Unable to open DMG files - "Corrupt Image"

I created a DMG file using Disk utility in Recovery Mode (File -> New Image -> Image from Folder).

I tried all the possible options from this question:

• extracting DMG using 7Zip - not working
• converting it to another format like ISO - not converting
• opening DMG using Disk Drill - not opening
• opening DMG using Data Rescue - not opening

Is there any way to extract the data from the corrupted DMG file?

Found this online. Here is the link: How to repair a corrupted sparse bundle/image or dmg file

Here are the commands:

hdiutil attach -nomount -noverify -noautofsck -readwrite /volumes/"name of your image"
fsck_hfs -drfy /dev/diskxsx (x is your disk number)
hdiutil detach /dev/diskxsx (x is your disk number)
