Here I am again...
This time I have written a shell script (linux only) and made a live-cd (for all windows/linux users) to automatically root the stock firmware on the TF101. Every stock firmware.
Today in Europe Asus rolled out the 3.2 upgrade. If you are on stock and you have alredy upgraded then download attached tar file and do as follows:
NOTE: Unfortunately, this script won't work with the latest revision of TF101 (3G version, B80 and some B70)
NOTE2: As someone pointed out (thank you Pieter) you need to be root on your linux box in order to make it work.
Code:
tar -xvf universal.tar
cd universal
./universal.sh
In Ubuntu the last command would be:
Code:
sudo ./universal.sh
Follow the instructions and you're done.
If you have a stock US/DE/TW/JP/TB firmware you can do the same.
If you are running an older version of Honeycomb the process is the same.
When ASUS will pull out another upgrade... same commands as above.
So this probably is the closest thing to one-click-root for the Transformer.
This won't install custom rom/CWM/strange other things (V2 version added the support for CWM); it's only root.
I've tested this morning after the 3.2 upgrade and it worked like a charm.
However this is in testing stage so, as always, if you brick/ruin/burn/crash something don't blame on me.
This package includes the Bootunpack tool, courtesy of Rayman84
LIVE CD INSTRUCTIONS
It's based on slitaz (http://www.slitaz.org/).
Burn the image into a cd or if you want it on a thumb usb drive follow this (http://doc.slitaz.org/en:guides:liveusb).
Put the cd/usb in your pc and reboot.
Follow the indication on screen (for setting locale and keymap).
When the desktop shows up, double click on "Universal Root for ASUS TF101".
Again follow the indication and you'll be ok.
For a guide on how to boot from cd/usb try this: http://www.passwordunlocker.com/knowledge/change-bios-settings.html
or search with google.
The option to install a stock boot/recovery (added on V3) is working even if not fully tested.
The program has correctly rebuilt a stock recovery on my WW version.
From version V4 root checker correctly says that the rom is not rooted after you do an unroot.
If you like the work i did take a look at that funny button under my name with the "donate to me" caption
Seriously, I appreciate even only a "Thanks".
FAQ
[Q] I'm running on Windows, how can I burn the live-cd?
[A] Try with cdburnerxp (it's the easiest way).
You can download one installer frome here:
http://cdburnerxp.se/en/download
or the portable package if you don't want to install other software:
http://download.cdburnerxp.se/portable/CDBurnerXP-4.3.8.2568.zip
Start the program (for the portable version the file is cdbxpp.exe) and click on "Burn iso image". Then select the .iso file you have downloaded and click "burn disk". All Done.
[Q] How can I reboot in APX/recovery mode?
[A] Do as follows:
VOL UP + POWER BUTTON for ~5sec = boot in APX mode. The screen will stay black as if it is turned off. This mode is used only when you use nvflash to flash boot/recovery/data partition (this is the first step in my script).
VOL DOWN + POWER BUTTON ~5sec = will appear a screen where it says to press vol down again to wipe all data (obviously you don't want to do it now), or press up to enter RCK (recovery mode). If you installed CWM you will see the main menu navigable with vol up / vol down / power button.
If you have the stock recovery you will see a green android with a esclamation mark on a yellow triangle.
[Q] Help! I can't reboot in recovery mode!
[A] I think the main problem here is that it is a bit tricky to get into CWM recovery, once you see the small text come up don't try to read anything, just hit volume up.
Hold volume down plus power until the text in upper left shows,if you let go too early it just boots up and you never see the text. If you wait too long you don't get the option to boot into recovery. Hope that helps..
Thx to ckuke4 for this answer http://forum.xda-developers.com/showpost.php?p=16306342&postcount=60
[Q] The live-cd gave me this error: "connection failed NvError 0x8" what is it?
[A] This means that either you are not in APX mode (read above), or that you have one of the latest revision of the tf101 (B7O) which have an unknown (for now) sbk.
For what i know, there's no knew method for rooting your device.
Maybe someone will find a way, but for now you have to be patient.
[Q] I'm running your scripts from my linux box, but it keep me saying "Permission Denied". Why?
[A] You need the root privileges on your local machine.
If you are running Ubuntu:
Code:
sudo ./universal.sh
[I](it will asks for your password)[/I]
If you are running another linux distro:
Code:
su
[I](it will asks for your password)[/I]
./universal.sh
[Q] I have rooted my tablet with this method, but I can't find the superuser app and Titanium Backup says that I am not rooted.
[A] The root script will asks you to reboot your tablet, make sure that usb debugging is turned on and then press any key.
You have to wait until you see a little bee on the bottom right of your tablet's screen, near the clock. Then press any key.
[Q] I've installed CWM but every time i try to do a backup, it says it can't find sdcard. But my microsd card work fine with root explorer!
[A] Don't get me wrong but, are you sure?
In root explorer you see a sdcard folder but it's not your microsd, it's the internal memory (it's weird, i know). In root explorer the microsd card is mounted under the "/removable/microsd" folder. You should also see a little sd card icon in the bottom right, near the clock.
Also you need to make sure the card is formatted correctly. Try reformat it with this: https://www.sdcard.org/consumers/formatter_3/
Thanks to skeeterpro for the link (http://forum.xda-developers.com/showpost.php?p=16385872&postcount=6)
[Q] The live cd stops at the command prompt, I can't see the desktop.
[A]The live cd doesn't include every driver for every video card, mouse, keyboard, etc.. (keep in mind that the original slitaz livecd is only 30MB).
You can do all the process in the text console, it's not much more difficult.
If it asks for a login insert "tux" (without quotes).
At the command line enter the following:
Code:
cd
cd universal
./universal.sh
Then the magic will start. The unroot script is called ./unroot.sh
CHANGELOG:
V4:
- Corrected some text
- Added a link on the Desktop to this thread
- Added stock ramdisk for all SKU (though JP, CN and DE are not the latest versions) (thanks to kovla for the latest TB recovery)
- Added a script on the Desktop to increase the font size on the fly for those who are using a very high dpi monitor/tv.
- Changed compression algoritm. Now the iso is ~10MB smaller.
- Maybe I have found the way to make everyone read the faq...
V3:
- [BETA] added a second script to come back to stock.
V2:
- added the option to install CWM (thanks Roach!)
- more error check
V1:
First version
=====> DOWNLOAD LIVE-CD V4 - (Mirror)<=====
DOWNLOAD LIVE-CD V3 (previous version)
DOWNLOAD LIVE-CD V2
As always, keep your eyes open and
Have Fun!

