I think my best option would be to downgrade to an older firmware. I’ve surfed around the forum and seen that I have to make a donation to gain access to the firmware archive.
I am happy to do this but making a donation seems not so easy as PayPal is not accepted anymore.
I have no Bitcoin account and nor do I wish to have one.
Is there any other way of gaining access to older firmwares?
Edit: nevermind. Managed to downgrade using the libfwdowngrade method. For those curious, the latest firmware for this model (F8500) has this bug that smart hub takes a good 20 seconds or so to come up after booting up, while the message "Please wait while smarthub is being updated" is displayed. Older firmware didn't have this problem. I downgraded to 1206.3 which is still available on samsung's website. That solves the problem.
I put the correct files in the USB drive but when I select Update on the TV it says that there are no "valid" update files available in the USB drive.
My TV model is F6400
Home Theater Model: Samsung HT-F4500/ZD
