Hacking Question How to read prodinfo.bin file - Switch 8.0?

[HTR-Info]

Hello,
I have a switch in 8.0 on which I dump the partition PRODINFO with Hekate, so I have the file prodinfo.bin.
I wanted to know how to read it to recover the Device ID?
I also have the keys.prod file if needed.
Thank you.

You need read the cal0 as binary itself, there are the data structure:

open PRODINFO in a hex editor like HxD, make sure the first 5 bytes are 43 41 4C 30 07 (the decoded text on the side should read CAL0.), so that you know it's been decrypted properly.
offsets 0x546-555 contain the device ID. you can ignore the "NX" before that and only need those 16 digits.

if you see a bunch of gibberish instead, then it wasn't decrypted properly/at all. you mentioned usage of Hekate but not HacDiskMount, so i'll assume you need to decrypt it. i copied these instructions with some changes from the readme file for SwitchSDtool.

Download and use Lockpick_RCM in conjunction with Hekate CTCaer Mod to dump your NAND and keys if necessary (a NAND dump isn't really needed if you already have one, but i would at least recommend having an updated copy of your keys)
Download HacDiskMount and use it to open up rawnand.bin
Double click on PRODINFO
Open up your keys document and copy in the first 32 characters from 'bis_key_00' to 'Crypto (Upper)', and the last 32 characters to 'Tweak (Lower)'
(The same keys can be gathered from a biskey document)
Click on 'Test', make sure the result says 'Entropy OK'
Click on 'Browse' under 'Dump to file', and browse to where you want to save the file
Click on 'Start'

Hi, I created a simple app which displays the device ID, also has the option to dump it to a file. Hope this helps.

If you wiped your prodinfo using incognito and you don’t still have the backup that incognito make AND you don’t have a nand backup of you switch, then you have lost your prodinfo.

As for your psp question, you’re better off asking in the psp section.

 

[Danook28]

Yes lost prodinfo...
