Filename: Usually named allupgrade_553_2G_refxx.pkg or similar. How to Install (USB Method)

Format your USB drive: Use a 4GB or 8GB USB drive and format it to FAT32.

Copy the file: Place the firmware file (e.g., allupgrade_553_sos.pkg) directly into the root directory of the USB drive. Do not put it in a folder.

Plug and Play: With the TV's power cord unplugged, insert the USB drive into the TV's USB port.

Initiate Update: Plug the power cord into the wall. Most versions of this board will automatically detect the file and begin flashing (the indicator light will blink rapidly). tp.hv553.pc821 software download
