Hi
So I have totally bricked my TF101, I basically ran the ARHD Super Wipe Full script and then stupidly hit reboot, rather than actually go an install anything.
Now my TF101 is stuck on the Asus boot screen and I can't get out of it. To top it off, my power button is totally messed up and doesn't really work anymore.
When I connect the TF101 to my computer (Win7) it tries to install the Asus MTP drivers (which fail because I get error 10, the device is not working, or something like that).
I can't get the machine into APX mode (or any other mode in that case) and I can't get ADB to work on it.
Have I totally baked the machine?
[FYI I have taken it back to Asus but for them to repair it, they say they have to change the motherboard and the cost would be HK$2,400].
Thanks in advance for any tips / suggestions.

So power button doesn't work at all?
If that's the case then I'm afraid your tablet is kinda paperweight..
Try downloading universal naked drivers and install them.. that might help in installing / recognising your tablet... I'm out of suggestions....
You can try this.. let the battery drain out.. press down volume down button and then plug your tablet into power.. as soon as screen boots up hit volume up button that should take you into recovery... once in recovery do the needful.... good luck

Did you try using compressed air on the buttons? Maybe you just have some pocket lint in there.
As a last ditch effort, you could wait for it to shut down, hold volume down, and then plug it in. If your tf boots, it will respond to the boot time commands.
APX mode might be better since you won't need any button commands once you get in. I think ASUS changes the usb ID every once in a while to keep windows users on their toes. It doesn't seem to be an issue with linux.
"As a last ditch effort, you could wait for it to shut down, hold volume down, and then plug it in. If your tf boots, it will respond to the boot time commands."
If you can do this and get into recovery you'd be closer, what recovery do you have installed? I have twrp and it supports external sd which saved me when i did this. ..
Thanks guys.
I have already tried the universal naked drivers, without luck.
I was using an old Roach recovery.
Will try the other methods. Otherwise I'm going to take it down to one of the computer centres in HK to see if these guys can do anything (and hopefully cheaper than what Asus are asking for).

has this problem already came up if so I missed it a link would be nice to fix my phone Thanks
I could be misunderstanding your problem here but I think i had a similar issue... first of all make sure you're holding down the power button long enough to boot up. Seems to take 4 or 5 seconds with this phone.
Also when I had the issue i took out the bat, put it back, plugged into a wall charger and then held the power button that worked. But I think really my issue was impatience not holding the power button the first time long enough.
no i am the screen wont say updating or whatever when i hold the up and down button but it looks for a driver ?? and installs the Right driver
helpppppppppp your way to the search button.
Thread moved to proper forum.
You only hold volume down and power. I had the same issue. Holding both volumes will cause the phone to not boot.

So you flashed the recovery before you rooted. Try reflashing the original recovery. I don't know if that will work. You should have rooted then flashed recovery.

Well your g2x will never go out of the updating screen you have to wait until one click says it has transfered the file. Wait a minute or so after that and unplug the USB and put your battery back in the I would do a master rest.

thing is my lg screen is black can i still root with a black screen ? like i said only action i get out of the g2x is if i hold the vol up And Down and plug it in then i hear the sound of the computer finding it witch gives me hope
I would try recovering recovery befor trying to root again. I would do the nvflash but pick the original recovery instead of cm. Then after that master reset by original recovery which is hold power and down volume. Recovery will rest your rom. Rooting puts you root permissions I believe into a different partition any ways that's how a master reset does not wipe them. Your problem sounds like more of a recovery issue then root.

It is problem is it stays at Waiting for Bootloader int how long should that be there?
are you holding the volume buttons down and plunging in the usb before you select the version? you have to continue holding them the whole time. should pick it up in matter of seconds.
Well I have a problem. My SNS's power button broke as if its getting pressed down all the time (powers on when i put in battery). Anyway I thought it might be a software problem so i was going to install a CM9 rom just seeing what that would do. I load up ClockworkMod via rom manager and use the search button instead of the broken power button and do a complete wipe of eveything. Once i was done and was going to install CM9 Clockworkmod said something like "search button disabled" so i couldn't select anything. Anyway I thought if I Remove the batttery and put it back in would be a good idea and then load up Clockworkmod and flash CM9.... but it wasnt. I forgot my power button is broken so i cant do anything at the Fastboot screen, I cant even use the Volume Buttons. So my next choice was use the Android SDK and hopefully flash a rom with adb. Sadly that wont work becuase my coputer will not recognise my phone at all. so im stumped on a phone stuck on either google screen or a frozen fastboot. Any ideas?

