I can confirm that T-FXPDEUC_0000 for UE55F8000 is ok. It works.

I will download and try F8000 firmware.

For libFWdowngrade root is needed. And I cannot root my TV.

I am also searching for 0000 firmware for my F8000. I think are identical.

Thank you!

Thank you. I think it is a good app.
My TV has AA59-00787A remote, but it works with the standard remote included in your program. The only thing that does not work is the background picture, but I can live whit that.

I think you should use a 1920x1080 picture to calibrate.
I have done the same thing with my F8000 and just had to use the same type of picture, but with Full HD resolution.

I have UE55F8000. Do you still need it?
