problem galaxy s ll
This is my first time posting on the forum, I'm quite desperate for help.
So, my S2 has had a lot of problems recently with crashing and turning off etc, so I decided to do the reset. I navigated through settings and selected 'erase everything'. I'm sitting here, over 12 hours later, with my phone still displaying 'Unmounting USB storage' and I have no idea what to do. If this is normal and I just need to wait it out then that's fine, I'm just worried something has gone wrong.
