The Anniversary Update for Windows 10 Mobile is finally here, after the PC versions was released. However, not everyone is able to grab the update immediately, mostly because Microsoft decided to release it gradually, but also because of various installation errors.

So, if you actually received the update, but are unable to download on your Lumia phone it for some reason, we’re going to show you a few solutions for your problem

Solution 1 – Plug in your device

Windows 10 Mobile is programmed to to make sure that once you start downloading a new update, nothing interrupts it. Therefore, if you don’t have enough battery to download and install the whole update, your device simply won’t let you download it.

So, the solution for this is pretty obvious, you just need to plug in your phone to a charger, and try to download the update once again. If you’re still not able to download the Anniversary Update, even though your phone is plugged in, or your battery is full, try some of the solutions listed below.

Solution 2 – Make sure you’re connected to WiFi

Similarly to the previous case, you’re phone probably won’t let you download the Anniversary Update, or any other update for Windows 10 Mobile if you’re using data connection. Windows 10 Mobile does this to prevent huge data charges, because updates like the Anniversary Update are quite big, and they can eat a lot of data, and even cause some additional charges if not connected to WiFi.
