# UniDump: an opensource Unisoc/Spreadtrum phone flash reader # UniDump: an opensource Unisoc/Spreadtrum phone flash reader
## About
Cross-platform MediaTek feature phone dumping had been achieved long ago with [MTreader](https://gitlab.com/suborg/mtreader). Now it's time to do the same for Unisoc (ex-Spreadtrum) phones.
Unfortunately, the architecture of Unisoc chipset boot ROM doesn't allow us to get away without any loader blobs. So, some FDL binaries are also shipped in this repo.
The `unidump.py` is the main file to use. The `unicmd.py` is the library created for easier command interface encapsulation.
