Re-downloading High Quality Images from iCloud

This forum software wouldn't let me edit my original post, or delete it, so I am creating a new one.

----

So apparently iOS decided to enable iCloud Photo backup without telling me.

Now it is giving me alerts that 667 photos "could not be downloaded in full original size" because I don't have enough space on my phone. Apparently iOS decided to set it to "download in low quality".

The problem is I dont use iCloud photos. I use Google Photos. And I want all my stuff on my phone in *original* high quality. But apparently iOS has taken all of that OFF my phone and put it into the cloud.

Now how do I get it?

I tried freeing up space. I don't believe it reacted by re-downloading everything.

I tried disabling iCloud. It threatened to delete all my photos off the phone (!!!) ***...

If I disable iCloud, let it delete my entire life, change the setting to "Download in Original Quality", then re-enable iCloud, will it put everything back on my phone in high quality? If not, how can I get all my images back on my phone. And in the future - apple - dont turn something on without asking me.
