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

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!

Well my dumb fast moving self has backfired once again. While using chain fire 3D I have now got myself stuck in a boot loop. I have tried wipe data both from menu and from paperclip. I have tried getting latest firmware from asus site and using RCK but for some reason it just shows me a dead DROID. So any tips would be great I can't send it back because it's unlocked and rooted. So if anyone knows of a way to get RCK or the wipe data's to work I would be forever in your debt

You have to flash TWRP recovery via fastboot. BUT, be sure to flash the correct version of TWRP. Flashing the wrong TWRP recovery blob can brick your tablet.
Since, you did not mention the firmware version running on your tablet, we can only guess...
If you were on Android 4.0.x (also known as Ice Cream Sandwich or ICS), you need to flash TWRP blob with "-ICS" suffix. For example, openrecovery-twrp-2.4.4.0-tf300t-ICS.blob.
If you were on Android 4.1.x (also known as JellyBean or JB) before ASUS firmware version 10.6.1.8, you need to flash TWRP blob with "-JB" suffix. For example, openrecovery-twrp-2.4.4.0-tf300t-JB.blob.
If you were on ASUS firmware version 10.6.1.8 (Android 4.2.1) you need to flash openrecovery-twrp-2.4.4.0-tf300t-4.2.blob.
If you were on ASUS firmware version 10.6.1.15.3 (Android 4.2.1) you need to flash openrecovery-twrp-2.5.0.0-tf300t-4.2.blob.
And, if you have TF300TG model, get the TWRP blob with -tf300tg-. Once again, flashing the incorrect TWRP can brick your tablet. So, please be extra careful.
To download the necessary TWRP recovery blob files, and for the instructions on how to flash it to your tablet, visit the TWRP official website for TF300T(G) here: http://www.teamw.in/project/twrp2/97
After flashing the correct TWRP recovery, you can now launch the TWRP recovery via RCK. From there, you can flash ASUS stock firmware to fix your bootloop. I would recommend following method 3 outlined in the GUIDE found here: http://forum.xda-developers.com/showthread.php?t=2187982
How is this supose to work if my RCK always shows a dead DROID. And how do I get fast boot to work when fast boot freeze when I click the usb icon
"If you were on Android 4.1.x (also known as JellyBean or JB) before ASUS firmware version 10.6.1.8, you need to flash TWRP blob with "-JB" suffix. For example, openrecovery-twrp-2.4.4.0-tf300t-JB.blob."
I believeThis is the Firmware i was On but im still not sure how to get fastboot to work. or RCK
EDIT: Seems that Link you provided to learn how to put the recovery on is out of date,
EDIT II: "You will need fastboot for this method. Download the above file, check the md5, rename to twrp.blob and put the file in the same directory as your fastboot.exe (unless you have /platform-tools in PATH then you can flash from anywhere). Turn off your device and boot to fastboot (power on while holding volume down, then select the usb icon and hit volume up to confirm). The device will now be in fastboot mode. Plug the device into your computer. Run the following command via the command line:
fastboot -i 0x0B05 flash recovery twrp.blob" - Will ya translate to english , And as I said when i go into fastboot mode and click the USB icon it freezes.
EDIT III: 10.4.2.20 is my model # i belive
EDIT IIII : Downloaded fastboot But cant run it . i open fastboot and it just closes. Any ideas?
Hi folks,
I have been using Acer A510 for almost 1 year now, and upgraded 7 months ago to the latest JB OTA. I haven't ever rooted it.
Since 2 days, it can't boot suddenly, stuck with the following error message:
Booting failed

After a bit of Googling, I tried to unlock the bootloader, as a way to recover the tablet. But that keeps failing as well:
[ [email protected]: /tmp ]# fastboot oem unlock

Click to expand...
Click to collapse
At this step, I can see the unlock icon and played with Vol+ and Vol- to quickly select the "Unlock" option, and this is what I get on the tablet:

And on the computer (kind of error messages that are of no help):

So it appears the bootloader can not be unlocked, and I can not even enter the recovery.
I've read somewhere that it may be possible to recover in APX mode.
So is there any way to recover it (either through the bootloader or through APX mode)?
Thanks for your help!

