I HAVE UPDATED MY FIRMWARE MANY TIMES BY CONNECTING WITH THE PC.
I HAVE ITS DRIVER ,PROGRAMS AND FIRMWARE ETC.
ONE DAY WHEN I WAS UPDATING THE FIRMWARE BY PRESSING TE KEY COMBINATION IT WAS DETECTED BY MY PC.
BUT WHILE UPDATING I HAVE DISCONNECTED FROM THE PC BECAUSE IT WAS TAKING LONG TIME.
SINCE THAT DAY I AM UNABLE TO CONNECT IT AGAIN TO MY PC.WHENEVER I CONNECT IT IS NOT RECOGNIZED BY MY PC.AT THAT TIME I WAS NOT AWARE THAT WHILE UPDATING FIRMWARE PLAYER SHOULD NOT DISCONNECT.
I HAVE SEARCH A LOT AND SOMEONE SAID TO SHORT CIRCUIT SOME PIN OF FLASH AND CONNECT IT AGAIN IT WILL BE DETECTED .
i have short circuited the pin 29 and 30 with an all pin but still it not recognized by pc. one thing more should i have to hold play button while short circuit or not when i have to connect. i have try both means hold and short circuit and short circuit alone bot none has work.
CAN ANYONE HELP ME WHICH PINS OF FLASH HAS TO SHORT CIRCUIT OR WHAT TO DO SO THAT IT CAN AGAIN DETECTED BY MY PC.
PLEASE HELP
THANKS |
