I have managed to download the update without restoring my 520. Now the update is ready to install but I'm afraid it'll brick the phone. I've heard many saying unsupported phones get bricked after installing Windows 10, especially Lumia 520s. So I was hoping in case I bricked my phone but have it fully backed up to OneDrive and restore it using Windows Phone Recovery Tool, will I lose my data? Coz I can't afford to lose anything in my phone. Pls help in this regard. Also is anyone facing any issues with the 520 on Windows 10?
