Kernel Flashing Instructions

For this kernel to work properly, there are some steps that need to be done.

Please also note that the instructions provided are made for a clean installation.

As for now, dirty installations (==with data preservation) are not tested nor researched.

Also keep in mind that after executing all of the documented steps, your device will have disabled DM-Verity and Force Encrypt, which can be seen as (and actually is) a security risk.

0. Backup

Before doing anything to your device, make a backup.

It is highly recommended to do a NANDroid backup via TWRP.

Backup should be made with removed lockscreen passwords/fingerprints/PINs. Otherwise there might be some issues during the flashing process.

1. Download assets

Listed below files are required:

  • compiled kernel, obviously;
  • ROM;
  • Magisk or KernelSU;
  • TWRP, the special build by faoliveira78 (supports operations with encrypted and dynamic partitions);
  • DM-Verity and Force Encrypt disabler;
  • Kali NetHunter + Kali NetHunter Terminal apps;
  • Kali NetHunter Chroot (you can do this later, but it would be easier to download this beforehand);
  • nhpatch.sh script from this repo (fixes NetHunter permissions for Android 12+) with recent NetHunter app versions, nhpatch.sh usage is no longer required.

Currently, all of the mentioned assets can be collected via the assets subcommand (use full option).

2. Flashing

Note: Once again, this instruction is for clean installation only, meaning that you will lose all your data.

The installation process is done in the following order:

2.0 Some checks

Before doing anything, please ensure that you have:

  • an unlocked bootloader;
  • an installed TWRP recovery;
  • a working NANDroid backup of your device.

2.1 In TWRP

  • wipe your phone via Wipe -> Advanced Wipe menu, check all the shown boxes;
  • wipe your device again via Wipe -> Format Data menu (this will remove any encryption that is present on your device);
  • reboot into TWRP via Reboot -> Recovery;
  • if using a Retrofit Dynamic Partitions ROM such as ParanoidAndoid -> untoggle Unmount System before installing a ZIP in the Settings;
  • flash the ROM;
  • flash the kernel;
  • if using Magisk --> flash Magisk root manager (you must change the .apk extension into .zip for this);
  • flash DM-Verity and Force Encrypt disabler zip;
  • reboot into system via Reboot -> System .

2.2 In OS

For Magisk users

  • install Magisk apk, open it and do what the pop-up says (finish root installation, which will automatically reboot your device; if you don't see the pop-up, close the Magisk app and open it again);
  • once booted back into OS, open Magisk app again and proceed with finishing the installation (when prompted with "Additional Setup", select the default Patch vbmeta in boot image in Options and Direct install in Method submenus);
  • install NetHunter + NetHunter Terminal apps;
  • open NetHunter app (if seeing a Busybox-related error, press "OK" and re-open the app);
  • navigate to the Kali Chroot Manager submenu and install the chroot (if you downloaded it beforehand, use the "restore" option);
  • make sure that your NetHunter and NetHunter Terminal apps are properly configured to see the installed chroot directory (by default it may be /data/local/nhsystem/kalifs; if you see it anywhere, change it to /data/local/nhsystem/kali-arm64);
  • in NetHunter Terminal app open Kali shell (if it opens properly, then congratulations, you have a working Kali NetHunter on your device).

For KernelSU users

  • install KernelSU Manager app, open it and verify that the Superuser tab works properly (should show the Shell item);
  • install NetHunter and NetHunter Terminal apps, but do not open them yet;
  • open KernelSU Manager app, grant SU permissions to both NetHunter and NetHunter Terminal apps via Superuser tab;
  • open the NetHunter app (if seeing a Busybox-related error, press "OK" and re-open the app);
  • navigate to the Kali Chroot Manager submenu and install the chroot (if you downloaded it beforehand, use the "restore" option);
  • make sure that your NetHunter and NetHunter Terminal apps are properly configured to see the installed chroot directory (by default it may be /data/local/nhsystem/kalifs; if you see it anywhere, change it to /data/local/nhsystem/kali-arm64);
  • in NetHunter Terminal app open Kali shell (if it opens properly, then congratulations, you have a working Kali NetHunter on your device).

For x_kernel-based kernel + ParanoidAndroid users

This is a small side-note for using x_kernel-based build with ParanoidAndroid ROM. When booting into OS, you will see a message that There is an internal problem with this device. Please call manufacturer.. This warning is essentially similar to the unlocked bootloader message and is completely harmless. Press "OK" and proceed.
