Hi K3 users 
I wanted to create something and tried to make my first rom, based on the latest stable 1604 ST VIBE 3.0 Android 5.1 stock image.
Here comes my rom: Betty Rom v1:
K3 Note – Betty Rom v1
Features:
- Heavily debloated – missing most unused apps – only about 440MB in size
- Rooted
- Comes with Busybox
- Comes with init.d support
- Comes with Gapps
- Comes with Dolby Atmos
Feel free to try out my rom.
Installation:
Wipe in TRWP (you could try a dirty flash, but i do not recommend this) and install the rom. No need for flashing additional Gapps or supersu.
Let it boot for several minutes, will take a while!
Messed up icons on home-screen? –> After having booted, press menu button on home screen, go to options in lenovo launcher, goto data, press restore from local –> will correctly arrange the icons on the android home screen.
This is my first try to build a rom, i am not responsible if anything goes wrong, if you brick your phone, if my rom renders your setup unusable and so on. I have successfully tested it on my K3 Note, but i do not garantuee that it works for you.
Already have a few ideas for version 2 in my mind
