I have just bought Nokia Lumia 900, and everything works and looks very well. But the phone won´t update its firmware (current version is the factory preset of 2175.2101.8779.12201).
ZUNE update procedure keeps bombarding me with 80070424 error. Already tried restarts (both computer and phone), antivirus / firewall settings, and different wifi networks available for connection. Please advise.
Take a look at this article form MS for the exact error code you have. Hope this helps
