Before the official jb update was released, I installed a leaked version. Here's my phone info:

Now, my phone says there's an update available for 4.1.2 but the phone reboots and says update failed. I am not on stock 4.1.1 . It's been months since I used Odin or flashed anything so could I just please get a little help here? Thanks
