Check my signature for a link that includes much information about accessing apx.
I hope this helps.

Thanks tobdaryl
Ok have managed to get into APX Mode, However insted of showing up as NVidia APX mode device it shows up as Asus Transformer Prime APX Interface.
When I type "wheelie --blob blob.bin" it responds with error "Failed to open blob file blob.bin"
Is it the device driver that is the problem? After doing even more reading I don't believe it's that cause checking
the naked drivers inf file it matches with the PID & VID.
However had to pinch my wifes Sammy to remove their drivers as mine got wet a few weeks ago.but the device tree shows up as SAMSUNG Android Phone with the Asus Transformer Prime APX Interface under the tree.
Is blob.bin on the tablet? It boots with the correct message AndroidRoot 9.4.3.30r01 in top left corner.

The way the driver shows is not an issue. Many have reported that and used it with success. That is the price we pay for universal drivers.
wheelie --blob blob.bin
is in the list of files you should have created. Find them and place in your directory with wheelie.
NVFlash Files you should have created ( 8 total )
blob.bin
blob.txt
bootloader.ebt
create.bct
recovery.bct
bricksafe.img
factory-config.img
unlock-token.img
I guess I can assume they are in the folder with fastboot?
Looks like I spoke to fast.
Once your blobs have been generated you will need to retrieve them from the “internal” SD card from the AndroidRoot directory (e.g. /sdcard/AndroidRoot). You can do this either through MTP mode or by pulling them using adb.

Another Bricked TF300

Hi, good people. I have bought a TF300T bricked last week, the old user has stock OS, tried to root and failed.
Now im fighting with that. When i turn on the tablet, it stuck at 'The Device is Unlocked' with Asus n' Nvidia Logo, after a minutes it reset and keeps in a constant loop.
I tried to recovery [vol down etc etc] and no effect, i tried with a few of tutorial and nothing.
I connected the tablet via APX [VOL UP + power]. PC recognized it but i stucked in this. Tried to fastboot and stays in 'waiting device'
Someone with ideas? Thanks frr all and sorry for the inconvenience.

PC operating system?
Drivers for fastboot and adb loaded?
Look at my signature about universal naked drivers.
Also about getting into your bootloader menu.
APX will be useless to restore.

Did you actually use the link to attempt the bootloader access?
Did the drivers properly install?

I'll assume that means all ten methods to get into the bootloader failed.
If the adb drivers installed we may have a chance.
You didn't say about the sdcard.
At the moment are you still stuck in apx or bootlooping.
Sorry but I need a place to begin.

i have a sd, it doesn't have info [isn't from tf300, it doesnt came with]. When i introduce it into eeepad i can't access the storage from windows.
I can only interact with the tablet when i turn it on with VOLUP + POWER then is when windows ask me for drivers, now i have installed ADB drivers.
sorry for all dude. And thanks.

No problem we just need to get a starting place and have as much in our favor as possible.
I don't believe adb works in apx mode but we'll give it a shot.
No sdcards come with the tablet.
Go into apx mode (volume + power).
Go to your adb folder with cmd and type
adb devices - press return or enter
If it is working we should get your serial number in return.
Now get out of apx mode.
type
adb devices - do not press return yet
watch your unit and when the screen goes black and before it lights(rebooting) now press return
Tell me what is returned each way.

I have some bad news for you.
Without adb or fastboot access I don't know of anything else to be done.
If you could have gotten into the bootloader menu we would have had a chance.
Maybe someone else will read this thread and have more ideas.
I'm sorry.
Good Luck!
same problem here. i have a tf300t and can only access apx interface.
I got into this mess, after by "accident" choosed the "wipe data" option present on the bootleader.
!! adb, fast boot do not work!! "power key + down button" dont do anything!
i'm getting a bit resteless because no matter were i search on the web i can not find anything suitable on how to resolve this issue...
there are some youtube videos that show a solution for tf100. it seems the same problem.
http://www.youtube.com/watch?v=CwvfNIHCYlQ
there is also a tool for tf100, called easy flasher. to bad it does not work for tf300t
http://forum.xda-developers.com/showthread.php?t=1688012
i think it is a question of seaching and waiting. someone will help and get or point to a solution. because if we google for tf300t bricked that are lots and lots of links stating this issue...
what a mess...

