[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] m4nu4l:
Okay, i tried this ZTE Skate rom, i want to note that this device build prop was nearly identical and was easiest to try to port, as u suggested i didnt touched META-INF folders, but still i'm stuck in a bootloop

EDIT: Now i have tried with changing libs, Device is stuck on LG logo and Pacman boot animation dont even show up.

EDIT2: Tried also with set perms on META-INF folder, stuck on LG logo.

Here's a LOGCAT from the first build, w/o META-INF folder and libs. Any comments ?
