Lg leon (h320)

GM!

Issue:
Would like to get LG H320 LEON rootet and want to install CustomRom (CYANOGENMOD 12.1)

Problem:
- OneClick-Root runs up till 65% then manually putting into Downloadmode -> COMPORT 6 -> no success
- Kingo (only found chinese version) running, running, then I will have KingoRoot on phone but LEON not rootet -> not working either

Question:
- how to root properly -> tutorial needed
- how to get bootloader opened -> tutorial needed
- how to get CYANOGENMOD 12.1 installed

Thanks for your support,
