unplug black 5 pin tft cable (is only used for touch mode. checking to see if perhaps you have it plugged in backwards, which keeps the controller in reset, ie not starting up)

TFT cable isn't used at all

#

Checked it also by trying it in all possible connections, doesn't work at all

next guess is its not flashing new firmware correctly, it is quite picky about what sd cards it will read from. Have you tried more that the one sdcard and was it freshly formatted?

#

config looks fine

Jup. I tried 2 different SD cards and also all possible slots in the touchscreen (SD/usb

it has to go into the motherboard sd slot

#

does it rename the firmware.bin to firmware.cur?
