GrapheneOS as base layer

[ypid]

I am interested in using https://github.com/hashbang/aosp-build to build GrapheneOS. I think this makes a great base to work on HashbangOS specific goals. This means that https://github.com/hashbang/aosp-build could be used to automate and help audit (using reproducible builds and possibly additional helpers) the solid work that GrapheneOS devs are doing.

Current status: WIP. Using hashbang/aosp-build#31 I successfully built GrapheneOS and tested on the Pixel 3a.

Closes: #41

Edit: @sempervictus do you already have build scripts ready? If not, here are some. Ref: GrapheneOS/os-issue-tracker#408

@ypid Hi

I am also interested to use GrapheneOS as base for this Os.

Any progress from your side please?

Thank you

I already got it works. I just have not merged the PR because I need to change the logos because this is not GrapheneOS anymore.

@ypid So, it's not based on GrapheneOS any more? What is the difference between your actual version and GrapheneOS?

Does the security, encryption etc. of GrapheneOS still exists or you used another alternative?

Thank you

It is based on GrapheneOS, but HashbangMobile has additional change like setting up its own OTA updates and so on. I try to preserve all hardening work from GrapheneOS. That is why I base on it in the first place :)

When a PL is expected? looking forward to test it.

PL = public launch? For now, I just maintain the project for my own use for the Pixel 3a. I don’t dedicate much time into it. My idea is this: More substantial work will be done when a new Android version comes out. This includes merging the open PRs. The other months, I run this project on maintenance only basically. If other contributors want to help with the project goals, this thing could fly. But with only me it is not realistic right now.

Sorry, I mean PR (Pull Request), can you share your progress? Will try to install it and contribute in the limit of my knowledge.

• Switch to GrapheneOS based on Android 12.1 #49
• Android 11 and Debian 10 base image aosp-build#31

Any documentation to build and flash it to mobile?

Thank you

Only what you find in those repos that I linked. You will need to figure that out by yourself. That is also probably the best way to learn. Try it, and only ask questions if you spend a considerable amount of time wrapping your head around it.
