Help - TF300 Won't boot past Asus Screen - Transformer TF300T Q&A, Help & Troubleshooting

when I turn on my TF300 I get the splash screen that says "Asus, etc" in the middle of the screen but it turns off after 4 seconds.
I go hold power and volume and get the screen for RCK, USB, etc.. but it turns off again after 4 or 5 seconds
Any suggestions?
The SD card has been removed from the Tf300... would that stop the boot process?

Do you happen to have the link for that recover script? I have tried searching for it, but can't seem to find it. I am having the exact same problem and would like to see if it would work.

[Q] My tablet wont boot, only a black screen thats blank.

I cannot seem to get my gtab to boot anymore. I was in the middle of flashing it a week ago and I hit the power button in the middle of the process, and it shut off. I have been unable to boot it beyond a black screen since then.
I tried to put cwmod on the microsd card and hold power + volume up while booting but nothing happens.
Does anyone have any ideas on how to fix it?
Yeah - I bricked mine as well trying to get rid of the birds. Will post link to my fix shortly.

Awesome, thanks guys nvflash did the trick!
help!
I had a very similar issue but I don't see how nvflash will help. My tablet refuses to load at all after a failed rom attempt. I don't get the load screen and I definitely can't do the power + volume button reset.
Any assistance would be greatly appreciated!

Note that nvFlash is power - volume, not power + volume that's used to get into recovery mode. while using nvflash, you need to have tablet to be connected to the pc in order to run nvflash. when power - volume is pressed, screen appears to be turned off on the tablet, until you run nvflash.bat on pc to push the stock rom. Hope that helps..
The black screen after the "birds logo" or even when you power on and don't get the logo is when the tablet is stuck in APX mode. It is hard to tell the difference between tablet off and tablet on in apx mode.
The best thing to do is plug in USB to the PC and see if the tablet shows up as a device (check device manager on Windows). If there is nothing popping up in Dev. Manager then try pressing the power button again to turn it on. Even though the screen still looks off, the device should come up and you can access it with nvflash.
As others have said, using nvflash to get back to stock, or even just flashing CWM recovery will sometimes work.

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.

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.

Nexus 5 stuck in boot loop and cant access boot loader

i flashed the latest nightly of AOKP today and then restored all my apps and data with titanium backup. When the restore was complete it prompted me to reboot my device so i did. ever since then i have been unable to reboot my phone as it is stuck on the start up screen. i then tried to restore from a backup of my other rom and then found out that i couldn't boot into the boot loader as when i held down the power and + volume button the startup would begin and then the phone would turn off. any ideas on how to fix this.
What it's happening is your stuck in a boot loop.
When you are holding power and volume down the phone is only interested in the power button part. Which is why it's powering off.
Just keep the buttons held both power and volume down. When it powers off keep them held and you should come into the bootloader

Not sure if the quote is a typo or not, but it should be power and - volume. You can also try power and both volume buttons, which will take you to the secondary boot loader.

I assumed the op was able to completely power down by just continuing to hold the power button and possibly had the wrong button combo.
What do you mean by start up screen?
You see the screen tells you "Google" and it stays there?

Hi guys.
Sorry for bumping but I have the same issue and for me it wasn't fixed by going in recovery mode. I already tried deleting cash, and even tried getting back to factory settings. But still, when i restart the phone, the same loop keeps occuring.
At first it always just went to 'google' and then rebooted and rebooted. Now it just keeps stuck with the google logo (the 4 colour image).
Could someone help me possibly?
Thanks in advance

Hi Kevin,
Try LG flashtool. Link in my signature. If you have the 32GB version of the american nexus 5 (D820) you can use the converted firmware without any problem. It was tested numerous time.
You can also try to reflash stock google rom in fastboot mode http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
If you are using LG flashtool and you get error about cant format userdata and/or cache or by checking the flashing log you see timeout errors then your phone have a fauilty emmc. If you are using the fastboot method and you see "remote: flash write failure" text in the CMD window then you have fauilty emmc. Your only option is to rma your phone if bought from google or claim your warranty from LG if your phone is not from Google and you have the receipt of your phone.

So I was given a TF300T broken screen. I replaced the screen and had about 10 white dots all over the screen.
Cold restarted no love the white dots where still there and screen cal was out.
So I decided to factory restart not knowing it was rooted.
Now it's frozen at the factory restart Android with blue line below.
I have tried Vol down and pwr.................. nothing

Yup tried busters scripts... Every time I enter a command it always stays at " waiting for device" and never does anything
So I have to restart the cmd prompt to try next line or try same line again.
Is this right

Do you have access to fastboot or recovery terminal command or not?
in short no I don't think so. when it boots it.goes as follows:
A:
Press power (or power and Down)
ASUS logo appears together with Your device is unlocked (in top left)
Then goes to screen with robot and progress bar as if restoring, where it freezes after 20 sec

Ah OK. Sounds like it has a file cached that it is trying to flash. Unfortunately without fastboot we can't attempt to wipe it.
