[Guide] Debian on Android (rooted)

Hi, this is a guide to install a Linux image on your rooted Android phone with the debootstrap + chroot method.
In this guide, we'll install a Debian image, but the steps are practically the same, with a few tweaks.
If you need help to install a Linux image, feel free to ask on this thread.

________________
I. On your PC
So first, you have to create the .img file that will contain the OS.
In a GNU/Linux environment (PC) and with the root permissions, type these commands:
Code:
# mkdir debian
# dd if=/dev/zero of=wheezy-armhf.img bs=1M count=0 seek=2048
[COLOR="Red"](NOTE: "of=" will be the name of our .img file and "seek=" the size of the file (MB). Here, we create a file named "wheezy-armhf.img" of 2 GB)[/COLOR]
# mkfs.ext4 -F wheezy-armhf.img
# mount -o loop wheezy-armhf.img /debian
Then we have to fill up the filesystem.
Code:
# debootstrap --foreign --arch=armhf wheezy debian/
# umount debian
Finally, move it to your SD Card. In my case, I moved it on /data/local/
II. On your phone
On your phone, in a terminal emulator and with the root permissions, type the following commands:
Code:
# mount -o rw,remount rootfs /
# export LINUXROOT=/linux
(NOTE: here we'll install Debian on the root of the internal memory, in "/", but we can also install Debian on the SD Card or in /data/loca/linux by changing the path after "LINUXROOT=")
# mkdir $LINUXROOT
# busybox mknod /dev/block/loop100 b 7 100
# losetup /dev/block/loop100 /sdcard/wheezy-armhf.img
# mount -t ext4 /dev/block/loop100 $LINUXROOT
# chroot $LINUXROOT /bin/sh
# export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# /debootstrap/debootstrap --second-stage
The debootstrap's second part should start. Grab a cup of coffee while it's working!
When it's finish, leave the chroot by typing
Code:
# exit
# su
Let's mount the filesystem. We're close!
Code:
# mount -t proc none /proc
# mount -t sysfs none /sys
# mount -o bind /dev /dev
# mount -t devpts none /dev/pts
Now, we have to set the environment variable. Ensure that you have set the correct path of LINUXROOT in case you've chosen another path than /linux.
Code:
# export LINUXROOT=/linux
# export TMPDIR=/tmp
# export USER=root
# export HOME=/root
# export SHELL=/bin/bash
# export TERM=linux
# export LC_ALL=C
# export LANGUAGE=C
# export LANG=C
And finally, chroot.
Code:
# chroot $LINUXROOT /bin/bash
su
Welcome on Debian!
III. DNS and Mirrors
Set a DNS. We'll set the free Google DNS but you can set yours if you want.
Code:
echo -e "domain local\nsearch local\n" >> /etc/resolv.conf
echo -e "# DNS Google\nnameserver 8.8.8.8\nnameserver 8.8.4.4\n" >> /etc/resolv.conf
You can add mirrors to your sources.list if you want. I'm french so I added french mirrors:
Code:
# echo -e "## Debian Wheezy sources.list\n\n" > /etc/apt/sources.list
# echo -e "## Debian.org FR mirror\ndeb http://ftp.fr.debian.org/debian/ wheezy main contrib non-free\ndeb-src http://ftp.fr.debian.org/debian/ wheezy main contrib non-free\n\n" >> /etc/apt/sources.list
# echo -e "## Debian security updates\ndeb http://security.debian.org/ wheezy/updates main contrib non-free\ndeb-src http://security.debian.org/ wheezy/updates main contrib non-free\n >> /etc/apt/sources.list
IV. VNC
To access your Debian in a graphical environment from your PC or your phone, you have to set up a VNC Server and install a Desktop Environment. Let's install VNC and LXDE.
We'll follow the steps described on the LXDE wiki:
Code:
su
# apt-get update
# apt-get install lxde
# apt-get install tightvncserver
Set up the VNC server by typing the following command, which will ask you to set two passwords (let the second password if you want):
Code:
# vncserver
Kill the session:
Code:
# vncserver -kill :1
Go to /root/.vnc/ and edit the xstartup file: comment out #/etc/X11/xsession and add these two lines:
icewm
lxsession
Click to expand...
Click to collapse
To start a VNC session, type "vncserver -geometry x". For the Nexus 4, we would type "vncserver -geometry 1184x768"
To access your Desktop Environment from your phone, download android-vnc-viewer and launch it.
In the password field, type your password. In the address field, type "127.0.0.1", in port type "5901" and select 24-bit color (4bpp).
V. Script
I've made three scripts to mount, launch and unmount Debian. Whenever you reboot your phone, you'll have to mount Debian, set the environment variables and chroot.

Sorry for my bad english, I hope this will help

EDIT: Feel free to correct me!

Hi, I have 2021 updates, if someone interested. Tested with rooted LineageOS 17 (selinux permissive - not sure if required, my ROM is permissive, didn't set it explicitly):
for 32-bit ARM, ext4 created by 64-bit Linux didn't work, obviously there is some 64-bit feature that was not supported at least with my kernel (3.14). I've in the end created the FS on the Android, but using "-O '^64bit'" could be sufficient in the Linux. UPDATE: I've in the end used F2FS instead of EXT4.
above mknod+losetup+mount didn't work for me (neither 'mount -o loop -t ext4 <img>'), I've used 'mount -t ext4 $(losetup -sf /sdcard/stable-armhf.img) $LINUXROOT' in the end (obviously the device name needs to be saved somewhere if one wants to cleanly umount)
there was issue with network access denied even if you are root, see here. I've fixed it by creating the group 'inet/3003' in the chroot and issuing 'newgrp inet' inside it (more details in the link).
Anyways, thanks a lot for the above instructions, it helped me much!

