signature Mismatch
Unrecoverable bootloader error 0x00000008
is this unit dead & not fixable?
I bought from Amazon so maybe returnable? if not fixable, had for a week now.
If you can't get into fastboot or recovery then it is hardbricked.

have never used fastboot icon but it dont boot that far for the icons to show anymore.
but no recovery as it can't continue far enough for TWRP TeamWin splash screen to show up
as i guess the bootloader needs to work to get past this stage.
as far as I read there are no fixes for bad bootloader. but this was posted in feb & march of 2012 so I was hoping for new info & maybe a fix.
this is most probably the reason why asus voids your warranty when you unlock. I dont trust any other recovery than ClockWorkMod.
Maybe toggle signature verification to disabled? Or if your able to still go into recovery, sideload the latest firmware from asus site and flash it from recovery?
..........
Sorry just read the above comment... Hopefully someone here can help you out. Good luck to you!

Would have been nice to have a backup bootloader, holding down buttons to switch to & repair
if asus can repair im sure there is a way.
I am not able to get into recovery any longer.
seems like the clockworkmod has an option to disable signature option, but I can't even get to twrp
I made a big mistake & did this flashing AOKP 4.1.1 with twrp I think it wiped the twrp recovery app & messed up the bootloader now.
im sure there is a repair for fixing the bootloader as if it is sent to asus they can repair it for like $50 ;(
Any steps to take to help repair this would be great

your issue was with the pre alpha AOSP rom, not with the TWRP recovery. TWRP recovery also allows no signature checking.

cool, nice to know.
seems there must be a way to do something as if you hold the right vol button + power it connects to PC & shows in windows 7 Device Manager
but not the same as if the system was booted in to android as it shows the internal & sdcard. this dont show the interal or sdcard but shows it's connected. wonder if asus connects to the port where the charging cable or dock go's to repair bad bootloaders.
tried adb.exe devices but it dont show anything connected still. even tried the asus android bootloader interface 4.0.0.5 driver.

I'm really sorry this happened to you, but you probably knew you were venturing into very untested ground.
Are you posting in the Pre alpha AOSP thread? That might be more productive for you. It seems there have been at least 3 hardbricks from flashing that rom.

This does not sound like a recovery issue, but rather a bootloader checksum failure. I know you are probably not bashing TWRP, but it should be noted that this NOT a borked recovery

Accessing the bootloader on phones is done at a much lower level, not sure about tablets. JTAGing is usually the way bootloader is restored when hard bricked (a serial connection). I have been googling just to see what is out there... but pretty limited info on bootloader recovery/overwrite for any of the asus tablets.

Keep digging. The fact that your PC can see the device is a start. Does win7 load the device drivers?

Im not bashing anyone or any product, was my fault, no one elses. I have been modding for 20 years & should have known better & done more research into what I was doing here. We are warned all over these forums that everything we do is a risk. you dont blame anyone but your self.
JTAGing would be the way to repair, I agree, I just haven't found anything for the transformers yet. been looking, but nothing out there that someone has connected & got to work. just talk about jtag & transformer. there are some arm7 jtag programmers im sure some software could be made, but I think we are far from knowing how to talk to the bootloader in a low level, im sure some are trying to reverse engineer to get to the boot loader.
yes, windows loads the drivers when you hold the right vol button + power. you hear it connecting if windows 7 has speakers on. the drivers do have to be installed for this to work, I think the device is called APX in device manager.
I have posted in the other forum about this, but like I said above, not a products fault.
I would like to thank everyone for there input.

The Volume Up + Power button combination allows you to put the device in APX mode but it's still useless without a working NVflash solution.

