Recovery: Mstarupgradebin
If the MBoot is intact but the kernel/rootfs is corrupted:
If the USB method fails entirely, the bootloader is severely damaged. Professionals use:
This method requires disassembly and technical skill. It is not recommended for general users.
If you have UART access but standard flash fails:
MStar# nand erase 0x200000 0x2000000
MStar# fatload usb 0 0x82000000 MstarUpgrade.bin
MStar# nand write 0x82000000 0x200000 0x800000
MStar# reset
(Addresses are examples – always dump existing partitions first with nand info.)
The glowing red LED was the first sign of trouble. Mark’s smart TV, the centerpiece of his living room, was stuck in a relentless "boot loop." Every few seconds, the manufacturer's logo would flash, fade to black, and then mockingly reappear.
Mark knew that standard resets wouldn't work; his device's firmware was corrupted. After hours of scouring forums like Reddit, he discovered the solution: he needed a specific recovery file named MstarUpgrade.bin. The Quest for the Binary
The file was more than just data; it was a comprehensive firmware installation script and payload designed to repartition and flash the TV's eMMC memory. Mark finally tracked down the correct version for his specific MStar processor. He carefully formatted a USB drive to FAT32—a crucial step—and renamed the file exactly to MstarUpgrade.bin to ensure the TV's bootloader would recognize it. The Recovery Ritual
With the TV unplugged, Mark inserted the drive into the side port. He held down the physical power button on the frame—the "secret handshake" to trigger the manual update—and plugged the power cord back in.
For a tense moment, nothing happened. Then, the screen flickered. Instead of the logo loop, a blue progress bar appeared: "Software Upgrading." The script was working, decompressing the payload and overwriting the corrupted partitions. Back from the Brink
Ten minutes later, the TV restarted one last time. The setup screen appeared, crisp and clear. By manually using the MstarUpgrade.bin recovery method, Mark had bypassed the manufacturer's expensive repair service and brought his dead tech back to life. kogan-tv-gpl/MstarUpgrade.md at master - GitHub
To recover or update your device using the MstarUpgrade.bin file, you need to perform a "forced upgrade" via USB. This process is commonly used to fix boot loops or black screens on smart TVs, projectors, and Android boxes using MStar chipsets. Prerequisites USB Drive: Use a 4GB to 32GB drive. Format: The USB must be formatted to FAT32.
File Placement: Place the MstarUpgrade.bin file directly in the root directory (not inside any folder) of the USB drive. Recovery Procedure
The exact button combination varies by brand (like Hisense, Philips, or ViewSonic), but the general steps are:
Prepare the Device: Turn off the physical power switch or unplug the device from the wall.
Insert USB: Plug the USB drive into a USB 2.0 port (usually the one labeled "Media" or colored black). Trigger the Upgrade:
Method A (Reset Button): Press and hold the small RESET button (usually with a pin) while plugging in or switching on the power. Keep holding it until a progress bar appears.
Method B (Key Combination): Hold down the Power button on the physical panel (not the remote) or the Input button while switching on the power rocker.
Wait for Completion: A blue screen or progress bar will typically show the percentage. Do not power off the device during this time; it usually takes 5–10 minutes to complete and reboot automatically. Troubleshooting Tips
File Naming: If the upgrade doesn't start, ensure the file is named exactly MstarUpgrade.bin. Some devices may require it to be renamed to Forcedupgrade_001.bin.
USB Port: If one port fails, try another. Older MStar devices often only recognize the update file from a specific USB 2.0 port.
Drive Recognition: Some screens are picky about USB brands. If it doesn't detect the file, try a different, older USB 2.0 drive. "Booting" no image on screen!!!! - Zidoo forum

The MstarUpgrade.bin file is a firmware binary used to recover or update televisions and monitors utilizing Mstar chipsets (common in brands like Kogan, TCL, and various Android TV boxes). When a device is stuck on a boot logo or trapped in a loop, this file is used for a forced firmware update to overwrite corrupted system partitions. 1. Preparation
Identify Correct Firmware: You must use the exact MstarUpgrade.bin for your specific model and product code (located on the back of the TV). Installing the wrong version can permanently brick the device.