[REF][ServiceMode] How to make your Samsung perform dog tricks

Every time Samsung releases a new series of phones, they try to make
it just a little harder for us to find and enter the Service Mode (SM)
menus. Understandably the Service Mode menus allow you to access
functions on your phone directly related to its operation, from
selecting particular service providers, unlocking your SIM card,
changing default networks, bands and destroying your internal
non-volatile (NV) memory, that contain all your IMEI, RF, EFS
parameters, and to make a complete factory wipe and reset.
So this is not to play around with, randomly!
You have been warned.
On the other hand, it also provides extremely useful detailed
information about your mobile network, including all radio related
systems like GPS, WiFi, BlueTooth and NFC. Most of this information
is not available through the usual AOS Java API, and probably will
never be, as vendors consider this area as off-limits to users and
amateur developers.
Note:
All this info was obtained on a European
Samsung Galaxy S4-mini (GT-I9195 LTE)
But reported to work also on:
Samsung Galaxy S5 on US Cellular (SM-G900R4)
Code:
[SIZE=2]Baseband: I9195XXUBML4 [/SIZE]
[SIZE=2]Kernel: 3.4.0-2340422 [/SIZE]
[SIZE=2] [email protected] #1 [/SIZE]
[SIZE=2]Build: JDQ39.I9195XXUBML4 [/SIZE]
[SIZE=2]SE: SEPF_GT-I9195_4.2.2_0022[/SIZE]
Getting into Service Mode (SM)
On this particular model, you have to do this:
Go to dial pad and enter: *#0011#
This will initially take you to Service Mode and showing you
various signal status items, by default. But it's a locked
entry. So to unlock and go to the Main Menu do this:==> [MENU] + [Back]
==> [MENU] + [Key Input] + "Q0"
==> <wait ~5-10 seconds>​Now you can hit the thank you button below!
I have not seen this solution anywhere else, and
it required some reversing...
Understading the ServiceMode Menu
<WIP>
This will take some time to investigate, so anyone
who already knows, please post in this thread.
The ServiceMode Menu Structure (brief)
Go to Post#2 for formatted menu structure and items.
Code:
[SIZE=2]MAIN MENU[/SIZE]
[SIZE=2][1] UMTS [/SIZE]
[SIZE=2][2] CDMA [/SIZE]
[SIZE=2][3] LTE [/SIZE]
[SIZE=2][4] SIM- Not Used. --> <E>[/SIZE]
[SIZE=2][5] DOCOMO DEBUG SCREEN [/SIZE]
[SIZE=2][6] run EFS SYNC() [/SIZE]
[SIZE=2][7] DEBUG SCREEN [/SIZE]
Some Important Codes
9900 SysDump
This is an important hidden code is that for making a wide range
of system dumps and changing many unknown logging functions.
This will give you a list of the following functions:
Code:
[SIZE=2]Menu Item Setting Description[/SIZE]
[SIZE=2]---------------------------------------------------------------------[/SIZE]
[SIZE=2]Run dumpstate/logcat/modem log - logcat -v threadtime -b radio -d -f /data/log/radio_*.log[/SIZE]
[SIZE=2]Delete dumpstate/logcat [/SIZE]
[SIZE=2]Run dumpstate/logcat [/SIZE]
[SIZE=2]Copy Kernel Log to SD card [/SIZE]
[SIZE=2]Run CP based log [/SIZE]
[SIZE=2]Run Forced CP crash dump [/SIZE]
[SIZE=2]Copy to sdcard (include CP Ramdump) [/SIZE]
[SIZE=2]Debug Level Disabled/LOW - Change debug level [LOW/MID/HIGH][/SIZE]
[SIZE=2]CP Debugging Popup UI: Disabled [/SIZE]
[SIZE=2]Silent Log: Off dev.silentlog.on=(On,Off)[/SIZE]
[SIZE=2]Translation Assistant: Off persist.translation.assistant=(0,1)[/SIZE]
[SIZE=2]Low battery dump: Off [/SIZE]
[SIZE=2]Wakelock Monitoring: OFF [/SIZE]
[SIZE=2]TCP DUMP START ro.product_ship=(true,false) lucky_ril*.log[/SIZE]
[SIZE=2]Enable SecLog (currently disabled) persist.log.seclevel=(0,1)[/SIZE]
[SIZE=2]MTT Logging Setting: OFF persist.brcm.log=(sdcard,none) [Broadcom][/SIZE]
[SIZE=2]ACT data copy [/SIZE]
[SIZE=2]Exit [/SIZE]
9090 DIAG CONFIG
This is also important for changing the internal MUX used for
diagnostic debug output, to/from USB and UART.
Code:
[SIZE=2]DIAG CONFIG[/SIZE]
[SIZE=2][1] USB ( )[/SIZE]
[SIZE=2][2] UART (*)[/SIZE]
[SIZE=2][3] DBG MSG ON (*)[/SIZE]
[SIZE=2][4] DBG MSG OFF ( )[/SIZE]
Basically if you wanna use UART output, you will probably need
to build the MyWay box or use the correct resistance between
the USB ID and GND pins. (See my AnyWay thread.)
0808 USB Settings
This is by far the most important code to know, because it is used to determine,
what drivers are enumerated when connecting your phone to PC via USB cable.
Technically it is a multiplexer (MUX) switch which determine whether the USB
port is directly connected to the CP (Cellular/baseband Processor/modem),
or the AP (Application Processor). This also selects what device features will be
enabled once connected. Such as ADB, RNDIS, and DM (Diagnostic Mode) etc.
To change the mux settings on a Samsung S4/mini, use your dialpad
to get to the "USBSettings" menu, like this:
For AOS <= 4.2.2, without SELinux, use *#7284# or *#3424#.
For AOS >= 4.2.2, with SELinux, use *#0808#.
Code:
[SIZE=2]USB
( ) CP
( ) AP
USB Settings
( ) MTP
( ) MTP + ADB
( ) PTP
(o) PTP + ADB
( ) RNDIS + DM + MODEM
( ) RMNET + DM + MODEM
( ) DM + MODEM + ADB
[OK] [Reboot]
[/SIZE]
A few other service/secret codes
Similarly to my GT-I9300 "Secret Codes" thread, we find many of the
same codes present also in this phone. Do check that thread out, for
understanding how to find more codes relevant for your phone and AOS
version. Also note that most custom ROMs does not support all these,
as they are usually left out or forgotten about, since they are
vendor/modem specific.
Here I show only the most interesting & useful ones, and I have also
used the excellent website PhoneSpell to try to find sensible word
combinations for some of these numbers.
Now, many of these seem not to work at all, but they are present in
the ServiceMode application(s) code and rely on various other
properties being set before being available/activated. Another
type of block is is determined by the content of the EFS files:
/efs/FactoryApp/keystr
/efs/carrier/HiddenMenu
These can be set on a rooted phone by:
Code:
echo -n "OFF" > /efs/FactoryApp/keystr
echo -n "ON" >/efs/carrier/HiddenMenu
echo -n "ON" >/efs/FactoryApp/factorymode
(Somebody need to confirm the KeyString block boolean!)
Here is list of some particularly interesting properties that often
seem involved in blocking/enabling particular ServiceMenu
items/features.
Code:
[SIZE=2]property value/note[/SIZE]
[SIZE=2]---------------------------------------------------------------------[/SIZE]
[SIZE=2]ril.tcpdumping=On [On,Off][/SIZE]

[SIZE=2]* SOS = Sell Out SMS[/SIZE]
[SIZE=2]<> = some kind of keypad pattern[/SIZE]
[SIZE=2]---------------------------------------------------------------------[/SIZE]
In addition to these numerical codes, there are also few alphanumeric ones.
These can be used from the command-line with the "am" command, like this:
Code:
[SIZE=2]am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://CP_RAMDUMP[/SIZE]
This might also work when already in ServiceMode, by entering the string
after selecting "Key Input" or "Select", from menu. (I have not checked.)
Code:
[SIZE=2]LTE_ANT_PATH_NORMAL[/SIZE]
[SIZE=2]CP_RAMDUMP[/SIZE]
[SIZE=2]DUMP_SVCIPC[/SIZE]
[SIZE=2]DEBUG_SCR[/SIZE]
[SIZE=2]EI_DEBUG_SCR[/SIZE]
[SIZE=2]DATA_ADV[/SIZE]
[SIZE=2]NAMBASIC[/SIZE]
[SIZE=2]TESTMODE[/SIZE]
[SIZE=2]NAMSIMPLE[/SIZE]
[SIZE=2]TEST_CALL[/SIZE]
The Samsung Diagnostics Menu
One special secret code is that of the Samsung Dignostic
Test Menu. This particular menu exsists on pretty much all
Android based Samsung phones. (AFAIK) The code is simply:
*#0*#
It provides for testing things like the Screen, Sound, Vibrator,
all the sensors and more. One one the cooler features for phones
that include an IR transmitter, is that you can use it on most
modern Samsung TV's as a remote control. Thus even easier to use
than any of Samsung's own Remote Control Apps, which are often
bloated and containing spyware.
The available test items you will find on this particular model are:
Code:
[SIZE=2][Red] - screen pixel test[/SIZE]
[SIZE=2][Green] - screen pixel test[/SIZE]
[SIZE=2][Blue] - screen pixel test[/SIZE]
[SIZE=2][Receiver] - (Ear) Receiver test[/SIZE]
[SIZE=2][Vibration] -[/SIZE]
[SIZE=2][Dimming] -[/SIZE]
[SIZE=2][Mega cam] -[/SIZE]
[SIZE=2][Sensor] -[/SIZE]
[SIZE=2][Touch] -[/SIZE]
[SIZE=2][Sleep] - sleep mode (power button) test[/SIZE]
[SIZE=2][Speaker] - listen![/SIZE]
[SIZE=2][Sub key] - testing keys [/SIZE]
[SIZE=2][Front cam] - [/SIZE]
[SIZE=2][IR LED] - Samsung TV compatible IR remote control[/SIZE]
[SIZE=2][LOW FREQUENCY] - Listen 100/200/300 Hz[/SIZE]
[SIZE=2][Black] - screen darkness test[/SIZE]

<E> = A "Dead End" that take you into an oo-loop page or back
to a locked *#0011# state.
(a) For accessing this sub-menu you may need to:
1. Unblock the KeyString file with:
echo -n "OFF" > /efs/FactoryApp/keystr
2. Enable the carrier HiddenMenu file with:
echo -n "ON" >/efs/carrier/HiddenMenu
3. Set the device shipping property: ro.product_ship=FALSE
(b) For "FTM" (Factory Test Mode) you probably need to set:
1. Enable the FactoryMode file with:
echo -n "ON" >/efs/FactoryApp/factorymode
2. Set the factory test property: ro.factorytest=1
(c) Not available for non-DOCOMO devices, need correct property(ies).

