I had some problems with the update. Two times I tried to install it from the App Manager, it downloaded it, then clicked continue to install, but then the device rebooted sw_rst. I was low on battery so I had the USB cable put in while installing.

When I tried without cable but then it said: not enough battery life to install update.

So then I just charged it for a while, disconnected the device and tried again. Third time it actually installed.
