I have a big problem with my Letcool.
I upgraded firmware with custom firmware (2.2) through FRM but when I restart the system with power button, I see a white screen without menu or sound
I retryed with all the firmware (2.0, 2.1, 2.2), FRM recognized USB devices but I have always the same white screen.
Do you know a way to save my letcool?
In 2.2 firmware file I find a text with a procedure to restart system but nothing (push button for a lot of time...).
Many thanks in advance
