Hi.
I own a TF700T and seems to have bricked it. Last status was: I had the latest stock ROM with root running and wanted to get a CM11 based 4.4.2 image from here. I downloaded it and used rom manager to get it installed. But the install script failed at some point and I thought the recovery might be outdated. So I used ROM Manager to update recovery... I tried CWM and TWRP option. Finally I booted up into recovery trying again to install those damn rom - I used the option to wipe all data / settings from the main menu and tried again to install the ROM which again failed (I do not remember the error message clearly). I gave up. I used the "reboot" option.
Now:
- Powering up gets me into the screen with the ASUS logo (left upper corner says "the device is unlocked"). Here it is stuck forever.
- Power + Vol-Down is same as just Power - I do not get into flashboot with those 3 small icons... I just get the ASUS logo and nothing else happens. Reset hole does not change situation. The device is pretty much "always on" now (till battery is exhausted) as long-press Power turns off and immediately on again
- Only thing that seems to work: Power + Vol-Up ends up in APX mode - my computer recognizes the device via USB at this point
Unfortunately I never did any set up to nvflash.
Do I have any chance to get this thing alive again?
Thanks a lot in advance,
q2.

Unfortunately ROM Manager does not work with the TF700 and you are not the first one to find out the hard way...
If you cannot find a way to boot into the bootloader to have fastboot, there's nothing you can do anymore without the NVflash blobs.
Did you try holding Vol - and then pressing the reset button in that little pinhole on the side of the tablet?
If you have ADB drivers installed on your PC you could try if you can establish an ADB connection at any point. If you did, you could issue the command: "adb reboot bootloader", which would enable you to flash a recovery and/or bootloader. This probably won't work since you need to be in the recovery or have Android booted for ADB to work, but worth a try anyway...
Admittedly these are very thin straws - but what have you got to loose?
Also: Just a few days ago a user here was stuck on a bootloop to recovery and couldn't get out of it. He left it alone overnight and all the sudden the bootloop sorted itself out... I have no explanation for it and it is unlikely to happen in your case, but you never know...
Good luck!
Thanks for replying.
Yes, I did keep Vol-Down (means Vol-Left) pressed while pinching the reset button. It did not help.
I will experiment a bit more. It's not really a boot "loop" - it gets stuck at the ASUS logo and this does not change anymore. Not overnight.
So far I could only see it being recognized as USB device in APX mode. Can you give me a bit background here? I have nvflash here. The blobs are not available anywhere on the net? Or why is that all a big fuzz? I used to have a Notion Ink Adam and APX saved my life several times, but the blobs were available to everybody. Nobody has the blobs here? Or are they device-specific?
I cannot believe that a today's device with a non-bricked bootloader and working APX is totally lost and even the manufacturer will only offer a costly RMA to replace the whole mainboard!?
Best regards,

For the TF700 the nvflash blobs are device specific - sorry.
Damn. That was the only answer I didn't want to read
Thanks a lot. So chances are gone, only RMA could help... I will ask friendly at Asus what costs they will charge...
q2.
Update:
Reply is here.
They only want to exchange mainboard. They of course know (and it seems that this is the only thing they know) that my bootloader was unlocked, therefore this is no case of guarantee for them. I know, I wrote to them that I just want to know how much they wanna charge me to fix this issue.
But: they don't want to tell me how much. They say they do not even know which revision and what hardware is inside my tablet, not even from my serial number. And I must first send them my tablet and they will charge me 95 Euro to check what's going on. And then they will tell me how much it will cost (and according to other threads I saw prices of over 400 Euro for a mainboard change - the TF701 successor model cost 450 Euro new in store)...
I somehow feel the need to reply that if they would've put only half the energy the put into logging who has unlocked the bootloader into the fact of making APX usable as a emergency recovery (as obviously not even Asus is able to generate a working blob for my device), they would have higher customer satisfactory statistics. I still just cannot believe a today's device lacks of all recovery options after a bootloader fails for some reason - as well as I cannot understand why Koush did not display a warning in ROM manager if problems are known to the community with this specific device (I mean the problem did not arise last week and ROM manager had tenths of updates since then).
I know that in the end all was my fault. And all flashing is done on our own risk. I will have to deal with it.
Phew...
Unlucky. It should be be stickied here somewhere that ROM Manager bricks the TF700 but then there is no guarantee it would be read. It is well known on this forum but that doesn't help people that don't visit frequently.
You can replace the mainboard yourself fairly easily. Watch the you tube vids on how to do it,. That is what I would do if I was in your position.

