Hi ,

I have to backup fdl files to create a .pac file of my spreadtrum sc8825 phone. i need it to be done without any volcanobox, avatarbox etc.
is there any means or software to backup these file from phone with any special hardware.
OR is this files are related to specific hardware combination or we can use any sc8825 fdl files.
