I've got a Vortex CORE that I never really use due to it being a fairly impractical keyboard but I pulled it out the other day when I found myself having very limited desk space.
The first problem I noticed was when I typed Shift+Fn1+B I didn't get an apostrophe and instead got a "<".
Not being able to figure it out I thought I'd just reset the layer using Fn+R however after holding down for 5 seconds (even tried 30 seconds) nothing happened. Next I tried resetting the whole board by holding both Alt keys and again nothing happened.
Then I thought screw it I'll update the firmware but when I open the update software it doesn't show the current firmware version and OK is greyed out. I've tried on 3 different computers with 3 different microUSB cables and still no luck.
I think I updated the firmware to V1.04.05 in 2019 but I'm not entirely sure.
This is the exactly keycap layout of my CORE
