Installing e/OS on CMF Nothing Phone 1 - A15

My CMF Nothing Phone 1 is on A15. I tried using the easy installer, but it just sat there for hours and never installed anything. Has anyone successfully installed the official manually or with the easy installer with A15? I’m not sure whether I should proceed, downgrade to A14 (not comfortable doing), or just wait for the official A15 release. I did see one user mention that an official A15 could take years. Thanks!

you will find guidance there :
