Important Disclaimer: The firmware identifier 40-ms801a-mac2hg (often associated with hardware variations of the MS801 or MS801A Main Boards, typically used in LED/LCD TVs) refers to a very specific BIOS/Bootloader configuration.
Because this firmware controls the low-level hardware initialization of a circuit board, using the wrong file or interrupting the installation can permanently "brick" (destroy) the device.
This guide is for educational purposes. Always verify the exact main board sticker on your device before proceeding. Do not flash firmware unless you are certain it matches your hardware.
There are two primary ways to install firmware on MS801 series boards: the USB Update (Service Mode) method and the Programmer (ISP) method.
Over time, the NAND flash memory on these boards can develop bad blocks, or the stored firmware can become corrupted due to power surges, improper shutdowns, or aging components. You should consider updating or reinstalling the 40-ms801a-mac2hg firmware if you experience:
In all these cases, a fresh firmware flash (also called “reflashing” or “forcing a software update”) can restore factory functionality.
The 40-ms801a-mac2hg firmware is the digital heartbeat of a now-aging but still capable lineup of LED TVs. While manufacturers no longer provide over-the-air updates for these MStar-based boards, the USB flashing method remains a robust way to recover a bricked or malfunctioning set. Always prioritize safety: verify file sources, match the exact board suffix, and never interrupt a flash.
With this guide, you now understand not just where to find the firmware, but how to breathe new life into a TV that would otherwise be destined for the landfill. Happy repairing.
Common reasons to flash 40-MS801A-MAC2HG firmware:
Remember: Always ground yourself before handling the mainboard. One electrostatic discharge can destroy the NAND flash containing what little firmware is left on the chip.
Last updated: October 2025 – This guide will not be updated for newer TV models, as the 40-MS801A-MAC2HG platform is considered obsolete. Proceed with caution.

Updating the firmware for this specific board provides several technical improvements:
System Stability: Fixes common bugs that cause the TV to hang or freeze during operation.
Feature Access: May unlock newer versions of pre-installed apps or system settings.
Bug Patches: Resolves issues related to audio-video syncing and network connectivity. How to Update Firmware
Depending on the TV brand using this board, updates can be performed via the system menu or manually via USB. Method 1: Network Update (Recommended)
For working units with internet access, use the built-in update tool:
Navigate to Settings using the TCL Support Guide or the TCL FAQ. Select Device Preferences (or About). Choose System Update > Network Update.
Select Check for Update and follow the on-screen prompts to download and install. Method 2: Manual USB Update If you encounter problems after updating, include:
If the TV is stuck on a logo or cannot access the menu, a manual flash is required:
Contact Support: Reach out to the manufacturer (e.g., TCL Contact Support) to get the specific .bin or .pkg firmware file matched to your screen panel.
Prepare USB: Format a USB drive to FAT32 and copy the firmware file to the root directory.
Initiate Flash: Power off the TV, insert the USB into the designated port, and hold the power button (on the TV cabinet, not the remote) while plugging it back in until the update progress bar appears.
Note: Always verify your specific Panel Number (found on a sticker inside the TV) before flashing, as using firmware for a different panel can result in an inverted or distorted image.
The 40-MS801A-MAC2HG is a specific mainboard used primarily in TCL LED televisions and related brands. Finding the correct firmware for this board is critical for resolving issues like "stuck on logo" boot loops, unresponsive software, or hardware compatibility after a board replacement. Understanding the 40-MS801A-MAC2HG Board
This mainboard is often identified by several related part and board numbers. For instance, similar TCL boards like the 08-SS40TML-LC217AA often share chassis families, such as the MS08GP or MST10P. These boards typically feature: Chipset: Often built around MStar SoCs (e.g., MSD6886).
Storage: 4GB to 8GB eMMC flash memory, which is where the firmware resides.
Common Failure: eMMC wear-out can lead to corrupted firmware, requiring a fresh "flash" to restore the TV. How to Install the Firmware
If your TV is still functional, you can perform a standard update. However, if it is stuck in a boot loop, you must use a "forced" recovery method. 1. Normal USB Update (TV Functional)
Format a USB Drive: Use a drive (less than 16GB is best) formatted to FAT32.
Download and Copy: Obtain the .bin or .pkg firmware file and place it in the root directory of the USB.
Initiate Update: Insert the USB into the TV. Go to Settings > Device Preferences > About > System Update > Local Upgrade. 2. Forced Recovery (For Boot-Loops)
Prepare the USB: Copy the firmware file (often named MstarUpgrade.bin or upgrade.pkg) to the root of your FAT32 USB drive. Power Down: Unplug the TV from the AC power outlet.
Insert and Hold: Plug the USB drive into the TV. Press and hold the Power button (on the TV itself, not the remote) or the CH+ button.
Power On: While holding the button, plug the TV back into the AC outlet. — End of post [Replace X
Watch the LED: When the standby LED starts blinking rapidly, release the button. A progress bar should appear on the screen.

To find and install the firmware for the 40-MS801A-MAC2HG (typically a TCL or generic smart TV mainboard), you generally have two paths: an automatic network update or a manual USB flash. 🌐 Method 1: Network Update (Safest)
If your TV still boots to the home screen, this is the most reliable method to ensure you get the correct version for your specific hardware. Step 1: Press Home on your remote.
Step 2: Go to Settings (gear icon) > Device Preferences > About. Step 3: Select System Update.
Step 4: Choose Network Update. The TV will search for and install the latest official firmware. 💾 Method 2: Manual USB Update
If your TV is stuck on the logo or won't boot, you will need to find the specific .pkg or .bin file.
Search Criteria: Look for the Project ID or Chassis Name (like MS801) on the back of the TV.
File Source: Official firmware is often shared in technician communities or the TCL Firmware Telegram Channel (though not officially affiliated, it is widely used by the community). Process: Format a USB drive to FAT32.
Copy the firmware file (often named Update.pkg or Update.bin) to the root of the drive.
Plug the USB into the TV's USB port while the TV is unplugged.
Press and hold the physical Power button on the TV while plugging it back into the wall. Release when the update screen appears. ⚠️ Critical Warning
Match your Panel: Firmware is often tied to the specific display panel. Installing the wrong "Project ID" can result in an inverted or garbled image.
Power Stability: Never unplug the TV during a firmware update, as this can permanently "brick" the motherboard.
💡 Key Point: Always check your Product Information in the settings menu to find your current Project ID before attempting a manual flash to ensure compatibility.
Is your TV currently stuck on the logo, or are you just looking to update the features?
If the TV is stuck on standby (Red light only) and will not turn on, or the screen is black (No Backlight/No Picture), the bootloader may be corrupt. This requires hardware tools.
Tools: A flash programmer tool (like the RT809H or CH341A) and an SOP8/ISP clip.
