Hi,
In following link You have description and two programs with description (unfortunately in Russian).
In short You need to insert MMC in external USB card reader (important: do not format S7-MMC card). Start S7imgRD.exe to read image.
Afterward start Unlocks7200and300.exe to unlock S7 program from image file created with S7imgRD.exe.

As far as I remember, this does not work on new versions. Or am I wrong?

I THINK SO, BUT I AM USING IT ON AN OLD PLC
