updating old sony tv with a usb
your sony bravia kdl-55hxhx750 is running on version 1.2, and you want to upgrade to the latest version 2.120. since automatic updates aren't enabled, you downloaded the update file from a third-party source, extracted it, and inserted it into the usb drive. you're trying to connect the tv to the usb but aren't seeing any update options—only internet updates appear. I'm looking into whether this update is available and how to install it properly, as the website information seems unclear.
Visit Sony's official support site and enter your TV model (KDL-55HX750). Navigate to the specific support page for your device. Check the firmware update area on the page. Obtain the latest available firmware for your TV model.
Prepare the USB drive by formatting it in FAT32 using your computer or Mac. Open File Explorer (Windows) or Finder (Mac), right-click the USB drive, select Format, and choose FAT32. Transfer the downloaded firmware file from Sony’s website—usually a .zip archive. Locate the update folder inside the archive, such as PSV\UPDATE, and copy it to the USB drive’s root directory.
Insert the USB stick into your TV’s designated port and power it on. Access the update settings via the remote control (press Home). Navigate to Settings > Support > Software Update > Update via USB. If unavailable, use Settings > System Update or About > Software Update. Begin the installation process. Verify the firmware appears on the screen; if not, confirm the file’s placement matches the required structure. Ensure the firmware is from a reliable source before proceeding.
The issue is that Sony has stopped allowing the public to manually download updates, and I’m also unsure if my TV can handle downloading via USB.
They could continue to receive updates over-the-air (OTA) using an internet link. If not, you must reach out to Customer Support. Sony supports the new policy changes.
I linked it to an Ethernet port on the TV, but I can't reach anything online since it keeps crashing.
These might predate the ADPocalypse, perhaps? 2012 seems to be just before it resumed if I recall correctly.
