Q or LOS 17.0 is not yet in the picture for /e/ as far as the development is concerned. May come up much later this later. We had not expected the Q to Pie revert should be an issue but unfortunately that seems to be the case now.
Will be adding a generic instruction to all users to revert to stock Pie before flashing /e/ Pie Also will add that they avoid any downgrades below Pie altogether as it tends to brick most devices.
