On the Taobao Amoy 4.3 yuan shipping USB to TTL programmer cable, disassemble and solder the GND, TX, and RX lines (refer to the previous guide for detailed steps).
1. Change the box’s IP address:
Since the Heilongjiang Unicom IPTV box is typically connected via PPPOE, it's usually linked directly to a router's LAN port. To change this, switch to automatic IP mode. Press the "Setup" button on the remote control, use the default password “123456â€, and in the wired network settings, switch from PPPOE to DHCP. The box will then receive a new IP address automatically.

2. Connect the GND of the box to the TTL GND, the RX of the box to the TTL TX, and the TX of the box to the TTL RX.
3. Open a terminal tool like HyperTerminal, PuTTY, or SecureCRT. Locate the correct COM port in the Device Manager and set the baud rate to 115200.

4. When the box starts up, you'll see some scrolling text. Press Enter to get the prompt `root@HG680:/ #`.
5. Download the latest version of the Sofa Butler desktop app, copy it to a USB drive, and rename it to `shafa.apk` for easier command execution. Insert the USB into the box and observe the terminal output. Once done, use the `df` command to check the USB mount path.
I am here at `/mnt/sda/sda1/`, so enter the command `adb install /mnt/sda/sda1/shafa.apk` to install the Sofa Butler.
6. After installation completes, run `pm list package` to check if `com.shafa.tvlauncher` appears. If it does, the installation was successful.
7. Disable the remote control and upgrade services to prevent them from interfering with the Sofa Butler after an update:
```bash
pm disable com.fh.tr069
pm disable com.fiberhome.fhupgrade
```

8. Launch the Sofa Butler by running `am start com.shafa.tvlauncher`. You should now see the Sofa Butler desktop. Go to the setup menu and enable startup boot. From there, you can freely install other apps.

9. If you want to watch IPTV again, switch back to PPPOE mode and reconnect the network cable as before.
This process allows you to customize your IPTV box and enjoy more flexibility with third-party applications. Make sure to follow each step carefully to avoid any issues.
