The install script is capable of changing Android version so I don’t think this will be the blocker. Please check one or two posts with hashtag eosinstaller … there is no documented way to collect a log of what went wrong so probably easier to revert to manual cli install page Install /e/OS on a Nothing Nothing CMF Phone 1 - “tetris”.
There is also [HOWTO] a Clear Guide to install "IMG-e-builds" when /e/ web installer fails
So no real harm done as the method is to install the fastboot ROM denoted by “IMG-e build”