thanks for the info Pretoriano80
I will keep researching for Jtag & bootloader recovery & waiting for nvflash to be ported to the transformer series Doesn't even seem JTAG would even be needed just a port of nvflash, jtag would be a marketing thing most likely after reseaching other tablets that have unlocked bootloader, they just use nvflash if im correct in my finding here. as if it can be fixed down the road then no worries anyone would have as it could be fixed if a JTAG or nvflash portedwas made, bought & was plug & play install not taking apart tablet, just plug into docking station port & plug usb cable to computer install drivers & JTAG software GUI interface software made for windows 32bit & 64bit plus Linux support also or just nvflash ported. im sure there are people already looking into this.
I sent back the unit to Amazon will get another unit late thursday.
I think I will only root this unit, until I understand & research more on Android devices like I should have from the start my mistake, No one else, as this was my fault & no one else.
everyone should know everything is at risk, if the bootloader is unlocked. my new replacement will only be rooted, till I see a must have for a unlocked bootloader. rooted seems to be a must have. but not a unlocked bootloader at this stage of the transformer. maybe at some point down the road, it would be a must have, but time will tell.
:fingers-crossed: Let me know if any of you are looking into JTAG & or nvflash for the tranformer, im sure nvflash is the way to go & not jtag

Is there a version of cwm yet? Although it has some really great features, I still don't quite trust twrp after causing all of those soft bricks after recovering by not properly restoring /boot

Thread cleaned. Take the fighting out to the parking lot boys....
So I made the mistake of installing Clockwork recovery mod when I installed Rom Manager on accident. Stupid mistake. I tried getting into recovery after that and it would hang right after pressing volume up at 5 secs. I did a normal restart of the tablet and decided to do a factory reset and see if i could restart with with and install TWRP. I ran the factory reset and restarted my tablet when prompted. This is when the issue started and now I'm stuck at the boot screen, the first screen you see when you start up. So i tried to start it up into recovery and it still wont budge. whats weird is it doesn't ask to press vol up it just says "Android cardhu-user bootloader <2.10 e> released by "US_epad-9.4.5.26-20120720" A03. Checking for android ota recovery. Booting recovery kernal image." Yet nothing happens. So am I bricked... is there any way out of this. My bootloader is unlocked and i am rooted... am i screwed? I read somewhere I might be able to fastboot, but is that possible if i cant get into recovery?
UPDATE: After doing some research I discovered that it might be possible using the NVflash method using site below but unfortunately NVflash is not compatible with the tf700 atm. Meanwhile I have submitting a ticket to asus but i do think NVflash would be my only hope if it actually worked for me.
androidroot.mobi/2011/06/13/nvflash-on-asus-transformer/
NVFlash will *not* work on the TF700 - others have tried - it will probably make your situation even worse.
I don't know the answer to your question off-hand, but I'm sure someone will be able to provide a method to get you back up - just stay away from NVFlash on the TF700...

Reading through different forums I have read problems similar to mine but nothing exactly the same. I followed each fix anyway but I have not been successful.
The last thing I remember I did before the brick, I flashed CWM touch then CyanogenMod 9. I am unsure what occurred but I tried to flash back to my JB backup and the problem started.
Now my tablet comes on and just hangs on the Asus splash screen. If I turn the tablet off, it automatically comes back on.
I have tried to turn the tablet off and boot into recovery but it just boots back up to the splash screen and hangs; I have no option to go into recovery, android or fastboot.
I can get into what I think may be USB mode by pressing power and volume up through a couple of cycles; my computer detects a device but I cannot load drivers.
I have downloaded the Android USBPCdrivers but each time I try to navigate to the folder to install the device manager fails.
If anyone has any thoughts I would appreciate any assistance, thanks for your time!
UPDATE TO ORIGINAL POST
I as able to finally get my computer to recognize the tf300t in device manager by wiping all the usb drivers and installing "Universal Naked Driver 0.7" posted by 1wayjonny from XDA's website http://forum.xda-developers.com/show....php?t=1766220, not sure if it matters my computer "sees it" as a ASUS transformer prime rather than tf300t.
Now I am reviewing an ASUS unbrick called Wheelie http://forum.xda-developers.com/show....php?t=1687285, I believe this is geared towards the tf101. Anyone have any thoughts based on my status at this point? Thanks
If you are on JB stock, there is no way to flash a booting Cyanogen 9 ot 10 Rom.
Only Hydro JB is running!!!! And JB Stock.
1st of all you have to download a special Recovery. I highly recommend TWRP. You have to dl the JB version!!!!!
Flash it through fastboot. Then flash the Stock JB via TWRP recovery
Then flash TWRP again via fastboot.
Than flash The Hydro JB rom
Then reboot
Then go back to recovery
Then flash the latest Hydro update and reboot
You are like me stuck on the f...... new JB Bootloader and Kernel. All other roms are for the ICS Bootloader and Kernel, so no way of getting them running until the Cyanogen devs finding a solution.
Fastboot not an option
Thanks for getting back with me.
Fastboot is not an option for me; the tablet hangs on the splash screen.
I can get into the usb mode but I am unable to locate any APX codes to push anything over. The only codes I can find are for tf100 & 200 moddels.
Any thoughts?

