iPhone folder permissions iOS 8.1 HELP!!

[wattabing]

so now my camera won't save pictures when I take them. I need to find that folder and change permissions but also thumbnails are blank but when I lclick the empty thumbnail the picture shows up. That's for photo stream. Below is a copy of a post I made earlier in the wrong spot. My camera was working before but now it's not. Not sure if texts are getting pictures now either. Will have to check. But really want to know what folders I need to change permissions on to get all this fixed. There are a few spots I know that's for sure. Cause I did fix the camera at one point and also the texts but never got the thumbnails of old pictures working. And screen shots not working but that's the same as the camera folder permissions I believe. Anyways here is old post I made

So you seem to know what you are talking about, i just restored my iphone 6 with a iTunes backup of a jailbroken ios 8.1 from iphone 5s and restored it to iPhone 6+, but now my thumbnails in the photos app are not showing up, well they are just blank image holders, and when i click on them the pictures are there.. I also had this problem with the text messages and also camera pictures not saving, but i resolved those two issues by changing permissions on a few different folders, does anybody have any idea what folders the photos are stored in the ios firmware.. I have the icloud photo library (beta) on and upload to my photostream also on and i cloud photo sharing... But none of photos show the thumbnails EXCEPT for photos taken with the camera... THANKS oh fyi, i was ablke to see photos in my text messages again after following directions from this thread, it was a permissions problem... So i'm assuming this is too, just dont know where the folders are... I did change permissions on a few folders so far and it didnt work, i think they were called like photostreamdata, photodata, etc...

You might want to try the Jailbreaks and iOS Hacks subforum. Since it seems your trouble is related to jail breaking and/or tweaks made while jailbroken, you may get better help from the JB community.

My advice would be to save off the photos and then clean-restore the phone with a fresh 8.1 download via iTunes, then set up as new not restoring any prior backups. Probably not what you want to do though...

If you don't have iCloud Photo Library enabled, it is safe to delete the entire PhotoData folder and reboot. This will repopulate the photo library based on what is in the DCIM folder, and generate new thumbnails. Back up the PhotoData folder to your computer in case it doesn't go well. You can modify the PhotoData folder without jailbreaking by using iFunBox on a computer.

DO NOT do this if you are using iCloud Photo Library, or it will re-download all of your cloud photos.

If you still can't save photos, you may have to erase the phone and set it up as a new one. You can import photos using an app called FileExplorer, and iBackupBot can selectively restore app data.
