Recover Notes data after factory reset? I have an OnePlus One phone that was then on an old version of Cyanogenmod I factory reset by accident a few years ago. I used the OS notes app back then (it wasn't backed up) and I would like to recover them. 

When looking at the files on the phone from USB on my Macbook pro a while back, I noticed there was a folder called O which has seemingly a whole new OS file tree. 

I used the phone after the factory reset and after a while when I ran out of disk space quickly (it has 64gb) and on using the space calculator in settings I found out 22gb was being used Misc! I am assuming this is the old OS and so wonder if the notes can be recovered. Looking through the files on my Macbook file explorer on the phone I have not been able to find the notes data files. I Googled a while back and I think the notes are stored in XML. 

Is it possible to recover these?
