I've followed guide after guide and nobody on the Internet has gotten errors as simple as I have. I've managed to use gdisk to change the partition type to the APFS it is meant to be, but it still won't detect it.
However, I know all the actual data is perfectly intact, iBoySoft detects all 150gb of it within seconds - I just don't have that kind of monney and don't want to support that company.
Previously, I have been able to recover APFS data by a gdisk correction - that is not the case this time. I have learned a valuable lesson in APFS, though, that it is the only filesystem where you can't move the left anchor :)
Any help would be greatly appreciated. I have a total of about 3 files I want off the old drive (which now is left-anchored to the BEGINNING of my SSD ;))
Partiton trying to be recovered is 0s3
