Hi, I am faced Problem with My JXD921 PMP. I recently Purchased. I Burned Direct Aimg , Bimg and firmware. to my device. Once Succefull installed I reset and restarted. I can Figure only Green Light on the player not LCD Light or Glow only total Blank screen. I think the Firmware install it not right.
So I tried Using again FRM but FRM unable to detect any device. whearas as soon i connect on System my computer shows 2 removable drives one 1 GB (internal Flash memory) an other 2 GB my SD flash Kingston card.
I have a secure backup of my Orignal firmware. But unable to put it back. drivers of my PMP is SPCA5000 all things are prefect but I would like to know the way to boot my Device and detect it to FRM there after i can re burn my old Firmware which works. So please help me.
On internet I have heard if such problem occurs due to wrong firmware either we need to open and short circut an IC pin. or We need to please combination of Secret Button to detect the device to System than open FRM and load the Firmware.
PLease Help me.
