First let me say that I have been using google to look through this site for similar problems...as well as many other sites...but all the android forums use formats I'm not familiar with. I'm still learning about the site layouts and am searching and accept that this may be a common problem...if so, please forgive me asking.
I've got debugging mode turned on.
The tablet has been rooted.
I have the KatKiss 4.4.4 and gaps loaded on an SD card in the tablet.
When I go to try and get into recovery mode (power on + volume down, volume up within 5 seconds of boot) I get a loading screen and then what I describe as a dead android with an exclamation point above it.
If I hold the volume up button on boot the options I'm given are cold boot and a data wipe.
Is there something special that I'm missing to get the TF101 into recovery mode so I can update it 4.4.4 or later?

Ok so i've looked, cant find anything to help me out here... Its always possible i used the wrong search terms but i think i did pretty good...
Anyway, i had flashed i believe a CWM version of ICS when it first came out because it was easy to do, and i was able to keep root. Well I ended up with the CWM Recovery version that had the problem of constantly booting into CWM, so i fixed that and the tablet was telling me there was a firmware update, so i did it..
Now im stuck at the splash screen... When i try to boot into Recovery, it says its loading the recovery image but never does anything else. When i tried to load the other screen where you can choose recovery or the OS, i think people call it the linux screen? I dont remember, but when i did that, the big battery meter displayed on the phone for a second then disappeared... Wont turn on now, so i just plugged it in.. Is there something im missing? Or something i can do that anyone is aware of?
Check if the Android Debug Bridge works, and is your device a B60 or lower, (sbkv1)? If so you can use NvFlash to restore the tab.

Last time i tried to boot, i tried Power+Volume Up and i saw the large battery that android phones typically show when they are powered off and you plug it in.. If i remember right, TF101 typically boots up if you plug it in when turned on, but it turned on, flashed that battery image and shut off, havent been able to turn it on since... Plugging it into my computer though, it wont turn on, plugging it into the wall outlet it turns on and sticks at the splash screen, so i'm gonna leave it there for a bit and see if it charges, then i'll try plugging it into the comp to see if ADB works... I'll let you know, thanks!
To get to recovery its power +vol down. Power + vol up gets you to apex mode, blank screen.

.....don't know if I read all your info correct but to enter recovery is volume down + power until you get a message at the top of the screen then you let go both and press volume up to enter recovery or if you don't hit volume up it takes you to the cold boot / wipe data screen.
Yes, i posted that... I tried booting to recovery and it freezes when it says its loading the recovery image.
I was trying other combinations trying to remember the linux screen or whatever it was called, but either way. ADB mode doesnt work, im stuck at the splash screen.
SOLUTION: Do not do the update after fixing your TF101 if you have this same problem, because you'll have it again! Either way, here's what you do.
1) Since you cant shut off the TF101, hold the power button until the screen goes blank, then immediately let go of the power button and hold volume down. 2) The splash screen will re-appear, dont let go of the Volume Down button until you see the text at the top left corner of the screen prompting you to press volume up to enter recovery.
2) Dont press Volume Up since it will freeze trying to get into recovery. Instead, just wait and make sure your not holding down or pressing any buttons.
3) After a few second, you will be presented with two icons, one to wipe data and one to boot android/linux, selecting android/linux WILL work and boot, but you'll have the same issue as before without fixing anything if you reboot again. Follow the instructions to wipe your data. YOU WILL LOSE EVERYTHING!
4) At this point, Recovery still wont work. Boot your TF101 and get it setup and use the Play Store to download a terminal emulator
5) Open the terminal emulator and type SU and press enter, confirm superuser access.
6) Type in the following and press enter when done: echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
7) Restart your transformer, let it boot normally the first time, after that, recovery should work.
8) Problem solved, DONT install the update this time! Install a custom ROM the typical way using CWM, and your set!
So, one thing i've noticed is im being spammed out of my mind from the OS to do that system update, so i've found that the best thing to do once your bootable, is to flash a custom ROM.
I tried this but went back to the same ICS version I had before, and ran into the same problems. Ended up with a whole other ROM, and now all problems are solved!
Good luck to anyone that has this issue!