I get exactly the same problem this WE :crying:
I never root/flash/play with recovery or anything else.
Tablet shutdown by itself, then after restart I get trouble to boot :
First the Android said it was unable to start due to encryption : "encryption unsuccessful > need factory reset". Even if I NEVER activate encryption !
I try couple of reboot without suceess, then now it stop on Acer logo and go to fastboot mode at each startup.
Then I have exactly same trouble : impossible to unlock bootloader using fastboot.
No way to flash something.
Need help !
If fastboot is available, you can try to boot CWM Recovery or TWRP recovery
fastboot -i 0x0502 boot C:\....\cwm-recovery.img
From there you can try a factory reset

It doesn't work as the bootloader is still locked !
Code:

And it's impossible to unlock bootloader as describe in the post.
Any other idea ?
You can try to download the full ROM from acer Web Site (GEN1 or CUS1 depending on what you had before)
rename it to update.zip and put it on your sdcard
Reboot your tablet in recovery if you can to flash it, or in bootloader (don't remember if the Acer bootloader can flash an update.zip)

Its 2015 now but i will post this anyway..
Try this
1st, Boot into recovery:
- Press [vol-] + [power]
- Once the tablet vibrated, let go [power] and keep [vol-].
- Now the tablet vibrates a second time, let go [vol-] and press [vol+] quick
- Once the text that appears on the screen ("loading recovery kernel image"), let go [vol+].
2nd, choose "Wipe data cache & factory reset" via volume rocker and power button to select it.
3rd, choose "reboot"
I solved mine using that steps, hopefully it will solve yours.
Thank you very much!!! It worked for me!

Hello everyone, it may be late for you but i found a solution for a bricked A510 :
for my part i only had access to bootloader unlock and fastboot, but it didn't communicate with my laptop
So i found a software called DriverHub and launched it with my A510 connected to my laptop
It found the right driver for it (was not the of from Acer or any universal ADB driver) and i could use the fastboot mode to unlock OEM and flash TWRP, and now i have Cyanogen running on my tab who came back from dead
Here's a link to the software : www drvhub net
Have a nice day
Hello Everyone,
I am a new member learning android. I bricked my tablet TF300T I want to make my situation clear and quick.
My TF300T had android 4.1. The device is unlocked and rooted. I was trying to load Jelly bean / Kit Kat on my Tablet.
Current Status
1) boot loop
2) no usb icon (by pressing volume down + power)
3) Device not detected by PC (fastboot stuck at : < waiting for device > message)
I can only see the below message (when pressing vol down + power), cannot go anywhere.
The device is unlocked
android cardhu-user bootloader(2.10 e) released by "WW_epad-9.4.3.30-20120604" a03
checking for ota recovery
Booting recovery kernel image
(device reboots at this point)
What I was trying before bricking
1) Copied the "TF300T-WW_epad-10_6_1_27_5-UpdateLauncher.zip" file to microSD card. Managed to get the prompt but firmware update failed.
2) used ADB fastboot and TWRP. I lost the usb icon (Volume down + power)
3) one of the xda-developers thread suggested that I copy the zip file to the root of SDCard. After that the next reboot brought me to this boot loop. All I see now is "The device is unlocked" message".
Please help me unbrick my tablet. Any help is appreciated.
Below a link to solution but myself haven try it before. Why not give a try and let us know.
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Well I went to install OmniRom 4.4.2 in my TF300T and when I reached the step to fully wipe it from recovery I did that and it took too long so I tought that it hangs up so I switched it off now everytime I try to boot it up it go on the Asus logo screen with this device is unlocked and then boot to the TWRP logo and stays there looping on it. Whenever I try to switch it on it will auto boot up and go all the way to the TWRP logo again.
What works?
From the TWRP Logo my PC is seeing my device and I installed the drivers from the Universal Naked Drivers but only ADB commands work
When I type: adb devices
It will write me this:
[device code] recovery
but when I write: fastboot devices
it will write nothing
I can also hold the volume up + power button to boot in APX mode.
In Short:
ADB commands working
APX mode working
Fastboot commands not working
My device got no bootloader now I think since I wiped it. Can I re flash recovery using ADB only withotu Fastboot?
Also I don't got any Nvflash blob files backups for my device :/ is it possible to use someone elses blob files? my SKU is WW.
(If possible pls tell me where to download the blob files and what steps I need to take.)
Or just put my tablet in the bin?
Thanks and hope I fix it pls reply.
Using other nvflash backup files to restore bootloader is possible, but not fully legal (and no one will help you, hopefully i'm working on it and i'm going to restore backed up files from other tablet)
If you have adb connection you can try to use dd command to flash official asus firmware blob or flash twrp blob for your bootloader version (4.1 or 4.2) into mmcblk0p4 partition. Unfortunately flashing can go wrong and you can get only asus logo and working apx mode, or when flashing is finished you will not see moving bar under asus logo after reboot (what means flashing partition(s)).
