Hi Custom AOSP ROM projects usually fail when device trees, vendor blobs, and kernel changes aren’t aligned, leading to bootloops, broken radios, or unstable OTAs. I can build and customize a production-ready AOSP-based ROM with clean device trees, properly integrated kernel sources, and reproducible build pipelines. I’ll remove Google services fully (GMS, Play dependencies) and replace required components with open alternatives while preserving core system functionality. For security hardening, I can apply SELinux policy tuning, permission tightening, attack-surface reduction, and verified boot–friendly changes without sacrificing stability. I’ll handle kernel-level modifications, vendor partition compatibility, and Samsung-specific quirks to ensure hardware features remain reliable. OTA updates will be integrated with signed builds and versioned releases so devices can update safely without manual reflashing. The result will be a stable, maintainable ROM suitable for long-term use and future device support. Thanks, Hercules

I am comfortable modifying device trees, integrating proprietary blobs correctly, managing SELinux policies, and debugging boot and stability issues across Samsung class hardware. For your project, I would focus on: - Clean AOSP build setup for the target Galaxy device - De-Googling and removing Play services dependencies safely - Security hardening at OS and framework layers - Kernel level adjustments where needed for stability and performance - OTA update integration and versioned release workflow I can deliver a reproducible build environment, documented patches, and a stable ROM image ready for deployment and future updates. I am available to start immediately and work with you in a structured milestone based process. Best Alex

Hello I’ve worked with AOSP directly and understand what it takes to build and maintain a custom ROM for real devices, not just in theory. I’m comfortable setting up the full AOSP build environment, modifying system-level code, and making device-specific fixes so the ROM stays stable and usable. I’ve handled things like removing Google services cleanly, applying security and privacy changes, working with device trees and kernels, and fixing issues that come up during builds or testing. I also have experience making ROMs update-friendly so future changes don’t break users’ devices. Before starting, I’d just like to understand: -Which devices you want to support first -Which Android version you’re targeting -Whether you want a fully de-Googled system or something like microG I’m happy to share details of similar AOSP/ROM work I’ve done and get started right away.

Hi - this is real AOSP work, not a surface-level Android customization. Custom ROM projects usually fail when changes are made without respecting the device boundary between AOSP, vendor blobs and kernel. You can remove Google services and harden the system, but if SELinux, power management or radio interfaces are touched carelessly, stability suffers in subtle ways. I ve worked on AOSP-based builds where the focus was clean separation -> minimal framework changes, device-specific logic isolated in the tree, kernel tweaks applied conservatively and OTA handled in a way that does not brick devices in the field. Security hardening should be incremental and testable, not a one-shot patch set. The goal is a ROM that behaves predictably day after day, not just one that flashes successfully. If this direction aligns, we can discuss in detail in chat.
