Please help me @davidanderson , or anyone else who can help me with my problem.
I found your advice on this page: Lost my APFS partition after using EaseUS partition manager on Bootcamp
I did the same thing – used EaseUS to reformat a windows drive to be larger, and made my APFS unbootable. I followed the instructions:
From Windows, you can open a Command Prompt window as an Administrator. Next, you could enter the commands given below to change disk0s2 to an APFS type.
select disk 0
select partition 2
set id=7C3457EF-0000-11AA-AA11-00306543ECAC override
Which recovered my APFS drive perfectly. I also had a partition (number 3 on disk 0) and it was an OS X Journaled Extended drive (Which I think is HFS+). Frantically, I ran the same script above changing that drive to APFS, which is still unusable.
I’m so clueless and trying to scour the internet to figure out how to change the drive back to HFS+ so it can be accessed again. Thanks in advance!
