It might be the same link, but I don't think it's the same file. I downloaded the file from the link a couple of days ago, but after it was installed, the setup process still wanted to download updates.
I downloaded the file from the above link, connected the Kobo to my computer via USB cable, copied the file to the drive and powered off / on the Kobo.
The update completed, the setup process didn't required a download and I was able to complete the setup process successfully!
My Kobo Vox is no longer a brick !