Do you see anything after resetting by holding volume down and the power button? If you can get the tablet into fastboot mode you may able to revive it. If you can, ask the previous owner which version stock Android he was running before he tried to root it (it matters!).
This method worked for me!

[Q] TF300TG Stuck on Asus Logo

hi

these steps that i made before i asking for help
1. unpacked and got it with latest firmware 10.4.3.9
2. unlocked with asus official tool from asus support website
3. root by http://forum.xda-developers.com/showthread.php?t=2013792
4. device rooted successful and worked perfect
5. installed titanium backup and restored my apps from nexus 4
6. rebooted and continue work perfect
7. uninstalled asus stock apps and rebooted OK
8. at one moment battery discharged and device turned off
9. after hour of charging device booted and stuck on asus logo
now my problems
1. can't boot in any mode (pwr+vol down just restart device)
2. pc (xp, 7 x64, 7 x86) not recognize device
3. in apx mode (pwr+vol up) device manager see device and with Universal Naked Driver 0.72 seems ok
4. adb and fastboot = device not found
5. wheelie --blob blob.bin
Waiting for device in APX mode...
[=] Chip UID: 0x15d456d1557fa16
[-] Failed to read RCMVERS from blob file.
device one day old, and i too tired to continue read millions of forums with many solutions. all them starting with "fastboot" and fastboot can't see device....
so please anyone help me !!!
or maybe my asus tf300tg already in tablets heaven ?
thanks for any help !
hopes die last !
only thing I can guess if you still have the stock Recovery is trying the reset button on the left side under the external sd slot. But this can make it worth.
What exactly to do with reset button ?

Seems that you got a same problem as many others ( hundreds ) and as me too. If you are not able to access the bootloader but still have access only in APX mode than your device is soft bricked. To recover it is necessary to access the nvflash ( which is restricted by Asus) and rewrite the bootloader. To get access from Asus is posted an open petition here: http://forum.xda-developers.com/showthread.php?t=2119533 . Sign it and pray......
Sorry mate.

[Q] TF300t bricked? Bootloop, no adb, no fastboot but APX accesible

Hi everyone, first post here, but I've been reading this forum for some time now.
I've got an asus transformer pad tf300t 3 days ago. Last night, I tried to install cyanogenmod10, I unlocked the device, and installed clockworkmod, everything was fine until I accidentaly entered recovery mode and wipe all data, now the tablet only shows the asus logo and enteres in to a bootloop (I think). I can't enter recovery mode, ADB doesn't recognize it, fastboot neither and I can't even turn it off. I can't enter recovery, it just shows me the asus logo again.
HOWEVER, I waited until the battery drained, connected the usb cable to the tablet (not in the computer) pressed + volume button and without releasing it, connected to pc. Now the computer detects new hardware. I already installed the driver and it says "ASUS TRANSFORMER PRIME APX INTERFACE". Now, i'm not sure if it's the correct driver, but according to hardware administrator, it works fine.
Now, the real cuestion: Is there anything I can do from apx mode to save my tablet? A new bootloader maybe??
Thanks everyone
PS: Sorry for the bad english, It's not my language
from the loop,If you hold the power button for 10s when reboot and immediatly press the volume down button, what you have asus loop or the screen with the 3 icons (RCK ecc) ?

To answer your question about apx, no unless you received your tablet with ICS 4.0 and installed Nvflash.
Check my signature for a guide for apx and bootloader menu. Look below the apx section for the bootloader information. Try each from beginning to end except removing the back and disconnecting the battery. If you complete the list and still have not seen a change start with #1 and try them again and again. It is surprising but as you go through the list things have a way changing.
Good Luck!

