Error installing windows phone recovery tool

[antonio1701]

I updated my Lumia 535 to Windows 10, but since I wasn't all that satisfied with W10 I decided to restore W8.1.
First I did a factory reset, but after that it just did a clean install of W10, not W8.1.
Then I tried Windows Device Recovery Tool, but when I try to reinstall the software I get a message saying that there was an error downloading the software package, and that downloading the file RM1089_02074.00000.15234.28007_RETAIL_prod_signed_1054_025F5A_000-33_MV.ffu failed.
I tried the process on multiple computers. It starts downloading, downloads cca 89KB and displays the error message.
What can I do to restore my phone to W8.1?
W10 looks really nice, but it's still really laggy and tons of apps and settings are not working for me so there's no use in using it just yet.

Did you use several different networks, firewall setting etc.

I am sorry to say this but the fact that you though that a hard reset would revert your phone back to 8.1 leads me to believe that you did not do a proper research before you updated your phone to WP10. Furthermore if you installed and tested the WDRT before you updated you also would not have this problem now.

Anyhow I hope you can revert back to WP8.1.

This method worked for me for those who are having the hash fail error, try this uninstall any winusb drivers from control panel uninstall a program, then download any new updates for windows and office and install them, then download the installer again for windows device recovery tool and run the installer as administrator wait for the winusb drivers to install takes a while and then setup will continue installing Windows device recovery tool.
