Hi friend, did you flash the certification patch?Hi Darth thanks for the update, I successfully installed it on my phone, I'm still having Device not Certified on my GPlay app, I came from CrDroid Rom, and decided to switch to Havoc, though I followed the exact procedure on Havoc installation
Finally managed to flash Magisk on Havoc 4.1 with the help of youtuberking (telegram and YouTube).
Hi, Havoc is Alive now stays on 4.5 version really smooth and the battery drains is excellent see the OPHavoc GSI based in Android 11 is almost dead, heard that developer who was maintaining this Rom had left the group.
I have tried many other GSI roms and thencame back to Havoc 3.12,,,,, seems like I got addicted to Havoc.
