Note 4 5.0.1 Not factory resetting after CF- Auto Root

Hello Everyone,

This is the first time I have ever posted anything on any forum online. I have used XDA to get help while fiddling with my devices before so I would just like to thank all of those who share things on forums.

I have a Note 4 SM-N910c running Lollipop 5.0.1. A few days ago I used CF Auto Root Method to root my device. Needless to say, it worked perfectly. However, today I wanted to factory data reset my device just to remove all the files that I have in my phone. I should mention that I am not trying to 'unroot' my phone. Just reset it.

So I went to the settings and factory data reset my phone but this is where the problem began. After clicking 'Erase All' my phone turned off but then a small android animated figure appeared with the words 'Installing System Update' visible beneath it and then suddenly a red faced down android appeared with the words 'error' beneath it. Then my phone went into the stock recovery where I rebooted my system and my phone turned back on without resetting it.

So my question is that, what in the world just happened and how can I reset my phone? I should also mention that I have no custom recovery installed and I have no custom rom intalled. Can anyone please guide me thru this, I would very much appreciate it.

Thank you for your help.

Need help "resetting" phone to its original state

Firstly, I apologize if this is the wrong forum to post this on, but I am becoming somewhat desperate for help and found none of it on various other forums I tried.

I have a Huawei Honor Holly (Hol-U19) which I recently rooted. I then attempted to install a custom ROM and ClockworkMod, but somehow it all ended in me not being able (as far as I know) to access recovery mode - not by pressing the specific buttons during startup or via software like Flashify. I'm not sure that ClockworkMod is still installed. The phone doesn't show up in Windows Explorer (whether USB debugging is on or not or the SD card is inserted or not) or ADB (using Minimal ADB and Fastboot).

The gist of it is that I don't know how to install the stock ROM to "reset" it back to its original "form", and I really need some help on this. If you need any other specific information, I'll try my best to give it to you.

Max CPU speed keeps resetting to lower value?

I dont know what I did but now no matter what kernel i run or kernel manager.. despite the fact that the kernel supports speeds of say 2649... eveyr time i change it to 2649, it changes right back to 2265 or even 1958.

it happens in FKU, Kernel Adiutor, Trickster etc..

i have tried flashing stock back, then reflashing FK, or Hell cores, or Pure Nexus o Despair.. all same thing.. I can not set a max CPU speed beyond 2265 and have it stick.
what am I doing wrong? I have had this before in the past and it just went away on its own.
