Rooting instructions don't work - Transformer TF300T Q&A, Help & Troubleshooting

Hi,
So I'm following the instructions to install CWM recovery on my TF300T with FW 10.6.1.27.5 (these instructions : http://forum.xda-developers.com/showthread.php?t=1668173 )
I downloaded all I needed, I unlocked the bootloader (it says this device is unlocked upon booting).
I press VOL DOWN + POWER, I get the three icons (RCK, Android, Wipe Data) - I immediately press down then up, but no matter how fast I do it, it keeps booting into Android OS and I can't get past that.
I searched for an answer but didn't find one, so I made a new post... any ideas ?
When starting with vol down + power, it says :
- Key driver not found.. Booting OS
- Android cardhU-user bootloader (1.00 e) released by "WW_epad-10.6.1.27.5-20130902" A03
- Starting Fastboot USB download protocol
Then I choose the USB icon, and it says :
- Cold-booting Linux
and it boots Android...

I don't think anybody ever told you to flash CWM with the 4.2 bootloader, which is what you have in 10.6.1.27. If you've read the whole thread you quoted above, you'd know that doing that could potentially brick your device. The only CWM version that works with 4.2 is the one included in the flatline img. used to generate the NVFlash files. Try searching for member Buster99's posts. His might help. Good luck.

Hmm... well nobody really told me not to, but ok...
Buster99's solution seems to apply to bricked devices... I didn't brick mine...
My goal was to get a 4.2.2 Android on my tablet, and since I can't seem to find any ROM with that, I guess I'll just keep it like it is...
Thanks for answering though, I didn't know I needed a downgrade...

Downgrade to pre .27.1 stock rom then root via mottochopper. Mottochopper works on JB 4.2. .27.1 and above don't work with mottochopper. FYI .15.3 stock is still Android 4.2 JB.
Check out my post on another thread for more information.

Bricked (?) ASUS Transformer Infinity TF700T

Hi there,
I need your help urgently.
I received a brand new TF700T and did make it work to support root.
I also did unlock the bootrom protection.
When I tried to install a custom ROM manager (Clockwork Mod) image from:here
The device didn't want to start any more - showing message:
The Device ist Unlocked.
Android cardhu-user bootloader <2.10 e> released by "TW_epad-9.4.5.22-20120615" A03
Checking for android ota recovery
Booting recovery kernel image
But nothing happens anymore (
I can wait for the battery to run empty in this mode.
There' no chance to boot from Micro SD.
The only thing what works at the moment is to connect the device via APX drivers.
I tried to communicate with device via NVFLASH tool
But when trying this - I get the message:
Nvflash started
Unknown Device found
Does any one have an idea where to find appropriate drivers for Nvflash?
Or the parameters to match TF700T?
Thanks in advance!
if you are able to access APX then you still have hope, first of all you need to push custom recovery like TWRP via fastboot mode and then install custom ROM. Most likelly you were to lazy to read a lot information on this forum how to install stuff properlly.
EDIT: if Tf700t has pin hole you should turn it off despite waiting for it to discharge...

I did already read a lot - for hours and nights.
But my main problem is: UNKNOWN DEVICE
What does TWRP mean? How do I get fastboot to work?
I'm even not allowed to enter recovery mode.
The device is just recognized as an APX -device...
I can't push or download any custom ROM since I can't communicate with the device in both directions...
For those who messed up really bad and can't boot but are unlocked.
EDIT: I didn't see that you are not unlocked. then you should Power on + volume down, wait, see two icons select wipe, pray to god it helped or not. And if it doesn't boot and you are not unlocked last thing to do is RMA.
You are not allowed to enter recovery because you have stock one with droid dead and red triangle I guess.This is TWRP site and all instructions are here TWRP - Team Win Recovery Project is alternative to ClockworkMod Recovery but better. to get to fast boot turn on your tab holding power on + volume down and then do nothing while it asks to pres up. if you are unlocked you will see 3 icons select usb drive icon. FASTBOOT mode. now follow instructions from TWRP site. after that youl need custom rom zip. if recovery instaled successfuly and you can get into it you'll need to put custom ro into microSD or if you can into internal storage. if you can't conect to pc via cable and start cmd if Windows or terminal if Linux or mac. type
Code:
adb shell
mount /dev/block/mmcblk1p1 /data/media
you will be able to access microSD via recovery (unless it is different than Prime tf201 you will need different command, but give it a try)

