4. Initial Setup & First Boot

Connect to your TVPlug the included HDMI cable into the HDMI port on the ColaBox L2 Plus and into an available HDMI port on your TV.

Power onConnect the power adapter to the device and plug it into a wall outlet. The LED indicator will light up.

Select the TV inputSwitch your TV to the matching HDMI input (HDMI 1, HDMI 2, and so on). The ColaBox boot screen appears within about 30 seconds.

Pair the remoteHold Home and Back together for 3 seconds to enter Bluetooth pairing mode, then follow the on-screen prompt.

Connect to the networkSelect your Wi-Fi network and enter the password, or plug in an Ethernet cable for the most stable connection.

Sign in to your Google accountThis gives you access to the Google Play Store and personalized recommendations.

Tip: For the most reliable 4K streaming, connect the Gigabit Ethernet port to your router. A wired connection avoids Wi-Fi interference entirely.

5. Remote Control Guide

6. Network & Wi-Fi Connection

Wi-Fi setup

Go to Settings → Network & Internet → Wi-Fi, select your network and enter the password. Use the 5GHz band where available for faster, more stable streaming. The external antennas noticeably improve range — point them upward.

Wired Ethernet (recommended)

Plug an Ethernet cable into the RJ45 port. The device detects and configures the connection automatically — nothing else to set up.

Note: A minimum of 25 Mbps download speed is recommended for 4K HDR streaming. If you experience buffering on Wi-Fi, switching to Ethernet resolves it in most cases.

7. Installing & Managing Apps

The ColaBox L2 Plus runs Android 14.0 with full access to the Google Play Store.

Install from Google Play

Open the Google Play Store from the home screen.
Search for the app you want.
Select Install and wait for the download to finish.

Sideload an APK (advanced)

Enable Unknown Sources under Settings → Security.
Transfer the APK via USB drive, or download it in a browser.
Use a file manager app to locate and install it.

Important: You are responsible for ensuring any app you install and any content you access complies with the laws in your jurisdiction and with each service's terms of use.

8. Display & Picture Settings

Go to Settings → Display & Sound → Picture:

Resolution: Auto / 4K (3840×2160) / 1080p / 720p
Refresh Rate: Auto / 60Hz
HDR Mode: Auto-detect (HDR10+ / HDR10 / HLG)
Color Space: Auto / YCbCr / RGB
HDMI Range: Auto / Full / Limited

Tip: Leave Resolution and Refresh Rate on Auto — the box will match whatever your TV actually supports.

9. Audio Settings

Go to Settings → Display & Sound → Audio:

Optical SPDIF output: Digital audio to a soundbar or AV receiver, with Dolby Digital / DD+ passthrough
Audio Passthrough: Set to Auto for bitstream output to a receiver
Bluetooth audio: Pair wireless headphones for private late-night listening
Volume control: Remote, or your TV via HDMI-CEC

Tip: If you own a soundbar or AV receiver with an optical (TOSLINK) input, use it. Optical passthrough gives you true multi-channel Dolby Digital instead of a stereo downmix through the TV speakers.

10. Storage & Memory Management

Internal storage

64GB onboard. Check usage at Settings → Device Preferences → Storage and clear app caches from there if space runs low.

Expanding storage

Insert a TF (microSD) card, or connect a USB drive, for extra media storage. You can also format external media as internal storage to install more apps.

Warning: Formatting a card or drive as internal storage erases everything on it. Back up your files first.

11. FAQ & Troubleshooting

No signal on the TV

Confirm the TV is on the correct HDMI input. Try a different HDMI cable or a different port on the TV. Check that the LED on the device is lit.

Remote not responding

Re-pair it: hold Home + Back for 3 seconds. If the remote LED does not flash at all when you press a button, replace the batteries.

Wi-Fi keeps dropping

Switch to the 5GHz band, reposition the external antennas, move the router closer, or use a wired Ethernet connection for full stability.

An app crashes or freezes

Go to Settings → Apps → [App Name] → Clear Cache. If it continues, uninstall and reinstall the app.

4K content is not playing in 4K

Check that your TV supports 4K, that you are using a High Speed HDMI cable, and that the service you are streaming from offers 4K on your plan.

How do I factory reset?

Go to Settings → Device Preferences → Reset → Factory Reset. This erases all data and returns the device to factory defaults — use it as a last resort.
