I am using the android-kali image from the kali website.
so my kali is boot 2. (I hold the silver button down after vibrating to get into kali.)
I should mention I swapped the 3.18.41kali+ kernel for the one located in this blog post.
https://www.mygnu.de/2019/03/modular-linux-...h-cutpaste-fix/so my kernel is 3.18.41+ which differs to the 3.18.41kali+ kernel.
I am using the modules from the same blog post as well.
I used the flashing tool to flash the kernel, as flashing manually using the dd command did not seem to work at all under kali. (After bootloader Linux crashes and then it just restarts and boots the default android instead.)
I also used the 5GB to android 50GB to Linux scatter file from here:
https://github.com/gemian/gemini-keyboard-apps/wiki/FlashingI might be wrong in what I think you mean by firmware but I have the firmware-atheros, firmware-libertas, firmware-misc-nonfree, firmware-ralink and firmware-realtek packages installed.
Sorry if that is unhelpful.
my version of kali is of course 2019.1 as specified on the official kali website.
