# C6: Encrypting the EBOOT

Next, download and extract [RPCS3PatchEboot](https://github.com/tge-was-taken/RPCS3PatchEboot/releases/download/v1.4/RPCS3PatchEboot.1.4.zip). Put the decrypted **EBOOT.ELF** that we created in [Chapter 5](/installation-guide-hardware/c5-decrypting-the-eboot.md) and the **patch.yml** that we created in [Chapter 4](/installation-guide-hardware/c4-creating-the-patch.yml.md) into this folder. It should look like this:

Now, in order for the tool to work, we need to open a CMD window here. To do so, type cmd in the bar at the top, like this and click enter.

Copy this exact text, paste it in the command window and press enter

```
"RPCS3PatchEboot.exe" "EBOOT.ELF" "patch.yml" "EBOOT2.ELF"
```

{% hint style="info" %}
If you get an error during this step, return to [Chapter 4](/installation-guide-hardware/c4-creating-the-patch.yml.md) and make sure you're copying the patches correctly and didn't miss a single step. Also make sure all the files are in the folder and named correctly.
{% endhint %}

After that, you'll see a file named **EBOOT2.ELF**; move that file to the same folder that has the *TrueAncestor SELF Resigner* tool that we used in [Chapter 5](/installation-guide-hardware/c5-decrypting-the-eboot.md).

<figure><img src="https://3517447842-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FGoHg6F5JKG5QaZJ7PfHd%2Fuploads%2FBbxv1QKIqjg6CjxmkVrk%2Fimage.png?alt=media&amp;token=d5ac3666-cd32-4478-9505-84c4fea68055" alt=""><figcaption><p>this is the program we'll be using (again)</p></figcaption></figure>

{% hint style="warning" %}
Your vanilla/unmodded **EBOOT.BIN** might still be here. It would be wise to back it up if you haven't already done so, since we will be creating a new one here. Do not proceed if you don't have a backup made.
{% endhint %}

Rename the EBOOT2.ELF to EBOOT.ELF and open the resigner tool. If you already had it open from before, close it and reopen it.

* If you're using *HEN*, change the **Output Method** to **\[3.XX STD]** and change the **Compress Data** option to **\[OFF]**. Refer to [Chapter 5](/installation-guide-hardware/c5-decrypting-the-eboot.md) if you've forgotten how to do this.
* If you're using *CFW*, don't change anything. Proceed to the next step.

Now, this bit changes depending on your game version:

* If you have a dumped disc version of the game (**BLUS31604** or **BLES02247)**:
  * Press 2 and then hit enter, that's it.
* If you have the PSN version of the game (**NPUB31848** or **NPEB02436)**:
  * Press 3 and then A. You will be asked for a custom ContentID.&#x20;
    * If you have the **NPUB** version of the game, paste this in: \
      `UP2611-NPUB31848_00-HDDBOOTPERSONA05`
    * If you have the **NPEB** version of the game, paste this in: \
      `EP4062-NPEB02436_00-GPERSONA5X000001`.&#x20;
  * Finally, press Enter and you should get your new, patched **EBOOT.BIN**.

***

Now that we have a patched **EBOOT.BIN**, put it in your folder. It should be looking like this:

We have downloaded and built everything we needed. Move on to the next chapter!