Unfortunately I'm stuck in same boat I tried to wipe out settings completely and clockwork mode was stuck and I was able to wipe recovery with TWRP or so I thought tried to reboot into recovery got stalled and now stuck on asus screen. I'm not opposed to buying a new motherboard but I find it very hard to believe that no one has come up with a solution to flashing the mainboard with the original firmware. I'm tempted to ask asus but I know the bill will be more then the tablet. Did you find an easier solution or do I just have to swap out the mainboard?

Thanx, but it seems like to backup blobs I have to do the very thing that will risk me needing backup of my blobs? ... install a custom bootloader before I have a backup?
Is this right?
Is this a safer method?

That's correct. You have to flash a modified bootloader and recovery. Done correctly this is not risky at all. But if there is a single line in the instructions you are not sure you understand, you are not quite ready.
There are quite a few tutorials on flashing in fastboot on this forum. Read them.
But generating your nvflash blobs you have to do without a safety net. It's worth it though! I have become much more adventurous with my tablet since I have the blobs squared away...

How do you define risk?
Flashing a bootloader (without having nvflash access) is always risky by my definition, it *can* permabrick your tablet if something goes wrong at the wrong moment. But it's the best we have.
Hello Guys, Im new in the foro and I would like to have your help! Due to I called Asus Official Service in Argentina and they wanna charge me with a 100 USD for soft services out of warranty.
The thing is that my dad put a MicroSD card in his TFT700t and when he whipped it out (without proper procedure), the tablet showed the following sign "Encryption unsuccessfull" and when you press "reset tablet" button, Android start thinking (5 seconds) and then you receive the error screen.
"Encryption unsuccessful
Encryption was interrupted and can't complete. As a result, the data on your tablet is not longer accessible.
To resume using your tablet, you need to perform a factory reset. Whn you set up your tablet after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account"
And a "Reset Table button"
When you hit it... there is an Android Robot image that says "Installing system upgrade" and 2 seconds later you have a Dead Android Robot with a ! sign and it says "ERROR"
I have triyed the following things:
- Hard reset by putting a clip on "reset switch"
- VOL DOWN + POWER BUTTON and Android or Wipe Data option... neither worked out.
- VOL DOWN + POWER BUTTON and put Asus Official firmware on a SDCArd renamed "EP201_768_SDUPADTE.zip"... then choose RCK option (I do not have USB Sign button).... nothing happend... the tablet looks to reset, and then they start again with "Encryption Unsuccessfull"screen.
- Finally I tryed to use Minimal ADB and Fastboot, but I used some commands to load firmware from Asus and reboot it and nothing... still the same screen.
As I said it is my old man tablet... it is standard as hell! Stock firmware, not unlocked, not rooted!
When I get into bootloader it shows:
"Androi cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.1.14.8-20130514" A03
Key driver not found.. Booting OS

Im freaking out!! Would you please help me? I really want to fix this problem for my dad.
Thanks dudes!

Sorry for not labeling it properly. It is the latest version listed in the Dev section. I have been on custom Roms since day one and have never had this issue with any device. The button commands to get to recovery or fastboot seem non responsive and it will boot through a splash screen for the OS and then give this screen (sorry stole the pic from someone else having the problem on a phone, but the text is the same). My PC can see the tablet when it is in this state, but adb commands to reboot to fastboot just loop back around to the same Encryption failed screen...

Try to boot into fastboot: Hold Power and Volume Down buttons until you see three icons.
If you can get into the bootloader (see above) you have a fighting chance to get this solved. Although I have not tried the fastboot/adb commands I have in mind on a locked device. No idea if they would work but no harm in trying.
You can also try to get adb access while in recovery, but you need to set up fastboot/adb on your computer first.
Let me know if you need help with either.

