So I heard that bacon (OnePlus One) got the camera working on custom ROMs by reverse engineering the camera blobs. I tried reading online, but I didn't have a proper link for this matter.
So the problem is the following, I'm owning the Sony Xperia Z3 Compact (codename "aries"), which stopped receiving Android updates (starting from Nougat), but in terms of custom ROMs based on CM or AOSP, the camera is not working. The device trees and the other files can be found on the freexperia github (https://github.com/sonyxperiadev?tab=repositories).
Reading the posts on XDA Developers I came across someone who claimed that by doing reverse engineering on the camera blobs, the camera might start working.
So my question is: are there any methods or tutorials regarding reverse engineering? Or any solutions for the problem that I asked earlier.
