Custom RR
The single home for popular Android custom ROMs, custom recoveries, root solutions, and Treble GSIs. Curates 18 actively maintained ROMs, 5 recoveries, and 500+ devices, sourced live from the LineageOS wiki and the PixelOS official_devices repo and refreshed nightly by GitHub Actions. Material 3, zero tracking, no Play Services, GPL-3.0.
Whether you are flashing your first custom ROM or juggling a drawer of test devices, Custom RR keeps the whole Android modding workflow in one place: find a build for your exact phone, see how recently it shipped, read the flashing notes, and jump straight to the maintainer's official download. It spans LineageOS, GrapheneOS and crDroid through TWRP and OrangeFox recoveries, Magisk and KernelSU root, and Treble GSIs, with no XDA thread-digging required. It works fully offline with a bundled catalog, then refreshes from GitHub at launch so new ROMs and devices appear without an app update.

Frequently asked questions
What is Custom RR?
Custom RR is a free, open-source Android app and desktop tool that acts as a single hub for custom ROMs, custom recoveries, root solutions, and Treble GSIs. It lists official download links, screenshots, freshness signals, and flashing notes for 500+ devices.
Is Custom RR free and open source?
Yes. Custom RR is released under the GPL-3.0 license with full source on GitHub. There are no ads, no tracking, and no Google Play Services.
Do I need root or an unlocked bootloader to use Custom RR?
No. Custom RR is a browser and catalog, so the app itself needs neither root nor an unlocked bootloader. You only need those if you choose to flash a ROM, recovery, or root solution it links to.
Which devices and ROMs does Custom RR support?
Custom RR covers 500+ devices and 18 actively maintained ROMs, including LineageOS, crDroid, PixelOS, Evolution X, DerpFest, GrapheneOS, and CalyxOS. Device data is sourced live from the LineageOS wiki and the PixelOS official_devices repo and refreshed nightly.
What is the difference between a custom ROM and a custom recovery?
A custom ROM such as LineageOS or crDroid replaces your phone's operating system. A custom recovery such as TWRP or OrangeFox is the environment you boot into to flash ROMs, take backups, and wipe data. Custom RR lists both.
How do I install a custom ROM?
Installing a custom ROM generally means unlocking your bootloader, flashing a custom recovery, then flashing the ROM build for your exact device, but the precise steps differ from phone to phone. Custom RR pulls the right ROM, official downloads, and per-device flashing notes into one place. Install Custom RR and follow the in-app guide, or grab the complete, beginner-friendly in-depth flashing guide for the full step-by-step walkthrough.
How do I install a custom recovery?
Installing a custom recovery such as TWRP or OrangeFox usually means unlocking your bootloader and flashing the recovery image over fastboot, though the exact image and commands depend on your device. Custom RR lists the right recovery for your phone with direct downloads and the notes you need. Install Custom RR and open the recovery for your device, or get the full walkthrough in the in-depth flashing guide.
How do I root my Android phone?
Rooting normally means flashing a root solution like Magisk, KernelSU, or APatch, often by patching and flashing your boot image, but the method varies by device and ROM. Custom RR's Root section gathers every supported solution with official sources and guidance. Install Custom RR and open the Root section, or follow the complete, beginner-friendly steps in the in-depth flashing guide.
Which root solutions does Custom RR cover?
Custom RR has a dedicated root section covering Magisk, KernelSU, KernelSU Next, APatch, and SukiSU Ultra, each with live release dates and links to the official source.
Does Custom RR work on Windows, macOS, and Linux?
Yes. Alongside Android, Custom RR ships native Windows, macOS (Apple Silicon and Intel), and Linux desktop builds from the same Flutter source, with the same catalog and features.
Does Custom RR collect data or show ads?
No. Custom RR has zero tracking, zero ads, and no Google Play Services. It only fetches the public ROM catalog and GitHub release data; everything else stays on your device.
Can you root GrapheneOS with KernelSU or Magisk?
No. GrapheneOS intentionally does not support root solutions like KernelSU, KernelSU Next, or Magisk; it keeps the locked-bootloader, verified-boot security model intact and recommends against rooting. If you specifically need root, Custom RR lists ROMs that do support it (such as LineageOS or crDroid) alongside root solutions like Magisk and KernelSU in its Root section.
Is RR (Resurrection Remix) still maintained?
Resurrection Remix (RR) is one of the classic custom ROMs, but the original project has been discontinued for years. Custom RR flags it in its defunct section with a last-build date and points you to actively maintained alternatives such as crDroid, Evolution X, and DerpFest.
DerpFest vs crDroid: which custom ROM should I choose?
Both are popular AOSP-based custom ROMs focused on customization. crDroid is known for an especially deep set of tuning options and wide device support, while DerpFest offers a similar feature-rich, close-to-AOSP experience. The most practical deciding factor is which one is actively maintained for your exact device, which Custom RR shows via supported-device lists and last-build freshness so you can compare at a glance.

Custom RR is free, open source, and ad-free. If it saved you time before a flash, you can help keep it maintained:
