The following article describes for Juniper Networks QFX5100 Series Switches software versions, how to move revert from a “QFX 5e Series” image to “QFX 5 Series” image

You upgraded by mistake to a 5e version but want to revert to a 5 version.

If you remove a QFX5100 switch from a QFX5110 Virtual Chassis or VCF and want to revert the QFX5100 switch to a “QFX 5 Series” software image to run as a standalone switch, you need to reinstall the image on the switch using a USB boot device with a “qfx-5-” install media file that does not use the secure-boot method.
