Topic: I can't use 3rd party filament with my Davinci miniMaker !! HELP!!

Hello,

I have a Davinci miniMaker in my workshop. I was using orijinal filament, so someone upgraded the firmware without giving a thought. I want to use 3rd party filament now, I downgraded the firmware and bought some NTAGS. I write the NTAGS by android phone as instructed, 200meters. But always having the 'cartridge 1 can not found error:0028'. I tried almost everything I could find and understand. I shortwired the motherboard and installed various versions of atmel dumps, again no luck. I tried 1.0.0, 1.0.3, 1.0.5, 1.1.1, 1.1.5, 1.2.0, 1.2.3 versions. Also most of the time it shows 9999 meters of filament but it doesnt print.

What can I do? Can you please help?