Thanks for advise - BUT
I have no choice like selecting Fastboot or USB etc. with volume buttons.
These options unfortunately do not come up anymore.
My device is definetly unlocked. It shows up "Device unlocked" when trying to boot normally.
When trying to go to recovery, with Volume - hold, the device tries to launch to recovery but hangs in status:
Device is Unlocked
Android cardhu-user bootloader (2.10 e) released by "TW_epad-9.4.5.22-20120615" A03

Booting recovery kernel.
I have NO option to go to fastboot! Only way will be APX but nvflas always tell me unknown device.
So I was looking for any other version of nvflash.
In other forum I did find hint for nvflash ICS but didn't find right version yet.
If I only could get communication via APX worked to my device, then I could send data via nvflash and APX...
I assume you can't even go to rom as it bootloops on EEE pad screen not on rom splash screen
1. Did you try Wipe option in (power + volume down, wait 5 sec.)? [it is esential in all situations of trying to recover]
2.ammm... when you enter "adb devices" in your cmd on PC doesn't it show anything (do it while your tablet is on and hangs anywhere, just make sure it is on)? list is empty? if not it shows your device with some random letters and numbers.
Try manually setting your pc. Download android SDK and all packages for Android 4.x then in Device Manager (Control panel) find your Tablet and update your driver to Android ADB interface (you can experiment, till your device is shown correctly via adb devices command).
But first of all make sure you do or did first step. it is common issue among Prime users so maybe it can help you.

I would like to exchange email-adresses to enhance communication.
You could also send email to [email protected]
I did try with button combination (power & + button) as well, but device did not wipe.
For now - I'm about to update Android SDK )
Hopefully this works to recognize my TF700T...
If you manage to unbrick please post the information back here it may be helpful to others.

How did you get your TF700 unlocked? Asus hasn't posted an unlock tool for it yet that I could find.
Asus devices have the same unlock tool

Unlock + Root was never a problem.
I managed it to unlock the device using the TF300T tool / link.
Boot loop was big problem.
I did raise RMA in the meantime. New device is on the way.
Thanks to all repliers.
I will keep off doing this again / wait until xda-experts will provide a working way to CWM TF700T.
My Transformer Infinity isn't bricked, I just can't get it to boot into recovery. (I'm unlocked and rooted, but no custom ROM.) I have tried both CWM and TWRP 2.2.0 with GooManager. The tablet just won't boot into recovery mode. I can hold the Down Volume key and Power button to have the initial boot up menu display. When I press the Up Volume button to boot into recovery mode, it just hangs like the OP talks about. I then have to hold the power button for about five or so seconds to get it to power down again. I can turn it back on and it will boot normally.
I thought maybe something was messed up because I installed busybox, or hacked the Flash Player to work in desktop mode, or tweaked the build.prop file or something. I've put the build.prop file back to default, and removed the busybox apps, but that hasn't resolved the problem. I've tried re-running the unlock tool, but it fails halfway through. I'm not sure if that's normal or not after you've run it once, or an indication of something messed up.
Any suggestions on what else to try or look at are appreciated.

UPDATE: I finally got TWRP 2.2.2.0 to work using the following option from the Instruction Page (http teamw.in/project/twrp2/105):
Download - ADB / Terminal method:
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Then reboot to complete installation.

Trying to flash the new CWM recovery, too. Mine gets stuck in the bootloader menu (where you have to choose between Wipe, fastboot mode, and cold startup). Every time I select fastboot it says "starting fastboot usb protocol" and just hangs there.

That is what it says when you are in fastboot mode, the rest of the job you do with a computer. Also we have had major issues with cwm on the Prime, I would recommend TWRP!