Some Useful Examples
Example-1: Removing SIM network lock
Code:
[SIZE=2]UMTS MAIN MENU[/SIZE]
[SIZE=2][1] DEBUG SCREEN.[/SIZE]
[SIZE=2][6] PHONE CONTROL.[/SIZE]
[SIZE=2][6] NETWORK LOCK[/SIZE]
[SIZE=2][3] PERSO SHA256 OFF[/SIZE]
[SIZE=2]Go Back to Main Menu[/SIZE]
[SIZE=2]UMTS MAIN MENU[/SIZE]
[SIZE=2][6] COMMON[/SIZE]
[SIZE=2][6] NV REBUILD.[/SIZE]
[SIZE=2][4] Restore Back-up.[/SIZE]
[SIZE=2]Reboot[/SIZE]
This has not been tested by me, since I don't use SIM locked providers.
So make sure you have a complete NANDroid backup of your phone in case something
goes wrong. I do not take any responsibility for damaged phone due to this procedure.
Please confirm if this method works for this phone.

How to trigger the Nfc Test application?
Package name is com.sec.android.app.nfctest.
Decompiled NfcTestBroadcastReceiver.java file:
Code:

import android.net.Uri;
import android.nfc.NfcAdapter;
import android.util.Log;
// Referenced classes of package com.sec.android.app.nfctest:

Tried the secret code *#6328378# in phone dialer but nothing happened.
Update:
But it works from commandline:
Code:
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://6328378

Great Job! Thanks. BTW. "6328378" = "NFCTEST".
also see if there are some other related files in /efs/ that need to be "enabled".
Make sure to backup you EFS folder, and don't try to add delete files in there, it doesn't work as a normal directory... EFS is more like a solid part of memory. You can change values, but not the number of values (size).

Yeah, not sure what they did, but you can play with the other properties, but first try this:
Code:
[SIZE=2]echo -n "OFF" >/efs/FactoryApp/keystr
echo -n "ON" >/efs/FactoryApp/factorymode
echo -n "ON" >/efs/carrier/HiddenMenu
[/SIZE]
(You may also need to chmod these files before changing. And don't forget to change back after your done playing. It could be that factory mode disables some network functionality.)
Second, all the codes I mentioned in OP, are normally entered by "*#<code>#*", but some phones require this: "*#*#<code>#*#*" before working, so try that as well.

PreConfig application can be started using following command:
Code:
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://83052020100812173552301071192687

Serial number, FCC ID and logo screen:

So im on att currently and had not been happy with the lack of lte due to this being a verizon branded phone (hspa+ was getting me 4.5 mbps at best ,which I owe major thanks to this thread for even getting me that far ) so after tearing through stacks of codes listed in the android manifest xml files attached to he system keystring apps and such (many of which I couldnt get to do much of anything ) I found one that I havent seen listed that goes Into some ims and lte functions which got me 11.5-12+ mbps ranges pretty darn consistantly. The hiddenkeystring for me is ( *#467# ) I am not saying these are great lte speeds but quite a bit better than I was pulling down before and as I said quite consistantly. Hope this helps
oh also I forgot to mention also gives some nice choices for native flash media as well as some various codecs for audio. oh and some tethering options kindof nice as I had recently lost the ability to hotspot and couldnot find a workaround app that was successful. Dam one other set of options regarding the e-9 won won stuff as far as the network I guess maybe

That doesn't work for the 9195, although they seem very similar.
What's your stock ROM and MODEM FW? Perhaps some getprops please.
@dp929 Can you post a screenshot?

Does anyone know how to stop the fm radio from asking for headphones?
I know it uses it as antenna but with an older samsung phone I disabled it, I just don't remember how, and the reception wasn't that bad
thanks

Thanks sir for the suggestions. I can see I've included the descriptions for most of them already, but I'll be sure to attribute to and add the rest tomorrow. I would be grateful if you could shed some light on the ones I've marked "NEED HELP"

I've done those stuff offline from your gist[emoji14]have seen this thread after that but maybe you like the way i showed the defines as it's setup the way you would do in your BoardConfig.mk.
Haven't done those flags i am not sure about myself, maybe @_that or @Dees_Troy can bring light to some of them.
Gesendet von meinem LG-H815 mit Tapatalk

This thread is a great idea.
Especially with the update to twrp 3.0 with new flags.
I've been lucky enough to be able to guess/puzzle out/grab from other device trees enough to build and use the recovery on my personal devices, but information like this is very helpful to have consolidated.
Thanks for sharing.

Yeah, I just didn't have enough time to beautify it. Will gradually do so.

TW_CUSTOM_THEME := /path/to/theme/
this one is used to replace the stocktheme with a different one (like material-play)
the theme will be directly in ramdisk
TW_INCLUDE_INJECTTWRP := true — adds ability to inject TWRP into some Samsung boot images for Samsung devices that have recovery as a second ramdisk in the boot image
the second flag is quotes by dees_troy!
TW_NEW_ION_HEAP
this has sonething to do with 3.10 kernels and a different naming in /include/linux/ion.h ... like a switch between old heap_mask and new heap_id_mask
Sent from my Xperia T using XDA Free mobile app

Nice initiative with this thread, this has been oh say 2 years too long in the making haha.
TARGET_RECOVERY_FORCE_PIXEL_FORMAT
Not sure but I would imagine it overrides what TWRP detects nor do I see the difference between it and TARGET_RECOVERY_PIXEL_FORMAT. The only possible varible right now is RGB_565. BGRA_8888, RGBA_8888 and RGBX_8888 are not yet implemented.
TW_INPUT_BLACKLIST
Black list input devices that interfere with touch. For multiple input devices the delimiter is \x0a. You would basically build a special TWRP with TWRP_EVENT_LOGGING := true. Put it on the device and read the more verbose log to see what inputs you want to blacklist.
EDIT: Ah here is a copy of the wording I had in one of my xda posts about the subject and the commit link https://github.com/omnirom/android_bootable_recovery/commit/5742a40b87dfdc26df3bd9fe94197ae414ece546
Usage:
TW_INPUT_BLACKLIST := accelerometer
TW_INPUT_BLACKLIST := "accelerometer\x0agyroscope"
This can be used to fix touch input on devices where an input
device is breaking touch processing in TWRP.
We are using new line chars to separate multiple devices and in
the make file you specify the new line character with \x0a which
is the hex code in ASCII for a new line.
The new line character might be a bit of a pain to use as a
delimeter, but it is highly unlikely that an OEM will ever name
an input device with a new line character in the name.

On a side note is there a link somewhere to fixing graphics issues induced in 3.0? I see a lot of talk about it but nothing substantial.

Not really. Slanty graphics can be fixed with linelength, but as such there's nothing on that front. You might wanna slap a recovery.log onto Dees_Troy at #twrp on webchat.freenode.net though.

Every version has new flags introduced & also flags deprecated...
TARGET_USES_LOGD => Source
TW_SCREEN_BLANK_ON_BOOT ( Deprecated on android-6.0 => Source, on some legacy devices, TWRP will not boot without this flag)
Dees_Troy said:
There are other build flags which you can locate by scanning the Android.mk files in the recovery source. Most of the other build flags are not often used and thus I won't document them all here.

Download the script & extract it to your HOME or if you are 100% sure that you have already setup a fully working Build Environment on Ubuntu or any other linux distro then remark these lines.