You're hosed.
The developers that worked on the prior TF units' nvflash said the development isn't done on the TF300 yet. And, even if it was, you needed to perform some steps prior to bricking the device to make APX accessible after a brick. If your device is bricked already, your only recourse is to send it to Asus and eat the $197 fee to have your motherboard replaced.

i have the same problem, and only APX mode is accessible, (no fashboot, recovery..) can get chip ID from APX mode, that is all,
should i wait for the nvflash rom(about 3-4 weeks, is that right?), or paid for this? (replace the motherboard)

Waiting for nvflash won't do you any good since you needed to have it BEFORE bricking your tablet. If your tablet is already bricked, APX/nvflash will not help you.

He could still try sending it for RMA. Mine got repaired for free for some reason.
An unusual Asus 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
As your last resort, this worked for me

Hope it helps, feel free to ask anything.
I bricked a TF300T today, and I'd like to know if there is possibility that it might be repaired.
I was attempting to install CyanogenMod 10.1 on the tablet for my friends, which I offered to do since I have a bit of experience doing similar on other devices. It was running Android 4.2, and had the latest firmware (v10.6.1.15.3, WW). After researching the XDA forums, I unlocked and rooted the device, and installed the TWRP recovery (2.5.0.0). I used TWRP to flash CM 10.1 and the Google apps, but when I tried to boot I got stuck at the Asus logo. After some more research I realized that the official release of CM doesn't work with the 4.2 bootloader, and that if I wanted to install that ROM I would need to downgrade my bootloader (right?).
The trouble occurred during the downgrade. I downloaded the 10.4.2.20 firmware and used flashboot to flash it. The flash completely successfully and I was going to run "flashboot reboot." Thinking I'd save keystrokes on the command line, I hit the up arrow to call up my last command, and meant to delete the last half of it, but I managed to hit 'enter' instead, starting the flash over again. I cancelled the command (^C), which might not have been wise -- but then I made my dumbest move, and powered the device off. (I'm not really sure why; I guess I assumed I'd still be able to get into fastboot mode.)
Now the device will not boot at all, except into APX mode -- i.e., the screen is blank, but when plugged into the computer the device registers. From what I've read here, there isn't really anything useful I can do in APX mode, given that I never setup nvflash, and I can't figure out any way of getting the tablet to do anything else.
Is there anything I've missed? Is there anything I could accomplish by cracking open the tablet (popping out the battery)? I've seen references to replacing the logic board – would that work, and how should I go about this? I know most if not all of these questions have been answered in different places before, and I tried to do my homework, but I figured I'd ask in case anyone had new experience or expertise to share.
I think to only solution is to replace the main board OR buy a new tablet :'(

APX mode is useless without nvflash installed and nvflash can only be installed while on ICS and once you leave ICS you can't go back.
Some Info: the vehicles to recover without nvflash are
1. recovery - stock or twrp
2. adb
3. fastboot
Do any of these work?
Try this link to find ways you may not have used yet -to get to the bootloader - thus recovery or fastboot

For future reference here is the way I see the recovery and rom matching issue.
4.1 bootloader - 10.4.2.9, 10.4.2.13, 10.4.2.17, 10.4.2.18, 10.4.2.20 - twrp openrecovery-twrp-2.5.0.0-tf300t-JB.blob
4.2 bootloader - 10.6.1.8 - twrp openrecovery-twrp-2.4.4.0-tf300t-4.2.blob

Thanks for the response. I've already tried the relevant methods in the guide, except for disconnecting the battery. I can get into APX mode -- the tablet registers as an APX device when plugged into the computer -- but I can't get it to enter the bootloader, so recovery, adb, and fastboot do not work. At this point I don't have much hope that the device will ever boot again without replacing the motherboard.

