Question No Firmware found for EG4 FlexBOSS LCD Screen

Currently running an EG4 FlexBoss 21 with added LCD screen. This has the problem where it does not display any current data in all data fields. Including the home page and others like Device info button. I'm running a longer ribbon cable but currently don't think this is the cause. I was looking for any LCD firmware associated with FlexBoss 21 and the added LCD screen. I have looked in your FlexBoss 21 area but don't see anything related to LCD firmware. There also does not appear to be any information specific to the LCD display in any of EG4's web pages. I see the following information under Device info of the LCD - Firmware version - XX1.0, Build Version - EAA-0000, LCD version 12, Icon version - 18, Model - 00000000, Serial number - XX1.0. Maybe some of this information is not being populated from the FlexBoss. I do see a firmware version for the 18KPV - (18kPV LCD Version 25 Firmware). Should I try that? If there is no firmware update, and is should be working, then maybe the issue I'm seeing is related to my longer cable (~3 Ft). If there is an update, please point me to the path so I can try.
