Default ReGain Root access [Guide]

Root access losted after installing stock/custom rom ? Or by flashing the old backup???
OK OK I know that because that's why you are here
Don't worry you don't have to reroot it again :thumbup:
Just do what I said below
Code:
 1 . I think the custom recovery will there (may be the cwm or twrp )
 2 . Download the RootGainer zip from here .
 3 . Flash it using the recovery and reboot your device
Now you are going to amaze
Note :- This zip will only replaces the su values ... Flashing this zip may or may not be cause brick . I am not gonna take any responsibilities . Just think what you are doing before flashing.
It works on my Galaxy S Duos and maybe work for yours (my processor is arm )
