Why do you want a link for a rom that can't be installed?!
They uploaded the MiNotePro ROM, and then removed it because it was faulty (The installation failed, and the attempt causes for wifi failure afterwards).
If you tried to install the update to MIUI 8 and it failed - the attempt is causing the Wifi to be disabled.
Just re-install the previous version (6.5.26), and the wifi will be fixed.
Mi Note Pro - developers version.
Tried to update (without wipe) and the update seems to have failed. After restart the phone remained at the pervious version (May 26), but the Wifi isn't working.
I re-installed the May 26 version.
