The wifi does not turn on, why?
How did you install the rom? Here is what I did, and will repeat some of what is in the op.
1) If coming from another rom, do a factory reset 3 times first.
2) Wipe cache dalvik cache, system data next 3 times
3) Format data 3 times
4) Odin full stock tar OK1
5) run through the set up
6) install TWRP again, but do not root.
7) repeat steps 1 and 2 . Even if you did not install anything during set up.. I find that if you do not do this, you will have issues..
8)Flash rom and nothing else, keep stock kernel
9) When done do not reboot, pull battery and hold power button in for 20 secs
10) Put battery in and reboot.
11) Once it comes to the welcome screen, make sure you have at least the cell signal triangle showing. If no LTE Turn off WIFI, if LTE shows up for a sec, then goes away turn WIFI back on. If LTE shows again, and stays let it sit for 3 min before you complete your set up. During set up, do not connect to a WIFI network just yet.
12) Finish set up. If you get a "Google Play Services Stopped" ignore it..
13)Once you are all set up, go to play store first to see if it loads, it might take a couple of minutes.
14) Once play stores loads, close it and go to Setting> System Update and do a PRL update.. If it says no PRL update no worries your up to date. Do a Profile update, and after that you should be done.. You DONT have to do a Reactivation as sprint already knows you have the phone.
I had issues when I first tired this rom, and left it for a few weeks.. Went back made sure I did everything right, and now it works great, and I do not plain of updating again to MM or any Note 7 Roms.
