmware below 6.2.0 (it doesn't support that target yet) or make one of the same firmware version that's in your boot0 and skip flashing boot0/1

So im getting a new error regarding my BIS keys. I had double checked and confirmed its the right one by doing a backup twice. Whats wrong?

EDIT: NVM SOLVED! Forgot to put -b flag

Hey just wanted to say thank you. I was able to downgrade back to 4.1 using my biskeys, ChoiDujour and a keys.txt file that is flying around the internet...Cough Max... Cough site. Now i just have to figure out, hot to boot with 8 burn fuses. all I'm getting is nintendo logo and black screen.

it doesn't boot even with CFW?

 

[tremendazo]

it doesn't boot even with CFW?

It loads shows me the nintendo logo and then it goes black screen. I am using Hekate 4.5 and atmosphere 0.82. Tried both options CFW and stock, but the system says I burned 8 fuses.

 

[tremendazo]

it doesn't boot even with CFW?

....Nm It just boot up with REINX... Super Happy! Thanks again

I keep getting unexpected indentation errors when I put the code in with the biskeys/locations.

Can someone tell me what's wrong and what i'm missing? I've done all I can to try to figure Python on but, man i'm just lost Trying to fix my switch but, don't remember what firmware version was on this when I backed it up.
