AI: Can you tell us what recovery methods you've already tried, like using a USB stick with firmware, button combinations, or accessing any service menus?
Tried unplugging it, then holding power button; tried holding power button on remote; I tried plugging in USB with a part of files that I found here on this site but did not work.
AI: Do you know what firmware version was on your TV before the update got stuck, or do you have any info about the previous software?
I have no info, unfortunately.
