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?
thnx,

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

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.
Hi All..
My TF300 is unlocked. I installed the new JB and then I was trying to install CWM. I used fastboot to push it to the device. When I rebooted, holding down the volume button, It came up to the menu with RCK, USB, etc. I selected wipe data by accident. It sat there for a while saying it was going to wipe and go into the boot loader. After a while I shut it off thinking it was hung. Now when I power on the device I get only the ASUS startup screen. Volume up or down don't affect the mode. It just says "The Device is Unlocked" at the top, and the static ASUS logo in the middle. When I plug in the USB to my Windows 7 computer I get nothing in the device listing. I can't even fully turn the device off. Holding power for a few seconds, it goes off, and then it comes right back on by itself.
I think I'm totally bricked, right? It won't even go into APX mode it appears.
thanks ...

When you hold down the power button to turn it off, as soon as the screen goes off, let go of the power button and hold the VOL up button. Wait a second or so and then let go of the VOL button. The tablet should go into APX mode. It can be quite hard to time it right, but the tablets screen should stay blank, without rebooting.
thanks for ur care
i forget to update the post ...sorry
.....i do that and my pc show apx driver but fastboot did not work ....
how can i use fastboot again to install bolb again ?????????

I've been searching the web for two weeks - nobody has a solution !
I've tried everthing.
Asus has a way to reset the OS as several owners have sent their unlocked "Bricked" tablets to their service center.
Last repair I read online stated that Asus returned their TF300T with the latest version of JB installed.
Asus would be Wise to post a solution - Imagine the goodwill that would generate.
Many thanks...
Q:did asus change mother board?
Or it kind of software fixed
I read about SKB..... What sbk?
After trying to flash a TBO calendar/calculator inverted app I rebooted from recovery only to now be stuck in a bootloop. The only thing the phone will do is begin to reboot itself if I press all three buttons to "hard restart". (power+vol up+vol dwn). Tried using adb/fastboot to reboot into recovery or bootloader but I don't think that the phone is far enough into the boot process to be recognized by adb/fastboot because typing adb reboot-bootloader just returns "waiting on devices". I have also tried to use power+ vol dwn combo to reboot to bootloader. I have noticed that this only works for stock and other certain ROM's. It's a hit and miss as to why this occurs.
So right now I am stuck in a perpetual bootloop with no way to get to recovery or bootloader. I don't know of any other way of getting into recovery to restore a nanroid. Any one have a good suggestion? Please!
The combination of power + volume up (for like 10 or so seconds) will force a reboot. As SOON as it reboots you just need to hold volume down to get into bootloader.

I'm having the same exact problem, I figured out the volume up + power, turns the phone back on in a hardboot. But, exactly how long do you need to hold the volume down button for once it's rebooting?? I just got a replacement phone on 9/24, my previous phone had no problem with this & had the option of fast boot in the settings. Just rebooting my phone takes FOREVER to turn on (or so it seems in comparison). Any idea how or why this is now? Is it due to an update, can I uninstall the update to go back to a fast start setting?? Thanks!!

When you hold the volume down button are you also holding the power button? You need to use volume up + power to restart. Then, when it restarts, immediately hold volume down without letting up on the power button. Needs to be volume down + power to boot into hboot. As for now long do you hold it, until it boots to hboot.
Thanks for the info...
Thanks for more details I'm pretty sure I did let up on the power button thinking it was keeping it from loading. I'll try this out now!!!
I can't get into recovery mode on my new LG G Flex 2. I've tried holding Volume Down + Power till the Logo appears, then releasing and holding again which just resets or shuts off the phone after a few more seconds, I've tried holding Volume Down + Power till Logo, then holding both Volume keys which does nothing. What does work is getting to the Hard Reset screen by holding Volume Down + Power till Logo, then releasing only Power button and holding it down again.
I've read that some things don't work on 5.1.1, but that shouldn't affect the recovery, right? As the phone isn't rooted, I can't use apps like Quick Boot either.
Help me!
I understand your frustration man, developing for this phone is a pain (to put it lightly). That being said do you have adb and fastboot installed (android SDK) on your computer? if so you should be able to open a command prompt and type
"adb reboot recovery" without the quote... and hit enter, and it should reboot into recovery. I cant guarantee you wont see an android laying down with a (!) in a triangle.... If that happens unplug your phone and keep pushing and holding different button combos to get it to reboot regularly again

I'll try that, thank you. But is there an explanation for why the normal way - using the hardware buttons - doesn't work? What could be wrong?

In may case works in the same way. With the button "combo" doesn't work. If you have root can get an app from store to do wipe, like system tuner.
I have searched and looked for alternatives on how to maybe enter download mode but have not found any solution. I have tried phone off then vol. down + bixby then plug in usb, also pow button + bixby + vol. down then plug usb but every time I do this all I get is a circle with a lightning logo with battery percentage. I also went into recovery mode and tried rebooting into bootloader however that just ends up rebooting back to the recovery menu. Please help. Thank you.
anyone with any tip on what might help or be the issue? I have an exynos version.

Hi, try to reboot into bootloader using ADB.
First off thank you for the response.
I tried that as well however maybe I did it wrong. Is it? adb reboot bootloader or adb reboot download
It's so strange you know cause I've tried so many different ways and I thought that rebooting to bootloader from recovery menu would definitely work however all it does is reboot back to my home screen.
Power off phone and just hold down pwr+vol up+ Bigsby for like 8ish seconds and it should boot to download.
Also adb/fastboot is a second route, read through this the below link. Make sure you have the Samsung drivers installed and adb/fastboot properly installed and prerequisites. https://www.theandroidsoul.com/unlock-bootloader-via-fastboot-android/
Or try to boot in safe mode
Hold power button when phone is on, then long press power off, and then select safe mode. https://www.verizonwireless.com/support/knowledge-base-223011/

well apparently I can't boot into safe mode either, while screen on I long pressed power button then long pressed power of for more then 10 secs but that doesn't do anything
crazy thing is I'm able to boot into recovery with no problem but that's about it. also adb does recognize my device as I can see the characters after inputting "adb devices"
