Soooo, I rooted my phone a while ago (galaxy s4 i337 build mk2 4.3) to erase all the bloatware and stuff.
I decided to unroot it using titanium backup because my phone was starting to slow down, even after moving off all pictures/music (what was taking up the most storage).
When i unrooted it, it was still slow and the update wouldn't go past 27%, so i was stuck on 4.3.
A few days ago I tried to flash the stock firmware using Odin and lost 4g data/any type of network data but still can connect to wifi and call/text.
ps I used a post from androidrootz, and since I am a new member, I am unable to post that link in this post.
Does anyone have any idea what could have caused that/what i could do to fix it?
