This is my favorite mistake
Did this also at the very beginning
No - thats not correct...
You need to extract the files INCLUSIVE folder "InstallSamygo"...
In root the must be folder "InstallSamygo" and inside this the files (and other folders)....
According to your Drive setup - This is correct:
I suggest to make again a clean try:
Format USB stick
Extract all to stick leaving the Folder as it is (F:InstallSamygo - And inside of this folder... the files - This is how the archive comes actually)
Reset Smart HUB on TV to Default and Reboot to TV once
Then again the procedure as described in first post.
