WARNING: When using custom kernels on the S7, never turn off developer options or OEM unlock. If you do, you will lose all your data and have to flash a full stock firmware restore to use your device again!

OKAY SO

This is Kali NetHunter 3.15.2 for the Galaxy S7.

If you don't know what Kali NetHunter is, well, it's the entire Kali Linux operating system in a chroot on your phone, plus a bunch of awesome apps for executing exploits, fixing things, doing cool things. It goes on, I suppose.

I'm gonna be honest guys, I'm not a security person. When it comes to security, I'm more of a Paul Blart.

What I do know though, is that there is apt-get, and apt-get is life.

The answer to all your questions, generally the answer is YES, IT CAN DO THAT.

Most ROMs should be supported, as our installer uses a dynamic patching method on your current boot image!

The NetHunter installer zip will add a few files to your /system partition, and install all of the NetHunter apps to your /data partition.

The chroot is located in /data/local/nhsystem, so you don't have to worry about your system partition being full. It's full read/write capable.

Understand that the zip will replace your current kernel with a completely different one.

This is necessary because most stock or custom kernels don't provide the drivers needed to operate most of Kali NetHunter's features.

NetHunter also includes its own Busybox that gives you full large file support and some extra applets.

It will not overwrite your current one, and will happily install alongside it as busybox_nh.

DOWNLOAD

Current version: 3.15.2 (stable, 2016-11-04)

Please be careful to download the right version based on this table:

SM-G930F, SM-G930FD, SM-G930W8, SM-G930X: kernel-nethunter-herolte-*

SM-G930K, SM-G930L, SM-G930S: kernel-nethunter-heroltekor-*

S7 edge: You're in the wrong forum!

All others be sad.

For the apps, chroot, and everything other than just the kernel, you will also need to download:

nethunter-generic-arm64-*

See installation instructions before proceeding!

Downloads are available at: http://build.nethunter.com/nightly/

BEFORE INSTALLING

IMPORTANT: Kali NetHunter requires write access to your data partition!

This means that if your data partition is encrypted, you will need to use the [Format Data] button in TWRP to remove encryption.

This will delete all your data, including internal storage.

You should back everything up first before installing Kali NetHunter.

Samsung Smart Switch Mobile can be useful for this, and allows you to back up your apps to a location on an external SDcard.

Unfortunately it doesn't back up most app data.

The Kali chroot and apps are installed on your data partition (in /data/local/nhsystem for chroot). To initialize the chroot and install Kali Linux, you need to start the Kali NetHunter app.

The generic NetHunter installer will automatically install SuperSU. We try to keep it up to date, but it isn't always.

If you already have SuperSU or another root method installed, please simply delete the supersu.zip from the root of the zip file before installing it.

It's recommended that you restore or flash your ROM's original kernel before installing NetHunter.

It's become apparent that there may be issues with the stock ROM and this kernel, and that it might run best on a Note 7 port.

FULL INSTALLATION STEPS

Install Team Win Recovery Project to your recovery partition.

Recommended: If you have a custom kernel or SuperSU installed, restore your stock kernel. (called Boot in TWRP)

This isn't entirely necessary, but you may need to flash the NetHunter kernel again if SuperSU replaces it.

If your data partition doesn't mount in TWRP:

Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".

WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!

Once your data partition is formatted, go to [Reboot] -> [Recovery].

Download the kernel-nethunter zip specific to your device.

Without exiting TWRP, transfer the NetHunter kernel installer zip to your device over MTP* and flash it using [Install] in TWRP.

If you wiped your data partition in step 2:

Go to [Reboot] -> [System].

Set up your phone by following the Android setup wizard.

Once it's set up, reboot back into recovery.

For new installations: Download the nethunter-generic-arm64-kalifs zip.

For upgrades: Download the update-nethunter-generic-arm64 zip.

Without exiting TWRP, transfer the NetHunter generic arm64 installer zip to your device over MTP* and flash it using [Install] in TWRP.

Go to [Reboot] -> [System].

Wait 2-5 minutes for your device to finish setting itself up.

Open the NetHunter app to initialize the environment

You're done!

* MTP, known as Media Transfer Protocol, is the same way you transfer files from your PC to your device when booted into system.

UPDATING TO A NEWER BUILD OR UPDATING YOUR ROM

Follow the installation steps above. NetHunter can be installed over itself as many times as you'd like.

If you don't want to lose your chroot, flash the smaller update-nethunter-generic-arm64 zip instead.

THE KERNEL

RAN INTO AN ISSUE OR BUG?

In order for me to help you, you have to at minimum reply with:

The link to the exact zip you downloaded

Your device model

The name of the ROM you're flashing it on

The version and build date of the ROM you're flashing it on

A complete description of your problem

If your issue is with a specific app, it might be better to contact the developer of that app.

For Kali NetHunter bugs/issues, you can open a ticket at: https://github.com/offensive-security/kali-nethunter/issues

If your issue is during the installation (ex. flashing the NetHunter zip), then please collect a TWRP recovery.log for me.

If you found a problem and were able to fix it, and no one's mentioned it in the thread already, it would be kind to state the issue and your fix for others to make use of as well.

You can join me and the other NetHunter developers on IRC at the #nethunter room on freenode to more handily diagnose problems together.

I apologize, but I can't do house calls at this time.

KNOWN ISSUES

USB Keyboard - The keyboard is unusable when using Google Keyboard as your input method. Switch to Hacker's Keyboard.

Reboot after 60 seconds - Sometimes when you boot your device it could reboot after 60 seconds because of a Samsung secure service not responding. Unresolved, but rare, and only happens within 60 seconds of a boot.
