Something weird happened oddly
So I went to go lay down on my bed and I must of hit some sort of button combination because my Galaxy Mega SGH-I527 now shows the regular Galaxy Mega logo at bootup but now with a picture of lock that's unlocked and under it it says "CUSTOM". Can anyone tell me what this is? Possible I, weirdly enough unlocked the boot loader? I am rooted btw on 4.2.2.
