SunPlus Box TV 120 — Free Firmware Update Guide

Warning: Incorrect firmware updates can brick devices. Proceed at your own risk. This guide assumes you accept that risk and that you are updating a SunPlus-based TV box model labeled “120” (consumer Android/TV box with SunPlus SoC). If your model differs, stop and verify model number on the label.

What you’ll need

  • A Windows PC (or Linux) with USB ports and basic file tools.
  • A microSD card (preferred) or USB flash drive (formatted FAT32). Recommend ≥8 GB.
  • A microSD card reader or ability to connect the storage to the box.
  • The correct firmware file for your exact model (matching model number and board).
  • A basic text editor and ability to run adb/fastboot or recovery if needed.
  • Patience and at least 20–30 minutes.

Step 1 — Identify exact model and current firmware

  1. Power on the box and open Settings → About (or System → About). Note:
    • Model number
    • Build number / firmware version
    • Board/chip info (if shown, look for SunPlus or SPxxxx)
  2. If you can’t boot to system, check the label on the bottom of the device for model, serial, or board ID.

Step 2 — Obtain the correct firmware (free)

  1. Official firmware: Check the manufacturer’s support page first (search by model). Use only firmware that exactly matches your model/board.
  2. If manufacturer files are unavailable, search reputable forums (XDA, FreakTab, or dedicated TV-box forums) for the exact model and SunPlus 1xx/2xx board. Look for posts with verified user feedback and a checksum.
  3. Verify any downloaded firmware:
    • Check MD5/SHA1 if provided.
    • Inspect forum comments for successful flash confirmations. Do NOT use firmware for other models/boards.

Step 3 — Prepare update media Option A — microSD / USB update (most common)

  1. Format the microSD or USB drive to FAT32.
  2. Extract the firmware package. Common filenames: update.img, update.zip, or system.tar.
  3. Rename the firmware file as required by your device’s update method (common names: update.img, sunplus_update.img, upgrade.zip). Check manufacturer instructions or forum thread.
  4. Copy the file to the root directory of the microSD or USB drive.

Option B — USB-to-Serial or USB flashing tool

  1. Some SunPlus devices require a special USB flashing utility on PC or a TTL serial connection—follow the vendor or forum instructions if your device is one of these.

Step 4 — Boot into update mode and flash Method A — SD/USB automatic update

  1. Power off the box and unplug power.
  2. Insert the prepared microSD or USB drive.
  3. While holding the device’s reset button (often a small pinhole; use a paperclip), plug in power.
  4. Keep holding reset until LED/boot messages indicate update (or until device powers through an update sequence).
  5. Wait until update completes (may reboot automatically). Don’t unplug power during flashing.

Method B — Manual recovery menu

  1. Boot into recovery (often via holding reset or a remote-key combination at boot).
  2. In recovery, choose “apply update from external storage” or similar.
  3. Select the firmware file and confirm.
  4. Wait for completion, then reboot.

Method C — PC flashing tool

  1. Run the vendor-provided flasher on PC (or open-source SunPlus flasher if required).
  2. Connect box to PC via USB (or serial) per instructions.
  3. Load firmware image and follow tool prompts to flash.
  4. Wait for successful completion and reboot.

Step 5 — After update

  1. First boot may take several minutes—be patient.
  2. Check Settings → About to confirm the new build/version.
  3. If device becomes unstable: try factory reset in Recovery, then re-flash original firmware if needed.

Troubleshooting (brief)

  • Device won’t enter update mode: try different USB port, another microSD, or hold reset longer; confirm correct reset hole/button.
  • Update fails or stops: reformat media, re-download firmware, try different file name variants (update.img vs upgrade.zip).
  • Bricked device (no power/boot): search forums for unbrick method for your board (USB flasher or serial rescue) and follow community-provided steps exactly.

Safety tips

  • Use firmware only from trusted sources and matching model/board.
  • Ensure uninterrupted power during flash.
  • Keep records of original firmware and any checksums.

Risks of DIY Free Updates (Important Warning)

While the update is free of monetary cost, there is a technical risk:

  • Bricking: If you install firmware intended for a different revision of the Box TV 120, the device may become unusable.
  • Lost Data: A manual update will wipe all your installed apps and saved logins.
  • Warranty: Performing a manual flash may void any existing warranty.

How to Get the Free Update (Step-by-Step Guide)

Since the Sunplus Box TV 120 is not an official "branded" device like a Fire Stick or NVIDIA Shield, you cannot rely on an over-the-air (OTA) automatic update. You must perform a manual "Local Update."

Step 1: Identify Your Exact Firmware Version

  • Go to Settings > Device Preferences > About > Status.
  • Write down the Build number and Kernel version. Generic boxes have multiple hardware revisions; using the wrong firmware can brick the device.

Step 2: Source the Correct Free Firmware

  • Method A (Manufacturer): Visit the support page of the specific reseller (e.g., Mecool, T95, or X96—many use Sunplus chips). Search for "Box TV 120 firmware."
  • Method B (Chipset Communities): Search tech forums like XDA Developers or FreakTab.com using the phrase: "Sunplus SP chipset Box TV 120 firmware download free."
  • Caution: Avoid paid firmware sites. Legitimate updates are always free.

Step 3: Prepare a USB Drive

  • Download the .img or .zip firmware file (do not rename it).
  • Format a USB flash drive to FAT32.
  • Copy the firmware file to the root of the USB drive.

Step 4: Install the Free Update

  1. Insert the USB drive into the Sunplus Box TV 120.
  2. Navigate to Settings > System > System Update > Local Update.
  3. Select the firmware file from the USB drive.
  4. Confirm the update. The device will reboot and install the new firmware automatically (this takes 5–10 minutes).
  5. Do not power off the device during this process.

Can You Still Update the Sunplus Box TV 120 for Free?

Yes, in most cases. However, "free" here means using community-sourced firmware or generic Sunplus reference software—not an official OTA (over-the-air) update. The TV 120 runs on the Sunplus 1506C or 1508A chipset, which was widely used in many low-cost FTA receivers. That means firmware from similar models often works.