Format USB Drive: Use a USB stick that is 16GB or smaller, formatted to FAT32.
File Placement: Copy the MstarUpgrade.bin file directly to the root directory of the USB drive (do not put it in a folder). Ensure there are no other files on the drive. 2. Forced Recovery Procedure
While specific key combinations vary by brand, the general "forced" method follows these steps:
Power Down: Hard power off the TV using the physical rocker switch or by unplugging the power adapter.
Insert USB: Plug the prepared USB drive into the Media USB slot.
Trigger Recovery: Press and hold the designated physical button on the TV itself (not the remote) while reconnecting power or turning the rocker switch on. Common trigger buttons include:
Power Button: Hold or tap continuously until a blue screen appears. Input Button: Keep it pressed during power-on.
Right Arrow / Middle Button: Hold until the standby LED begins blinking. This method requires disassembly and technical skill
Wait for Install: A screen should appear showing "Upgrade in Progress" or a blue installation screen. This process typically takes 5–10 minutes. Do not power off the device during this time.
Auto-Reboot: The TV will usually restart automatically once finished. 3. Post-Recovery Steps
Factory Reset: It is highly recommended to perform a factory reset from the settings menu once the TV boots up to clear any residual corrupted data.
Verification: Check the firmware version in Settings > About to confirm the update was successful. Alternative: Android Recovery Menu
If the TV can reach the recovery menu but not the home screen, you can sometimes trigger an update or wipe from there:
The MstarUpgrade.bin file is both a lifeline and a potential trap for embedded devices. With the right preparation – a properly formatted USB drive, the exact firmware, and knowledge of your device’s recovery key combo – most brick scenarios are reversible.

Last updated: 2025 – Covers MStar chips from MSD6A628 to MSD938. Recovery methods vary slightly by supplier, but the core principles remain.
Creating a MstarUpgrade.bin file for recovery typically involves repackaging firmware images into a single binary that the MStar bootloader (MBOOT) can execute. This process is common for reviving "bricked" Smart TVs or Android-based projectors using a USB drive. 1. Structure of a MstarUpgrade.bin A standard MStar binary consists of two main parts:
Firmware Installation Script: A plain-text script (often called header_script) that tells the TV's bootloader how to partition the eMMC flash and where to write the data.
Payload: The actual raw images (e.g., mboot.bin, boot.img, recovery.img, system.img) that will be flashed. 2. Tools for Development
To "develop" or build this piece of firmware, you can use specialized scripts that automate the padding and CRC (cyclic redundancy check) calculations:
mstar-bin-tool: The most popular open-source utility for unpacking and packing MStar binaries.
aescrypt2: Used for older or specific builds to encrypt or decrypt the recovery.img if the device has Secure Boot enabled. 3. Creating the Recovery Binary
If you are building a custom recovery piece, follow these general steps:
Extract Original Firmware: Use mstar-bin-tool to unpack an existing MstarUpgrade.bin to get the base header_script and partition layout.
Modify Recovery Image: Replace the default recovery.img with your modified version. Ensure it matches the architecture (usually ARM) of the MStar chipset.
Update Script: If your new image size has changed, update the mmc write.p hex values in the installation script to reflect the new byte lengths.
Pack the Binary: Run the packing script (e.g., python mstar-bin-tool.py --pack) to combine the script and images into a final MstarUpgrade.bin. 4. Executing the Recovery To use the piece you developed to recover a device: Format: Use a FAT32 formatted USB drive. Placement: Place MstarUpgrade.bin in the root directory.
Trigger: Insert the drive and perform a "forced update." This usually involves holding a physical button (like INPUT, VOL+, or RESET) while toggling the main power switch.