Use of the bootloader information may allow access to recovery, adb, or fastboot. Access to any of the three may allow the ability to recover your tablet.

Of course, my tablet had the bootloop error with TWRP and the new 4.1.2 JB update.
When my device had stock ICS ROM (long time ago), I followed this tutorial, this allow you to create some backup files from your device, which in the future will allow you flash your tablet througth APX mode (more powerfull that fastboot mode) and the NVFLASH utility
http://forum.xda-developers.com/showthread.php?t=1894867
The only isue is that you need a pre-JellyBean bootloader (ICS) in order to make those backup files, if you are in a JB stock ROM (JB-bootloader), you can't make this backup files (Asus block the way that we can backup this files on JB ROMs).
With my backup files, the nvflash tools (from the tutorial above), and the instrutions that post tobdaryl, I manage to restore my tablet to an ICS ROM
If you are interested, there is a online petition (but i don't remember were :silly asking that Asus allows the NVFLASH backup utility on JB-bootloaders. With NVFLASH and ours backup files, we can restore our devices from any type of soft-brick.
In the case that your TF300 had and stock ICS (or you can flash it one), I can assist you in the case that you have troubles making the nvflash backup files with the tutorial
Would be nice if you could use someone else's file to fix a brick. Has anyone tried it.

If you cannot access to fastboot, IMHO there's nothing you can do. I am in your same boat: no adb and fastboot access, my PC recognize the tablet only in APX mode but with NVflash I cannot do anything because I not have a backup.
Bye
EDIT: I am in this situation after a wrong recovery flash. I flashed a new recovery but I could not load it and I made the (big) mistake to try a wipe from the recovery menu. My Tf300t is now stuck at asus logo and I cannot access to the bootloader anymore. I do not know what to do, is the tablet definitely bricked or there's something I can try before going to ASUS service?
Thanks in advance.
Bye

APX Drivers?

Anyone know where I can locate the APX drivers for the Tf700?
I've scoured Google and the only reference I could find linked to a file that was removed.

What is exactly "didn't work"? You can't install on your OS or your OS still can not recognize your device...
What OS are you running? I just want to know more information...
I couldn't get the universal drivers to work on win 8.1 either - even starting it in test mode. Yest to find apx drivers that work with it

Win 7 64.
Device originally detected as APX but with yellow !. Then Windows installed it as "unknown device".
Uninstalled that from Device Manager and rebooted. Connected tablet and get "unknown device" again.
When I try to update driver to those in link it says "best driver already installed"
Just tried those drivers on my notebook (fresh install of Win 7 64). Same thing - Unknown Device.
Think I have to face the fact that my tablet is bricked

Why is it bricked? Can you boot into your bootloader? What is exactly you want to do to your device? Maybe, someone can help you if you can tell us more details about your device. Your bootloader version, ROM, kernel, stock firmware, and your current state of your problems...

I attempted to update my CM10 ROM to CM11. Went through the process of upgrading CWM via Clockwork ROM Manager but I suspect that it didn;t work.
Booted into CWM, did a factory reset and Dalvik Wipe. Then attempted to install the CM11 ROM. It failed (can;t remember th exact error).
After that I could restart into the recovery menu (3 icons) - but the next time I tried to restart I ended up where I am now.
Endless loop of the Asus logo with the "device is unlocked" mice type - that's the only screen I get.
I can get into APX mode (I think) but when I connect the tablet to a PC it's not recognized.
Can Asus do a factory repair? I know I'll get cahrged for it but at this point I have a near mint tablet, the keyboard and very expensive leather case that's just junk if not.

I think that I know why your PC did not recognize your device... Do you know how to use ADB? What is happening when you enter "adb devices" in your adb prompt? Does your Asus screen have a spinning circle under Asus logo? I guessed that you are stuck at the bootloader screen and waiting for your OS to start so there is no spinning circle...
Please answer those questions above and maybe some experts can help you out... Good luck...

