First Of all i would like to thank all the developers of Havoc OS for bringing Up a GSI of their Rom 
Below are the Steps
0) First of all perform a factory reset through TWRP
1) Flash Treble TWRP by mike Download Link
2) Now flash los 15.1 Official only no other zip Download Link
3) Now wipe System, data, cache, internal Storage
4) Now Flash Havoc Pie GSI in system (Remember the GSI file which you will download will be ".zip" file , extract it from PC and use the ".img file") GSI Link = Download Link
6) Reboot to twrp again This is mandatory
7) Now go to mount and check all the Checkboxes, mounting vendor is mandatory
8) Now Flash The GAPPS package from this link Only Download Link
9) Now flash this permissiver zip Download Link
10) Now Flash Treble Magisk = Download Link
11) Now Reboot to rom and viola U will have android P Havoc OS GSI boot on ur P2!!!
Note :Your Phone Will Restart Once Automatically before it boots into ROM, but dont worry it will boot after restart !!
Bugs that i found While Using this GSI (Kuntao Specific)
VOLTE works as reported by a user , i cannot test volte as i Dont Use Jio
FP Gestures
Camera mode switching (From rear to Front and Vice- Versa )takes 8 seconds
Ambient Display
I tested few camera's but Footej Camera is working (Maybe even more camera apps should work)
Video Calling has issues with whatsapp and imo
Also front camera does not work in twitter , instagram , snapchat