[Q] Please help - ASUS Transformer Infinity TF700 Brick

Hi there so, I received my ASUS Transformer Infinity yesterday and I managed to root and unlock successfully. However, after downloading ROM Manager I stupidly clicked flash CWRM it did it's thing and I thought, well, it was successful so let's try and boot into it to flash a custom ROM I had downloaded. From ROM Manager no dice, tried getting into recovery manually and it worked. However, it was clearly stock recovery. New to Android slates I clicked the volume buttons a couple times to try and see how to move the cursor... this of course wiped my device. At this point, I was pretty sure I was done for, after this completed I rebooted again and low and behold cannot get into the device on normal boot. Tried rebooting, nothing. Tried the keyboard dock, same deal. Stuck on ASUS screen and I never get the spinning wheel. Tried to get back in recovery and I get stuck at loading recovery kernel image. BRICK. The only thing I can do is get into APX recovery but as I understand there is no use for this mode yet on the TF700? Please help! My last option is to RMA to Newegg, if I do this what should I say? I feel being honest is the only way to grantee a repair. How much would this cost out of warranty?

Are you able to get into fastboot? If you press and hold power and volume down until you get the option to press volume up to boot to recovery, but don't press voume up, then you will boot into the bootloader screen, with fastboot as an option.
At this site you will find the correct twrp (choose Download - Recovery Image / Fastboot Method) and instructions to flash:
http://teamw.in/project/twrp2/105
Instructions for fastboot and adb you'll find by searching around.
Hope that helps!

I wish I could... The message I receive is as follows when I do that:
The Device is UnLocked.
Android cardhu-user bootloader <2.10 e> released by "US_epad-9.4.5.26-20120720" A03
Booting recovery kernel image
And nothing ever shows up. Just the ASUS logo.
Did you solve your problem? I'm having the same issue and tried to install custom ROMs without solving the problem
reboot the device! (power and vol down for 5 sec)
hold vol down at the ASUS screen, but don't go to recovery, just wait until you see a 3 different logos on your screen.
An Android, a Wipe and a USB Icon
go between theese logos with vol down choose USB Icon with vol up!
Now you are in Fastboot mode and with your PC you can flash another recovery image.
But by the way!

Hey, we were all new to Android at some point! That's how you learn though, by doing this sort of stuff. Nothing wrong wth trying! Just need to be careful and read alot. But, you have to start somewhere!

I never said I was new to Android. I was new to the ASUS stock tablet recovery orientation (its landscape as I found out). Hence, hit up twice, wiped data. I am by no means new in general. I did not fix the problem. I requested an RMA with Newegg and it was approved I said the issue with it was bad screen bleeding (no lie but it is normal for this tablet but bad was exaggerated) In any case! RMA approved should be getting my new unit Tuesday!
unlocked and RMA because of your own stupidity?
ok do it..

If you had my OP in its entirety, you would know that is impossible. :/ Unfortunately, after the data + cache wipe two things happened that I do not understand. 1. The device wouldn't boot (this shouldn't happen unless all partitions were formatted which the device did NOT report it did), 2. This is the really strange part, recovery no longer existed after JUST WORKING - even after my mistake with ROM manager stock recovery remained until the wipe and then I received the message mentioned in my OP (namely: Booting recovery kernel).

One more who used ROM manager recently and now I have a nice tray for serving beers :crying:
I'm having the same issue with APX available by powering on the transformer holding volume+up but with no nvflash backup.
I don't understand why people keep using ROM manager to install recovery, this is a death wish to your device. If they read all the "How to" posts, none of them instructed to use rom manager to install recovery, so I don't know where they got this idea from???? beat me!!!
GRIM1337, you need RMA to send out for repair. Sorry but there's no hope to recovery this.

Updated to JB (from rooted ICS), then tried to unlock and flash recovery: Bootloader is still locked, recovery and system partitions are simply gone!
All I can access is fastboot now, but as bootloader is locked, I cannot flash any custom image/blob or whatsoever.
Can someone generous post their stock recovery or help me flash the JB update ZIP again?
I extracted the blob, but I'm not sure how to flash it? I suppose it contains all the partitions I would need to flash! But how to flash them?
I tried this:
fastboot -i 0x0b05 flash staging blob

Well that one's hard: With ICS bootloader, there was like no fastboot mode!!! On the bootloader menu I could only confirm recovery or cancel to boot as usual!!! WTF? But then once with JB bootloader, the menu allowed me to select a different option: a new one had appeared showing a USB logo too! Can't tell if I simply missed the option or proper steps in ICS bootloader though.

