Thanks for your reply. Yes, I ran the hack file and installed the 505 bios but it only goes into the menu and then automatically pops up the firmware upgrader the first time the usb is disconnected after a full format of the main drive. A quick format doesn't work. I have formatted the drive many times and chkdisked it too while trying to flash the proper 300 firmware.
Would it be relatively safe for me to use command prompt to recreate the master partition record using diskpart and see if that fixes that particular problem?
The 300 firmware I am using is the one called 'Uninstaller 300.zip' from the prsplus google code site.
