Libsamsung-ipc already has a tool to compute the checksum of the EFS nv_data.bin files, so we can change their content.

The idea would be to write a tool to restore the EFS.

As the EFS is usually printed under the battery, users would lookup the EFS there and would give that to the tool.

Some XDA threads have probably the information for various devices.

It would be interesting to have information for any of the devices that are or could be supported by libsamsung-ipc, so if anyone has links to that it would be nice to post it here.