Is there any tips for buying mainboard? Should it be exactly the same as in my tablet (I mean the same region and, therefore, version of ROM installed), maybe serials.
I have a bricked TF300T, and the only way I have to resurrect it - MB replacement. So, please, ANY info will be useful. Thanks in advance.
try to get it into fastboot somehow - i was stuck in apx too but with a bit of trying i was able to get to fastboot (try resetbutton + vol-down, let it completly drain of power, charge it back and try again)

I have the same problem...
My TF300T got bricked and now i cant boot at all anymore, i just see the Asus logo.
Vol down and power doesnt work but i think i can boot it into APX mode, screen stays black but my pc recognises an APX device.
At first my pc didnt install the driver but than i found APX drivers in these forums.
I've downloaded the APX drivers from a thread and i can choose to install various drivers, i tried all of them.
The one i think i need is the Asus Transformer ADB interface driver but this one along with every other one i can choose from doesn't work.
After installing and trying fastboot devices and adb devices i never had a device name show up
im kinda stuck right now
Can anyone please give me some advice ?
Cheers, any help is appreciated

Bought the Asus tab a year back and kept it original and updated by Asus for a few months.
Begin this year i unlocked it through a guide here on XDA (i dont thin through the Asus APK but another way).
After it succesfully unlucked (you could see "your device is unlocked" in the left top of the Asus boot screen i installed CWM.
After CWM i installed Cyogenmod 10.1 and kept it updated for months
This was all in the beginning of this year...
In june after updating Cyogenmod 10.1 to a newer version it wouldnt boot up anymore (i still had acces to my CWM recovery at this time).
So i switched back to the last working Cyogenmod 10.1 version (think it was 15th or 16th june).
I left it again for 2 months, still everything was fine till i saw that Cyogenmod 10.2 was out on XDA.
The upcomming is all last week;
First i tried to install 10.2 through CWM but my tab wouldnt boot up.
Than i switched recovery through fastboot because i have read that 10.2 was only compatible with TWRP 2.5+ so i got the latest TWRP
(2.6.0.0 i think)
After booting into TWRP i fully wiped the tab (i might have wiped everything because i dont know TWRP so well), after the wipe i wanted to install 10.2 again.
My tab still didnt boot so i got anctious and wanted to switch back to my latest version 10.1 (june 2013 that did work) so i could at least use my tab again.
Installing 10.1 again didnt work through TWRP, after that i came to the conclusion that i couldt install any rom anymore, at every rom i got an error in TWRP so i thought i had the wrong TWRP installed. (see my other post for a link to the screenshot of the error msge, i just cant find it atm).
Last but not least i tried to load my old CWM again as recovery, after i did this i couldnt get into recovery anymore...
Thans basicly the whole story.
Hope some1 can help me out.
Thanks in advance !
Cheers

Bought the Asus tab a year back and kept it original and updated by Asus for a few months.
Begin this year i unlocked it through a guide here on XDA (i dont thin through the Asus APK but another way).
After it succesfully unlucked (you could see "your device is unlocked" in the left top of the Asus boot screen i installed CWM.
After CWM i installed Cyogenmod 10.1 and kept it updated for months
This was all in the beginning of this year...

What happends when you press volume down+ power?
It jeeps rebooting or it goes to black screen? Have you tried pressing the reset button is below the micro sdcard slot.
You should be able to boot any recovery.
is I recall correctly cm switched partition layout to 4.2 on tf300.
if you still have fastboot try my guide to flash stock and then flash recovery and cm10.2. since it sounds a lot like my error I had with cm it should work for you as well.
good luck

I dont have fastboot in any way.
I can only power on the device with volume up + power to enter APX mode, than only my pc sees a USB device.
I tried a lot of differtent drivers but for nome of them i can ADB of Fastboot to the device.
It would help if someone that has managed to unbrick through APX mode posted the right driver for a TF300T
Cheers
have you tried the apx drivers that come with the sdk?

don't just point at the folder
manually select the driver for the device from android-sdk\extras\google\usb_driver

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
Starting Fastboot USB Download Protocol
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:
Booting Recovery Kernel image
Booting Failed
Unrecoverable bootloader error <0x00000000>. (This part is in red)
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?

Hush! @Asus_USA wanted to anounce the roll-out of Android Lollipoop for ASUS Transformers. Or was it the source code of bootloader?

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
