I'm trying to upgrade my N810 to the new OS, and using the Update Wizard says it'll take 466 minutes to download the update.

I've already downloaded the file (All 134Mb) to my PC using another source, which before you download it says it's a .bin file. When it's actually downloaded, it shows as a .php. The Wizard wants a .bin file for the update though!

Do I need to convert it with something, or is there some step I've not taken?