ICS bootloader had the fastboot option disabled if the device's bootloader was still locked and the USB icon wasn't showing at all.
With the JB bootloader Asus made the USB icon available even if the device was locked so you can access fastboot mode but you can't flash anything (yes,it doesn't make sense, but this is Asus).
Anyway, if you are able to boot in recovery you should be able to restore you device easily,just follow my guide from the general forum.
Re: Help needed i will try
OK WHAT YOU HAVE DONE IS WIPED THE OS FROM THE UNIT...AND LEFT THE BOOTLOADER FILES...SO THERE ISNT
ANYTHING TO BOOT TO AT THE MOMENT... I DID THIS LAST WEEK... IT WAS A BIT SCARY AND FRUSTRATING UNTIL
I FIGURED OUT HOW TO FIX IT.. ITS NOT HARD. ILL PUT DOWN HERE WHAT I DID...
1. DOWNLOAD THE GOOGLE NEXUS 7 TOOL KIT... ( this is a very good rescue tool )
2. RUN IT... INSTALL THE DRIVERS... REBOOT IT ALL AND START THE TOOL KIT AGIAN WITH YOUR TRANSFORMER
CONNECTED TO USB...
3. YOU SHOULD SEE THE SERIAL NUMBER OF YOUR TABLET AT THE TOP OF THE PAGE IN THE TOOLKIT...
IF SO..YOUR ALMOST DONE !
4. THERE ARE MANY CHOICES..SOME WORK SOME DONT ON THE TRANSFORMER...
5. I CHOOSE THE ROOT OPTION...
6. NOW..WHEN IT GETS TO THE PART WHERE IT SAYS ARE U IN FASTBOOT MODE.. SAY NO !!! THAT WILL ACTUALLY
PUT IT IN FASTBOOT AND THEN PROCEED AS DIRECTED ON THE SCREEN TO ROOT...
THATS WHAT I DID...CAUSE I NEEDED ROOT AND I HAD A STUCK BOOT LOOP JUST LIKE YOU.....
BASICALLY YOU NEED TO ROOT IT AGIAN AN THEN REBOOT AND TRY TO GET INTO CWM..OR HAVE IT REINSTALL CWM...TO FLASH A ROM...THAT WORKS..

[Q] HELP! I think i bricked my TF700 while installing Jelly bean.

Hi All,
i have unlocked bootloader, Rooted ICS
now i installed the latest JB update via the SD card method (renaming it to E201_768_SDUPDATE).
did the power+vol down method. intstalled it and reboot.
now all i get is this message coming up.
"The Device is UnLocked.
Android cardhu-user bootloader <2.10 e> released by "US_epad-9.4.5.26-20120720" A03
Booting recovery kernel image"
and it gets stuck there at the ASUS screen.
i have tried to install the APX driver from universal driver 0.7 TF700, and all i get is unknown device in win7 device manager.
hence i cant get into NVflash or Fastboot.
is there anything else that i can do to unbrick this tablet.
are there any other drivers that i need to install in win7 x64 or it to recognize that it is an asus tablet.??
Looks like the JB update didn't write everything properly - you still have the old bootloader. You should really have created backups for nvflash before trying to upgrade to JB.
But it's still not too late. Can you switch yout device to fastboot mode? If yes, then it's just a matter of getting your PC configuration right.
Then the next thing I would do: re-flash some custom recovery via fastboot, make sure it works and you have adb root access, check if /sdcard is ok, then install the AndroidRoot bootloader to create your blobs for nvflash, reboot into recovery, pull the blobs to your PC via adb, and only then try to upgrade to JB again.

Hi, no unfortunately i cant access fastboot, i have tried using the TWRP method of and all i get it a message saying waiting for device. when i try to push the TWRP.blob file.
i think my problem is that the usb device drivers are not working hence win7 x64 cant recognize the tablet when it is turned off (APX mode i believe)

Let's check it step by step:
- On the device, can you still activate the fastboot mode (USB icon)?
- On your PC, you should see a USB device with vendor ID 0b05 and product ID 4daf. Should be visible somewhere in Device Manager under Windows, maybe someone else can give you details (under Linux everything is much simpler with lsusb).
- On the PC, "fastboot devices" should give you more than no output at all (some question marks, AFAIR).

