So I was using the Minin3 Maximus 5.6 rom for quite a while now. But I was wanting to try out some aosp roms so I made a backup and installed Carbon rom nightly build. Used it for a few days but I have actually got really adjusted to touchwiz. Thus I wiped everything, installed the backup, now my internal storage is just not responding. Everything works just fine. However I can not download any images, save videos from youtube, basically anything that will save to internal storage. I have already tried going to twrp and rewiping everything, tried fixing permissions, everything I can think of. This happened once before and I had to completely wiped the whole phone and external sd card to get it to work. Really trying not to do that again. Any help is much appreciated.
