First of all i would like to thank @erfanoabdi for providing the GSI and providing fixes
Also I'd Thank @abhayruparel for helping me flash this GSI

1) First Of all Your Internal Storage Will be wiped out so backup important data

2) U need to be in Non Treble TWRP Download Link

3) Then Decrypt First by formatting data partition (Go to Wipe ---- Format Data)

Note :Decryption is an important step do not skip it!!

4) Reboot to recovery

5) Change Data partition to f2fs

Note :- If at any point TWRP gives error message like failed to format or mount /data , reboot to recovery

6) Change data partition to ext4

7) Wipe System, Data, Internal Storage, Cache, Dalvik Cache

8) Now reboot to recovery even if u are on recovery

9) Now Flash Treble TWRP by mike Download Link

10) Reboot to recovery again (Mandatory)

11) Now flash los 15.1 Official only no other zip Download Link

Please do not boot into the ROM because it automatically encrypts and all your previous efforts will be in vain!!!

12) Now wipe System, data, cache, internal Storage

13) Now Flash Android P semi 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

14) Reboot to twrp again This is mandatory

15 Now go to mount and check all the Checkboxes, mounting vendor is mandatory

16) Then Flash Post Zip 1 = Download Link

17) Then Flash Post Zip 2 = Download Link

18) Then Flash Post Zip 3 = Download Link

19) Then Flash Incall fix zip is not needed in Developer Preview 4 !!

20) Then Flash p lag fix zip Download Link

21) Treble Magisk = Download Link



Now Reboot to rom and viola U will have android P gsi boot on ur P2!!!

Hi @gamefreaksuraj i have read somewhere that it has calling bug where you can't heard the voice. It is true?
And what about the substratum, does it work? I really liked the swift black theme.
Can we use it as a daily driver?
