1) InitialCFRootFlasher.zip from Chainfiire you can get it here
2) A stock kernel zImage: you can download any stock kernel and extract the zImage from it. I have attached a copy of a rooted XXKKA stock kernel I have backed up from my device
Simply flash the stock kernel image using Chainfiire tools and the triangle is gone.
You can then use the same tool to flash any other kernel you want and the triangle will not show again.
Kudos to Chainfiire for all his work and to ookba for saving my .... last night
N.B.: This will not reset the counter only remove the triangle
