Pardon me ( and I do mean it)if I misread/misunderstood your meaning, but I interpreted "I am in a bootloop, so your fix seems like the perfect solution." as sarcasm.
I would suggest that you pick one method of unrooting/rerooting/updating and stick with it from start to finish, following the instructions to a tee. When you mix various procedures and fixes, sometimes part of one will break another. I highly recommend R3L3AS3DROOT as it has worked well for a lot of people.
