DLPC350: Unable to flash the firmware onto LightCrafter 4500

Part Number: DLPC350

HI,

I recently tried to update the firmware on my Lightcrafter 4500. The flashing started. When I came back 30 mins later, I saw the GUI window was frozen and not responding. I forced closed the GUI window and attempted to flash again but I am not having any luck. Every time I try to flash the default firmware, the GUI gets frozen midway. I noticed it always freezes at 56% completion at "Erasing sector @ 0xF9120000". See attached screenshot. I tried using multiple different PCs, changing the USB cable, and using a different version of the firmware. I also tried the basic steps like disconnect power, close the GUI, and reconnect power. The GUI says "Connected" but I can't do any operations on the unit. Nothing resolves the issue. At the moment it am unable to use the DLP at all because of the failed attempts of flashing.
