Try and reflash a rom, try Cacko ROM 1.20, extract the three files onto a FRESHLY FORMATTED compact flash card, follow the instructions, I tend to remove the battery for 30 seconds, you must make sure you repartition to 26MB, after it reboots and you get the sharp logo, remove the battery again and repeat the process, install the new ROM and ensure you format the user flash area, after that reboot you should get the OS up, it takes a while to load. It will say \'Wait\' and count down 5 to 1..
