 Download [[https://github.com/3DSGuy/Project_CTR/releases|ctrtool]] and run <code>ctrtool --intype=cci --verify dump.3ds > ctrtool_log.txt</code>(replace dump.3ds with the name of your dump). This will create a file called ctrtool_log.txt, which you should keep alongside the dump. Download [[https://github.com/3DSGuy/Project_CTR/releases|ctrtool]] and run <code>ctrtool --intype=cci --verify dump.3ds > ctrtool_log.txt</code>(replace dump.3ds with the name of your dump).