BBQLinux => Menu => Administration => BBQLinux Python Switcher => Python 2
BBQLinux => Menu => Administration => BBQLinux Java Switcher => OpenJDK 7
Start the script with below command
Code:
sh twrp
Menu 1
You can use either OmniROM or Cyanogenmod repo to build TWRP
Choose either to use TWRP branch android-5.1 or android-6.0. Typically, for legacy devices with ICS or JB doesn't support TTF so if TWRP android-6.0 doesn't boot then you'll have to use android-5.1 branch.
You can either choose to use Full-Source or Part-Source. Compiled out recovery.img will have exactly the same size & files on ramdisk.
Yes, Part-Source is only using 41 of the projects to build a fully working TWRP. Syncing in progress. After syncing, you can refer to ~/AIO-TWRP-Compiler/sync.log for any error
Typically, when you have already downloaded the base repo, re-syncing it will only take a few seconds
Menu 2
Copy either your boot or recovery.img to ~/AIO-TWRP-Compiler folder
Key-in your vendor name
Key-in your device name
This step is extracting the ro.product.device & ro.product.model from your device directly which is typically require for identification when flashing update.zip from your vendor
Credits to RD osm0sis, the script will auto download osm0sis's unpackbootimg for mkbootimg arguments required for repacking recovery.img . . . :good:
mkbootimg arguments will be display & auto updated to the BoardConfig.mk
Part of the original mkvendor.sh script is adapted for the extraction of boot or recovery.img which also does the git initialization. If the ramdisk can be unpack then the recovery.fstab will be copied to the device tree folder, if not then it will create a basic MTK recovery.fstab, boot.mk & also BOARD_CUSTOM_BOOTIMG_MK. If you're not building for MTK then remove that line from BoardConfig.mk
You will need to add/ remove TWRP flags accordingly & manual edit on the TARGET_CPU_VARIANT either cortex-a7 or cortex-a9 for older MTK, refer to your device spec. Possible values are cortex-a5, cortex-a7, cortex-a8, cortex-a9, cortex-a15, krait, scorpion. Use generic for devices that do not have a CPU similar to any of the supported cpu variants
You will need to manual edit on the recovery.fstab to suit your device or TWRP-ify the extracted stock recovery.fstab
Menu 3
omni.dependencies is only a warning, will continue to build when you choose OmniROM repo
Make 4.1 is only a warning, will continue to build
Java 1.7 is only a warning, will continue to build
When you have build earlier, subsequent build will only take few minutes bcos of CCACHE... :good:
Menu 4
Updated Menu 4 support for Others. Or you can use Flashify or Rashr or above Others to install compiled recovery.img to your device, do check if they are compatible or it will brick your recovery or worse, whole device !
Key-in your device recovery partition path. Above is typical for LG
Done, test TWRP on your device to make sure it is working properly if not then add or remove flags accordingly & use Menu 3 to build again
Menu 5
Choose either Option 1 or 2, Option 2 is recommended & it won't take long if you are using Part-Source.
Menu 6
The script will auto open up a new browser for you to register a new account on github
Your device tree on github

bash script itself is self-explanatory. Thanks to the OP, he has offer to take over the maintenance of this script so hit your Thanks button to him... :good: If you found any error/ bug or have any new ideas/ features for this script then pm the OP or do a git pull request... :good:
Above is the detail explanation on the script GUI front-end, here i'll explained what the script actually does.
Menu 1
This menu will create a local_manifest.xml to remove unwanted projects based on your selection. When select Full-Source, it will also create local_manifest.xml to remove existing recovery & replace it with TWRP based on your selection.
Code:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<remove-project name="android_bootable_recovery" />
<project path="bootable/recovery" name="omnirom/android_bootable_recovery" revision="[COLOR="Blue"]android-6.0[/COLOR]" />
</manifest>
Part-Source
It is normal that OmniROM & CM will consistently add new projects to their repo when they introduce new features or functions to it. The beauty of this Part-Source is that even when projects grows, this script will grep -v only the needed projects for building TWRP on any base repo.
This Part-Source is the extreme minimal for building TWRP therefore some of the additional projects are needed when you use particular TWRP flags. As of today ( March 2016 ), it will build a fully working TWRP with only 44 projects on both OmniROM 4.4 & CM 11 base repo. In the future, Teamwin may also add a new feature or function then you will also need to add additional projects to it too or OP will update it based on your feedback. Refer to compile.log for details.

This script has been tested & it works on any base repo from OmniROM android-4.4, 5.0, 5.1 & 6.0 & Cyanogenmod cm-11.0, cm-12.0, cm12.1 & cm13.0 using Full-Source or Part-Source but why use Full-Source to build TWRP when Part-Source works, most importantly, you are not building OmniROM or Cyanogenmod but TWRP.... Using android-4.4/ cm-11.0 base repo has its advantage, compiled TWRP size will be smaller & it can build all version.
If you use android-6.0/ cm-13.0 then obviously you can only build TWRP android-6.0 only, just edit the line 62, 63 for OmniROM or 72, 73 for CM accordingly. Building TWRP android-4.4 on cm-13.0 or on OmniROM android-6.0 will result in a build error ! Later base repo won't build TWRP older version !
Many newbies doesn't know that OmniROM/ CM repo are incremental updates & they create a separate cm11, cm12, cm12.1, cm13 each & sync individually to each of these folders.
Above syncing cm-13.0 & as you can see, it is also using source from cm-10.1, 10.2 & 11. Syncing all to the same ~/omni or ~/cm folder will do.
Sometimes on certain devices, OmniROM android-4.4 or Cyanogenmod cm-11.0 base repo just won't boot then you can try by editing this line to android-5.0 or cm-12.0 & updating it will only take a very short time if you use Part-Source.
Menu 2
Device tree
This script will create a barebone minimal device tree for building TWRP. Anything less will result in a build error. It will create five files which is just sufficient to build a fully working TWRP using prebuilt kernel. It will build kernels too, just update the correct kernel config to BoardConfig.mk & remove the remark # needed projects for building kernels. However, i don't see the needs to build the same kernel with every TWRP new build, it will take a longer time to build, most importantly, you are not building a ROM.

My TWRP-ify recovery.fstab. Typically, for ext4 partition, you don't need to specify flags=display= & backup=1, it will be taken care of by TWRP, for more info regarding fstab flags then refer to Main Thread for *RECOVERY.FSTAB*... :good:
RD osm0sis's unpackbootimg is able to extract --second <2ndbootloader-filename> & also --second_offset <address>
The repack arguments will be auto-updated to the BoardConfig.mk Thanks to RD osm0sis. Some TWRP flags ref taken from here... :good:
osm0sis's unpackbootimg also support --dt <filename> :good:
Some devices require additional info for factory update.zip then add it accordingly to the device tree, typically is your device_(device-name).mk. Look at other device tree here & here & here for reference. On CM base repo, you can also use mkvendor.sh... :good: However, you will need to manually edit certain files as no DEV has been updating it, currently it will result in a build error even when using Full-Source !
Do take note that even an extra space on some of the lines at BoardConfig.mk will result in a build error !
Menu 3
Below are the commands to build TWRP, thats it !
Code:
cd ~/omni
[COLOR="blue"]OR[/COLOR]
cd ~/cm
prebuilts/misc/linux-x86/ccache/ccache -M 25G
export USE_CCACHE=1
export LC_ALL=C
source build/envsetup.sh
lunch [COLOR="blue"]omni[/COLOR]_S939-eng [COLOR="blue"]<= S939 is the device name[/COLOR]
[COLOR="Blue"]OR[/COLOR]
lunch [COLOR="blue"]cm[/COLOR]_S939-eng
make -j4 recoveryimage
Menu 4
Below command generically will work on most Android devices. Updates : Has updated this menu to support this, just key-in /path-to-your-device-recovery-partition
Code:
adb push [COLOR="blue"]$OUT[/COLOR]/recovery.img /data/local/tmp
adb shell su -c "dd if=/data/local/tmp/recovery.img of=/[COLOR="blue"]path-to-your-device-recovery-partition[/COLOR]"
To use the $OUT path, you must first source it then lunch your device name, refer to previous Menu 3 for info.
Menu 5
Option 1 is make clean
Option 2 is wipe the whole repo base folder except the hidden .repo folder. As mention on the script GUI front-end, after that, use Menu 1 will have all the files extracted out.
Menu 6
This menu is using curl to create github repo.
It is for you to publish your device tree either for diagnostic & debugging when you ask for help. It is also for you to share a working build so that others can refer to it when they make a build of their own or git clone yours & build it themselves.

