I previously rooted my phone, I believe with SuperSU.. and had titanium backup installed and was working properly.
I kept trying to check for the update to 4.3 and when tapping "software update" nothing happened.. just showed the blue background of me tapping it, and stayed on the 'about device' screen. I tried unrooting my device using "Full unroot" in SuperSU and restarted my device.. when I opened titanium backup it said my phone was unrooted and that titanium backup wouldn't work anymore. I then went to try and do the update again.. but it's still not working.
Any other steps I need to take so I can perform the update?
