I've registered for Windows Insider to get the latest Windows 10 Preview. I currently have Lumia 630 phone with Windows 8.1. Whenever I check the status of phone update download, it reaches up to 70% every time, but then it stops and shows the following error:
"Make sure you're connected to the Internet and try again. It's best to connect to Wi-Fi so you can avoid possible cellular data charges."
Error code: 801881d0
Although my Wi-Fi is working all time, it still shows this error. I've tried at least 7 times. How can I fix this?