Preface & Credits
Many newbies make mistake by using other DEV's device tree which is normally meant for building ROMs, using it to build TWRP therefore will result in alot of build errors !
Above script can also be use to build TWRP for any Android devices that uses standard Android header, except for Menu 4 which is specifically for MTK devices only. Just edit the script to add support for your device... :good: Updated support for other devices
This project was actually started way back at 2013 & this is the main reason why TWRP doesn't build is bcos of the tedious, confusing & wrong Build Environment setup, it is all so different on so many different linux distros & OSes version, i went on to developed Easy Magic TWRP.... Now i use Intel device & this script did build a working TWRP for it too.... :laugh:
That's why i strongly recommends BBQLinux for beginners, Thanks to RD codeworkx, i can guarantee that any Build Error is not cause by wrong BE setup as its already built-in on BBQLinux... :good:
The other reason TWRP doesn't boot is bcos of wrong mkbootimg repack arguments, Thanks to RD osm0sis for his awesome unpackbootimg... :good:
Since many newbies are having problems with building TWRP & flooding the TWRP thread here

Which is actually meant for intermediate users, i've offered to share this script when OP decided to open up a new thread here for TWRP flags.... :good:
Credits Updates
Hacker432 for testing & feedbacks on this script, now it uses the ATC folder so that it'll support other languages other than English & TWRP will boot now when build on cm-12.1 base repo... :good:
OP for giving this script a glamour name ATC aka AIO-TWRP-Compiler... :laugh: :highfive: :good:
My TWRP doesn't boot
Try unpack/ repack your stock 3e recovery.img with AIK, push it to your device & if it doesn't boot then obviously your device is not using standard Android header & so does this script will not build a bootable TWRP. Try google your device info on how they did it, Eg. Sony devices uses BOARD_CUSTOM_BOOTIMG_MK for repacking boot & recovery.img & update it accordingly to your BoardConfig.mk
Code:
adb shell cat /proc/last_kmsg
[COLOR="Blue"]OR[/COLOR]
adb shell cat /proc/last_kmsg > kmsg.txt

Extreme minimal, TWRP require this only one flag TW_THEME := to build or it will error out. You will also need other flags as well, refer to the OP. Some devices won't boot when certain TWRP flag is used or not used bcos its not compatible with your device kernel ! Most legacy device doesn't support TTF & TWRP won't boot so you have to build with TWRP android-5.1 with TW_DISABLE_TTF := true flag
Code:
[URL="https://github.com/TeamWin/android_device_kazam_thunder_q45/blob/cm-10.2/BoardConfig.mk#l49"]TW_NO_EXFAT := true[/URL] [COLOR="Red"]<= To disable exfat[/COLOR]
[URL="https://github.com/TeamWin/android_device_kazam_tornado_348/blob/android-4.4/BoardConfig.mk#l50"]TW_NO_EXFAT_FUSE := true[/URL] [COLOR="Red"]<= To disable exfat[/COLOR]
[URL="https://github.com/carliv/device_elephone_p6000/blob/cm-11.0/BoardConfig.mk#l110"]TW_USE_TOOLBOX := true[/URL] [COLOR="red"]<= Using this flag will use toolbox instead of busybox[/COLOR]
Above are some of the flags that can cause TWRP not to boot up. If you are using Part-Source then you need to add additional projects to support these flags as most of them are disabled on the script. Just remove the remarks # from the script for that particular projects. More detail info refer to above post #11 Part-Source.
Refer to the most bottom Bug Report on how to obtain recovery.log, without it nobody is able to help you.
Code:
[URL="https://github.com/omnirom/android_bootable_recovery/blob/android-6.0/minuitwrp/Android.mk#l122-l130"]TARGET_RECOVERY_PIXEL_FORMAT := ABGR_8888[/URL]
TARGET_RECOVERY_PIXEL_FORMAT := RGBX_8888
TARGET_RECOVERY_PIXEL_FORMAT := BGRA_8888
The other reason it doesn't boot is that it actually does boot up but the screen is blank ! Try adb shell & it should work on this scenario.
Try different pixel format one at a time, one of them should work.
Code:
[URL="https://github.com/omnirom/android_bootable_recovery/blob/android-6.0/minuitwrp/Android.mk#l114-l116"]TARGET_RECOVERY_FORCE_PIXEL_FORMAT := RGB_565[/URL]

[URL="https://gerrit.omnirom.org/#/c/13948/"]TW_DISABLE_DOUBLE_BUFFERING := true[/URL]
When not setting any pixel format, the default is RGB565 & it should work on most Android devices. You can also try the above when non of them works.
Code:

Miscellaneous Tips
As mentioned many times, most of the time build error is bcos of wrong BE setup, use BBQLinux & you'll get over it. If you have already build on other distro then refer to here on how to use this script or migrate the source code .repo to BBQLinux.

TWRP has everything specified to standard Android path unless when it doesn't work then you'll need to find that out yourself. Do take note that some device doesn't support certain feature such as CPU temperature, battery level, mount USB storage & etc then refer to the OP for flags to disable it.
Code:
adb shell su -c "ls -R" > [COLOR="Blue"]myAndroid.txt[/COLOR]
Above command will list out everything on your device.
Code:
adb shell su -c cat /sys/class/power_supply/battery/capacity
[COLOR="blue"]88[/COLOR]
Eg. Say the battery capacity doesn't work then look for that path at myAndroid.txt for something that says battery/capacity & specify it at BoardConfig.mk
Code:
adb shell cat /sys/class/thermal/thermal_zone0/temp
[COLOR="Blue"]27516[/COLOR]
If CPU temperature doesn't work then look for thermal/temp
Code:
adb shell
su
echo 0 > /sys/devices/platform/i2c-gpio.24/i2c-24/24-002c/backlight/lcd-backlight/brightness
echo 255 > /sys/devices/platform/i2c-gpio.24/i2c-24/24-002c/backlight/lcd-backlight/brightness
If brightness doesn't work, look for lcd-backlight/brightness, Eg. above command should be able to change the level of brightness if that is the correct path as indicated at myAndroid.txt.
Sync corruption
git & repo is like a Super Intelligent Source Code Auto-Resume Downloader when working together . . . :good:
You can stop it at any time, restart it back & it will auto-resume. cm repo & source code is located at ~/cm/.repo, omni at ~/omni/.repo it is a hidden folder & to view hidden folder via File Manager, you need to press Ctrl + h
Sometimes you have corruption then repo sync wouldn't work & normally you just need to delete manifests, manifests.git, manifests.xml with a repo init & repo sync then you'll be back to normal.
If still this doesn't solve the problem then delete everything EXCEPT the folder project-objects & projects, both of this is the actual source code folder.
After this a repo init then repo sync & everything will be back to normal, i guarantee, done this many times, no worries . . . :laugh:
Sometimes when you have severe data corruption, above technique will not work then manually cd ~/cm or ~/omni then repo init then repo sync & see what repo & git has to say then follow the on-screen instructions to remove the corrupted projects.
Scroll back up & see what the error was, remove the corrupted project then repo sync. In this case is rm -rf ~/cm/.repo/projects/prebuilts/clang/linux-x86/host/3.5.git
Subsequent sync show above error. rm -rf ~/cm/.repo/project-objects/CyanogenMod/android_external_icu.git
rm -rf ~/cm/.repo/projects/external/jemalloc.git
rm -rf ~/cm/.repo/projects/system/extras/su.git
rm -rf ~/cm/.repo/projects/external/libcxx.git
rm -rf ~/cm/.repo/projects/external/libcxxabi.git
rm -rf ~/cm/.repo/projects/external/libunwind.git
rm -rf ~/cm/.repo/project-objects/CyanogenMod/android_external_busybox.git
And finally all corrupted projects has been removed, subsequent repo sync & all files will be auto-extracted out.
Corrupted .repo folder
i've make a back up of my .repo folder using tar.gz compression years ago & when extracting out, normally will end with data corruptions except if you use lrzip... :good: You will need to manually remove all the text files such as hooks, pre-auto-gc & commit-msg which is supposed to be a symlink files.
After you force overwrite extraction, a repo init & repo sync will end with above message.
You will need to manually delete all the hooks.txt file found at .repo folder
You will need to manually delete all the commit-msg.txt file
You will need to manually delete all the pre-auto-gc.txt file. You might need to repo sync --force-sync many times to overwrite all the corrupted projects & after that, you won't be getting any of these error messages again.
Syncing work tree error - Doesn't check out all files
This operation must be run in a work tree
Run the below command will give you hint
Code:
repo --trace sync -l
Above hints the corrupted projects so remove it => rm -rf /home/yuweng/cm/.repo/projects/frameworks/ex.git
repo sync still it doesn't extract out all the files so you need to run repo --trace sync -l again. Delete the hinted project => rm -rf /home/yuweng/cm/.repo/projects/frameworks/webview.git
When all error has been fixed, a repo sync & all the files will be extracted out correctly

