When I try to "Install" from the pulley menu (after the update is downloaded), the phone just seems to switch off and nothing happens. I've waited more than 30 minutes, still nothing. I've tried while connected to power and also on battery (80%) only. When I finally wanted to reboot because nothing happened, I got a red persistent LED the first time (had to remove the battery for it to turn off and finally reboot the phone). The second time, on battery, the LED just stayed a few seconds and then I could reboot normally. After both reboots, the phone was in flight mode. Settings say I use only 8 GB out of 13.75, so I guess it should be sufficient, right?

What am I missing?

[Edit] It seems to be working (at least I have the "Sailfish" update screen) now that I did that. Not sure if it is what solved the issue though.
