4.0.1 running smooth and sweet as always
Flashed from 3.2.1 to 4.0.1 with no wipe. No errors or problems so far.
I just changed my build.prop using this to show the correct model as Nexus 5X.
After the reboot, the model is shown correctly, 5X, and the Google Assistant is still working. Rebooted a second time and the model is still correct and GA still works....
I just flashed the latest Purity rom and it looks great. No problems for me with this procedure:
Used TWRP to reboot into recovery
Flash New Rom
Rebooted and all looked fine
Booted into Recovery and flashed SuperSU and GAPP...
I know this post is a bit old...but a good solution for this issue is Best Wifi:
Do you have a WiFi extender in your home or office, or even a second WiFi Access Point Name (APN)? You do? Then ‘Best WiFi’ is for you!
And they said Google Assistant still worked? I don't know. I didn't see that.
The wifi hotspot could be an AT&T issue. I don't get any warnings or issues with it on T-Mobile.
That was me saying that. It worked for a day then Google Assistant...
