Broken CWM

I have flashed the CWM from TF201 by accident. Now the tablet is stuck in that CWM mode. I can't connect to usb using adb mode. Power+volume down does not work anymore. Any way I can reflash the correct CWM?
THanks

If you can boot to OS - you can use fastboot to flash any recovery.. or flash TWRP from goomanager.
upd: sry..don't see about "stuck".

I have made the same mistake. Although I can get the device to fastboot USB mode. I have tried to use CWM with the restore I made before I put in Cyanogenmod 9, as well as putting on the Cyanogenmod experimental #2 for TF300. No error messages at all and it wipes data and cash without any problems.
But I get locked on the Asus boot screen and it does not continue ie I am stuck as well.
I have as well tried to use the TWRP 2.1.5. I get the Teamwin loggo screen, it wipes all the data and verifies all the filesystems and reboots. Still stuck.
Is the device bricked ?
upd:The TF300 can not be shutoff either. When you hold the power button the screen goes black, but after ~5 s the device is starting again and is still stuck on the Asus bootup screen.

if you reboot it holding vol down and power, can you get back into the boot menu, to reselect fastboot?
if holding the power button doesn't switch it off, what happens if you leave it to run out of batteries then do this?
then you can flash the correct recovery.img

Yes, I can get access to the fastboot and I have already tried to flash with the recovery.img. I have as well let the battery run out and tried it once more with the same result.
Still stuck on the asus bootup screen.

Hare,
I have same problem.tab cannot power off. Just reboots into cwm.
I was thinking to drain bat. Thanks for sharing that info.

There are a lot of topics about people who broke their devices with TF201's recovery.
Afaik, no one recovered it. Send to Asus.

So the device is bricked then :'(.
Thanks for clearing it up.

RMA..
Guillaume,
Thanks for clarification.
I have read that ASUS wants 700USD for replacing/reflashing the bootloader. That was for the tf201. Any way to nvflash it back to factory? I don't believe that they have to change the MB.
I have no warranty left, but I don't want to be gouged by them either.
Any thoughts, info?

Hi,
I've do the same mistake, but I can use adb.
Do youhave any news about our problem?
Thanks
Midyr

unable to power off
My issue is that I have the CWM for the tf201. I did the update from the CWM app in Android. Bad idea. So now the tab does not power off s.t. I can get into the power+vol down mode. Adb does not work since I cannot ( don't know how) to make it go into the usb debugging mode. I have tried several things none of which have worked. Still stuck.
I wanted some feedback for a RMA from ASUS, posted it here but sor far no answers.

Not sure if it would really work, but on my Evo, I don't have to completely power off the phone to do the recovery sequence. I can do it during a normal reboot. There is a point just before the device starts booting again where it is technically "off", and if I hold volume down (don't even have to hold power on my Evo; volume down seems to be the only necessary button) starting at this point, the phone will boot into the bootloader.
So, next time the device reboots, just start holding volume down (possibly power also, just in case) at the "off" point.

Prerequisite troubleshooting new tablet

Hi guys, new on the forums.
I just wanted to introduce myself and say hello
Also, I just bought a TF700 for a killer price and he told me that someone (either him or someone else) tried to root the tablet and messed up. I've been told by the guy I've bought it from that it just stays at the Asus bootup logo.
Based on my reading from around the xda-dev board, the first thing I should check is see if Fastboot is installed/enabled. If so I should be in good shape and be able to restore the tablet, correct?
Overall I'm jumping into working with this tablet not knowing its condition so I'd like to know what my procedure should be to a) determine the problem and b) fix it.
Thanks guys!

Not good...So with the device is OFF. hold volume down button first, then the power button next, you only see "boot loader unlocked" ? try to hit the volume up button twice and wait a bit, what do you see?

I followed the procedure per your instrux. Still same result of "This device is unlocked" message in upper left corner. Pushed Vol up 2x, nothing. The device resets every 2 minutes or so.
That being said, I am able to boot into APX mode, however the drivers I found don't seem to be compatible with the device.

