Jessie is old enough that the graphical desktop was probably LXDE, not
LXQT.

Stretch is pretty old too. Current OS is based on Buster (Debian 10.x).

So DON'T overwrite (flash) the eMMC -- run an SD card image directly
until you verify that it does what you want. THEN convert the card to a
flasher to update the eMMC.

Note: depending upon just how old that Jessie image is, you may have to
use the boot-select button when applying power to the board. I believe it
was sometime late in the Jessie period that u-Boot was modified to
automatically switch to the SD card. Also take note of the fact that Jessie
is still in the "Linux kernel loads device tree overlays" -- for some time
now, it is u-boot that loads the overlays, so updating the eMMC by some
means that doesn't update the u-boot will cause problems.