so you lost all data, all apps, all settings, all the effort and work and time to config apps and settings... UGH
I am in the same boat on my TF201 after the JB update bricked my tablet... really pisses me off as Asus says RMA it (which you know they will just wipe your data) or wipe the data yourself and hop it works. So badly want to salvage my app settings and all the work I did to trick out my tablet. F***** Asus, their own update fried my tablet.
First,
I really want to thank everyone for their support in this forum. Everyone has been amazing.
I was trying to bring my MZ601 back to stock yesterday. Something bad happened during fastboot and asked me if I wanted to unlock my device. Then the screen locked up and didnt do anything. I rebooted the device and now it gets stuck in a boot loop with the EOS symbol (last rom I installed). When I enter recovery there is nothing there, all of my data is gone.
Worse the device is not recognized on my computer nor can it be found in adb fastboot. I have updated motorola drivers, but I think the device never gets past a certain point in order to be found.
Can somebody please help me.
Thanks,
Pretty impossible to brick XOOM's but i'll ask the basics. Can you get into recovery from a cold boot? Can you get into fastboot from a cold boot?
By the sounds of it you've just corrupted your rom or tried to re-unlock the device which would cause the entire sdcard partition to be erased.
Boot XOOM into Recovery, Fastboot, or RSD mode
So you need to get into Recovery to backup your XOOM (you do nandroid don't you?). Or perhaps you were working on creating new levels of awesome and something happend and you find yourself staring at the Motorola Dual Core boot screen with your XOOM refusing to boot any further. Fear not, you are only a few clicks away from finding your way back into recovery or fastboot goodness.
Turn your XOOM off
Press Power to turn your XOOM back on
When the Motorola Dual Core boot screen appears tap Volume Down repeatedly until "Android Recovery" is displayed
Press Volume Up to enter Recovery
You can also choose from Fastboot protocol support and RSD mode by using the same method but instead selecting their respective menu prompts.
Note:
If your XOOM is caught in bootloops or you find yourself stuck in RSD mode or Fastboot Protocol support you can hardware reboot your XOOM by pressing and holding Volume Up + Power until the tablet reboots (usually a few seconds but could be longer).

Hi,
Thanks for the tips. Unfortunately, it seems that I have caused the entire sd card partition to be erased. That mean when I trry to fastboot my device is not recognized. Also, i cannot add anything to my xoom through usb. I have tried to flash through the external sd card, but to no avail. What do I have to do?
What does your xoom show up as when plugged into your pc APX? Can you boot into fastboot mode. with power off press power and volume down until you see fastboot.

Hi thanks for the reply to my message.
Unfortunately I cannot find my device when it is plugged into my computer (PC). It does not show up on my computer nor in the device manager. I can start the fastboot protocol on my device by rebooting, but I also cannot find my device in ADB.
Thanks for the reply, but I am still very stuck.
are you sure your device is in fastboot ? did you reinstall the drivers, try with another usb cable, adb shoud see the device after the drivers were installed correctly ...

I did everything I have done before. I have setup android sdk, java, and motorola drivers on two different PCs. Both fail to find my device when i type ADB devices nor does ADB reboot bootloader work. I tried the different cable, but that also did not work.
Hi,
I see that your problem is quite hard, try doing this:
1 - Force your tablet to shut down (vol+ + Power)
2 - Turn on while holding the vol- button
3 - Keep pressing vol-
4 - Plug on your PC and try fastboot devices, adb won't work!
5 - If 4 didn't work, keep trying until it does
6 - Install a Stock ROM (so you will solve your problems)
If the above don't work, contact me via PM, so we can talk easily (maybe GTalk or something like this). Good Luck

XxLordxX thank you!!!
I took your advice and just used fastboot. Then I flashed the stock rom I wanted to use. My xoom is back up and running. I really appreciate the tip.
Also thank you to everyone that responded in the post, again, that is why I love coming here.

