Snag It, Flash It, Ship It: Rethinking Factory Flashing With Open Tools
summary
Open-source factory flasher expanded from Snagboot into snagfactory (v2.0, Nov 2024) with a Windows GUI, parallelized flashing and saved per-session logs. Recovery uses snagrecover to load U-Boot into RAM; flashing uses snagflash with DFU/fastboot and automatic chunking for images larger than RAM. It supports seven released SoC families (Broadcom merged, Rockchip and Raspberry Pi incoming), writes GPT and eMMC hardware partitions, and runs OEM U-Boot commands. Limitations: USB/U-Boot dependency, no hot-plug batch addition yet, and DFU speed constraints.
