Lava V2 s stuck on company logo after deleting Launcher 3 and System UI I have rooted Lava V2 s running on Android 5.1 and mistakenly deleted some system apps: Launcher 3, and System UI. The phone is starting up but cannot go into the home screen. Instead, it directly goes to power off and has stuck on the company logo while booting up.

How to fix the boot issue?
