USB Installation & Flashing Instructions

Follow our standard verified technician protocol to prepare the USB flash drive and safely flash this TV:

Format a USB flash drive (8GB or 16GB USB 2.0 recommended) to FAT32 with MBR partition scheme.
Extract the downloaded firmware archive (.zip or .rar). Locate the target firmware installation file (.bin, .pkg, .img, or update.zip / CtvUpgrade.bin / allupgrade_*.bin) and copy or move it directly to the root directory of the USB drive (do not put it inside any subfolder).
Turn off the television and disconnect the AC power cord from the wall outlet for at least 60 seconds.
Insert the USB flash drive into the USB 2.0 port on the television chassis.
Press and hold the physical power button on the TV panel, then reconnect the power cord.
Keep holding the power button until the standby LED begins flashing rapidly or the software upgrading screen appears.
DO NOT disconnect power or unplug the USB drive during upgrading. Wait for progress to reach 100% and the TV will reboot automatically. When the welcome screen appears, pair your remote control and complete initial setup.
