Use a high-quality USB pen drive (8GB or 16GB is usually sufficient) and format it to FAT32 .

Move the extracted firmware file (e.g., allupgrade_ms638_4G_1G.bin ) to the root directory of the USB drive. Do not put it inside any folders. 3. Installation Guide (Flashing)

Place all downloaded RAR parts in the same folder on your computer.

Right-click on Part 1 and select "Extract Here." The extraction tool (like WinRAR or 7-Zip) will automatically pull data from the subsequent parts (including part03) to recreate the single original firmware file, which is typically a .bin or .img file. 2. Preparing the USB Drive

You cannot open part03.rar alone. You must download part01.rar , part02.rar , and all other numbered parts in the sequence. These files are often hosted on technician forums or specialized sites like Advance Electronics Butwal .

If your TV is stuck on the logo or has software issues, follow these steps to flash the firmware: Turn off the TV and unplug it from the wall.

The TV will reboot automatically once the process reaches 100%. Unplug the USB drive immediately after it reboots.

Press and hold the Power Button on the TV (not the remote) while plugging the power cord back into the outlet.
