About Custom RR: ROMs & Recovery
Custom RR is a reference app for people choosing custom Android software for a specific device. It catalogs ROMs, recovery environments, and Treble-compatible system images, and lets users select a phone so the listings can be filtered to builds that support it. Device pages show which projects officially support that hardware, while separate labels distinguish community-maintained ports from official builds. Entries can include descriptions, features, screenshots, device support, and links to the relevant project pages. The catalog marks discontinued projects and identifies older builds, with successor suggestions where available. Freshness indicators show whether a project is active, updated monthly, or discontinued, and warnings can highlight project-specific concerns before installation. The app includes step-by-step flashing guides and reference material for Treble device variants, architecture differences, and common installation issues. It works offline with a bundled catalog and refreshes information online at launch. Data for hundreds of devices and multiple ROM and recovery projects is included. Custom RR is a research and reference tool for Android modding, not an installer. Users still need to follow the instructions for their device and download the appropriate build separately. It distinguishes official support from community ports to help users understand the status of each listing.
