    • If the dictionary is a newer module like E-A400 (released on 2010 in China) or E-B400 (released on 2011 in China) there is a password when you want to enter the MANUAL CHECK > SERVICE MENU. If it is an older module like E-SF300 (released on 2009 in China) there is no password when you want to enter the SERVICE MENU. The SERVICE MENU has tools that can backup the system file to the SD card. But now no one knows what the password is. Does anyone have any ideas about how to hacking the password?
