Sailfish OS pinephone

I tried to install SFOS on a PinePhone 1.2 (community edition) using this script:

https://github.com/sailfish-on-dontbeevil/flash-it/blob/master/flash-it.sh

However, this script fails to download https://gitlab.com/pine64-org/crust-meta/-/jobs/artifacts/master/raw/u-boot-sunxi-with-spl-pinephone.bin?job=build. (It’s a 404.)

Am I using an outdated version of that script? Or am I going about this all wrong?

Bonus question: I’d like to install straight to the eMMC. Is that aforementioned flash-it.sh script suitable for that purpose?
