You cannot tell which hash algorithm was used for key derivation. This only works if you have a copy of the exact same volume, and if you haven't changed the password since the backup copy was taken. If you do happen to have an older copy of the volume somewhere, you should be able to just take the first 512 bytes of that backup and write it over the first 512 bytes of the corrupted volume. the volume mounts successfully but you can't read the disk, but if you can't get it to mount then unfortunately you are out of luck without a volume header backup. Tools like TestCrypt can help you if the volume will decrypt but the filesystem inside is corrupted, i.e. There is no secondary copy of the volume header within the volume itself - this would break the deniability property of the volume by providing distinguishability. Even if you have the correct password, you cannot recover the data without an intact header.

There are unofficial Android and iOS apps, none official. Once unlocked in this state, you can do whatever you want with the folder. Those 512 bytes contain the information necessary to build the volume encryption keys that are used to encrypt/decrypt the data. Once you unlock and mount the encrypted file, the folder will show up in the root directory of the virtual drive Veracrypt creates to allow you to access the files. If the first 512 bytes of the volume are corrupted, the only way to recover is with a backup of the volume header. If you're certain you're entering the right password, but VeraCrypt is saying 'incorrect password or not a volume', it's likely that you have a corrupted volume header.
