[DEV][Kernel] P5210 | USB RT8187 | Aircrack-ng How to Included

Daniel-TAz00 · Apr 22, 2014

Hi,

This kernel/rom lets you connect an RT8187 USB Wifi adapter to your GT-P5210 and run aircrack-ng/airmon-ng/airodump-ng through Linux on Android.

Mind the noobness, I just compiled my first kernel(ever) and stuck it in someones image and it worked.

(worked untill i enabled the builtin wifi, lol)

After i bought one of these tablets I can't say I'm not a bit dissapointed about the amount of dev work on the GT-5210, (words go unspoken for DutchDanny, Angel_666, trevd)
It's an x86 device, anything should be compileable and runable without any arm mods (i'm looking at you kali linux) this thing should be owning the Nexus 7.

Tested with TWRP 2.7 recovery

Its built using builduntu, and from the P5210UEUAMI8 source, with the toolchain recommended in the Kernel Readme.

I followed this tutorial to enable driver support
And this detailed guide to compile the kernel and create a proper boot.img

Replaced the boot.img in Mod57's rom with my modified one. (god fed up with fastboot and usb issues on Win 8.1 and just flashed it, it worked. Thats my testing)

Mod57 said:
This is built using the Samsung GT-P5210 P5210UEUAMI8 [4.2.2] Jelly Bean base.

This is not debloated it's fat and sassy like Samsung intended it.
If you would like to debloat I highly recommend using DutchDanny's debloater which can be found here:

Once you have downloaded and verified Mod57's rom, open up the zip and replace boot.img with this one:
https://www.dropbox.com/s/9gfucdzsadciy66/boot.zip
MD5: 4dd95a78c78550586cf3c2f7953978ab boot.img

You must have a rooted device (I used TWRP 2.7, http://nasirtech.blogspot.dk/2014/03/root-p5210xxuanb4-android-422-stock.html)

Code:

Put the modified rom onto the sdcard
Go to recovery
Wipe Cache and dalvik-cache
Install the ROM
Reboot and enjoy

Once you have installed the kernel and it boots up, you must follow these steps to chroot into an ubuntu image and compile / install aircrack.

Code:

Download this image: ubuntu-13.10.LARGE.x86.ext2.v1.zip
from [url]http://sourceforge.net/projects/linuxonandroid/files/Ubuntu/13.10/x86/[/url]
and copy it to your sdcard

Thanks to jorgen_gustavsson for his excellent work [url]http://xdaforums.com/showthread.php?t=2573441[/url]

1.  Install busybox [url]https://play.google.com/store/apps/details?id=stericson.busybox[/url]
2.  Install a vnc viewer [url]https://play.google.com/store/apps/details?id=android.androidVNC[/url]
3.  Install [url]https://play.google.com/store/apps/details?id=com.zpwebsites.linuxonandroid[/url]
    (Not sure, but open and close it once to be safe)
4.  Copy bootscript.sh [url=http://xdaforums.com/showthread.php?t=2573441]link to bootscript thread[/url] to /data/data/com.zpwebsites.linuxonandroid/files/ overwrite the old file.
    bootscript.sh
    (Thanks to xdadev: jorgen_gustavsson)
5.  Unpack and Copy the ubuntu-13.10.LARGE.x86.ext2.img and .md5 to a place of your choosing on either internal or external sdcard.
6.  Make a Linux on Android widget and point it to the img file you copied to your sdcard (ubuntu-13.10.LARGE.x86.ext2.v1.img).
7.  Now click on the LOA widget you made in 6 and let linux ”bootup”
8.  Press 'y' to check MD5 checksum 
9.  Connect vnc to localhost:5900 password ubuntu

Now to install Aircrack

Reboot and disable your internal wifi, connect your dongle, and get cracking.

This is what I spent my easter (and then some) doing, I hope someone can make good use of it. I can

Maybe someone can come along and add bcmon for the bcm4334 chipset
(Just maybe https://code.google.com/p/bcmon/source/browse/trunk/bcm4330/driver/src/bcmdhd/Kconfig?r=4 )

Any feedback and questions are welcome:

why didn't you use the latest source? -couldn't find it
Will this kernel work with xx rom? -probably not
Why aren't more roms including this? -dno, its in the menuconfig, should be easy

I've tried to give thanks where ever possible, let me know if you feel left out.
Ill come back tomorrow and clean up my post.

Best Regards

Thank your for your work. This is what I've been looking a long time for.

