Simon, I edited because I realized how did you downgrade and it was not the same way I did. I updated directly to version which I wanted, which was 04.45.25 but you updated to stock then later update you wanted trough USB. I did downgrade my TV but not the way you did and encounter few problems on the way, otherwise I would not post. If you would understood how programs work you would understood my way. And btw your way of downgrade, is not your way, so do not copy and edit update tools filename like _by Simon, because you did not create these programs neither did tutorial. So next time you snatch someones work, think about it.
