I am Luca from France. Today, it's my birthday, I am already 16 and I got a Nexus 5 32GB.
I tried installing Hammerheadmon kernel (Download at: https://build.nethunter.com/nightly/...03-13-0514.zip ). I noticed it was based on ElementalX.
So I downloaded latest ElementalX nougat build for Nexus 5 ( https://www.androidfilehost.com/?fid=962187416754455497 ), and tried replacing "elex.zImage" by "zImage-dtb" of hammerheadmon kernel's zip.
After flashing the original hammerheadmon nethunter kernel, I flashed the modified ElementalX zip with hammerheadmon's zImage. And I successfully got my internal wifi card in monitor mode while my CPU was overclocked and undervolted.
I am running Unofficial LineageOS 14.1.
Download the 2 zips to flash below.
Note: You have to flash original Nethunter hammerheadmon kernel first in order to install all drivers. Obviously, you can't flash ElementalX edited zip first, because Nethunter kernel will replace you actual zImage-dtb in you boot partition that allows overclock by its own that doesn't.
PS: Congrats to @flar2 for developping ElementalX. I think it is amazing that in TWRP you can patch zImage for higher/lower voltages. I still haven't figured out how he managed to do that.