I have this problem now but I don't know what to do. Please help me out
Yesterday morning I met with the unfortunate tragedy that was my tablet becoming a brick. I was trying to explore flashing and installing Kit Kat on it as it seemed a good idea to bring new life into the machine. The problem started with the recovery mode for flashing a rom on the tablet always froze. Whether I was in the menu with RCK or doing it within an app, I could not start any recovery menu. Eventually, I after getting a little frusterated with the problems, I accidently clicked wipe on the power hold volume - menu. Now my tablet will not turn off and sits at the ASUS/NVidia logo screen and has "The Device is Unlocked" on the top right. I unlocked and rooted it months ago.
I cannot get into the recovery or get fastboot to recognize the device at all. Pressing power/volume down does nothing anymore. I did try pressing the tiny hole for the reset button plus the volume + and the USB reacted on my Win 7 PC and I installed ADB drivers for it, but I can't do anything with it and my tablet is a blank screen when it happens. I suppose because it is wiped there is no OS on the system? I simply refuse to believe it is beyond repairing due to these factors.
I am very desperate for help and I have been scouring the internet for an entire day to no avail. I have even seen a few people with the same situation on this board, but the question was never successfully answered each time. Lets try working together to create the definitive answer thread! Forgive me if I am not stating the terminology correctly as I am new to this. Thanks in advance everyone.

I am in exactly the same situation. No fastboot, volume up with reset gets me to a blank screen state which windows recognizes as an unknown device. I downloaded the Asus drivers but it's still not recognized. I may need to go back through the forums to find a way to push a working Recovery of TWRP. Currently I am out of ideas.

So far the only known recovery to that situation is using Nvflash and APX mode. However, you must have already made Nvflash Backups before pressing the wipe data. If you did, there is a link in my signature to restore you tablet.
Hi!
I've read many threads and I haven't found the answer I'm looking for.
I've flashed the 5.1 update via TWRP on my tablet, and in the first boot it rapidly installed something, rebooted and never worked again. I can't use adb fastboot because my pc doesn't recognize my tablet. It shows as APX. I've tried to install the APX drivers and I can't, even after I reboot into advance settings.
Have I not read the correct post? Please help get my tablet back. I know it was stupid of me not to disable wifi before deleting the TegraOTA, I was in a hurry and forgot. Is there any hope?
Thanks for your patience.
Sounds like it took the forced update to kill it. If you can't get into the bootloader to use fastboot I don't think you'll be able to do much.
I might have done the same thing as you. If you do vol down+power does that still start up? if so this worked for me
https://forum.xda-developers.com/shield-tablet/help/help-stuck-nvidia-boot-screen-t3076462
I'm stuck now I'm on the stock rom and dont want to connect to wifi and get a killswitch, but I can't get a custom recover to load to change roms
Edit: When on the laying down android with "no command" if you hit the power+volup+voldown it will go into recovery settings. I guess the custom recovery isn't really flashing over.
Unplug USB cable press power for 30 seconds and then press the power and vol down should go to bootloader if your tablet didn't get kill switched. If it still doesn't boot and shows apx once connected then its been kill switched. Pressing power and vol up will place it into apx mode by default.

Hello Sirs,
in the attempt to test the ART runtime I'm now in the situation where my TF101G rebooted and went into an infinite booting showing the Katkiss animation...
Cannot enter APX mode as the volume up + power doesn't work.
ADB is showing the tablet as offline and of course I'm unable to put on the USB debugging...
Cannot enter in a recovery mode.
Can only do Volume down + power but I'm unable to choose the wipe and the tablet goes into an apparently safe boot since as a matter of fact it boot as usual (infinite boot).
I've tried to leave it for 24 hours on but nothing changes.
I'd like at least to recover all my files stored in the tablet....... Does anybody know whether any chance to do it? Is there any JTAG or anything else which might help?
Many thanks in advance your suggestions.
Regards / Lungo72
