Two days ago while watching the TV the message for an update popped up.
I accepted and it started installing the update. When it finished the TV restarted but it never passed through the black screen with the TCL logo.

​

I remained like that for about 1 hour. Then I unplugged it and plugged it back but the same issue remained.

​

I have tried several different "fix" methods but none of them have worked so far.

Also, this tv does not come with a dedicated reset button in the back.

​

Only thing that I think could work is to somehow install a previous software/firmware version through a USB, but I can't seem to find it anywhere. I called technical support and the only thing they could do was to try to connect me with a technician.

​

Has anyone here had this problem when updating your OS?

​

Thank you