And if you hold down Volume-down while powering on, it's the same? In that case, 3 icons should appear before it tries to start the recovery kernel.

You're done. You need to send out for repair. Sorry, but I haven't see any one here able to recover the device with the above message.

hmm bummer.. no other way to force install a device driver to detect the tablet on my win7 pc.? all i need is a glimmer of hope that i can still talk to the tablet at the lowest level interface. ie APX mode.

The driver on your PC is not the problem. For using nvflash in APX mode you'd need the Secure Boot Key, which is unique for each device and which Asus does not give us, or the blob for the wheelie tool that can be created with the AndroidBoot hacked bootloader, which is also unique for each device. But for creating this blob, you need working fastboot access.

Ploblem with bootloader

Hi guys, i have a question:
wiht FW 4.2.1 if i reboot on bootloader screen, and in the top left of the screen, you will see a sign that says: Key drive not found .... why?
could you help me?

Same here & a few other people I have asked also have this.
Not sure but I think everyone on 4.2.1 bootloader now has this "Key driver not found...Booting os..." message in the top left corner of bootloader.
I don't know what it means though.
Not only do I have this, but no computer I have will fastboot anything to the tablet it just sits there after I do the flash command to flash twrp for as long as I let it sit and never completes.. Also by trying to boot into recovery I get the fallen down android with the red !.
It will boot into Android just fine, I just now have no recovery. The device is unlocked because it tells me it is unlocked when I boot it, but I can't flashboot anything and it has that key driver not found thing on it also. Not sure why my recovery isn't there since the only thing I have ever done to it was unlock using the V8 tool since I am on 4.2.1 and then try to flash the right 2.4.4.0 patched version of TWRP. If it isn't seeing my device I can't see how it would have wiped my recovery.
Seen several people with my issue and have even asked a question but so far no one has responded.
Edit: I still have that error on the bootloader but I finally got TWRP to flash after going to a 3rd computer and using a USB 3.0 port. Don't know the significance of the 3.0 port but it worked so I am not asking questions.

Adndroid with a red ! means you have the stock recovery. Not sure why you can't use fastboot. I'd check all your drivers on your PC first as that is the most like cause. Start by uninstalling and reinstalling the Android SDK.

I got it to work. Weirdly It took 3 different computers before I got fastboot to recognize the tablet and allow me to flash the recovery. I was worried, but if you say the red ! means I still had a recovery then obviously it was just a communication issue with my device. The problem is now that only one of my three computers likes to communicate via fastboot and all three had the appropriate USB drivers installed. I am going to have to blame it on Windows most likely overriding and installing a wrong driver possibly.
I got TWRP and root. Debating on which ROM to flash now CROMi or Energy.
I still get that key driver missing at the top in the bootloader menu but obviously it isn't hurting anything and fastboot still works.

[Q] [nvflash problem][TF700T] stuck at boot screen after step 1

I've been trying to get nvflash access though this guide [androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/] but after doing "Step 1: Flash AndroidRoot BL" and rebooting the device it gets stuck at the ASUS logo screen (without the spinning wheel).
It's an unlocked TF700T successfully downgraded from JB to Firmware .30.
Did anyone else encounter this problem and has a solution?
I'm a little afraid to do the whole flashing proceedure through fastboot again without knowing if that's a good idea.
Why did you downgrade to an ICS firmware???
Which guide did you follow? Step 1 should have been to flash the recovery flatline_device image. And then you use it to flash the modded bootloader (which is JB 10.6.14.4 BL btw).
Can you still boot into fastboot and the recovery?
Here are the official instructions for nvflash: https://www.androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/

Thanks for the quick reply.
I downgraded because a guide told me (here on XDA) that to root my device i'd have to downgrade to ICS because of some exploit, which has been apperantly closed in JB, for 'motochopper'. Well that's what I remember.
My Firefox and PC crashed and I lost my tabs so I couldn't find that guide right now...
For nvflash I read exacly that guide you refered to.
I am still able to get to the flashed flatline recovery and since the usb icon (fastboot) isn't there where the 3 icons are showing I assume it's running by default (?).