In linux there's no need for drivers to work with tf101.
Windows seems to be problematic with driver (for someone seems to be way too difficult install the right ones).
As i stated above, adding this to a live linux cd will be the final one-click-root (put a live cd/usb-memory on your computer, reboot, follow the easy instructions and you're rooted).
Sincerely I don't know how to modify a livecd to add these scripts and programs.
If anyone wants to try, he is welcome.
Anyway I don't plan to do a windows port of this.
Disappointed! No windows support!
Will probably be trying this method from my PCLOS partition, if I can hold off the OTA update which has just begun pestering me.
Got to find out whether the modded adhoc wpa_supplicant works with 3.2 first, thanks for the effort HF
Excellent, glad to avoid having to dig out my old Windows box to root the TF Would advise people to drop it, new Mint/Ubuntu is much nicer visually than Win7 and my startup times are fantastic, not to mention the slick media support.
Does you script give also install CWM?
Will give this a go later and see how it works.

I was thinking on it, but perhaps it's better no.
Installing cwm means no more ota, since the update relies on the stock recovery.
This script was meant to leave all as stock as possible.
For all the windows folks:
I have added to the first post a live-cd with all the necessary tools.
Just run it and you'll be fine. (anyway, you are always in time to switch to linux)
Hallo and thanks!!!
what about mac's Users?
Can you explain a bit about what it does? So we can all learn.
Thank you,
Hi !
Will it work under wmware or virtual pc ?
Sorry if this is a dumb questions, but would this work in Terminal in OS X?

