Default New OTA odin issue.

Hi. I update new OTA and was rooted using Kingo and have safestrap. Then I installed a zip file, then wanted to remove it, so I just decided to ODIN back to MJ7. Now the phone keeps crashing process android.porcess.acore has stopped. Not sure how to fix it. I have lost root and safestrap is still installed. Any assistance would be appreciated. Thanks.
