[Q] wifi not turning on topic

hi, i have a little problem and let me explain it.

i have a mexican moto maxx and i decide to update to lollipop and i followed the instruction, downloaded the br firmware and then flash the files that are listed, then i update to lollipop, but i didnt like very much lollipop, i think it need a little more tweaks for work better and i decide to downgrade to kit kat again, and i follow some instruction like for example flash all files from br and then i thought i could just flash the mx files and leave it like factory.

but it didnt work like i thought, i was not able to flash system and other img like this, i just flashed radio and now my wifi is not working, i tried to reflash the radio from the mx file but im still not making it work, the wifi just dont turn on.

my phone still have the bootloader locked, any ideas?:(