The button isnt stuck. Its broken. It still clicks when i press it down but the phone recognises it as always pressed down. And taking it apart is pretty darn complicated because I need to take the screen off aswell.
My power button is broken so I need to take my phone in to get it replaced. Following the instructions to get it unrooted/return to stock, I need my phone to be recognized in fastboot. It's not happening; I've tried it on three PC's and none of them even see a device connected. It's not even a matter of drivers because when I'm in fastboot it's like nothing is connected at all.
I can't use my volume buttons in fastboot, basicaly I can't do anything at all in fastboot...no volume buttons, no power button and it can't be recognized.
Volume buttons work when phone is turned on. I can do anything I want in recovery or when the phone is up, but in fastboot I can't do anything.
Someone please help!!
By the way, ADB works perfectly but obviously fastboot does not because my PC thinks nothing is connected when fastboot is up on my phone and as I mentioned, my phone is completely unresponsive to anything that I do when I'm in fastboot. I can't use the "volume up/volume down" and tap the power button to get into downloading mode either because MY STUPID POWER BUTTON IS BROKEN!!!
Thank you again in advance....you will be my hero if you can help me with this!!!

I have tried that so much I think I'm going to break my phone.
I just need someway to return this phone to stock without expecting fastboot to work because it seems like it is unresponsive since the power button is not working. I know this sounds weird as heck but I have all the correct drivers installed but three different computers don't see any kind of usb device connected when the phone is in fastboot. I sincerely believe it's because while in fastboot my messed up powerbutton is screwing it up because it's thinking that the power button is held down the entire time.
If anyone has any ideas on how I can get back to stock please tell me. I have 100% access on my phone when it's in recovery because I can use the buttons at the bottom and I have 100% access when it's fully booted up but when it's in fastboot I can't do anything and no computer even sees a USB device connected to it.

i believe that my phone thinks my power button is always pressed down too, but fastboot works here. my suggestion is that you try a different usb chord. i had an usb chord that i could charge with fine, but nothing else worked. i thought my nexus one was messed up until i tried another usb chord.

have you tried pdanets website? http://junefabrics.com/android/
go there, download the free download and install it to youre computer. its tethering software. but thats not why you should try it. follow the on screen instructions after its installed and itll install the proper latest drivers for your phone. theres a chance your drivers might be out of date.
oh yeah. Used pdanet drivers and Google drivers. No luck with either. I can adb with both but like I said the deicer is not the issue it's that fastboot is totally unresponsive so it looks like nothing is connected to the pc

I just got stuck in the same situation (http://forum.xda-developers.com/showpost.php?p=22884288&postcount=24) so I kept tapping the back of my phone (with the back cover off).

Mine broke when I installed Jelly Bean. Something fishy is going on. Now I have the same issue as OP.
So I have my TF101, updated to the ICS release when it came out, rooted of course.
Since then it was kind of unstable. When not using the device it would appear to power off, but pressing the power button for about 10 seconds would bring it back up.
I noticed the recovery was not available after the update, but paid it no mind for that time.
Then out of nowhere the device screen will not turn on. After long pressing the power button a click noise can be heard, it's supposed to be the camera. Since it wasn't responding, I though it was bricked.
Then connecting it to the PC will let me access all the files on the device, something very weird.
I have tried various combinations of things after a very long and tedious search, nothing seems to work.
Here are the symptoms:
-The device is turned on, but no backlight or sound.
-When long pressing the power button click sound is heard.
-When connected to the PC via usb the files on the device can be accessed.
-ADB is accessible and the device can be rebooted via it.
-After rebooting the device via the power button or ADB usb comes up almost immediately, I don't think this happens when booting normally.
So basically, is the device bricked? Why can I access files from it? How can I push a working recovery for the TF101? Is it possible to flash a ROM from ADB?
I know these are a lot of questions, but I tried, and failed. Haven't found a case like this online, and my ADB experience is limited to adb shell and reboot
Thanks in advance for the help!