TWRP FAQ

@yuweng the script has really been thought over for a long time and you also have put in tons of work in it. Thanks for it man!

Thanks bro... :highfive: The script initially includes BE setup for Ubuntu that includes setting up of Python, Java, Make, Git, build packages, adb rules & etc, now its half the size bcos we don't need to do all that on BBQLinux... It has went thru alot of revision, i lost track, one has PhilZ Touch on it, one revision will detect the device info such as graphics resolution, emmc or /data/media device & etc, you can actually do wonders with adb shell, automated alot of stuff for BoardConfig.mk, all in all, this script has about 4 years of work in it...

4 YEARS!!!! @Dees_Troy, @bigbiff, @_that this guy deserves a medal! And about the BE Setup, my good friend @thewisenerd had made an Android compiler which included a rather fancy dependencies check in a python program. I'll include it into AIO-TWRP-COMPILER as soon as I finish my school work for the week

Haha, they are all my Master Shifu's & they all have more experience than me on TWRP... :laugh: You are most welcome to add-in new features to it... :good:

Experience?? They're encyclopedias on TWRP. But it's worthless if every humbug on the planet wants to compile it and doesn't even know what "ls -R " is supposed to do You're being a great help to everyone. I'll try and get them to try this when I can make it compatible for people who have already downloaded the source

Actually its quite easy but then again any wrong BE setup will result in build error that's why i strongly recommends BBQLinux for starters, its as easy as Ubuntu to setup, i can guarantee many will like the UI, Thanks to RD codeworkx.... :good:

Updates - Migrating source code .repo to BBQLinux
So far my experience is that only lrzip is able to compress & extract source code .repo folder without data corruption... :good: Just open Ubuntu Nautilus File Manager & delete everything on your cm or omnirom except the hidden folder .repo
This hidden .repo folder is where the actual source code are, zipping it will be enough for migration, a repo init & repo sync will have all the files extracted out on BBQLinux ...
Code:
sudo apt-get install lrzip

LiME - Loadable Kernel Module (LKM)

Hi guys.
I have been trying to dump the memory ram of a Galaxy S5 (Au version).
I have a problem on the final step.
When I try to run insmod, it reports as follows:
insmod lime.ko “path=tcp:9999 format=lime”
insmod: init_module 'lime.ko' failed (Function not implemented)
The phone details:
- Galaxy S5
- Android version 5.0
- Baseband version: G900IDVU1BOJ2
- Chipset: MSM8974PRO-AC
I am using two platforms of Linux , neither of them work, (Kali Sana 2.0 and Ubuntu 15.10 Willy)
The version of the tools are as follows:
- Java = java-8-openjdk-amd64
- NDK = android-ndk-r11c
- SDK = Android Studio 2.0
- Cross Compiler = arm-linux-androideabi-4.9 (It comes with NDK) and I have tried with arm-eabi-4.6
The phone does not contain the /proc/config.gz, instead I found on the Samsung's website two versions for the same chipset in Australia, but neither with the same baseband (I don not if that affects). So the generate .config using the code source I ran:
make msm8974_sec_defconfig VARIANT_DEFCONFIG=msm8974pro_sec_klte_eur_defconfig SELINUX_DEFCONFIG=selinux_defconfig
#
# configuration written to .config
#
The makefile for Lime that I have been using is:
obj-m := lime.o
lime-objs := main.o tcp.o disk.o
KDIR_GOLD := /home/osboxes/workspace/Kernel
KVER := $(shell uname -r)
PWD := $(shell pwd)
CCPATH := /home/osboxes/workspace/arm-eabi/arm-eabi-4.6/bin
default:
# cross-compile for Android emulator
$(MAKE) ARCH=arm CROSS_COMPILE=$(CCPATH)/arm-eabi- -C $(KDIR_GOLD) M="$(PWD)" modules
$(CCPATH)/arm-eabi-strip --strip-unneeded lime.ko
# compile for local system
$(MAKE) -C /lib/modules/$(KVER)/build M="$(PWD)" modules
strip --strip-unneeded lime.ko
mv lime.ko lime-$(KVER).ko
$(MAKE) tidy
tidy:
rm -f *.o *.mod.c Module.symvers Module.markers modules.order \.*.o.cmd \.*.ko.cmd \.*.o.d
rm -rf \.tmp_versions
clean:
$(MAKE) tidy
rm -f *.ko
I appreciate any help in this matter.
PS. I will be trying more options

Musl is patched (info)(info2)(patch file: patch -p0 -u -b -i musl-android-smp.patch) to iterate CPU cores by /proc/stat instead of _SC_NPROCESSORS_CONF/sched_getaffinity to prevent false detection due to ARM cpu core powersaving (permanently turning cores on/off). This should report CPU cores more reliably to multithreading apps.
Example instructions how to build EncFS can be found here.
Some Cryptsetup compile recipes are here.