I have an Asus tf700t that i rooted a long time ago and was running Cromi-x 5.something. I also have TWRP recovery installed.
I can't even remember the details now but at one point about 12 months ago, i when to do a wipe & flash (which i did many times and I felt very confident doing with TWRP) and something went wrong.
All my tablet does now is turn on and flash at the TeamWin screen, that's it. I've allowed for the battery to drain, I've attempted holding the volume key in to boot into recovery, I've removed the SD card...nothing seems to get me un stuck.
I attached my tablet to my pc (which now is windows 8.1 x64) and all I get is an Unknown Transformer device. I have attempted to download and install the google SDK kit along with the original items i used to root my device, none of them seem to "click in".
Am I looking at a dead unit here?
cheers,
Dave
Did you use Wipe Data from the bootloader menu?
If yes, you may be in a forced reboot to recovery loop.
First thing to try is to connect the tablet to power and leave it in TWRP. If you're lucky it'll sort it out and eventually execute the wipe data command. I would leave it for 8 hours or so....
Can you get into the bootloader = fastboot mode?
When in TWRP do you get it recognized with
Code:
adb devices
?
I have messed around with all my electronics in the passed, rooted them, put custom roms etc. with no trouble. So after getting frusterated with my Asus TF700T, I decided it was time to put Cyanogenmod on it. I read up on the forums and it recommended TWRP, I have always used clockwork mod but because TWRP was recommended I used that. I followed the directions and rebooted to the startup and it is stuck on the Cyanogenmod startup screen. So thinking that maybe it was just taking a long time because it was the first time, I waited and waited and waited. 24 hours later still stuck on the startup screen. I decided to try again, I pressed the power button and the volume down button and this is what I see:
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.14.10-20130801" A03

Than I have 3 choices to choose from: RCK, Android, and wipe data
When I press volume up once to select RCK I get a message stating:

After reading I decided to try tranformer tool kit. So I put the tablet into APX mode. Seems to work, tablet restarts with a blank screen, the computer makes the appropriate noises expected when it detects the tablet, but when I check ADB I get a message ADB is not working or communicating with your pad. Evidently I screwed things up somewhere but I don't know where to go from here... Please, If anyone can help, It would be so appreciated.
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
I sounds like the recovery flash failed. If you haven't already, I would try to re-flash TWRP through ADB and fastboot.
If you aren't sure how to do that through ADB use this post:
http://forum.xda-developers.com/showthread.php?t=2688891
Its the beginners guide in the general section.
I may be wrong here, but I've taken my TF700 from the brink of death and back again a few times.
What TWRP version did you flash and how???
The unrecoverable bootloader error is not good news. Usually you need a buster99 to get your tablet back - if you still can get into the bootloader and fastboot.
If you can, follow the instructions below to the letter (naturally you have to flash the TF700 system blob, not the TF300!), then flash a compatible recovery and a rom compatible with your recovery and bootloader. And if you're not sure ask first, then flash....

Ummmm let me take a wild guess what customer support will advise:
Sorry you unlocked so no warranty but send it in and for $300 we may repair it. If we can't we only charge you for shipping both ways.
Nice to see you, Asus! Where've you been the last 2 years?

Yeah - I had that dream too one time or another....
Hi all, I just encountered this same error message for the TF700T when going into fastboot mode
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.14.10-20130801" A03
Starting Fastboot USB Download Protocol
All I have done is unlock the tablet. I was on the "Practice/Background" step in berndblb's (awesome) custom ROM guide before starting to load up fastboot and adb, when I saw the message in the upper left corner. When I go into RCK, "booting recovery kernel image" then appears under the error message. After 3-4 seconds I get the dead android with "error!" screen. When I power off, the tablet goes into normal bootup and the stock ROM still works perfectly fine.
Since it does, is there something I should do to resolve this issue BEFORE trying to push TWRP to the tablet? Just trying to be prudent...
Many thanks,
MM
Every Asus tablet I have seen has the "key driver not found" on boot - ignore it.
The dead Droid also is perfectly normal. It's the stock recovery not finding a firmware file to flash. Just keep going

Hello,
Decided today after a couple months of non-use to fire up my TF700 and update it. The device has been unlocked prior and KitKat4.4.4 installed with TWRP 2.6.3 I believe.
Today I was going to put TF700 LP 5.1.1][ZOMBi-POP OMNI KANG RC2][DEC 10] on it.
Reading the instructions I saw I needed TWRP 2.8.7.4 so I booted into Fastboot and was able to load this img file.
After that I could no longer go into Recovery. It just hung on RCK (stopped flashing) and a power off was all I could do.
So then I notice that I was supposed to have boot loader 10.6.1.14.10, mine was 10.6.1.14.8.
So I believe I downloaded a kernel file instead of a bootloader and probably uploaded the wrong thing to the boot loader.
Now upon powering on the device, I see "The Device is Unlocked" at the top left of screen and the ASUS and NVDIA logos and that is all it does (regardless of the power/dn vol combo).
PC does not recognize anything is plugged into it (I assumed it wouldn't)
Any hope here, or should I toss it? (sad as it was working good, just wanted to update it).
Thanks.
