I was installing cyanogenmod but something soft-briked it so I went back and did the unrooting process but this time installed 4.4.2 instead of the older rom. After trying to root I learned that the stock rom I was on patched rooting away. Now I'm stuck and even trying to downgrade I get the following error in odin. All my searching I haven't found anything on how to fix this. Can someone help, all the guides on the forum do not work.
