CETUS MK3 touchscreen issue

Cetus Cetus 1st Gen MK1-MK3
1

hi

I have Cetus MK3 Standard version. I’ve installed the touch screen upgrade:

  1. replaced CPU board with the one provided with the kit

  2. connected touchscreen to the main board

At this point everything including touch screen worked fine, but I’ve found out in the UPstudio that my printer is recognized as extended version.

So I’ve flashed the rom file “Cetus S7NTC_R_180524 MK3-STD.ROM” for the standard MK3 version. After flashing and rebooting the printer, the touch screen doesn’t work anymore (black screen). I can still use my printer with UPstudio.

What should I do to make the touchscreen work again ?
