Here is a script to extracting all files from your A2 phone!
Run a2uploader,then press "..." by MISC files,insert the
Script file and press "Write Script".
Now connect your phone by pressing "C" Button,or "2+5" Button!
A2 uploader now read the files and copied them to the a2uploader
folder in the folder named "ph out".
Thats all and FS backup is created with all drivers and files
NB: Thanks to gani for this!