Data recovery tools:
- PhotoRec 7.2 - PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted.
- Testdisk 7.2 - Recover lost partitions and partition tables. For external sdcards. Never use it on internal mmc unless you know what you're doing.
- ext4magic 0.3.2 (with supplementary gnu date binary that can handle relative time like 'date -d "-20minutes" +%s')
- fidentity - A little utility sharing PhotoRec signature database. It identifies the type of data contained in a file and reports the extension as seen by PhotoRec.
- debugfs - Might be helpful on ext2 systems or other stuff.
- strace 4.20 - For debugging. Mainly to catch syslog messages (as Android has no traditional /dev/log buffer).
- strace 5.6 - For aarch64.
- ddrescue v1.25 - Data recovery tool for block devices with errors.
Compression tools:
p7zip v17.01 (fork) - (Download) A new p7zip fork with additional codecs and improvements
pixz - Parallel, indexed xz compressor
xz - Multicore aware version of xz/lzma (use --thread=0)
tar v1.32 - Tar provides the ability to create tar archives, as well as various other kinds of manipulation. Download below. More builds from @mirfatif here.
fxz - (Download) FXZ Utils is a fork of XZ Utils. It adds a multi-threaded radix match finder and optimized encoder.
Misc:
- hexcurse v1.60.0 - Hexcurse is a curses-base hex editing utility that can open, edit, and save files, editing both the hexadecimal and decimal values. 'ncurses' ui layout depends on TERM env variable. Change temporary with eg. 'TERM=xterm-256color hexcurse <file>'. See /system/etc/terminfo for possible terminals (xterm-256color, linux..).
- nethogs v0.8.5 - ncurse/nettop-like per-app separated speedmeter and traffic counter supporting high refresh rate. Try 'nethogs -d0' (speedmeter) or 'nethogs -v1' (traffic counter).
- rsync v3.2.3 - rsync is an open source utility that provides fast incremental file transfer. (--with-rsyncd-conf=/data/etc/rsyncd.conf)
- smbnetfs v0.6.1 - SMBNetFS is a Linux/FreeBSD filesystem that allow you to use samba/microsoft network in the same manner as the network neighborhood in Microsoft Windows. More info see below.
- progress v0.14 - Linux tool to show progress for cp, mv, dd, ... (formerly known as cv). Download here.
- archivemount (20180801) - A fuse filesystem for mounting archives in formats supported by libarchive. Download here.
- squashfuse v0.1.103 - FUSE filesystem to mount squashfs archives Download here.
- FuseISO - FuseISO is a FUSE module to mount ISO filesystem images (.iso, .nrg, .bin, .mdf and .img files). It currently support plain ISO9660 Level 1 and 2, Rock Ridge, Joliet, and zisofs. Download here.
- HSTR v2.2.0 - HSTR (HiSToRy) is a command line utility that brings improved Bash/zsh command completion from the history. It aims to make completion easier and more efficient than Ctrl-r. (If history is empty try setting HISTFILE in /system/etc/bash/bashrc e.g. export HISTFILE=/data/.bash_history).
- GNU screen, tmux - Thanks to @mirfatif.
- dislocker, ntfs-3g, mount.exfat-fuse - Thanks to @mirfatif.
- f2fs-tools - Thanks to @mirfatif. Update: v1.14.0 here.
- parted v3.3 - GNU Parted (the name being the conjunction of the two words PARTition and EDitor) is a free partition editor, used for creating and deleting partitions. Note: It might be useful to partition external sdcards (e.g. to limit adoptable storage). I do not recommend to use it on internal memory. It might brick your phone.

Crypttools:
(These crypttools are mostly frontend tools for the main backend that resides in the kernel. If your kernel hasn't been configured accordingly at compile time you might not be able to use all features.)
Cryptsetup v2.3.5 - (Download) Cryptsetup is an utility used to conveniently setup disk encryption based on DMCrypt kernel module. These include plain dm-crypt volumes, LUKS volumes, loop-AES and TrueCrypt (including VeraCrypt extension) format.
eCryptfs-utils v111 - Frontend tools for the enterprise cryptographic filesystem for Linux. That's what Android/Google use for encryption. It's file-based (no container) and mounting can be automated by Termux widget. Needs shared libraries but is still portable. See notes below.
EncFS v1.9.5 - EncFS provides an encrypted filesystem in user-space. It runs in userspace, using the FUSE library for the filesystem interface.
gocryptfs - An encrypted overlay filesystem written in Go. Download here. Thanks to @mirfatif.
VeraCrypt - VeraCrypt is a free open source disk encryption software. Download here. Thanks to @mirfatif.
fscrypt 0.2.7 - (Download) fscrypt is a high-level tool for the management of Linux filesystem encryption. Needs at least kernel 4.1.
Crypttools info:
Cryptsetup:
General Notes:
- Features like TrueCrypt, VeraCrypt and LUKS2 need 'userspace crypto api' enabled in kernel. Most Android kernels are probably not configured for that and you have to recompile your kernel or contact your kernel maintainer. For kernel 3.4 you need this:
Code:
CONFIG_CRYPTO_USER=y
CONFIG_CRYPTO_USER_API=y
CONFIG_CRYPTO_USER_API_HASH=y
CONFIG_CRYPTO_USER_API_SKCIPHER=y
- If 'cryptsetup benchmark' is incomplete and says 'userspace crypto api not available' you might be affected. You can still use LUKS1 though. A full benchmark looks like this:
Code:
# cryptsetup benchmark
# Tests are approximate using memory only (no storage IO).
PBKDF2-sha1 249186 iterations per second for 256-bit key
PBKDF2-sha256 327680 iterations per second for 256-bit key
PBKDF2-sha512 58829 iterations per second for 256-bit key
PBKDF2-ripemd160 227555 iterations per second for 256-bit key
PBKDF2-whirlpool 33539 iterations per second for 256-bit key
argon2i 4 iterations, 208288 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time)
argon2id 4 iterations, 207817 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time)