So you wanna learn? Good!
First i learned how to root the stock firmware from here: http://forum.xda-developers.com/showthread.php?t=1125714 .
Essentially the steps are:
1 - download a modified boot image into the tablet
2 - install the su and superuser packages.
My scripts do these 2 steps. I wrote a small howto that explains how to modify a boot image (http://forum.xda-developers.com/showthread.php?t=1193737)

I really would like to have an answer to these questions...
The Mac should have a layer of compatibility with linux (can't tell you more), but i really don't know the mac world.
*Maybe* the live cd will work under virtual machine; there should be some options to enable the usb feature. In Virtual Box there's an option to enable the usb controller and an option to filter what device will be accessible to the guest os; don't know vmware and virtual pc.
I don't know if an Intel based Macintosh is able to boot from a x86 live-cd, you could try.
I'm sorry i can't help you much more.

Oops- no- there is no Nvflash for Mac. Sorry.
Created a live usb, booted via windows, and voila i am looking at a linux desktop, which i have not seen for a long time. Started going to its paces to root my tf, but did not push thru to the end, in as much as my tf is already rooted beforehand. But i can sense that barring any unforeseen miscues by the |op|, this almost one-click rooting procedure should produce its desired result. Highly recommended; good job |op|.
Looks like this calls for an "unrooting" routine to complement the rooting process. How about it?
Nice script! I just completed one of my own for unrooting the TF
One thing: why not just use adb reboot recovery instead of telling them how to do it manually?

I have already tried this, but seems it doesn't work.
if i write "adb reboot recovery" or "adb reboot bootloader" my tablet reboot in normal mode.
It's more reliable do it manually.

For now if you are running on windows, you can use one of these methods:
http://forum.xda-developers.com/showthread.php?t=1125714
http://forum.xda-developers.com/showthread.php?t=1185104
you are already rooted, so just need the cwm.
Since i had many requests on adding cwm, i am going to update the scripts and live-cd for adding this feature.
I'll keep you updated.
I've been looking around for some good tutorials, but in my opinion, almost everything was pretty difficult to understand for me.
But finally I found out how things are working (except of wifi, can You help me?
http://forum.xda-developers.com/showthread.php?t=1295718)
So I want to share my knowledge with You all and try to make it easy to understand.
1. The ony way in the moment to install Ubuntu on Your Transformer is over a Ubuntu or other Linux PC. (I easily installed Ubuntu virtually in VMware Workstation)
2. Get the required files on Your Linux machine:
http://forum.xda-developers.com/showthread.php?t=1191141
On this link, in the second post is written flash kit for linux:
klick on "here" to download the flash kit.
3. Extract the flash kit into a folder (e.g. Desktop)
4. Now download the Ubuntu root files. They are located here:
http://rootzwiki.com/showthread.php?1072-ubuntu-on-the-transformer
You have to scroll a bit down then You see
"ubuntu-rootfs:
is available here md5sum(95eda389e64461533c51fd1e4e237a30)"
Again, click on "here" to download the rootfiles. (It'll take a while, since the file is 950mb)
4. Once this is done, extract the rootfiles into linux-flash-kit/images. (This folder is the one You have extracted in 3.
5. When You want to Dual-Boot Your device with Andoid AND Ubuntu, read on, otherwise go to point 6.
You have to download a nvflashable rom like for example "PRIME!"
http://forum.xda-developers.com/showthread.php?t=1251044
There You download the NVflash version and extract the image files in it, to linux-flash-kit/images, like You have done it with the ubuntu image file.
6. Now You have to choose.
If You want only linux: remember flash-purelinux.sh
If You want linux and Android Dual-Booting with Android as default OS:
flash-linux-android.sh
If You want linux and Android Dual-Booting with Linux as default OS:
flash-linux.sh
If You want to restore back to android: flash-android.sh
If You want to get to factory state: restore-default.sh
Now You have to install the APX drivers. How to do this, You can read in other threads. Basically download the NVflash file from this thread, in it, You'll find the drivers: http://forum.xda-developers.com/showthread.php?t=1123429
So connect Your tablet to Your PC, turn it off, and turn it on while holding down the Power Button and the Volume+ button.
What You'll see is nothing. Now Your device is in APX mode.
In Your Linux Computer, open up the console and go to the linux-flash-kit directory (In my case it is on the Desktop)
so I do:
cd Desktop\linux-flash-kit
So now You are in Your linux-flash-kit directory. From here You have to type:
sudo sh flash-linux-android.sh
OR You type this in what You have remembered in Point 6.
e.g.
sudo sh flash-purelinux.sh
or
sudo sh flash-linux.sh
This will take a while because the files are transfered to Your device.
7.
When it's done, Your device will start.
Turn it off, and start into Your Ubuntu.
When Ubuntu is Your main system, You start it up normally by pressing the power button.
When Android is Your main system and You are Dual-Booting it, hold down the power button and the Volume down key until the device says that Your have to press the Volume-up key. Do this and You will see a Linux code with two penguins on the top running down Your screen. That's just good like it is.
Finally You should see the Ubuntu Setup with the language selection.
Now You can go on, and now You can set up Your Ubuntu PC!
FYI:
When You have not got a keyboard-dock, Connect Your tablet with Your pc and enter the adb shell
When You don't know how to enter it:
open up Your console, get into the directory of the android-sdk and into the platform-tools.
Then You type:
adb shell
Now You should be in the ADB shell
Now You can type:
DISPLAY=:0 onboard
Then a virtual keyboard should appear on Your tablet and You're ready to go!
Just to create a vocal point, This requires root doesn't it?
Also, is the wifi and stuff working? What's not working?

