I found a way to break DRMs on e-books which needs ADE on Linux (.acsm extension). Tools : Wine (for Windows Programs), ADE 2.0.1, Calibre with DeDRM extension. Perfect
There's no way to do so without the (windows only) ADE binary, right?
Yes because the DeDRM extension needs an epub from ADE binary (this tool take the .acsm file and create the .epub file). If you have kindle books, it works too but unfortunately i don't have the detailed process
