I feel like an idiot, I was having the so called WiFi issue, but I realized I was not S-OFF, so guys experiencing the WiFi issue, please pay attention to the pre-requisites. Also, if you try to flash this from CWM it will tell you if you want to overwrite the Recovery, I think the right answer would be yes, but it makes you think that telling no will render you custom recovery-less. So again, as Paul you suggested, better to stay on TWRP.
I am now experiencing the issue where I try to switch to GE(having disabled the Fast Boot option already) and it would boot again to Sense. Tried this 3 times, will be testing a couple of other things before even calling this an "issue". Will post my results later on.
BTW, my model is Developer Edition.
Now my bootloader reads like this(after proper Revone S-Off):
*** UNLOCKED ***
M7_UL PVT SHIP S-OFF RH
Radio: 4a.17.3250.14(I upgraded to this as troubleshooting for the so called "WiFi issue" but didn't fix it, as stated above proper S-OFFing did the trick)
