Last week I got a Nexus 5 device for myself.Since then I am using it with omni rom home builds , I did compiled omni with usb modules enabled kernel. I have tested atheros and rtl8187 drivers both works fine with airmon and droiddump. Though I haven’t tested them on a packet injection scenario I hope they will work. Later this week or next I will do a full test and probably post the video. IF anyone want to experiment download the flashable zip down below.
