I'm sure I've seen a response from the startosinstall command alluding to something like that in the past. I seem to recall in the past that attempting to 'downgrade' from the recovery boot of one version of macOS (e.g. Has anyone successfully installed Mojave using a startosinstall command from a Catalina recovery (or Internet Recovery) boot? I'm seeing the same symptoms of it just hanging at 'Preparing to run macOS Installer.' It does not sound like your issuee was like mine but I thought I would share this here. 'ДЄpple sent me this solution and it worked on one and I am running through the other:

In other words, you need to use Configurator so that we can custom-build and install firmware that will be specific to your system and yours alone - this customized system-specific firmware is what was destroyed when the drive was formatted, and what will need to be replaced in order for you to reinstall the operating system. The firmware on T2 equipped systems is uniquely customized on a per-computer basis. This is due to how the T2 chip and secure boot firmware function, and because formatting the HD wipes the firmware that is not just hardware-specific. Here is Apple support explanation: ' T2-equipped systems like MacBook Air 2018 require Configurator 2 and a 2nd T2-equipped system in order to reinstall the firmware and operating system once the HD has been formatted. The reason was b/c we erased the firmware when support formated the system with disk utility. The laptops would act like they were building and then loop back into recovery. For me on 2 MacBook Airs the recovery would not work at all.

I reached out to Apple support we are fortunate to have enterprise and I received this on how to fix it. Try a wired keyboard, built-in Recovery, a different startup disk, or bootable installer.I found out about the T2 devices after erasing and rebuilding on an older system, pre-firmware boot laptop that did originally ship with High Sierra. If you cannot startup in Recovery Mode by using this startup combination, the current version of macOS may be too old, the internet connection may be faulty/insufficient, or the keyboard may be faulty. This will install the version of macOS that came on the device from the factory (or the closest version still supported) Key Combination: Shift + Option + Command + R Internet Recovery (installs original macOS version) This will install the latest compatible macOS version on the device. Supported on devices from Mid 2012 and newer (as well as some older models with firmware updates, information here). Internet Recovery (installs latest compatible macOS) Open Terminal from Recovery Partition (reset user password, disable/enable SIP, change date, etc.).Add or remove an EFI password (must know password if removing).

Use Disk Utility to partition, repair, erase, format drives.

Things you can do in Internet Recovery Mode:

Note: Internet Recovery only works if the Macbook has OS X 10.12.4 or later installed due to a BootROM update Note: It is advised to be wired to Ethernet for this mode. Note: Internet Recovery Mode takes longer to boot - this is normal. This covers the start up mode using the Option + Command + R or the Shift + Option + Command + R keys.
