Having read so many praises about Huawei's EMUI (Emotion UI) I decided just to try it on my Ascend P1. I thought it was like completely new ROM but it's just a launcher that, I believe tried to borrow from MIUI, and it's a joke. Nothing beats MIUI! So I went back to MIUI and to my suprise I found Facebook and Twitter apps still there. They are stuck in data/cust/app folder and I can't uninstall them or remove them in any way. Not with root explorer nor with any root uninstaller. I confirmed that I am rooted because I can delete files in other system folders and uninstall other system apps. So, two questions: 1. Doesn't system partition get wiped when I fresh install MIUI? 2. Anyone can tell me how to remove those two apps? Thanks in advance.
