If you cannot find a working 40-ms801a-mac2hg firmware file, consider these options before recycling the TV:
After downloading, compute the MD5 checksum (using tools like certutil -hashfile on Windows or md5sum on Linux). Ask in forums for the correct hash before flashing.
In the world of consumer electronics repair, few things are as cryptic—and as critical—as the firmware string on a TV mainboard. For technicians and advanced hobbyists, encountering a silkscreen label like 40-MS801A-MAC2HG often triggers a mix of recognition and frustration. This article unpacks what this code means, where it comes from, and how to approach firmware management for this specific hardware revision.
We're releasing a firmware update for the 40-ms801a-mac2hg device to improve stability and add a few quality-of-life fixes. Please read before updating.
First, let’s break down the identifier:
In essence, 40-MS801A-MAC2HG is not just a firmware version—it is a hardware + software fingerprint.
Most MS801 boards have a dedicated USB port labeled "SERVICE" or "USB 5V 1A" . The process is: 40-ms801a-mac2hg firmware
Warning: Do not interrupt power during flashing. A corrupted bootloader requires an SPI programmer (e.g., CH341A) to recover.
The code 40-MS801A-MAC2HG refers to a specific printed circuit board (PCB) assembly—the main logic board of a television. Let’s break down the nomenclature:
If you open your TV and see "40-MS801A-MAC2HG" silkscreened near the main processor or printed on a barcode sticker, you have identified the exact board requiring firmware.

These boards usually utilize eMMC or SPI Flash memory; firmware files are often provided as dumps for programmers or files for USB recovery. Update and Recovery Methods
Depending on the state of your TV, use one of the following methods: Standard Network Update (If TV boots): Navigate to Device Preferences System Update Network Update After downloading, compute the MD5 checksum (using tools
to check for official OTA (Over-the-Air) updates from TCL/Thomson servers. USB Forced Update (For Boot Loops): Format a USB drive to Place the firmware file (often named Update.pkg or similar) into the root directory.
Unplug the TV, insert the USB, and then plug the TV back in while holding the physical Power button on the TV panel.
Release the button once the "Software Upgrading" progress bar appears. Direct Firmware Dump (Technical Repair):
If the eMMC or Flash chip is corrupted, a full memory dump must be flashed using a programmer (like RT809H or UFPI). Specialized repair communities like KenotronTV Forum-Monitor host these technician-level files. Service Menu Codes
