first of all i need to know that if we flashed mp5 player with wrong firmware can it still play music in some cases and not display anything.?
Here What i have encountered first off all nearly ALL useful buttons of my mp5 player were not moving menu items(IT WAS NOT IN LOCK MODE).So i flashed it with some wrong version of firmware so now its buttons are moving through the menu i cant see it but i can recognize it with its sound
and amazing thing its still playing audio and video files (by randomly pushing buttons i first played songs and then videos) so each and every button is working fine.BUT the screen is WHITE and shows nothing.SO WHAT IS HAPPENING HERE i think i might have short circuit the LCD or i think that LCD DRIVER is not supported in this firmware so i am really confused and amazed.SO THIS IS MY QUESTION TO ALL BIG BOSSES OF THIS FORUM "HAD You ENCOUNTERED SOMETHING LIKE THIS"
