Unified Windows toolkit for managing rooted Android phones — identify, search ROMs, back up, patch, and flash from one shell.
v2.2.0 - workflow automation and local-build hygiene. The current alpha includes guided flashing, AVB/vbmeta-aware safety gates, payload.bin extraction, streaming Samsung firmware download/decrypt, debloat tooling, snackbar notifications, accessibility labels, localization scaffolding, and local-only release packaging. ROADMAP.md is drained; blocked hardware, signing, and strategy items live in Roadmap_Blocked.md. See CHANGELOG.md and docs/research.md.
- Identify device + currently-installed ROM (model, CSC, build fingerprint, BL, baseband, root status, slot, encryption state).
- Search & download stock firmware (Samsung CSC-aware) AND custom ROMs (LineageOS, crDroid, PixelExperience indices) from one search box.
- Back up — partitions, EFS/NV (Samsung-critical, losing it bricks IMEI), userdata, Magisk modules.
- Patch + flash — patch boot.img / init_boot.img with Magisk on the PC side (no phone roundtrip), flash via Odin protocol or fastboot, with EFS-clear and Knox-trip safety gates.
No single tool covers all four jobs in 2026. The closest existing option, Thor Flash Utility, only does firmware download + flash. ROM-search aggregation is still browser work. Backup orchestration from PC is fragmented across TWRP nandroids and per-app tools. Devicer integrates the recommended best-of-breed toolchain (Bifrost + Thor + tetherback + Magisk_patcher) under one shell.
C# / .NET 10 WPF, TFM net10.0-windows10.0.22621.0, MVVM via CommunityToolkit.Mvvm. Catppuccin Mocha theme.
Orchestration shell with subprocess wrappers for every backend tool. Devicer.App (WPF UI) sits on top of Devicer.Core (services + models). Each external tool — Bifrost, Thor, tetherback, Magisk_patcher — runs as a child process across the OS-level boundary, which keeps Thor's GPL-3.0 from contaminating Devicer's MIT license. Tools are downloaded lazily on first need to %LOCALAPPDATA%\Devicer\tools\ with version + SHA256 pinning.
