You are going to need the engineered bootloader first, then you might be able to down grade to the na4, once you do that, hopefully it will let you go back to mj4... I'll grab a couple more links for you...

I can't seem to find them from my phone, if you do a search in the threads, look for na4 tar and mj4 tar, if you can successfully get back to na4, you will need to flash mj4 twice, after the second flash, go straight into stock recovery and do a wipe and then it will start back up... Like I said, best of luck man. And read the forums, you don't want to risk bricking.
