I was running CM 11 M5 when I realized that my camera app wasn't working, so I decided to go back to CM 11 M4. I have CWM and didn't wipe anything, just reflashed over M5. When I rebooted everything was crashing and I didn't do anything. So I booted back into CWM tried wiping and formating everything. I was wiping data fine, but it wasn't formating. I wanted to go into my backups but they are all gone.
I've heard of somehow fixing this through ADB but I don't know how to use it.
I am so desperate guys, please help!!!
