prodinfo_gen 
prodinfo_gen is a Nintendo Switch payload that can generate minimal, console-unique, PRODINFO files.
It can either build one from scratch or import parts of a donor PRODINFO.
It is primarily aimed at people without a backup of their PRODINFO or building a NAND from scratch.
This tool is not meant to, and will not, unban a Switch console.
Limitations
Of course, as we do not have Nintendo's private keys, the generated files can't be perfect.
Here's what works:
| Booting | Homebrews | Amiibos | GameCards | Online | |
|---|---|---|---|---|---|
| from scratch | ✓ | ✓ | ✓ | ||
| from donor | ✓ | ✓ | ✓ | ✓ |
As such, a "from scratch" PRODINFO also acts as a more elaborate "Incognito".
USE THIS TOOL AT YOUR OWN RISK, DO NOT OVERWRITE A FACTORY PRODINFO WITHOUT MAKING A BACKUP FIRST.
Usage
- If you want to use a donor PRODINFO, place it at
sd:/switch/donor_prodinfo.bin. Note: If the donor is a patched or Mariko Switch, you will need to copy the donor's keys tosd:/switch/donor.keys. - Launch prodinfo_gen.bin using your favorite payload injector or chainloader.
- You should find
sd:/switch/generated_prodinfo_from_scratch.binorsd:/switch/generated_prodinfo_from_donor.bindepending on what you selected. - You can now write that PRODINFO to your NAND using a tool such as HacDiskMount (it is recommended to make a backup of the current PRODINFO first).
Building
Install devkitARM and run make.
