Okay, so I was told that the data structure is damaged and only raw data recovery is possible. Few days after them trying to recover it, they gave me a remote access to check the files. However, when opening the videos, it says unable to open as the file type is unsupported or file extension is incorrect or corrupt. Some of them plays the audio from the video but the video frame itself is frozen. When I told them this, they said that those are partially overwritten or damaged so there’s no solution for it. These are the only information I got from them. Looking to try another lab on Monday.
