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!

An unusual TF300T Brick

Yeah, I'm having problems with my TF300T, too. I had CWM installed, but when I tried to flash a new ROM, I bricked it. No problem, I had figured it out before. But when I was in the bootloader, I inadvertantly erased instead of selecting the USB. Now, All I get when I try to boot up is the white ASUS screen with;
The Device is Unlocked
Android cardhu-user bootloader <2.0 e> released by "ww_epad-9.4.3.26-20120416" A03
Checking for android ota recovery
Booting recovery kernel image
My computer sees the tablet. The Device Manager shows: Asus Transformer Prime APX Interface
But it only shows up when I reset. As soon as I try to boot the tablet, it no longer sees it. I can't access the bootloader and Fastboot doesn't do anything except "waiting for device".
SO! If anyone can give me some help, I'd appreciate it. It's a puzzle for ya, anyway.
Thanx

sry to tell you, but doing a wipe in bootloader with a custom Recovery on is the totalbrick till now.
Except you have made the NVflash Backup before.
No Recovery, No Fastboot= You have to send it to Asus.
Sry

Fastboot not working after NVFLASH restore, unable to upgrade to JB bootloader!

Ok guys. I really need your help now.
I tried and tried again before posting but after searching on the entire forum I've not found the solution to my problems.
The situation is as follow:
After an Nvflash Restore I'm back to ICS bootloader and firmware.
ICS firmware boot well and I'm able to use my TF300TG without problem at all on ICS.
But now I want to upgrade to JB bootloader to run ParanoidAndroid.
If I Power + Vol.Down I can read:
"The Device is UnLocked."
"Android cardhu-user bootloader <2.10 e> released by "WW_epad-9.4.4.40-20120704" A03"
"Checking for Android ota recovery"
"Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK"
The problem is that if I wait the 5 seconds without pressing any buttons the Pad don't show me any choice and go straight to the next screen:
"Platform pre os boot configuration..."
"Cold-booting Linux"
And then I'm on ICS working firmware.
I CAN'T enter in fastboot mode. I'm only able to enter in APX mode with Power + Vol.Up
And last time I was able to upgrade to JB bootloader it was via fastboot flash. All other methods have always failed.
How can I restore fastboot on my Pad?

I've tried to download the "WW_epad-user-10.4.3.9.zip" file in my sdcard and the Pad recognize the update.
But after reboot the pad goes in recovery and after a few seconds I can see the image of the droid with the red "!" signal lying on the floor.
I've tried also with "dlpkgfile" file but maybe it was not for my version of the Pad -> WW 10.4.3.9 TF300TG
I don't know what else to do..

Ok. Now I'm back on fastboot.
I've nvflash restore using a blob file of last update "WW_epad-user-10.6.2.6.zip".
This one directly boot into fastboot with Power + Vol.Down.
Unhappily the pad in this way does not reboot in JellyBean OS. It remain stuck during the second ASUS logo.
I can't go in recovery mode like this.
Only fastboot working this way but if I try to flash a blob file via fastboot the pad give me a message "insufficient memory" while trying to write the system..

Anyone can help me??

[Q] weird situation where i bricked, nothing fixes it yet.

tf300t
I was using energy rom, I am 90% sure it was the 4.1 version. (the rom folder was labed Energy.TF300.JB.11.30.2012.zip)
Today i tried to revert it back to complete stock. tried to flash the latest blob from asus' website using fastboot, and when it rebooted, i got the dead android logo, and then nothing. I then followed some other guides from here and such to try to recover it, and now I am stuck with it going straight into TWRP v2.3.1.0 recovery. It then asks me for a password. I can use the adb reboot bootlader command to get back to the fastboot screen, but anytime i try to flash anything, it never takes. the command window says it went, but the tablet just freezes up, until I hold down power until it reboots. Is there any fix for this? Or am I completely and utterly screwed? I will reply asap to any posts, so feel free to ask me for more info if neeed, ill answer the best i can.

Basically you have flashed a 4.2 bootloader onto a 4.1 recovery (TWRP 2.3.1.0)
Sorry but that is a brick.
If you had updated TWRP to a compatible version at the same time you may have been able to save this first ......
As far as I'm aware the only fix is to send it back to Asus for repair.

crap LOL. I got into fastboot, used fastboot erase system, and fastboot erase recovery. Now when i try to click any of the 3 icons, i get unrecoverable bootloader error 0x000000. I can still use fastboot tho when i reboot. anytime i try to flash still, the tablet freezes. when on 3 icon screen, it says at top left:
keydriver not found.. Booting OS
Android cardhu-user bootloader (1.00 e) released by "US_epad-10.6.1.15.3-20130416" A03
It there anything i could do at this point? It is not rebooting into twrp anymore at all. And if i let it boot normally, it just sits at the asus logo. Am i mistaken in assuming it is ready for an OS to be put on it?

Well any chance you had has now gone as you wiped from the bootloader which has now sent a message to the incompatible recovery to wipe and it doesn't understand the partitions so who knows what state it is in now. Sorry.

ok. well than you for your help anyways. everyone says search LOL, but everytime I try to do the things everyone says to they fail for me LOL.

Rooting instructions don't work

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.
