Hi all,
I have an ASUS TF300T.
A friend of mine tried to root it and install a new rom. He said he followed steps that he found on XDA and was trying to flash a new JB rom.
Having said that, now the tablet is stuck at the ASUS Logo during boot and there is a message on the top left "the Device is UnLocked"
Nothing happens!!
I tried holding POWER + Low Volume button and it does not get into bootloader. ADB and Fastboot does not detect the device. Even Windows and Linux do not detect the device.
So i tried POWER + increse Volume button and it gets into APX mode. I used the Universal Naked Drivers on this site and windows detects the device.
But the question is how do i restore it or how to reformat it ...etc.
Is there a way to use External SD card to get help in this situation.
Can anything be done from the APX Interface ?
These are the links that my friend has followed ...

Hi,
Sorry for my English, i'm French...
I just pick a nice Asus TF300T Tablet (WiFi version) never used.
Being an Android user (HTC Desire) for a long time, I wanted to go into the root Cyanogen.
To unlock it to work, since displays "The device is unlocked" at the top left on boot, but the Recovery blocked the machine ...
Indeed, it is now blocked non-stop on the logo "ASUS". At this point, the battery is not removable, I do not know what to do ...
I tried to do the command "adb reboot recovery", but the tablet is no longer recognized on the PC (Windows).
I of course tried rebooting still pressing "Volume down" "Power," but that does not change.
HELP NEEDED ...
It's a shame, it's a beautiful machine ...
I can only make it recognize APX mode by the PC. ("Volume +").
Windows drivers so as to recognize the "Asus Transformer Prime APX Interface".
But once, as no command or control FastBoot ADB does not recognize the tablet, I do not know what to do.
- I just tried to put the firmware "WW_epaduser_10_4_2_20_UpdateLauncher.zip" Asus recovered from the site on a FAT32 formatted MicroSD: Nothing.
- I tried to rename the firmware 'EP201_768_SDUPDATE.zip "Nothing.
I tried the nvflash, but APX for TF300, this is not working ...
An idea??
Even though the TF300T is similar to the 700 you may get better help on the TF300T section here >>> http://forum.xda-developers.com/forumdisplay.php?f=1578
There's a brick discussion going on there now >>> http://forum.xda-developers.com/showthread.php?t=2131643
Good luck my friend!
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?
Do you have an sdcard for this tablet?

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!

After a lot of reading on Xda and Modaco I am still not much further.
After rooting with Framaroot and installing TWRP through Goomanager I bricked my phone because I forgot to unlock the bootloader....
Is there any hope for this phone?
The phone cannot get into fastboot: power button + volume up.
Recovery menu (power button + volume down) is non-functional > I get the "invalid kernel" message again.
ADB and Fastboot and cmd in Windows are all very new to me but I have nothing to loose.
Thanks in advance for any advice.
"invalid kernel !!!" - I bricked my phone
Hello,
I have exactly the same problem... I've also red a lot without finding any suitable solution...
I rooted with Framaroot, installed TWRP and thats it - I bricked my phone (probably because I forgot to unlock the bootloader?)....
Same problem for me: the phone won't get into fastboot (Power+VolUp).
Recovery menu (Power+VolDown) doesn't work: I always get "invalid kernel !!!"
Hi Vakilando,
It seems we're on our own with this problem. Either no one has an answer or all knowledgeable people never had to deal with this problem.
We also choose a not-so-popular phone. The tablet-phone combi is too expensive and the tablet of mediocre specs.
I went for the too-good-to-be-true price for the phone-only... and after a lot of reading found out that quit a few people had problems with their phone.
Perhaps some code monkey (no disrespect) could tell me if we have more options when the phone is connected to a Linux system? Android is Linux based, so that would be a compatible pair. Windows can only see one partion on a flash card and, but I might be wrong, Windows cannot read EXT 3, 4 partitions.
Windows device manager does recognize the phone as "ASUS Android Bootloader Interface" so the phone is not completely non-responsive.
I also posted on a German site; Android-Hilfe where there's a dedicated forum with knowledgeable people so perhaps that gives more options.
do this!it will work!!!

Sorry, for not well-advanced users - could you please describe step-by step how to flash phone in "invalid kernel" condition CWM recovery with fastboot? Tnanks!
Ola Goldenval, try this link, it worked for me.
This is first link I found in google & tried to follow. My problem is that PC (W7 ultimate) doesn't see the phone. So cmd window is hanging on message "waiting for device" forever. Problem isn't in PC, as I tried different PC, where another similar phone had been seen some time ago.
Hi Goldenval,
the onlything I can tell you is that it didn't work out for me the first time, just like you now. Then I found another, German, website with lots of information on the subject and I gave it another try. Second time I succeeded...
it is a long time since it happened so I can't recall all the details but keep on trying and you will succed.

Hi
I can't remember how but i bricked my tf300t.
Now it's stuck on ASUS (and on top it shows device unlocked i rooted it before and it worked.) screen nothing is responding.
The only thing i managed to do is when i click the rest button with a pin under the sd slot and hold the volume up button i manage to get usb reaction.
i tried several guided here. With installing ADB / Fastboot drivers. I see it on the device manager but ADB/Fastboot showing me that it's waiting for a device or no device found.
I really don't have a lot of knowledge troubleshooting it by my self so i'll be happy to be guided step by step to help me.
Thank's

Thank you..

hmm.. no one can't help me to solve this...
Hello roomraditz, right now this issue doesn't have any easy solution if you are entering on the APX mode means that the firmware has been corrupted anyhow and in order to install anything in this mode you would need to recover some keys that are not available at this moment.
I have been working on find these keys but I didn't have any result yet.
