Have you tried with the computer in SAFE mode? Worth a shot.UPDATE
I successfully upgraded the firmware using a USB-to-RS232 cable I purchased from Radio Shack - the Gigaware 6ft. USB-A to Serial Cable, #26-949. Laptop is a HP Pavilion dv2313 running Vista 32. My laptop does not have a RS232 port (not much does these days). So I decide to give this a try.
After installing the drivers that came with the cable, I attached the cable to the projector and then to a USB slot. THEN, open up the Device Manager, look for an Item called Ports
. You should see the USB-A to Serial Cable item. Double click
In the Advanced tab, select a free COMM port to use (I used 3). Then per the Planar users manual, set it to 38400 bps, no parity, 8 data bits, 1 stop bit, no flow control. Save and close the Device Manager.
Make sure you have extracted all ZIP items from the firmware download into a folder. Double click the application and proceed per instructions.
Also, the instruction pdf shows a time of about 00:44 on the page where it says the process is complete. It actually took mine close to 15 mins, so be patient. As long as the process dots keep moving, you are making progress.
Hope this helps.
