[Q] TF300t bricked - Stuck Boot Screen and No Fastboot - Transformer TF300T Q&A, Help & Troubleshooting

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.

[Q] Bricked Transformer

I had a working Transformer until earlier today when the OTA update came along. Having accepted installation, my device now gets to the Eee Pad / ASUS logo and hangs there (waited for about 45 minutes after the update). Trying to reboot into recovery gives:
Android WW_epad-user bootloader < e> released by "WW_epad-8.2.3.6-20110414".
Checking for android ota recovery
Booting recovery kernel image
It does not give me the Up to recovery, Down to wipe option.
Any thoughts on how I might recover the device?
Many thanks in advance for your help.
Ohh **** that dont sound good
Sorry i cant help with any advice on fixing it, apart from trying a factory reset ?
Did you apply the update with under 50% of the battery available ?
No, full. And connected to the mains.
I cant get any option to do a full wipe, it never asks me.

There are some things you can try in this thread - http://forum.xda-developers.com/showthread.php?t=1032374
Here a few key combinations for anyone interested:
VOL_DOWN + POWER (continue holding VOL_DOWN when it starts booting until you get a prompt) = Bootloader which offers two prompted options: (1) Recovery if you press VOL_UP within 5 seconds or (2) Data wipe if you press VOL_UP later. None of these seem to offer any USB devices like fastboot etc.
VOL_UP + POWER or VOL_DOWN + VOL_UP + PLUG IN USB = NVFlash mode. It clearly is the NVFlash APX device that we see appearing, but it barfs as soon as we run any sort of nvflash on it (Many Windows and Linux versions have been tried). Please note that in this mode the screen stays completely blank and the only way to get out of it is the following option:
Hold POWER for ~10s = Forced power off. This always helps if you are stuck in some weird mode and nothing on the screen
Dont know if any of these key presses will work on yours, worth a try to get it to recover ?
Yeah I had seen that thread. Unfortunately no joy from either option. I dont get the prompt when I do VOL DOWN+POWER, just seems to go straight into recovery. And as the post says, NVflash doesn't help at the moment.
Can't even seem to get the ADB USB devices to show up, I can only get the APX device which seems to be fairly useless ATM. Looks like I may have to RMA the thing.
What is that small hole next to HDMI port? Did you try that, it may just be button (use paper pin) to reset it to factory default?
Or maybe microphone ? lol i personnaly don't think those tablets would actually have a reset button, would check the manual first before sticking a paper pin into every holes...
My Transformer just came in, I accepted the OTA update and while installing it saw this thread and had a dreadful feeling. Thankfully, it rebooted fine and is working... sounds like something's wrong with yours unfortunately OP .
If you haven't tried the 10 second power button method as mentioned in an earlier post it's definitely worth a try.
stuntdouble:
I thought the 10 sec power button thing just turned the device off. Is there something else I can do that I am missing?
I think it clears cache and/or ram too. I'm not saying it will definitely fix your problem, it may not, but if it was me I'd try everything. It won't damage anything so don't worry.
Have you tried getting into the Clockwork mod recovery? You need to place it on an external microsd and when you do the holding down when switching on thing, it goes into the recovery on the card instead of the stock one. It might allow you to flash a rom to get it running again.
You can find the Clockwork recovery with instructions here
http://android.modaco.com/content/a...od-recovery-for-the-asus-eee-pad-transformer/
Good idea, unfortunately it didnt work. It doesnt appear to be allowing me to get to the point where it will read EP101_SDUPDATE.zip from the SD.
You sure filename is EP101? Shouldnt it be TF?
All the instructions call for EP101, but I tried TF too just in case!

It's a microphone. If you go poking a paperclip in there, good luck claiming under warranty.
Same thing just happened to me... reboot for update, stuck at boot screen.
Not sure if we can find a EP101_SDUPDATE.zip for higher than 20110414 if that'd be a fix or what... or even a PC restore process.

sonofab*tch same here. You would think they would warn people that this could happen. This is ridiculous. Their worthless phone tech kept traying to get me to hold f9. I wanted to reach through the phone and punch him.
So you are getting bricked units with stock? No modications or rooted devices?

[Q] Asus TF300T bricked. Black screen and APX mode only. I'm desperate!

Hello to everyone. I beg your help, please. I bought this amazing second hand tablet last friday. At the first attemp, and because I didn't want to read all the threads, I bricked the tablet. Yes, stupid thought, I know.
Because I wasn't happy with the result, I wiped all and delete bootloader, system, data... Everything. I know something with Microsoft issues and brave me (and silly) I thought It was similar, that I could start from outside of the tablet even if it was blank.
Anyway, the facts are:
The tablet is allways on, in APX mode. When I press down the power boton, it reboot. I know because when it's conected to my laptop, I can see the USB interface conected and the APX mode on it.
The screen is allways in black. ALLWAYS. No matter if I try to start in recovery in bootloader or any other way to start the system. Black, nice black.
Of course, no result in Power + Vol up, Power + Vol -, pressing power during 3 hours and 23 minutes... (I'm joking), but for long.
The only signal by which I know that it's not dead at all its when I conect the charger. I can see the small orange light in the power buton saying: "I'm alive"
Ok, I don't know what to do. I've read during the weekend as much as I could, tried evrything and nothing fixed. If it helps, before playing to be God, I had Android 4.0.1, I unlocked the bootloader with the apk, I installed the TWRP recovery and everything were right until I wanted to update the rom. Some mystakes that I don't remember and this is what I can tell you. Any holy soul which can help me, please? If not, can anyone help me? Thank you and I'll be looking forward your help.

