To "unroot" the device and get rid of the exclamation mark, use Odin and flaah stock kernel. I did that myself and was able to restore original Galaxy S 2 splash screen (and kept root). Remember, in order to use Odin, you must first put the phone in download mode by simultaneously pressing and holding volume up and down amd power buttons. If you need more assistance, feel free to PM me. Good Luck.
