Downgrading eS/gS-Series MFD software from LightHouse 3 to LightHouse II
Before updating to LightHouse 3, eS/gS-Series MFD owners are strongly advised to review the information and FAQs addressing the differences between LightHouse II and LightHouse 3 found here to ensure that LightHouse 3 software will meet their current needs. Should one upgrade an eS/gS-Series MFD(s) to LightHouse 3 and afterwards determine that they would prefer to run LightHouse II software within their eS/gS-Series MFD(s), then it would be necessary to downgrade the software within the eS/gS-Series MFD(s) to LightHouse 3 v3.3.170 prior to downgrading the software with the eS/gS-Series MFD(s) to LightHouse II v19.03. These downgrades may only be performed via a microSD card which has been updated with the corresponding software. When downgrading from LH3 v3.3.170 to LHII v19.03, the MFD will be switched OFF, the microSD card containing the LHII v19.03 files will be inserted into the MFD's memory card reader, and then the MFD will be switched ON ... the MFD will then automatically proceed with the software downgrade.
