Decrypt LG multimedia files without the pin
Made with the following references:
All that you need to decrypt *.dm files is your email address used when they were encrypted. This is usually the same email that you're signed in with on your LG device.
If the email address provided is incorrect, the resulting files might not contain data or might be invalid.
dmcrypt <email> <inputs...> -o <output_dir> [-r]
Note: The output directory will be created if it doesn't already exist.
