Hi I am new to the forums but not rooting Droid devices. I am having a similar problem with my UI/touchwiz home crashing. I have a GS4 that I rooted about a month ago and I use Titanium backup Pro to backup and Freeze programs. Here is where I made my mistake using the ROM Toolbox Pro. I found a setting that would change the size of the Icons. It was set to 460 and it said default was 160. I changed it to 160 and now I am not able to get past the home screen. I already tried a factory reset with no luck. I have a question about adb. Do any of you think I would be able to change that setting back to default using adb on my PC. Or do any of you have any other suggestions on how to fix this? I am so pissed that I made a change without not fully understanding what I was doing.
