Question [Q] (Q) asus memo pad hd7 update error. need some files..

Hi there. Recently i downloaded and tryed to install oficial firmware update. Everytime it trys to update gives error about AWS.apk file.
After some search i found that asw.apk is asus web storage. I'vÍ uninstalled some system apps and asus web storage was one of them..
Could someone plz zip system/app folder and send it?
Is there a better way to do a full system restore?
Thx in advance
