Google Pixel 3 - Cannot Stop Security Updates I just recently got the new pixel 3 and have loved the phone from stem to stern but I have this huge issue with it. Since I turned it on and ported all my contacts, photos, etc over it has not loaded all my apps. I found out this was because it has been installing system security updates non-stop for over 24 hours now, rendering it basically useless.

I can't use this phone in this state. I've tried clearing the google app cache and storage and it keeps on chugging through security update to security update. I can't even tell how many it has completed or has yet to do because it has no indication of how many are left, at all. All I can see is the current update's progress. I've had to reboot the phone twice this morning just for the security updates.

Is there a way via rooting the Pixel 3 or entering developer mode, or just some setting i overlooked that I can tell the system to stop updating so I can have a useable phone? Or am I up a creek.
Unfortunately this this the proper way to initialize a newly bought Android device.

Google usually releases every month a new security update and each security update has to be installed individually, and often after the update installation a restart is required. 

Hence if you get a device that for example was produced 6 months before you have to install up to 6 updates one at a time.

In this case the Pixel 3 has been released in October 2018. If the device you got was produced at that time up to the time of the question up to 8 updates have accumulated and each update has to installed one-by-one plus reboot. 
Hence the first hours after switching on a new Android device you are busy installing security updates, which usually requires several buttons to be pressed at the correct time.
