MyMPx.org - Screen blinks and only a white screen

last week i was with my sister and we plugged the mp4 to the dvd (just to test it) because we bought it recently... and when we tried to play the videos on the mp4 it didn't work.

Now when we try to play a video it says loading... and then it restarts! the problem is only on the VIDEO OPTION..Ive tried to fix it changing the firmware... i did a back up of the firmware with s1fwx i thought that it was ok.. i changed the firmware and the pc didnt recognize it it was like an usb device or something... I upgraded the driver again and restore the firmware that i backed up but it didnt work 100% it seems that s1fwx doesn't work for 9.0.5 version of firmwares.

Now is dead... the screen blinks every time i touch the menu button and its only a white screen. Ill try the DEAD PLAYER RECOVERY GUIDE but i've changed a lot the firmwares and I know that i have one that that works exacly like it was before..(working all the options except the video) if I can get to that, I should format the mp4???

I'm afraid of that because I read that maybe i can get a reduced part of my disk!. Its only 2 gb! :cry: I don't want to lose them! they are real because it has a lot of music and they are 2 gb for sure... well I Hope You understand my ENGlISH and you could help me (with the mp4 not the english) jeje bueno chauu saludossssss Y gRaCiAs THANKSSS