Nice guide. There is one correction: it took me a while to find this but there is a windows-flash kit that I've used to install ubuntu on the transformer from Windows 7.

I don't think so, because everything is flashed via nvflash. This way, You can flash a rom without having it rooted, too.
But I'm not quite sure..

Thank for this, I am itching to try this... Is there any "easy" way to get back to stock honeycomb after i try this ?
(sorry for this stupid question, I do no know much about these things)
In my opinion it's very easy.
On the one hand, run the command
Flash-android.sh
Or
Restore-default.sh
Or your use nvflash to wipe the device and get a normal rom on it.

Hello yesterday i've try to put linux and android on transformer, all work's great but after 5 minut nvidia apx was disconnected because battery load 0%; i work on vmware machine; after I've charged my dock e tablet and run again the script but that's is the result
sudo sh '/media/Nuovo volume/linux-flash-kit/flash-linux-android.sh'
/media/Nuovo volume/linux-flash-kit/flash-linux-android.sh: 2: /ubuntu/abootimg-i386: not found
/media/Nuovo volume/linux-flash-kit/flash-linux-android.sh: 3: /nvflash: not found
rm: impossibile rimuovere "linux.img": File o directory non esistente
why?
I've already tryed to restore with nvflash all partition and download all in new virtual hdd but not work.
hi! my apologies but i searched and read alot of post already on how to solve this.
i flashed Roach latest CMW how ever being so stupid i forgot to put a ROM on internal memory. did full wipe already and i have no ROM to flash as it reads internal memory only.
ive read alot of post regarding the concern, i want to try to push a ROM on internal drive using ADB but when i run "adb devices" nothing is found.
any suggestions or any links to posts that i might get help or tutorial. im not an expert on using ADB so keep instructions simple, im a noob i admit it but i just need help. thanks!
read through posts "[Troubleshooting/Solved] ClockworkMod recovery 5.5.0.4 from Koush" "Used roach's new CWM recovery, now can't intall rom" "
im on recovery and when i run adb devices it just blank. any walk through is much appreciated!
Do yo have USB debugging on?
I dont know because i was about to flash a new rom so i did a full wipe already
Did you ever get ADB working before all this? USB debugging usually have to be turn on by the user. In Settings>Developer options.
i havent with my tablet but with my htc desire hd i used adb. and when ever i flash a ROM on my tf i usually turn on usb debugging always. right now in on recovery roach r2. my ROM is on my external memory. also tried to do a nvflash how ever whenever i run the download.bat cmd opens then closes 3 secs maybe
i also got a new sdk from this forum " [GUIDE] Getting ADB Setup; An Idiots' proof guide on getting ADB working for Rooting!" as ave said above when i type "adb devices" its just blank and does not list any device.
I had exactly the same problem - I'm not sure about tablet version that I own, but I've flashed Wipe Lite and new Recovery. I also have HTC phone that I've been using on the same PC .
I've spent an hour trying to get my TF back on feet and I managed it.
I would recommend uninstalling all HTC and ASUS software and drivers, rebooting PC and installing just ASUS PC Suite. It worked in my case - suddenly Device ID showed up for a few seconds before ADB reported "no device" again.
So I've pushed Rogue XM Recovery to data/media:
adb push roguexm data/media
Of course use name of zip file instead "roguexm" in command above.
After that zip file showed up on sdcard and I could flash it - it doesn't support AROMA but it works quite fine otherwise.
