So I'm currently using Samsung Galaxy S2 (for the next two months cause my phone is broken so til i can afford the galaxy s6), it runs on android 4.1.2 so i tried to update it and it starts downloading android 4.2.2 and when it's done it asks me if i wanna install it so i press yes then a message comes on the screen that says "note
hone will be rooted" so i press ok and then it starts installing and a green android guy appears then it stops on 24% and the android guy dies and my phone restarts and says "updating firmware failed try updating using kies" so i tried updating using kies and it stops on 69% and doesn't move at all so yeah is there another way to update my system or is there a solution to the problem,Note: I tried updating both ways many times and still nothing I even factory reset the phone still nothing , Thank you.
