How to get the necessary files from the "damaged" dmg image?

Question

Backup

In general, the story is this .... I wanted to put Windows on a macbook through bootcamp.
Naturally, when choosing the BOOTCAMP partition, I started to write an error (something was wrong with the layout of the hard disk) and "after the holidays", I instead deleted all other volumes (except OS X) with it. Windows installation failed. OS X stopped loading.
Through cmd + R, I went to the recovery wizard, there I selected disk utility and created an image with OS X on an external drive ~ 200 GB (I chose compressed type). It took a very long time to create this image. After I repartitioned the entire hard, installed os x from scratch. Can't open dmg image.
I tried to open:
- with the usual double click (mount) . Gives the error "No mounted filesystems"
- restore to a hard disk partition. I don't remember the error. But it was about failed to check the source and the error of the argument.
- converted from "compressed" to "read/write". The same thing, only the weight of the image has become more by 40 gigs.
- 7z archiver. With extract, one file was obtained with large cracks without any extension .
I have tried many utilities to recover data after I formatted the entire hard drive. (The whole area of ​​free memory is in zeros). Why it completely cleared it is not clear to me.
But I looked at the image itself through a hex editor and there seems to be some data there.
The question is, how do you get them?

Answer 1

Have you tried DiskWarrior?
Or convert to .img?
Or mount with all sorts of different options?

hdiutil attach -nomount -noverify -noautofsck -ignorebadchecksums image.dmg
