Thank you for your post and assistance, I have tried it and it does not work. Will stop posting. Apologise for all the inconvenience cause.

I just came up with a step by step guide on how to the upgrade using the Updater tool.
Download here:
Upgrading to MIUI 8 with Updater Tool
Give it a try. I really think your not working issue is with the Charging mode vs File Transfer mode.
It's just a pdf file and no risk of any malware.
Others who have the same issue with upgrading to MIUI 8, I used these exact steps to upgrade 3 phones with no issue at all.
Give it a try and let me know if it need to be improved.
