Galaxy Ace duos GT-s6802


Jul 17, 2013
I have a Samsung Galaxy ace GT-S6820. When i tried to install jellybean update through from the sd card after rebooting in recovery mode and wiped date, cache, dalvik cache,
and battery stats. then selected install zip from sd card and picked cyanogen mod. then after it says installing update. it says:

installing update... assert failed: getprop("ro.product.device") == "cooper" II getprop("") == "cooper" II getprop("ro.product.board")
== "cooper" II getprop("ro.product.device") == "GT-S5830" II getprop("ro.product.board") ==
""GT-S5830" E:Error in /sdcard/ (Status 7) installation aborted.

This is my first time attempting to root/flash so i am probably doing something wrong as the device name is appearing as GT-s5830 instead of GT-s6802.

Please help