Please, would you provide a flashable zip of the rom with your kernel? It looks like I'm doing something wrong.
After flashing the modified rom my P5210 just keeps showing the wird boot logo and wont boot up at all.

Thanks in regard!

@Max4000 Do you realize that what Daniel-TAz00 original article is about!
He is showing us a way to run Aircrack-ng in a Ubuntu VNC session with our TAB3 wifi turned off but with a external USB WIFI Dongle!!!!.
He also suggest it will be nice if somebody, created the modification on our own TAB3 10.1 driver sources and compiled it in a new kernel. It was just a suggestion. Then a few commented but no buddy gave the final answer.

I did not follow his steps. I do not even understood why he start with a new TAB3 rom! And a new boot.img. I guess he gave that as a reference as how he did it.
@Jacker31 What is what you are trying to compile, your sources and steps? And what is the exact error?

This is an interested topic to me. But I been sick for more than a week.

Well it have been a long story, I posted a thread about my error, here : http://xdaforums.com/general/help/question-error-2-error-compiling-x86-t3047439 but in the end i found out i used the wrong toolchain. So i redownloaded the correct version and try again. It works but another error popup, its about some Broadcom error. I can successfully compile it after i disabled it in menuconfig. But instead of getting a Zimage i got a Bzimage. So Idk what to do with it. I googled a tones of information but still have no idea what to do with that bzimage. I used Kali Linux to compile and those kernel files are from http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=p5220 GT-P5220_SEA_KK_Opensource. Now i am trying to install builduntu and try to compile it again. Any tips or helps? especially with that bzimage

I get it. He offers a kernel and tells to place it in an flashable zip of an other firmware.
This is not a new firmware, it's just a kernel.

Maybe someone can create a flashable zip of the kernel he has linked to. So I would try to flash it separately.

OHH BOY!

This is Daniel-TAz00 thread, so he know what he is finally offering you when he said.

Now what will be this "complete zip" he is offering! I hope is your desired kernel.

Max4000 In your quote

This kernel/rom lets you connect an RT8187 USB Wifi adapter to your GT-P5210 and run aircrack-ng/airmon-ng/airodump-ng through Linux on Android.

You are just looking in "This kernel/rom" at the beginning. While I am trying to tell you to look at the end "through Linux on Android."

So yes that kernel may have the "external RT8187 USB Wifi adapter driver" but in order to run "aircrack-ng/airmon-ng/airodump-ng" you need to run it through Linux....

Clearly the best approach is to use our internal wifi and some how run "aircrack-ng/airmon-ng/airodump-ng" without the need of "Linux" chrooted on Android.

@r2d23cpo Thanks

it was helpful for that Android Kitchen part

How do you create a flashable .zip out of boot.img? I am thinking of using philz to create a custom rom backup and replace the boot.img with the one i modded.

@Daniel-TAz00 Do you just edit the zimage or you even edited ur ramdisk? Eg: copy .ko modules into lib/modules/?

I did it with 7zip, open zip, replace boot.img, save zip, flash zip

I compiled my zimage, and that was pretty much it i think

Jacker31 · Mar 9, 2015

@Daniel-TAz00 Didn't expect was that easy XD just 7zip haha, gotta try it out after my dinner XD hope it works. I will post it if it works with p5220 since your post is for p5210. I have to agree with you that there is really rare to see Galaxy tab 3 10.1 series (00, 10 or 20(LTE)) development going, guess maybe there is limited advanced users on tab 3 10.1 series.

Is it possible to make a update.zip? If so how?

@Daniel-TAz00 First thanks. Nice work. But can you tell us if your "942MB" file is just the same

This kernel/rom lets you connect an RT8187 USB Wifi adapter to your GT-P5210 and run aircrack-ng/airmon-ng/airodump-ng through Linux on Android.

In particular it is VNC Linux on Android

Now I think @Jacker31 is here for the fun of learning kernel compile and finding a way to implement "aircrack-ng/airmon-ng/airodump-ng" with TAB3 10.1 own Wifi and without Linux VNC. That is what I guess from his post.

Jacker31 said:

Thanks goes to the Greatest creator @osm0sis. Last time he complains on me for saying it was another Kitchen. So NOOOO It is the best Kitchen in xda. I know all this nice applications get hidden on so many post. @moonbutt74 was the one to point me to use AIK.

I will answer down

Jacker31 said:

You see Jacker31 is trying to include the needed driver in a kernel. But that is only a step.
So, which modules Tab3 10.1 own wifi? If so you need to recall that first we need to modify our driver bcmdhd to allow promiscuous communication!