LUKS:
Code:
** 10MB test image (luks.img) **
dd if=/dev/zero of=luks.img bs=1M count 10M
cryptsetup luksFormat luks.img
cryptsetup open luks.img myluks
mke2fs -t ext4 /dev/mapper/myluks
mkdir luks
mount /dev/mapper/myluks luks
** luks folder is ready here **
umount luks
cryptsetup close myluks
- If standard luksFormat cipher (aes-xts-plain64) doesn't work (not supported by your kernel) you can try one of the more compatible ciphers:
Code:
cryptsetup luksFormat -c cbc-essiv:sha256 luks.img myluks
cryptsetup luksFormat -c aes-plain luks.img myluks
- For LUKS2 (experimental) use:
Code:
cryptsetup luksFormat --type luks2 luks.img
- Use "cryptsetup -v --debug" for more verbose output (debugging). In case of errors.
Veracrypt:
Code:
cryptsetup open --type tcrypt --veracrypt veracrypt.tc myvera
cryptsetup status myvera
mkdir /data/myvera
mount /dev/mapper/myvera /data/myvera
umount /data/myvera
cryptsetup close myvera
- Use container from desktop system (created with real Veracrypt)
- "veracrypt.tc" is the veracrypt container name
- "myvera" is an arbitrary name (handle)
- Use "cryptsetup -v --debug" for more verbose output (debugging). In case of errors.
eCryptfs-utils:
General Notes:
These tools are not built statically as they explicitly rely on 'dlopen' (plugin system). Instead they are compiled with relative rpaths (./libs). That means dependencies (libraries in subfolders) must be present in the binaries folder and you have to be in the binaries folder itself (with 'cd') before invoking any binary. By this the binaries are still portable (system independent) as long as the subfolders are present. I've put the files into a tar.gz archive so permissions should be set +x already. Extract the archive into /data/local/bin for 'Example' below.
Code:
mkdir -p /data/local/bin
cd /data/local/bin
tar xf crypttools.armv7.20180204.tar.gz
cd ecryptfs
./ecryptfs-stat --help
More info: ArchLinux Wiki
Example:
Tested on /sdcard based on FUSE filesystem. sdcardfs untested. Might need selinux permissive.
We create a folder /sdcard/pics that can be enabled (files present) or disabled (no files present) by a click on a widget button (Termux script) and entering our password. The encryption is done on a per-file basis. The actual files are stored encrypted in /sdcard/efs/pics.
- You might need SuperSU or Magisk Superuser for 'su -mm'. That makes sure that all apps can see the mounted folder (mount namespace separation).
- Busybox needed
- Install Termux and Termux:Widget from F-Droid or Playstore
- Start it and enter:
Code:
pkg upgrade
pkg install tsu
exit
- Create script /data/data/com.termux/files/home/.shortcuts/efs-pics.sh and make sure permissions(700) and owner (take from parent folder) are correct.
Code:
#!/system/xbin/bash
su -mm -c "/system/xbin/bash -c /data/local/scripts/$(basename "$0")"
- Create script /data/local/scripts/efs-pics.sh (770/root):
Code:
#!/system/xbin/bash
set -e
PATH=$PATH:/data/data/com.termux/files/usr/bin
# Necessary because rpaths are relative
cd /data/local/bin/ecryptfs
# /data/myefskey contains the salted key.
# Don't forget to make a backup.
# Without it encrypted data is lost.
function enter_passphrase {
read -p "Enter passphrase: " passphrase
sig=$(printf "%s" "$passphrase" | ./ecryptfs-insert-wrapped-passphrase-into-keyring /data/myefskey -) || exit
sig=$(echo $sig | cut -d "[" -f2 | cut -d "]" -f1)
}
CPATH1="/data/media/0/efs/pics"
CPATH2="/data/media/0/pics"
if ! mountpoint -q ${CPATH2}; then
enter_passphrase
echo ""
mount -t ecryptfs -o ecryptfs_sig=$sig,ecryptfs_fnek_sig=$sig,ecryptfs_cipher=aes,ecryptfs_key_bytes=16 ${CPATH1} ${CPATH2} || (echo "$(basename "$0") mount failed!"; exit)
./keyctl clear @u
echo "$(basename "$0") mount successful! :)"
else
umount ${CPATH2} || (echo "$(basename "$0") umount error $? :("; exit)
echo "$(basename "$0") umount successful :)"
fi
# uncomment to force-close Termux window
# killall com.termux
- If your rom uses encryption already (/data/data) beware the './keyctl clear @u' command. It might flush *all* keys in the kernel including the Android encryption one (i'm not sure). This might lead to unpredicted behavior. Either comment it out (then your once injected key remains in the kernel keystore and someone could simply remount your folder without passphrase) or make yourself familiar with the keyctl command and handle it yourself. My phone is not encrypted so i cannot help here.
- Create random keyfile (/data/myefskey) and wrap it with passphrase. This might need 1-2 minutes depending on your devices entropy pool (/dev/random). Backup this key (/data/myefskey). Without it your encrypted data is lost. And don't forget the trailing '-' (minus) at the end of the line, it's important.
Code:
cd /data/local/bin/ecryptfs
read -p "Enter passphrase: " passphrase; printf "%s\n%s" $(busybox od -x -N 100 --width=30 /dev/random | head -n 1 | busybox sed "s/^0000000//" | busybox sed "s/[[:space:]]*//g") "${passphrase}" | ./ecryptfs-wrap-passphrase /data/myefskey -
- Create folders:
Code:
mkdir -p /sdcard/efs/pics /sdcard/pics
- Create Widget (Termux) and select 'efs-pics.sh'.
- Start it and enter your passphrase (you used above). If everything goes well (it will tell you) you can place files into /sdcard/pics and scrambled files should come up in /sdcard/efs/pics. Never write into /sdcard/efs/pics directly.
- Activate widget again. /sdcard/pics should get emptied.
- Optional: You can set /data/media/0/efs/pics to 700/root so no one can access/see the encrypted data.
SMBNetFS info:
Note: The library paths are relative. You need to be in the folder (with 'cd') to spawn the executable (./smbnetfs). You can extract the archive wherever you want though as far as the file/folder structure remains intact.
Example:
Code:
mount -o remount,rw /
mkdir -p /data/local/bin /mnt/cifs
mount -o remount,ro /
tar xf smbnetfs.tar.gz -C /data/local/bin
cd /data/local/bin/smbnetfs
export HOME=/data/local/bin/smbnetfs/home
* enter your smb credentials into smbnetfs/home/.smb/smbnetfs.auth (eg. auth "192.168.1.2" "${user}" "${pass}")
./smbnetfs /mnt/cifs
cd /mnt/cifs/192.168.1.2/${share}
I think it usually should list the samba environment in /mnt/cifs but i'm not sure which prerequisites are necessary for that (edit: maybe it needs real workgroup/hostname instead of IPs). If nothing comes up this should work:
The folder 192.168.1.2/${share} is unreachable by Androids folder picker (unless you can enter the path manually). So either pre-create the folder structure beforehand (mkdir -p /mnt/cifs/192.168.1.2/${share}) and add/register the folder to your app by folder picker (eg. MXPlayer) and then overmount that with the actual ${share}. Or bindmount the folder:
Code:
mount --bind /mnt/cifs/192.168.1.2/${share} /mnt/cifs2
Edit: Another option is to let smbnetfs create a static link (actually a symbolic link) to the share in the mountpoint root (/mnt/cifs). Its not as robust as the bindmount though. MXPlayer doesn't find any files (even though the folder picker shows the folders properly).
Code:
echo "link myfiles 192.168.1.2/${share}" > /data/local/bin/smbnetfs/home/.smb/smbnetfs.host
chmod 700 /data/local/bin/smbnetfs/home/.smb/smbnetfs.host
I've noticed that MXPlayer shows the samba folders just for a glimpse of a second. But if you enter one of the local folders and then go back all samba folders are there. Not sure why this is happening or maybe its just my system.
Edit2: Not yet tested but.. check the permissions. Its possible that SMBNetFS mounts with 755 or something. That's inaccessible for Android apps. Try this:
Code:
./smbnetfs -o umask=000,noatime,noexec,nodev,nosuid /mnt/cifs

Please add ecryptfs-simple
xyne.archlinux.ca/projects/ecryptfs-simple
Thanks.

Ecryptfs-simple is not POSIX compliant. It relies on an argv interface (to parse command-line parameters) that is a GNU extension that musl doesn't support.
The original eCryptFS is simple enough anyway (and its the upstream project). I will provide a quickstart example and a one button GUI controlled solution (Termux widget) to handle it.

Please to add gifsicle,

How does your mount look like?
Code:
# mount |grep pics
/data/media/0/efs/pics on /data/media/0/pics type ecryptfs (rw,relatime,ecryptfs_fnek_sig=56b1f3c519fb3412,ecryptfs_sig=56b1f3c519fb3412,ecryptfs_cipher=aes,ecryptfs_key_bytes=16)
Is /sdcard linked?
Code:
# ls -l /sdcard
lrwxrwxrwx 1 root root 21 May 10 1973 /sdcard -> /storage/self/primary
What Android version and kernel do you have?

Android 6.0 kernel 3.18.14
/sdcard is symlink to /mnt/sdcard, i changed /sdcard to /mnt/sdcard
Code:
# mount -t ecryptfs
/mnt/sdcard/efs/pics on /mnt/sdcard/pics type ecryptfs (rw,relatime,ecryptfs_fnek_sig=1b77138d91206e66,ecryptfs_sig=1b77138d91206e66,ecryptfs_cipher=aes,ecryptfs_key_bytes=16)
Code:
# stat /mnt/sdcard/pics
Access: (775/drwxrwxr-x) Uid: (1000/ system) Gid: (1015/sdcard_rw)
# stat /mnt/sdcard/efs
Access: (775/drwxrwxr-x) Uid: (1000/ system) Gid: (1015/sdcard_rw)
# stat /mnt/sdcard/efs/pics
Access: (775/drwxrwxr-x) Uid: (1000/ system) Gid: (1015/sdcard_rw)
Code:
# touch /mnt/sdcard/pics/test
touch: /mnt/sdcard/pics/test: Permission denied

What about the permissions of /data/media/0 folders? That's the most important part.
If your sdcard is not at /data/media/0 you probably don't have a multiuser environment (older phone?) and /mnt/sdcard is probably a real partition. This is early Kitkat partition layout (/sdcard and /data have separate partitions). On later systems both are on /data partition and /sdcard is abstracted by a FUSE file system that would automatically set the proper permissions whenever you write something to it (even as root).
In case you are on an old layout you would need to set proper permissions to /sdcard/pics and /sdcard/efs yourself. Just take a look at the other folders with 'ls -l /mnt/sdcard' and set accordingly. You would also need to change /data/media/0 to /mnt/sdcard in the script.
What do you get with this?
Code:
# mount |grep sdcard
# mount |grep storage
What phone is it? Kernel 3.18 doesn't sound all too old.
Edit: Another theory is your internal sdcard is scardfs or something. If so, it might break "stacking" folders (mount over). Try to use /data/pics and /data/efs/pics as a test.

It works in Permissive mode (setenforce 0)
I need Busybox with SELinux-enabled and use it to set it to Permissive mode
Code:
# busybox getenforce
Enforcing
# busybox setenforce 0
# busybox getenforce
Permissive
And then execute the efs-pics.sh and test it
Code:
# cp file /mnt/sdcard/pics ; echo $?
[b]0[/b]
# ls /mnt/sdcard/pics
[b]file[/b]
Horreee.... it Works.
