hello! I have a DM500s given by my friend. Now, i tried to flash the image, but the username:root and passwrod:dreambox is not right. I also tried to click the "RESTORE FACTORY SETTINGS" but there is a 4 digit passcode to get into that menu. is there any way that i can remove the passcode and uncover the username and password? I tried to use through FTP because i dont ahve the RS232 cable to connect to my PC. Please give me advise on what to do. Thank you very much for your help.
