ok here goes. I have an LG L45c (LG Optimus Net) i deleted a system app (homescreen tips) that i thought was stupid but i made a backup with titanium. i was running low on internal storage so i did a factory reset without restoring the app. Everything works out great except one thing, titanium backup is now saying it doesnt support my device and i seem to keep get my ota from factory reset though im not sure. because i used to have to go through ota every time i factory reset. the app sounds like protips.apk from some search but im unsure. i tried installing protips.apk from a 4shared link but came up 'application not installed' i can successfully root or unroot my phone at anytime what can i do?