I think an issue may be that because of the fact that I'm stuck in this infinite boot loop the device never really turns off and therefore I can't get it into recovery. I think what I'm going to do is let it drain the battery and then charge it back up and try to get it into recovery mode off of a fresh power up.

Connected it to the computer, held Vol UP and power.... then i heard the conenction of usb device sound on the computer. Didn't install properly cause I don't have the drivers but in my device manager I see in other devices a device labled APX Device

Sounds like it is hard bricked to me - no fast boot and no recovery. Only known way to fix is either presaved nvflash blob files (which I doubt you have from the info above) or send it back to Asus to replace motherboard.

[Q][UNBRICK] Is my TF700 a brick OR asleep in APX MODE?

Hello everyone,
This is my first post here so forgive my errors (if any):
I have tried a few things on my TF700:
1. I have installed the rooting tool from asus website and after activating it,
The first boot scrren said (on top left corner) "the device is unlocked"
When running the app again it would give an error.
2. I tried soft reset - nothing there.
3. I went for hard reset - I accidently went for the left most icon....
After a little investigation on a few pages here I think it is in APX mode..???
It turns on but stays in the first screen with the white ASUS logo on screen & thats it...
Any ideas anyone???
How do I save my precious TF700??
I tried connecting to it through USB installing (Linux):
cat > /etc/udev/rules.d/60-nvflash.rules <<END
# nvflash support for Nvidia Tegra systems attached to USB
SUBSYSTEM=="usb", ATTR{idVendor}=="0955", ATTR{idProduct}=="7820", MODE="0660", GROUP="plugdev"

If you use the Asus unlock tool, you should not brick your device. It looks like that you wipe your system some how. I am guessing here... Can you do some test for me? If you on the Asus screen, just press the power button for about 10 seconds until it shuts down and then keep holding the power button with the volume down at the same time until you are going back to the three icons, thanks. I just want to see if you can get back to your recovery...

Than you for you reply...
I already tried that...it just loops the same shut down to ASUS LOGO screen with no response to the volume down button.
I also let it run out of power so to try & get it out of this loop which resembles an APX loop but in vain...it just keeps on powering up to the same state...
Will give it another go....
There isn't even a pause where I can slip the volume down button in, that is why I let it run out of power to slip the volume down button in...& that is what I am going to do now...let it charge for a short while and power it up with the volume down button (which did not work for several tries...)

The device will enter in APX mode only with the Volume UP + Power buttons combo and to get out of that mode you need to hold the Power button for at least 10 seconds.
If you can't get to the bootloader menu (the one with the 3 icons) anymore you are out of luck and only Asus can repair your device. APX it's useful only if you have the NvFlash backup.
Inserting a microSD with an original Asus firmware is also useless if you can't access the bootloader menu because you can't boot in recovery mode.

Make sure you do EXACTLY what sdbags said - he IS the expert.
With the tablet powered OFF, press and hold BOTH the power button and volume down button together, for at least 10 seconds. It should bring you back to the screen with the 3 icons. RCK, android robot icon, wipe. RCK gets you to recovery mode where you can use TWRP for recovery/flash installs, etc. Middle android is the cold boot option which sometimes fixes problems like you're having. Don't do wipe unless someone like sdbags explicitly tells you.
Hope you can fix this.

Well guys...thank you all for your help & time...
I tried everything anyone here suggested but unfortunately ended up with the same result: ASUS white logo screen.
The tablet is still under the first year time period...any suggestions as for how to get it fixed (RMA) without paying tones of money?
What should I say happened???
Guess RCK does not work on my device...(?)
Thank you all...

Did you try the middle android icon to see if that helped? You switch to the middle one by pressing volume down, then select it by pressing volume up.