Yes you are on fastboot by default now.
So, what could you suggest?
Should I (be able to) upgrade back to JB, to 10.6.14.4?
There's no need for root in any of this. Downgrading was what messed you up I believe.
I think you are ok. That you have only 3 icons indicates that the bootloader flash went fine (ICS BLs have 4). Confirm this by reading the tiny script in the upper left on the bootloader menu screen.
My guess is that this bootloader doesn't do well with ICS firmware. But the BL flash happens before Android gets booted. Did you see a blue progress bar during reboot? That would have been the bootloader installing. So it flashed ok, but then got stuck on booting the rom.
So you should be ok to proceed.
The rest of the process is done in recovery and APX mode. Shouldn't matter what ROM you have installed.
Once you generated your backups, you have to flash a bootloader and recovery for whatever rom you want to run.
I would recommend you flash the bootloader/TWRP package from the CROMi-X thread. That BL may boot the ICS rom you have currently installed, but even if it get's stuck on booting the rom - don't worry.
Same process: bootloader and recovery get installed before Android boots.
Just boot back into TWRP and flash CROMi-X. Even if you eventually want to run something else - this would give you a stable base.

jhh
yeah after flashing the AndroidRoot recovery image (flatline_tf700.img) thorugh fastboot I saw the blue bar telling me it flashed successfully. I could even reboot .
But then after flashing the AndroidRoot custom bootloader I wasn't able to reboot anymore. There was no blue bar during reboot.
The upper left corner says:
Code:
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.1.14.4-20130329" A03
Starting Fastboot USB download protocol
Hm... I was planning on having CROMBi-kk but the guide says it needs 'ASUS STOCK JB 4.2.1 BOOTLOADER VERSION 10.6.1.14.x'... so that looks like that won't happen for me unless I manage to flash it back to the stock bootloader somehow. :/
So do I understand this correctly:
With the current Firmware .30 still installed I should take the latest CROMi-X package. Flash the recovery and the bootloader over the current one and then flash the CROMi-X rom?
What about nvflash then? Will I be able to generate the blob files with TWRP? I'm asking because AndroidBoot recovery looks like a modded CW-recovery I think and it has the options 'advances > wheelie > ...' , where you do the whole "nvflash stuff".

Yes, I was able to create the wheelie blobs if that's what you mean, but I wasn't able to adb pull those. Don't know what I'm doing wrong there.
I'm not sure how to continue from here on after creating the blobs.

I wasn't able to adb pull them either, but they are there. Serach your entire SD card for blob.bin and/or bricksafe.img and you'll find them. Can't remember where wheelie hid them.....
You have a very specialized recovery and bootloader right now which you have to change to run a rom.
To get to the latest bootloader you can either flash the bootloader/TWRP package from the CROMi-X thread or flash the latest Asus firmware file.
Then reboot.
If you want to go for CROMBi-KK you have to install TWRP 2.7
Reboot
Do a factory wipe in TWRP
Then flash CROMBi-KK
Ok got it all sorted out with alot of help.
There was alot of fastboot erasing and so on involved
and flashing of the latest Asus firmware.
Then we got the whole nvflash procedure up and running, generated and saved the blob files,
flashed TWRP and CROMBi-kk and voila.
My TF700T is up and running.
thnx for all the help

It's faster than stock asus rom that's for sure.
I know it's not quite finished but I've noticed some bugs like:
- when using chromecast the right quicksettings panel glitches quite alot (I'm using trebuchet)
- I've noticed that occassionally the power button (on device and keyboard) doesn't work to turn off the tablet or set it to sleep. only by closing the 'netbook/tablet-keyboard-hybrid-thing' it goes to sleep. after soft-resetting it the problem was gone. I think it only happened when I accessed the glitchy quicksettings panel while using chromecast.
Other than some of the still missing features it's running quite good
I don't regret flashing this custom rom over the slow and old stock one.
