Devicer

Devicer

    

Unified Windows toolkit for managing rooted Android phones — identify, search ROMs, back up, patch, and flash from one shell.

Status

v1.2.0 — in-app ROM download. The ROMs tab now downloads builds directly into %LOCALAPPDATA%\Devicer\roms\<codename>\ with chunked HTTP + SHA256/MD5 verification, resume support, progress bar, and cancel. Previously the "Download" button opened the browser; it now saves to disk and verifies the hash against the ROM source's published digest. A "Browser" button is still available for users who prefer the browser workflow. Seven functional sidebar pages (Device / Firmware / ROMs / Backup / Patch / Flash / Universal) plus Settings. See CHANGELOG.md. Tooling-landscape document at docs/research.md, phased build plan at ROADMAP.md.

Goals

1. Identify device + currently-installed ROM (model, CSC, build fingerprint, BL, baseband, root status, slot, encryption state).
2. Search & download stock firmware (Samsung CSC-aware) AND custom ROMs (LineageOS, crDroid, PixelExperience indices) from one search box.
3. Back up — partitions, EFS/NV (Samsung-critical, losing it bricks IMEI), userdata, Magisk modules.
4. 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.

Why

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.

Stack (locked v0.2.0)

C# / .NET 10 WPF, TFM net10.0-windows10.0.22621.0, MVVM via CommunityToolkit.Mvvm. Catppuccin Mocha theme.

Architecture (locked v0.2.0)

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.