No spinning logo.
adb devices =
* daemon not running. starting it on port 5037 *
* daemon started successfully *
List of devices attached
Then command line

Oh well, you can not boot into your bootloader and can not get adb running. I hope that someone or experts can jump in and give you some good advices... Maybe, _that, sbdags, lj50036, and berndblb are actively helping users around here... good luck...:fingers-crossed:

Did you have adb and/or fastboot working prior to this? Meaning, are you sure you have the necessary drivers installed?
Although, I'm afraid neither would help. You probably would not get an ADB connection since you can't boot Android nor boot into recovery or access via fastboot.....
The APX drivers would not help you unless you generated your device specific nvflash blobs prior to this disaster. Without them APX is useless to you.
But before you turn it into a paper weight I would make each and every desperate attempt to revive it I could think of.
For example:
Holding Power + Volume Down for 30 seconds or longer
Volume down + reset pin hole on the side of the tablet
If you have ADB drivers installed: Connect the tablet to PC, type: adb reboot-bootloader and reboot it - hoping that you get a second or two where ADB would connect during the next boot (very slim chance but what the heck...)
Connect the tablet to the wall wart, let it boot to the Asus logo and leave it there. Overnight for 8 hours or so (I have seen this working twice actually - although the situation was somewhat different...)
Beyond that it's prayers, voodoo or replacing the mainboard - sorry.

Thanks!
I'll give these a try tonight.
I see a bunch on eBay for under $250 so I imagine it would be cheaper to just ditch this one if I can't get it working as opposed to sending it back to Asus for repair.

I believe Asus charges $300+ for replacing the board, so yes, you're probably better off buying it on ebay.
Just don't ditch the old one too far - you may need the parts. Or you can sell them

Well struck out on all accounts (I had left it plugged in at the Asus logo last night).
Appreciate all the help but I think it's eBay time for whatever I can get and sell the mobile dock and fancy leather case.
Then to decide what brand to get next....

Hi berndblb,
How are you these days? If vexille can get adb going, he/she could try to push the Asus firmware to the staging partition using dd command and hope for it to reinstall the bootloader....
@vexille
If you somehow can get into the fastboot mode, you may want to keep your device in that mode until you can successfully flash the new bootloader on your device. Good luck...:fingers-crossed:

I've tried every suggestion and cannot get past the "device is unlocked" mice type and static Asus logo.
When using adb it doesn't find any devices. I'll be putting it up eBay tomorrow for whatever I can get.
Looking at the new Samsung Galaxy 8.4 Pro as a replacement.

Hi LMK - you can't win'em all...
I'm good - just returned from a family visit to Germany. Fighting the jetlag - groan. And having to go back to serious work Friday - big groan.
So what did you replace the 700 with - if anything? I get you're snatching it away from your nephew once in a while to do some testing? What kind of a uncle are you? You are probably ruining all his game scores! LOL

I hope that you had a great time with your family... I am still looking and have not decide it yet.. I always backup my stuff before messing with the device. Plus, my nephew has a few hour of playing on the tablet per day any way.. So I can take it any time that I want, hehe....:laugh: I also have a higher authority as an uncle...:silly:

easyflasher stucked on NVflash

Hi there,
a friend of mine, gave me this tablet because was bricked. Now i have tried the famous easyflasher with his "flash default stock" ability.
I have already installed the naked driver on my pc, and the tablet in apx mode is correctly recognized by windows.
Via easyflasher i have already started the flashing of the recovery "RogueXM Touch v1.5.0-R1" and now i'm going to flash the stock rom.
All goes pretty well, but at this time the process is stucked on the screen:
"""""
Nvflash started
[resume mode]
"""""
The tablet is still recognized by windows (i can find them on hardware connected).
So the question is: it's normal that the Nvflash take long time, and don't give me any output on his work? Nor if it's going to do something?
Let me know.
Thank you...
