XL, you'll need to reboot from the userspace fastbootd mode to the bootloader by
selecting <code>Reboot to bootloader</code> from the fastbootd menu using the volume
keys and the power button in order to continue the installation.</p>

<p>A majority of failed flashes tend to be caused by substandard USB connectors,
plugging in via hubs or bad cables which aren't properly up to the USB standard. The
scrollback from a failed flash will contain valuable diagnostic information which
is essential in knowing where and how the process went wrong.</p>
<p>Front I/O ports on desktop computer cases and USB 3.1 or USB C on many laptops
often aren't implement properly or are broken in subtle ways, which may cause flashing
to fail even a USB port that works for other peripherals. Older Linux kernels that
predate version 5 may have inadequate or patchwork support for USB C or USB 3. If you
are installing from a Linux distribution, ensure your distribution uses a modern
kernel.</p>
<p>Always use a high quality USB A to USB C cable with a rear USB port directly on your
motherboard, and never use a USB hub for flashing. <em>Never install from a virtual
machine;</em> USB passthrough in software emulation may be broken or inadequate and this
can cause the flashing to fail.</p>
