+
+---
+
+## ✅ What This Guide *Is* (and Is Not)

+- Validated on 2023–2025 Samsung firmware
+- Designed to **prevent silent failures**
+- Focused on **practical install** with known quirks
+- Includes full certificate + CLI steps
+
+**This guide _is not_:**

+
+---
+
+## 🧰 Requirements
+
+**Hardware**
+- Samsung Smart TV with **Developer Mode**
+- TV and computer on the **same local network**
+
+**Software**
+- Windows / macOS / Linux PC
+- Internet access
+- Administrator permissions on your PC
+
+**Files**

+
+---
+
+## 🧱 Step-by-Step Instructions
+
+### 1️⃣ Enable Developer Mode on the Samsung TV
+
+- Open **Apps**
+- Open Developer Mode (hidden menu — varies by model)
+- Set:
+  - Developer Mode: ON
+  - Host PC IP: your computer’s local LAN IP (e.g. `192.168.1.25`)
+- Reboot the TV when prompted
+
+> ⚠️ **Do not use `127.0.0.1` at this stage** — that comes *after* first install.
+
+---
+
+### 2️⃣ Install Tizen Studio
+
+- Download from the [Samsung Developer site](https://developer.samsung.com/tizen)
+- Choose **Custom Install**
+- Select:
+  - Tizen SDK Tools
+  - TV Extensions
+  - Samsung Certificate Extension
+  - Tizen Web App Development
+
+---
+
+### 3️⃣ Install Required Packages
+
+In Tizen Studio:
+- Tools → Package Manager
+
+Install these packages:
+
+**Mandatory**
+- Tizen SDK Tools
+- TV Extensions
+- Samsung Certificate Extension
+- Tizen Web App Development
+
+**Strongly Recommended**
+- Samsung TV Emulator
+- CLI tools
+
+Restart Tizen Studio.
+
+---
+
+### 4️⃣ Tool Locations (Critical)
+
+#### Windows
+```
+C:\tizen-studio\tools\sdb.exe
+C:\tizen-studio\tools\ide\bin\tizen.bat
+```
+
+#### macOS / Linux
+```
+~/tizen-studio/tools/sdb
+~/tizen-studio/tools/ide/bin/tizen
+```
+
+> ⚠️ These tools are *not* added to PATH by default
+
+---
+
+### 5️⃣ CRITICAL: Correct Use of `sdb`
+
+macOS / Linux:
+```
+cd ~/tizen-studio/tools
+./sdb devices
+```
+
+Windows:
+```
+cd C:\tizen-studio\tools
+sdb devices
+```
+
+---
+
+### 6️⃣ Connect the TV to the PC
+
+```
+sdb connect <TV_IP>:26101
+sdb devices
+```
+
+Expected output:
+
+```
+<TV_IP>:26101    device    <TV_MODEL>
+```
+
+If the TV does not appear as a device, stop here and fix this.
+
+---
+
+### 7️⃣ Create Samsung Certificates
+
+In Tizen Studio:
+- Tools → Certificate Manager
+- Create a new Samsung certificate profile
+- Create:
+  - Author certificate
+  - Distributor certificate
+- Add the TV DUID
+- Sign in with a Samsung account if required
+
+---
+
+### 8️⃣ Activate the Certificate Profile
+
+Check profiles:
+```
+tizen security-profiles list
+```
+
+You must see:
+```
+myprofile   O
+```
+
+If not active:
+```
+tizen security-profiles set-active -n myprofile
+```
+
+---
+
+### 9️⃣ Re-Sign the TizenBrew Package
+
+You must re-sign the downloaded `.wgt` file:
+
+```
+tizen package -t wgt -s myprofile -o ./resigned -- TizenBrewStandalone.wgt
+```
+
+Confirm output file exists:
+```
+ls ./resigned
+```
+
+You should see:
+```
+TizenBrewStandalone.wgt
+```
+
+---
+
+### 🔟 Install the Package (THE KEY STEP)
+
+> ⚠️ Do NOT use `sdb install` — it does not register the app!
+
+Install using:
+```
+tizen install -n ./resigned/TizenBrewStandalone.wgt -t <DEVICE_NAME>
+```
+
+You must see:
+```
+install completed
+Tizen application is successfully installed.
+```
+
+---
+
+### 1️⃣1️⃣ Launch TizenBrew
+
+On the TV:
+- Open Apps
+- Look for the beer glass icon
+- Launch TizenBrew once
+
+---
+
+### 1️⃣2️⃣ Final Developer Mode Configuration
+
+After first launch:
+- Open Developer Mode again
+- Set Host PC IP to:
+```
+127.0.0.1
+```
+- Fully reboot the TV (long power press)
+
+---
+
+### 1️⃣3️⃣ Install TizenTube
+
+- Open TizenBrew
+- Install TizenTube
+- Exit
+
