      What is Gzosp

Ground Zero ROMs, the ROM development team that brought the US the popular custom ROMs Tesla, Tipsy, and Validus, has provided a central android oreo repository from that custom ROMs is designed while not having to begin from scratch (meaning straight from AOSP).

The concept of the bottom Zero Open source Project (GZOSP) is to convey custom ROM builders a much better place to begin with each the mandatory AOSP code and also the CAF (Code Aurora Forum, Qualcomm’s own repository that is helpful for non-Nexus devices with flower SoCs) code to make for a large form of devices.

It shouldn’t be confused with the popular ROMs Tesla, Tipsy, and Validus as a result of it contains none of the options that create those ROMs distinctive. consequently, once you build from this repository, the team requests that you just don’t complete your ROM as AN unofficial Tesla, Tipsy, or Validus build till they’ve free the first official version for public consumption.


This is the 1st Build we will update changlog time after time 
if there is any new build after this.

  1. Great Work. Back-2-Back Oreo ROM Release By Santoni DEVs… Cant believe they are doing all these without source code. Hope Eveyone will respect there hard work… As much I do. Thanks Again For Oreo Experience Sir. 😉 More Power To you.

    • Gzosp based on aosp and it have no customization it give you pure stock feel in other rom like aex etc have many customizations, every rom have there unique identity brother

      • It’s a good ROM, really. Just wanted to know how to change a color accent to the blue of the Pixels and activate the round icons in the settings, I tried to decompile the APK but fell into bootloop, however it is not a deterrent
