I am running stock 4.4.2 with twrp 2.8.3.1 and it has knock on feature. Once i flash your kernel it no longer works. I did read the op and used the ota app and flashed it via your app, thinking it would detect the correct verison. Was i wrong?
It downloaded the version itself i did not see an option to get the knock or no knock version in the app.
then report this to app DEV. and download the no knock code ver from my storage for your model.
install via recovery and be happy.
