How forth32/balongflash works
balongflash is a command-line utility for flashing Huawei Balong V7 modems and LTE routers. The documented workflow accepts BIN/EXE firmware or component files from a directory, supports extraction and signed or unsigned images, and flashes in download mode. The sampled partition code confirms partition discovery and zlib decompression; source-index references identify the main program’s dependencies, but do not show its call sequence, so uncertain internal links are dashed.
