Samsung Galaxy Ace 2 i8160 stuck on the boot screen.

Hi all. I know there are quite a few posts with people having a similar problem to this, however none of the solutions mentioned have worked for me. Recently, I updated my phone to JB using Odin 1.85 (I8160XXNF1). All was working fine, and when i recieved a notification saying there was an update available, I updated to a new version, which was also JB 4.1.2 but it changed to I8160XXMG2. Everything still worked fine at this point, though there was still an update available. So, once again, I decided to update it although this time the phone never fully booted, it gets stuck on the boot screen every time (the one saying 'SAMSUNG galaxy Ace 2 GT-I8160' not the animation). I couldn't boot into recovery, only into download mode so I flashed the previous JB (I8160XXNF1) which worked, however this has not resolved the problem and the phone is still stuck on the same screen.

Okay, thanks for reading this, please help if you have any ideas on how to resolve this issue.