Hope it'll work in your case. Good luck!
Hope it will help
I once were in your case, did full wipe and forgot to put a Rom in internal memory. But in my case I just rebooted the transformer and all of a supprise, my tablet reverted to the stock Rom! I dont know how this happend but may be Asus did something to keep stock Rom persistent whatever you have flashed roms or CWMs.
So i hope this also happened in your case, just give it a try. Good luck!
If he did "Full Wipe - factory reset" then he should be able to boot HC/ICS and from that copy files onto internal /sdcard.
But if he used Android Revolution Super Wipe script either Lite or Full then he has nothing to boot into, no system at all - I've done that Only thing that left was recovery without external sdcard support, so I had nothing to install...
ASUS and HTC drivers have some issues and make everything harder than it should be, that's why I recommend to uninstall all HTC and ASUS software, rebooting PC and installing ASUS PC Suite only, to have "clean" drivers on PC.
I've tried different drivers and none of them worked, until I've done that.
Ok, I'll try to write it simple, I'm not sure if I can post links so just in case I'll give thread names. If it will be too simple don't get mad - ok?
1. Uninstall ASUS and HTC software, reinstall ASUS software like mentioned above.
2. Create folder on your C: drive called CWM
3. Go to post "Eee Pad Transformer Android Development\[Recovery] Rogue XM Recovery v1.3.0 (CWM-based Recovery v5.0.2.7" thread - http://forum.xda-developers.com/showthread.php?t=1446019
and "save as..." cwm_recovery-5027_rogue_rburrow-tf101-r1.zip to C:\CWM
4. Highlight/select command below:
adb push cwm_recovery-5027_rogue_rburrow-tf101-r1.zip data/media
then right click on it and select "copy" - it will save you typing it later.
5. Boot Recovery on your Transformer and connect it to PC, let system install device drivers
6. Click START, "Run...", type: cmd
7. It should show you path to your profile folder - C:\Users\yourname>
8. Type: cd /CWM
it will change folder to C:\CWM>
9. type: adb devices
(it should give you your device ID, if it still will give "no device id" then there I can't help you - I'm sorry)
10. right click on black background and select "paste" (you'll see command that you've copied from number 4), then press enter
11. It should copy recovery onto your internal sdcard - you will be able to select it from tablet
12. type adb kill-server and disconnect tablet, install new recovery and from that one you will be able to select external or internal sdcard
Notes:
I don't know why but I was able to send only small file from CWM-adb connection, it kept disconnecting quite quickly that is why I recommend sending Rogue XM Recovery instead of whole new ROM.
Other thing - it may depend on what windows system you have - I'm on Win 7 x64 (don't remember how it worked on other versions) and I can paste onto cmd (black) window without problems from right click menu. If you won't be able to paste there or you'll get some rubbish, try to right click on top bar and select "Edit" and then "Paste".
Ok, that's all. Hope it will work.
thanks for all inputs. i did a full wipe but not as scripts. i wiped manually. i did try to reboot but stuck as eepad screen. will try to re-install asus drivers and uninstall htc ones. hopefully i get it done today. i will update later...
still no luck. device not found. im going to try to install new sdk... i hope it works. ive already removed htc sync and drivers. also re-installed asus sync and updated drivers. on device manager detects on other devices transformer but drivers are not installed.

