An unstable version of Android 5.1.1 caused a bootloop on my phone. I fixed things, but after the incident the
0 directory located inside
/storage/emulated/0 dived DEEPLY DOWN. Now I can't delete anything inside.
I guess it's because the path is too long. I successfully used 7zip once I had that problem in Windows, I wonder if something like robocopy or subst method is possible on Android. Here's a screenshot of me gaining root access and then trying to wipe things out which was not successfull.
