Update from 10.1 to 10.2 has screwed up boot

[onesojourner]

Hello all. I recently updated and everything went fine my phone booted after the update and I ran 10.2/4.3 for about a week. I then rebooted my phone but it hangs / freezes on the screen with the Samsung Galaxy Siii logo and cid the cyanogenmod guy. I rebooted several times with the same result. I had been wanting to try out the dirty unicorns rom so I installed that, it boots fine, runs fine but as soon as I try to reboot I get stuck on the cid screen, I have to format my memory on the phone and reinstall a rom. For some reason twrp is not able to wipe all the memory that is why I had to format it. If I reboot I have to go through the process again. Has any one seen this before?
