#### 🛠 Jailbreak Steps with Palera1n

**Step 1: Check iOS Version**

* Go to **Settings → General → About → iOS Version**

**Step 2: Install Palera1n**

* Visit palera.in
* Download and install via terminal:

  ```bash
  sudo mkdir -p /usr/local/bin
  sudo mv ./palera1n-macos-universal /usr/local/bin/palera1n
  sudo xattr -c /usr/local/bin/palera1n
  sudo chmod +x /usr/local/bin/palera1n
  ```
* **Note for iPhone X (A11 chip):**\
  You **must disable the passcode** before jailbreaking.

**Step 3: Trigger Jailbreak via DFU Mode**

* Plug device into Mac
* Run `sudo palera1n` in terminal
* Press buttons to enter **DFU Mode**

**Step 4: Wait for Installation**

* Wait up to 2 minutes
* Palera1n app appears on device
* Open and set a **custom root password**

**Step 5: Install Sileo Repository**

* Open **Sileo app** post-JB
* Ready to install tools like **Frida**

**Step 6: SSH Connection Setup**

* Palera1n uses **OpenSSH on port 44**
* Run `iproxy 22 44` for USB SSH tunneling
* Default SSH credentials: `root:alpine`
* Change using `passwd` post-connection

#### 🚧 Common Jailbreak Issues

* Missing Sileo app → Re-jailbreak required
* Device unsupported → “Ignoring non-arm64” error
* DFU mode not detected → Retry buttons or cable
* Better success with USB-A cable over USB-C

***

#### 🛡 Frida Setup

* Once jailbroken, add Frida tooling via Sileo
* Frida is instrumental in conducting **dynamic analysis** on iOS apps