Could you tell me how to do that? Because I have the exact same problem.
I'm looking for the APX drivers for TF300T. Naked Drivers .72 says it provides for
TF101 and TF201 (doesn't have TF300 or TF700 listed). I'm also concerned about
driver clash with my existing HTC devices (GB, HC, ICS & JB) which all run well
with ADB and fastboot (all S-Off). I'm hoping the ASUS suite installed the basic
drivers (UMS/MTP & ADB).
My current intent is to stay with ICS to keep UMS and flash support.
To prepare for nvFLASH, I've downloaded the 2 zip files and extracted
them (the tools setup and nvflash and its dlls). Once I have the drivers,
I plan to use root tool to root ICS, then unlock and run nvflash to get
the backups. Are there any ICS updates I should take before rooting?
Is there an easy way to suppress the update to JB notifications?
Thanks
ALARM: the device could be bricked if something will go wrong.
Actually should work for 10' and 13' as well
Introduction
The Yoga Tab 2 devices are built on the Intel Baytrail SOC, which makes them not very different from cheap Intel Atom laptops and idea to make them run something more serious than Android is too tempting to resist. Even more interesting, the Windows version of the devices do exist, so running of the full desktop OS is definitely possible.
Beginning
The easiest method to boot Linux on the Yoga is to unlock bootloader and replace standard EFI loader with GRUB. To do it, use the set of files, available here.. Unzip the file, put the tablet into fastboot mode, connect to PC and use script hack.cmd to flash the ESP with GRUB. Now, the system will be booting the GRUB, which will normally boot Android (if no buttons is pressed). The volume buttons are configured as hotkeys in grub.cfg, so it is possible to load arbitrary system, supported by GRUB.
To modify the grub.cfg from Android, mount the ESP partition:
Code:
su
mkdir /esp
busybox mount /dev/block/by-name/ESP /esp
vi /esp/boot/grub.cfg
Kernel
The device is able to boot mainline Linux kernel in the described way, but due to erroneous ACPI tables majority of hardware won't work. I did my best to repair the tables to make system usable. Still, not everything is working, mainly screen brightness control and sound. The kernel development info is available at https://github.com/Trel725/yoga2linux
System
I've chosen Manjaro Linux as a distro to work with because of my own taste. It shouldn't be a problem to run any other distro with modified kernel, but I provide rootfs only for Manjaro.
How to get it working
1. Flash the modified ESP as desribed above.
2. Download the archive, create folder /factory/manjaro (folder /factory should be already present in the tablet) and unzip archive to that folder. It is necessary because GRUB can't access the external SD, so kernel need to be loaded from internal memory and then find SD card. /factory is just a partition, used for storing tablet configuration, and as it is usually empty for 90-99 % it is convenient to use it to store the kernel and initramfs.
3. Find a good SD card, format it to the ext3 or ext4 FS and unzip RootFS to the SD card. Insert card to the tablet.
4. Reboot and press Volume+ to boot Linux.
Some ideas
1. After tablet has booted Linux and USB is initialized, it keep it's state on reboot. This means that following trick is possible:
boot linux -> reboot -> get to GRUB (by pressing Volume-) -> USB keyboard should work as it was initialized -> go to the GRUB command line (press c) -> type exit, press enter -> should get to BIOS with working keyboard -> if USB flash disk was inserted before entering the BIOS (usb hub is needed as device has only one port) it is possible to boot from it.
2. TODO
Hello, do you have any Linux tutorials installed here?

Thanks for this, @Trel725.
No problem with 5.2 kernel? isn't it too new for such an old device?
Also -- maybe some stuff from here is relevant? e.g., WM5102.

Which tutorials do you mean? Linux usage in general?

Linux is very good in backward compatibility, even support for 80386 (released in 1985) was discontinued only in kernel 3.8. Moreover, I am particularly interested in mainline kernel without need to support ancient code (like for majority of android devices).

Thank you for the suggestion. I didn't try the patch for WM5102 from github, hopefully it will work for mainline kernel. I will try to find some time for it in the future.
sorry，my bad
i mean install linux for yoga tablet2 ' tutorials.
The tutorials in the forums all failed.
If you are free, can you teach me how to install it?
Thanks very much.
Unfortunately I don't have time for complete guidance, but if you have any questions I will readily answer them. The more details you provide the easier to help you.
alright, Thank you all the same.
But if you have time, please help.
My E-mail is [email protected]
Just a simple tutorial.
thank you
I can get Manjaro to boot but it can't load LightDM. I'm on 1050L.
I cant get this to work... All i get is a shell command line. no dual boot. Doesnt default into Android if nothing is imputed.
I tried connecting a keyboard. And cant type anything in.
I feel some steps have been skipped.
Tried this and now can't do anything but sit in empty shell. Can't type, volume buttons do nothing