The screen does not light up at all, and USB is accessible after around 4 secs of long pressing power and hearing the click noise(camera?) which is not normal since no device boots so fast. This tablet never did anyway, taking from 20 to 30 secs.
After USB is available I can adb shell from windows but that's pretty much it, I don't know what to do afterwards.

Hi Cronoadvan,
thats not bad, this means that you could use nvflash to put a new image on your TF if you want to to make sure that it is working. If you use this forum:
http://forum.xda-developers.com/showthread.php?t=1558170
then it wil be stock again, and if needed you can then send your TF back for repair.

Thank you so much! That was my last resort and sadly was clueless on how to do that too!
Hopefully it's just some kind of weird software coma, but now even if it's a hardware problem there is still hope!
Thank you very much good Sir, may life repay you thrice as much
Your welcome......please read the apx and nvflash option really well. It is rather straightforward but you have to install the apx drivers correct and use power and volume + (together) to enter apx mode. Voor drivers maybe you can use this forum below:
http://forum.xda-developers.com/showthread.php?t=1185104
it had an option for installing apx drivers for win 7 64 bit.
Hope your screen will work again, and if not you can send it back without warrant loss...
good luck!!!!!
Hey guys,
So I looked tried to charge my tablet one day, and it decided to boot loop to the Eee pad screen and continue to do that. I tried to enter recovery and it then tried to restore a backup that I had, it said there was some kind of error and CWM wouldn't work after that. I tried doing a cold reboot but nothing worked. Also I tried EasyFlash and I don't think I did that right either. I was on CM 10 before this happened with Rogue Recovery. What are the steps that I need to take in order to get my tablet up and running again.
PS: I know that there are threads about bootlooping but none of them helped much.
I would love some help...:crying:

Hi.
I have had this problem for four times after trying to flash to a custom ROM, and now my tablet is perfectly functionable.
If you used EasyFlasher to get a custom ROM and now it's bootlooping OR if you tried to root your device and its bootlooping OR if you do not know what you have to do, then check the ways below:
====================
W1:
Power up the device. When it starts bootlooping, hold both Power + Volume DOWN buttons until it will say that you should press volume up or it will enter RCK mod. When that will appear, do nothing. Just let it enter RCK mod and it should wprk. If not, then do W2.
W2:
Look under your TF101 and see if the S/N starts with B60 or under or B90. Start EasyFlasher and select the FIRST button at launch if it is B60 or under or the second if you have B90. In the EasyFlasher's folder you will see a folder with a name like "update" or "puthere". Now go to Asus' TF101 page, to downloads (Link coming soon, until then try to find it) and select the latest (first you find) firmware.Do NOT use a custom rom or you will hard brick it! Download it to the folder I said above. DO NOT EXTRACT IT. Now, make sure your tablet is at least 50% charged so it can successfully flash the stock rom. Then, connect it to your PC and press the Power + Volume UP buttons on your tablet for like 10 seconds. There must be now a NVIDIA driver in your Device Manager. Go back to EasyFlasher and press "Flash/Unbrick/Root". If anything pops up, check carefully what it says. It will probably say to be sure it is in APX mode and if you want to cpntinue. Press yes or OK. A CMD box will appear, exxtracting the firmware you put in that folder. Let the PC and the tablet do it's work. Do not use the tablet while this happens or it may really becolme unusable forever. After it extracts, another CMD box will pop up, flashing the stock fw. If EasyFlasher will say something like "system.bin - 0kb" then the update will fail and your tablet will get HARD BRICKED. In this case, PM me and I will help you. Okay. Now, your TF101's screen should turn on and say "!!!UPDATE SUCCESSFULL!!!" for like three times, and all the CMD windows from your PC should dissapear. The EasyFlasher should now stop installing the fw. Hold your tablet's power button for 5-10 seconds and release. You should now be able to start your device without bootloops. If there still are bootloops, then, do the W1.
====================
I have had alot of experience in bricked tablets, and those ways should wor. For more infos or TeamViewer help, PM me.
I hope I helped,
Kevin.

When it says to make sure that you are in APX mode, just hold Power + Vol UP buttons for 10 seconds then press ok. The drivers you have must show up as a NVIDIA driver in Device Manager when you hold that buttons. Do what I said in the previous post, it helped me four times lol.
