Fastbootd windows driver?

/e/OS Devices Teracube
1

I was able to run the installation instructions up until it reboots into fastbootd.

fastboot -w
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash vbmeta vbmeta.img
fastboot flash vbmeta_system vbmeta_system.img
fastboot flash vbmeta_vendor vbmeta_vendor.img
fastboot reboot fastboot   <---- breaks here
fastboot flash system system.img
fastboot flash product product.img
fastboot flash vendor vendor.img
fastboot reboot

At that point, fastboot commands no longer work and report “waiting for any device”.
It does show fastbootd on the phone, with the E logo on a white background.

Looks like Windows lacks the drivers for the 2e.

I have been unable to locate sufficient drivers that will make fastbootd operational.

Install the driver Download MediaTek USB VCOM Drivers (for MT65xx, MT67xx, and MT68xx Chipest)
Follow instructions from the default /E install (doc.e.foundation/devices/2e/install) till you get to the section below.

Run the following commands from fastboot:
fastboot -w
fastboot flash boot boot.img
fastboot flash recovery recovery_factory.img (This is the factory recovery, not the /E recovery)
fastboot flash vbmeta vbmeta.img
fastboot flash vbmeta_system vbmeta_system.img
fastboot flash vbmeta_vendor vbmeta_vendor.img
fastboot reboot fastboot

Install driver from [DRIVERS] Nexus 4 Driver for Windows | XDA Forums

Run the following commands from fastbootd:

fastboot reboot

Let the phone load into /E.
Enable USB debug, adb reboot bootloader

Run the following commands from fastboot:
fastboot flash recovery recovery.img

The interaction of this being a superpartition phone and still having the A & B slots makes for some weirdness.

I unzipped the ROM into j:\Android\test.

Then, I had to use:
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot erase userdata
fastboot erase metadata
fastboot flash gz_a j:\Android\test\gz.img
fastboot flash lk_a j:\Android\test\lk.img
fastboot flash md1img_a j:\Android\test\md1img.img
fastboot flash scp_a j:\Android\test\scp.img
fastboot flash spmfw_a J:\Android\test\spmfw.img
fastboot flash sspm_a j:\Android\test\sspm.img
fastboot flash tee_a j:\Android\test\tee.img
fastboot flash boot_a j:\Android\test\boot.img
fastboot flash dtb_a j:\Android\test\dtb.img
fastboot flash dtbo_a j:\Android\test\dtbo.img
fastboot flash vbmeta_a j:\Android\test\vbmeta.img
fastboot flash preloader_a j:\Android\test\preloader.img
fastboot flash ramdisk_a j:\Android\test\ramdisk.img
fastboot flash ramdisk-recovery_a j:\Android\test\ramdisk-recovery.img
fastboot flash super j:\Android\test\super.img
fastboot --set-active=a
fastboot -w reboot

Note the ‘_a’ bits above.

With the release of 1.1-q for the 2e, the instructions at Install /e/ on a Teracube Teracube 2e (2020) - “2e” work flawlessly!
