t8sg v2 plus Blanc screen after firmware update

My Jumper carbon does not accept that firmware. Steps I take:
1. I put usb mode and format the memory of the T8sg
2. I start it in Dfuse mode and with the program I install the .dfu file
3. I put Usb mode and pass to memory the 11 elements, except the .dfu file and .zip file
I have to have some internal problem

And now it puts me sometime: Missing Modules CYRF6936

I've been through the exact same scenario.. 3 days of hacking around and got it working, with V2 LCD, inc. voice. Now I realised that I was conned into paying more for the "Carbon" - main reason: brighter OLED screen like the regular "Yellow" V2 Plus, as I have poor sight - old age and all. So it turned out that the screen on the "Carbon" is the same quality as my original T8, only slightly bigger.... I did look at a few youtubes of some of the Carbons with OLED... I must have got a "DUD version".. or is it just the firmware problem?

¿Where can I get the file V2 LCD inc. voice.?

My carbon has a super bright OLED, but I have seen some carbons with an old looking LCD... I think they ran out of screens and started puting cheaper lcds
