I wanted to upgrade Marlin with files given by geeetech. I installed CH340 driver, started Firware Tool from geeetech, drop .hex file, click on upload local while holding reset, Nothing happened but now I have a blue screen on my printer and impossible to print something... :x

:D Hi, If your printer can upload firmware normally,
No need to press the reset button while uploading;
You can try the firmware again.
Then check if your wiring is loose and tighten the screen wiring.
Can your printer print via USB connection to a computer?
