stuck on asus boot logo, recovery stuck on booting bootlaoder kernal image

i'm a damn tool and i'm hoping one exists to get my tf300t tablet running again
i had it running beautifully with cm10, then i decided i'm gonna install the touch clockworkmod, but i didn't read the thread properly it was for a stock jb rom, so now when i press the power button, i'm stuck on the asus boot logo with " this device is unlocked" text in the upper left corner, and when i push power + vol down it locks up at " booting bootloader recovery image" , i'm wondering if there is anything i can do to save my tablet or is it bricked and there's absolutely no way of fixing it, thanks for your time

Can't you just install the non jb recovery?

thanks for your reply, i'm not really familiar with twrp, can you go a little more into detail as to how i need to use twrp, do i run it from windows or from the tablet, on my tablet i'm not able to access any type of recovery, it locks up as it's trying to boot bootloader kernel image, thanks so much for your help!

how do i go about installing the non jb recovery? i can't access any type of recovery on the table to flash one, thanks

well i just found out by holding vol up and the pinhole reset button then 3 seconds release the reset button while still holding vol up, i can get my computer to detect apx mode
hopefully whith a NVflash version for the tf300t we can recover it

[SOLVED] Bricked my Transformer....

Hi all,
I had my Transformer up and running on CM10 when I decided to give Asus JB a try this morning. As a preparation I tried to switch from TWRP to CWM. So I followed the instructions here using dd in a terminal on my tablet. After this I tried rebooting into recovery (Power + VolDown).
But I didn't work, it took me directly to a message saying "OS will cold boot in 10 Seconds if the selected mode is not confirmed". I had the choice between wiping and fastboot.
So I went into fastboot and tried to reinstall TWRP using fastboot. This worked withoud errors but after a reboot to recovery I got the same problem. When I choosed wipe date the splash screen from TWRP came up for a few seconds and then it disappeared and I shows me some lines telling me that it wiped my data - and then the device reboots.
A normal reboot led me to a screeen showing the ASUS Logo and the "The device is UnLocked" in the upper left corner. And nothing more happens...
So tried to reinstall CWM using fastpath which also worked without problems. After reboot still no direct access to CWM, had to go through wipe-data again and then it jumped into CWM. I installed several different Images with CWM but none of them solved that problem. The device still istn't able to boot into OS or direct into CWM.
I also tried to flash the blob file from stock firmware using fastboot, but after the transfer ended and it startet to flash it stopped with an red line saying an error occured.
Now I'm running out of ideas how to solve this problem. Any ideas?

If you have working fastboot maybe i can help you,what's your bootloader version?

I'm not sure, is there a way to see the version?

Connect your tab to your PC
Open a command windows on your PC
Goto your fastboot directory
type fastboot devices
you will see bootloader version

ok,let me put it this way,did you ever upgraded to 9.4.5.30 firmware?

No, not before my tablet got bricked. I tried to recover with a stock Rom afterwards and accidentally downloaded and flashed .30 instead of .26
Maybe this makes things worse but the problem is not caused by that.
Btw: thank your for your support

Did you used NvFlash tool while you were on .26?Anyway you should come here on irc --> http://webchat.freenode.net/?channels=asus-transformer <--- it's easier to chat than here on forum.

No, I stupid idiot did not make a backup with nvflash.
I really appreciate your support but unfortunately I'm not at home anymore so I can't chat for the next hours.

Have you try this :
Code:
*** Factory Restore after a softbrick/Downgrade from Jelly Bean to ICS/Clean Factory Restore ***
When You Need This?
* if you get stuck on Asus boot screen (the one with the spinning wheel)
* If you don't like JB and you want ICS back
* if you want to get back to a clean stock firmware
Note: You need to have a working recovery (stock or custom) in order to use this method.
========= Recover /Downgrade from Jelly Bean to ICS/Clean Factory Restore with stock recovery =========
1) Download the latest firmware from Asus site (based os your SKU,eg. ww 9.4.5.26 * to downgrade from Jelly Bean you need the 9.4.5.30 firmware)
2) Extract the .zip file somewere on your desktop (the result will be another .zip file,use it for step 3)
3) Rename the extracted archive to "EP201_768_SDUPDATE" (without the " ") and upload it to a MicroSD card
4) Insert the MicroSD card in your tablet and use this button combination to Power ON and go to recovery --> Start the tablet by pressing Volume Down and POWER togheter for 5 seconds ,a message will inform you that you have 5 seconds to enter the recovery,press Volume UP before the 5 seconds expire.
At this point the device will go in recovery and should start updating your firmware .

