Here is a custom page refresh options patch that I think will work on the Aura, but as I don't have an Aura, someone else will have to be the first to test it.
It should be safe, even if it doesn't work properly I think the worst that could happen is that the device crashes when you try to select an option from the menu and you'd need to reboot and re-apply the patches with this one disabled.
Firmware 3.18.0; paste into libnickel.so.1.0.0.patch
