i dont know if it works, but teoreticaly it will work.
first download ADB files from atach adb.rar 140.34KB 21 downloads
unzip in c:/
run CMD with administrator rights
adb pull /system
in the adb folder we will have all files from /system folder.
now create a flashable zip and flash in stock recovery.
p.s. here is a .rar file with /system folder, DO NOT FLASH IT!! it is just archiv with system folder, you need to unpack it an repack with .zip extension, sign file and you can flash it.