The device also have a reset button (a tiny hole near the micro hdmi port),use a paperclip to press it and hope for the best.
As for the RMA ,Asus could charge you for repairing because you unlocked the bootloader but some users here on XDA also reported that Asus repaired their device for free even if the bootloader was unlocked.

I'm a little confused, but if I can't get access to fastboot, is it all?

[Q] TF300T Am I bricked?

I tried to root my device. I downloaded the unlocker APK, CWRecovery, adb, fastboot and everything seemed to be going fine. I ran afoul somewhere in the middle of the process and I tried to do a factory reset. And this is where things went really badly. What's happening now is that I'm stuck on the first boot screen. The only thing that is displayed in the "The Device is UnLocked" message in the top left, the ASUS logo in the middle and the NVidia Tegra log at the bottom right. No spinny and definitely not booting.
Before, when I held down the power button and the volume down button, I would get dumped in to a menu where I could select between RCK, Android and Wipe. However, now that isn't working. If I just keep holding down both buttons, the device reboots and I get the same screen. The recovery mode never seems to come up. When I try to use adb or fastboot to see the tablet, this is pretty much what comes up:
jcboget$ ./fastboot devices
jcboget$ ./adb devices
List of devices attached
So my question is this : am I bricked? If yes, my follow up question is this : can I fix this? Or am I pretty much effed?
thnx,
Christoph

Ok, so I finally got my hands on a pin to press the hard reset button and that didn't seem to have any kind of effect. All it did was cause the device to reboot and it again got stuck on the logo screen. My hopes are falling real fast.
thnx,
Christoph

Another thing, I can't even seem to power the tablet down. Pressing the power button does nothing. Holding it down for a while just causes the tablet to reboot (again, only to the ASUS logo). The only way I I'm able to get it powered down (at least, I *think* it's powered down) is by pressing the volume-up button while I press the factory reset button with a pin. Pressing the power button while holding the volume-up caused it just to reboot as it did with holding power and volume-down. Interestingly, holding volume-down and pressing the factory reset button with a pin just caused it to reboot again.
I was thinking (praying, really) that this was causing the tablet to go in to APX mode (as discussed here -- item 4 : http://forum.xda-developers.com/showthread.php?t=2034866) but holding the volume-up while plugging the usb didn't do anything so I'm not sure that's possible.
I'm hoping and praying that I'm not totally effed and I'm hoping someone can offer some input.
thnx,
Christoph

I've seen that post and I tried to do exactly that. My problem is that power+volume-down just reboots the device and power+volume-up doesn't seem to do anything. In fact, it seems like power+volume-up is the only way I can actually power down the device. How can I enter fastboot with the tablet in such a state? How can I get in to APX mode?

did you try to use the reset button to go into fastboot mode? or boot into recovery if possible and use adb reboot-bootloader?
also does your pc see the device? adb devices / Fastboot devices?

Thanks again for your reply!
Yes, I tried the reset button however it behaves just the same as pressing the power button. It just seems to restart the device. I've tried holding the volume toggle in both the up and down position (at separate times) while pressing the reset button and the behavior is the same as when pressing/holding the power button.
When I have the device hooked up to my laptop (macbook pro), neither `adb devices` nor `fastboot devices` list anything. Before my major screw up, both were able to list it.
thnx,
Christoph

After a lot of tries i got it working

Stuck on boot screen

Hello,
i am new here on forum. I read alot threads about unbrick TF300T on this forum, but cant find answer for my problem.
My tablet is unlocked, rooted and had TWRP installed. When i try to use TWRP my tablet restarted and now i am stuck on boot screen.
Its screen with asus and nvidia logo with information that device is unlocked.
When i try connect tablet to pc, pc dont see it.
Power + Volume- dont work, no boot options - tried like 50 times
Power + Volume+ dont work, i think its for APX mode
Tried restart with restart hole under volume buttons.
I cant go to other screen just that one with logo. Even cant tablet shut down. When i press and hold power button it just restart and logo screen again.
Any ideas how to make it work again, or its completly broken?
Ty for your answers.