So I guess once you read this is going to be late, I was going you suggest to backup your own boot.img first! I do still you are a bit confuse it is not just ZIP!! see below

Code:

dd if=/dev/block/mmcblk0p10 of=/sdcard/mmcblk0p10.img bs=4096

Jacker31 said:

Yes, you see it is not just zip. In fact you need to make your own update.zip.

@Jacker31
1) So here is what you need to read. In this forum just search for "Edify", "updater script" and see how the script is build.
2) Please keep in mind that every device is different, in particular the partitions are in different places and in our case we are nor ARM but x86 or more technical we belong to the i686 family.
So if you unpack recovery.img an look inside the ramdiskfs you can find "/etc/recovery.fstab". By doing "cat /etc/recovery.fstab"
you will see

Code:

# mount point		fstype		device			[device2]
/config ext4 /dev/block/mmcblk0p3
/cache ext4 /dev/block/mmcblk0p6
/system ext4 /dev/block/mmcblk0p8 
/data ext4 /dev/block/mmcblk0p9 length=-16384
/recovery emmc /dev/block/mmcblk0p11
/boot emmc /dev/block/mmcblk0p10
/external_sd    vfat    /dev/block/mmcblk1p1

This tells you that "boot" is at partition "/dev/block/mmcblk0p10" and "recovery" at "/dev/block/mmcblk0p11".

So a valid script to introduce your new boot.img may read

Code:

ui_print("+++++++++++++++++++++++");
ui_print(" Galaxy Tab 3 gt-p52xx ");
ui_print("+++++++++++++++++++++++");
#
ui_print("Flashing boot.img");
ui_print("+++++++++++++++++++++");
#
#
package_extract_file("[COLOR="Blue"]boot.img[/COLOR]", "[COLOR="Blue"]/dev/block/mmcblk0p10[/COLOR]");
#
ui_print("Done");
ui_print("+++++++++++++++++++++");

Now I am attaching a update.zip skeleton. The needed part is in "update.zip\META-INF\com\google\android". There you will find "update-binary" valid for our x86 device. Observe how it is about 521KB. The ARM one is just around 125KB! Easily to distinguish. This "update-binary" is the program that will interpret the Edify commands that are store in "updater-script". So the "updater-script" holds the instructions.

In it you will find also "update.zip\META-INF\com\android". With "metadata" holds signature information when signed. And "otacert" with in fact holds the signature for ota validation. This files are only required when the update.zip is signed!! But that another process meant for distribution that I am not going to explain. In general when we test we do not sign the updtate.zip instead we disable that in the recovery menu, so that recovery accepts update.zip packages that are not signed. So I had include those for you knowledge but you can delete them if you want.

So the last file is "update.zip\boot.img". This is the file you are going to substitute and that you want to program.

And yes making the package is as simple of zipping all. Here is the important detail. When you zip the file you need to be in the same directory as the boot.img file is. So that the update.zip created do not contain an extra folder. In other words, when you double click a good update.zip you find quickly boot.img and META-INF folder. No extra folders.

Now waitttttt. That is just for your general knowledge. If you do use this info it is at your own risk. It is easily to do something wrong and break the device.

Example, Make sure you have a FULL battery before doing any firmware programing. The Charging mechanism is in boot image. If you have a bad boot image programing, then your device will not charge and if you get out of juice then you end up with a nonchargeable devices. It will feel that the device is dead, since you only way to charge will be to open the device and charge the battery separately!!!

I guess Master Jacker31 was in fact into the Linux, he just release How to run Kali Linux on Galaxy Tab 3 10.1 => http://xdaforums.com/galaxy-tab-3/general/how-to-run-kali-linux-galaxy-tab-3-10-1-t3050203
In any case I hope that my last post in update.zip is useful to him and others.

@r2d23cpo
thanks for that answer, i am akinda into the linux, but there is plentyof stuff to get confused because of this x86 device and limited support from google. You are right, thats what i am going to research next, implement aircrack into the device it self and trying to find out that i can use the usb wifi dongle without turn off the build in wifi. Maybe you can surf facebook while attacking your neighbor network *joking* *its illegal anyways*

Well, Everything work well (I meant the script, I made some minor changes), except got stuck on that samsung Galaxy Tab 3 logo screen... I am trying to figure out why... I am trying to get a stock Boot.img and compile it again, since I used boot.img from philz back up...ANNNNNNNNNNNNND great bricked my device... not the first time though.
