Caution: Before you proceed, do keep in mind that installing this update could void your warranty and the biggest caveat being that you cannot roll back to v8 if you wish to. I’m guessing you could rollback by flashing your phone with the stock firmware but we haven’t tried this method out yet. This XDA thread will give you detailed instructions on how to flash any Nokia Lumia device to the stock ROM.

Step 4 – Check for updates
Next, go to ‘Phone update’ in the Settings menu and click ‘Check for updates’. Before installing 8.1, your phone will most likely download the 8.0.10322.71 update. This is to just to prep the phone for 8.1. After a reboot, head to ‘Phone update’, check for updates once more. Now, the Windows Phone 8.1 update will download and install automatically.
