Marshmallow broke my knock code on LG V10

[Akirakun1]

After an accidental Marshmallow update to my LG V10 the original lock code didn't work well & fingerprint sensor did not work at all. It took me about 30 min to get into my phone using the lollipop 3-4 knock code. I immediately set up a new fingerprint save and re-entered the same knock code then created a security pin number however I am still unable to unlock my phone using the fingerprint sensor alone and I need to enter the lock code about 8~10 times.

I've discovered that the Marshamallow lock code has increased the security to the knock code to a minimum of 6 knocks. Please offer a quick fix. I need to disable the knock code but I am unable to reset it through the settings menu as it always says it didn't recognize the knock code and to retry.,

Akirakun1, having access to your phone is a must. Help is here to ensure this happens for you. I want you to love your new software as it is meant to enhance the device. My apologies that you are running into issues. Because of the knock code being unknown, the best next plan of action is to do a complete master reset so that you can then gain access to your device. I do hope there was a back up of your device’s content. Please click here for the steps for master reset. http://spr.ly/6584BxsAk

The knock code minimum requirements have changed. I did not forget the knock code. Please don't assume things and ask questions if things are unclear. I feel as I was disrespected by implying it was user error. I'm relieved that you didn't imply that I forgot my fingerprints. This is issue was the result of a Google marshmallow update security increase without being shown a EULA and the ability to get rid of the nagging update. LG was contacted through their phone support directly but they seemed to point fingers to Verizon and Google. 

I've resolved my issue by typing my correct 4 knock code more than 6 times entering my pin and marshmallow requested a new knock code and fingerprint calibration. I hope this proves helpful to moderators and users in this community.
