I haven't used this phone in months and I have a new phone so I'll be giving this guide off of pure memory. Don't worry though, I remember most of the process 
.
********WARNING!**************************************
This will UNROOT your phone and REMOVE USER DATA so use this if you're testing things out and want to restore to stock.
******************************************************
Step one:
Download this file from the link.
Huawei M920 Firmware
Step two:
Place the "update" folder in the root of your SD Card. There should be a file called "tfupdate.img" inside the folder.
Step Three:
Turn off phone.
Step Four:
Hold the Vol Down button while pressing the power button.
You should see a screen saying tfimage update or something along those lines and you should see it saying something about unpacking and installing. If I'm mistaken and you don't see a screen like that than do the same thing but instead of the Vol Down button press the Vol Up button. (Some confirm for me please)
Just leave the phone alone and once it boots your phone should be completely factory restored to stock.
Hope this can help
