it's wrond that thing with the tweezers of the nand chip. you may BURN the chip if you short circuit the vcc+ pin with others. you must be careful to short ONLY 4 pins of the chip not random. i have a pic i found on the net i will upload it later. it works for these 4 pins as many times as you wish. also if you get an writing to flash error try to short circuit just for a secont -or- disconnect the li-on from the mp3 player for a while to cause the time function of the chip to reset. i noticed that there is a time function on some chips that prevents you from continuous flashing them. tell me if this works for you too.
