I hate blink feed. I removed it from my home screen(s) almost immediately upon getting my M8.
That being said, do NOT freeze or uninstall it with Titanium backup. No way to boot up the phone after that one. At least for my device.
Brave. Thanks for being the guinea pig!
I can also verify that this works after latest OTA backup.
At least I am not the only one paranoid about this kind of thing. LOL
Never mind. The poster above me answered it for you.
Install Titanium backup and kill the update service. I think it is "Software Updates"
Then you won't have this problem. At least I don't.
