Greetings and welcome, roxyparu,
Firmware is essential to a TV being able to run correctly! Thank you for reaching out to us for some advice on your 50-inch. We’d be happy to point you in the correct direction.
Can you please give Toshiba a call at (855) 527-2411? They’d be best positioned to direct you further with this model of TV. Upon reviewing the material available on Toshiba’s website, it doesn’t appear that firmware may be available to download and upload via a USB drive to the TV. Additionally, since this is a SMART enabled device the firmware should download and install automatically if it’s connected to Wi-Fi. It’s our sincere hope the dedicated teams at that number above will be able to assist you further.