Yes. I tried this but it does not work. When I start with pressing Power and VolumeDown the system only lets me choose between wipe data and fastboot mode. It does not recognize any system update files

Problem solved...
Hi,
just to let you know I solved my problem. After trying a lot of different possible solutions described in a lot of threads nothing worked for me. Finally I flashed JellyBean through CWM from external SD Card. This did not change anything but after booting into fastboot mode I installed the kernel blob extracted from a zip file found here by using
Code:
fastboot -i 0x0b05 flash boot blob
And that's it.... after 10 hours of try and error I finally got my device up and running again....

For #5, do we select RCK or something else? When I select RCK and push vol+ twice, I just get the bootloader issue 0x00000000.

when u select RCK does the green Light glow keep on Blinking or not?
Are you using unlocked boot loader??

When I select RCK the blinking stops.
My tablet says in the upper left corner that my device is unlocked.

What problem exactly are you facing?? Can you boot into android??
Do u have CWM recovery or TWRP??
Did u follow all steps?? r u using the same SKU as u r tablet??

The problem I am facing is that I do not have a recovery working. I cannot access recovery at all. I was trying to update the tablet by downloading the official firmware and placing it on the root of the sdcard. But it wont recognize the update when in Android. (I can boot into Android.)

HI
I think then try to re flash your recovery first using fast bot method...then try this guide again..
or the last option is send to ASUS..:silly::silly::silly:

Is this method work with every firmware, and is it work on me301t?

After Update 7-29-13
Similar problem 300t does'nt go past the asus startup screen, when i tried to do a wipe and restore it just goes back to the asus load screen (with spinning circle)and sits and spins, so then I tried reinstalling from micro sd card using the trick where u rename the file to EP201 after trying to reinstall the newest version and an earlier version from the microsd and got the dead android (same results for both )and when I use recovery I get the android guy and loading bar and he fall over dead with error, but when turning it back on, everything goes back to the stuck loading screen. If you connect the tablet to a pc it says usb driver install failed and if you try to force driver install through device manager, the driver install completes but then says the device cannot start. asus sync does not see it , I want to try to put the ep201 file in the SDCARD folder in the internal sdcard but cannot perform this because the pc cannot see the tablet. any help or suggestions would be appreciated.The un rooted tablet Was running 4.2 just fine before i tried the new ota update 7-29-2013 and thats when this happened , I tried to call Asus, since my warrenty had expired last month they said they would fix it , but it would cost me .....i explained that their update is what made it unusable, but they didnt say anything about that fact. and told me the same .... if you have a idea or have solved the same issue PLEASE post
Thanks

[Q] Soft Bricked Tf300TL locked bootloader

The Title pretty much spells it out I soft bricked my TF300TL. The tablet still has a locked boot loader so I am not gettting any recognition from my computer using adb shell. Is there anyway to re-install (already have the rom) stock.
Thank You!

TF300 Bootloop

Greetings guys,
I'm quite new here. I just received my asus tf300 from my brother as he dont want to use it anymore. The sad thing is my tf300 is bootlooping. I don't what happen but one day it is suddenly bootlooping at the ASUS white logo. I try to re-flash the stock ROM but fail. During the bootloader, it said something like this
"Android cardhu-user bootloader ＜1.00 e＞ released by "US_epad-10.6.1.15.3-20130416" A03 Key Driver not found.. Booting OS
I dont know what does that mean. My tablet will bootloop and I can't shut down the tablet as I need to wait until the battery dried off. I try to re-flash using the technique in master guide help ([GUIDE] How to manually update/restore firmware (Tf700, TF300, TF101, possibly TF201))
but it won't work. I try few firmwares but i still does the same thing. I dont know how to use the fast boot as there is no USB icon in my bootloader. So I dont know what to do. And of course my tablet has no warranty anymore.
Any suggestion? Btw, my device is locked, not installed recovery cwm or twrp. so I dont know what to do. I searched everywhere to fix my device by cant get it done

Hello ,
go to the Recovery and wipe cache and dalvik cache. And after that normally reboot and then it must work.
Fastboot will be start when you go to the recovery . The old USB Icon for Fastboot was removed by Asus by the update to 4.2 Jelly Bean.
Press Power button and volume Down for 10 sec to come in recovery. After that select rck and make the wipe cache and dalvik !