Are you able to access fastboot? If so, flash the STOCK ASUS 4.0.1 Rom again. The mistake I think you made was flashing a ROM not compatible with the bootloader you have. You first have to update the bootloader to 4.1.1 or 4.2.1 to flash any of the current ROMS.
No fastboot, no bootloader update.

Thanks for the reply:
I can't access fastboot. The tablet does nothing, just allways on in APX, so I can't update the bootloader. Neither I can't switch it off. I've read smething about run out the battery and start a process with ODIN?
I haven't tried it before, but maybe there's a way to create a bootable SD that will automatically install one of the stock ROMs so you can start over again?
If you can't get to the bootloader/fastboot/recovery and only have APX and no back upped NVFlash files then I think you are bricked unfortunately
hi is there any solution to solve this problem, or tablet dead
I'm in the same situation! :crying:
no solution???
Same story
Same here -- black screen, PC recognizes it as an APX device, but neither fastboot nor adb seem to work.
I didn't even try to mod mine. I was just using it normally, and it crashed, and now all it does is give me a black screen. When I poke the reset button, my PC notices the device disconnection and then a minute later it re-connects, but still nothing.
Holding down volume up/down during reset does nothing. Holding down power, with or without volume buttons, for an extended period does nothing.
This looks to be like an epidemic problem for these devices. Has nobody gotten a handle on it yet?
pty
I am also in your situation.
I have a tablet with Tegra xperia 3, black screen! APX mode only!
Does not read any adb and fastboot driver!!
There are new?
Hi everyone,
for me now the same situation. Only APX aviable. no fastboot ect...
pls help me solve this issue.
Thanks a lot.
Turn on in APX-Mode. You won't see anything on the screen, the display does not turn on.
If you connect the USB cable to a Windows PC, Windows will recognize it as an APX device.
On this mode you may use nvflash tool http://forum.xda-developers.com/showthread.php?t=1969797.
If nothing works, you should exchange the Mainboard!

[Q] Eken t02/t02a equivalent stuck in boot, can't access recovery mode

Bmorn V11, Goclever A73, Eken T02, Aldi Minitab, MyAudio Tablet Series 7, ASK 748SP at the very least look the same and are probably the same tablet. So much so that I ordered a Bmorn touchscreen for my ASk tablet and it worked. ...until I factory reset it from settings a few weeks ago, since then it started freezing up ocasionally and now I get stuck at one of the 3 boot logos but I never see it boot all the way. I hope it's not hardware failing.
I found a button behind the microphone pin-hole after trying vol + and power + home and the like for hours. Can someone please tell me how I get into what i presume is called recovery mode ? I tried pushing that hidden button with the power button, but it doesn't work. Is there even a recovery mode for this device ?
Someone claims there is no recovery mode and vol + and power should work ? So what's the deal with the button behind the mic hole ? http://forum.xda-developers.com/showthread.php?t=1406429 "The device was strangely rooted when I bought it from the retailer. The instruction manual strangely says to boot into recovery mode by holding Vol + and the power button. I called the support company and they said that a recovery needs to be installed first. Using Root Explorer there is no recovery folder. (/recovery) - is there supposed to be?"
I'm on linux, do I really need windows to flash this ? If I fail, can I try again ? I used to get along computers really well, but android is currently totally confusing me. I found several images that might work, but I really don't mind trying out unofficial images. If I can try them one by one I'll figure it out eventually, but I'm afraid I might brick it or something. I've read about flashing bootable SD cards, but I guess that won't work here ? Nor will the images that are supposed to be flashed to an SD card work ?
I guess I'll have to bet on an image and find a Windows (I'm on Linux) machine and the rest is trial and error ?
Is there a page somewhere I could read to figure out the basics ? I feel really confused by all of this. Thank you !
I also found this thread: http://forum.xda-developers.com/showpost.php?p=23769918&postcount=3 which explains how to flash this, but maybe i don't need to go through that if there is a recovery mode ? And it also seems like those instructions are for t01, and it doesn't involve that hidden button at all. I guess this isn't what i need, right ?
I guess this should work:"Turn off your tablet.
You will find upgrade button located in microphone hole on the right side of your device. Press this button using e.g. paper clip. Next connect your device to your PC while
holding upgrade button" (http://www.goclever.com/data/upload..._d4d0bde076ab401d6cb98bb1b77713165b6ffb11.pdf).
I can't turn off my tablet. All I can do is force it to quit by holding the power button for 5 seconds, is that enough ?
I managed to get adb and although lsusb lists the device, I can't connect to it with adb. After a minute or two lsusb doesn't show the device anymore either. Do I need to have debugging enabled or something ? I was hoping to reset it with
Code:
adb shell
recovery --wipe_data

Indefinite Booting Stuck on Asus Logo

Hello!
After having ran Titanium Backup, I noticed a strange behaviour after booting so I went into Recovery Mode and tried to boot the recovery kernel (RCK option). Afterwards, the device's screen was frozen so I held the power button to restart the device. I tried to enter Recovery once more and chose the Wipe option. Seeing that the device's screen was still frozen, I held the power button once more and since then the device is stuck on the Asus logo.
Holding Power and Volume Down just reboots the device. Holding the Reset button (the little hole underneath the SD card slot) and Volume Up gets me in APX mode. Holding the normal power button reboots and gets be back on the Asus logo.
I have read similar threads of users having seemingly the same problem as me.
I would like to ask if there are any updates and if any solutions were found? The petition for having nvflash for Asus TF300T seemed to have been successful: androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/.
How should I proceed in repairing my tablet? Maybe the nvflash solution should work now but I lack the blob files. Anyone has them?
Thanks!

Nope. You need the ones specific to your device.
It's a bit like insurance. You need to take it out before you crash your car.
Same problem.....

Root attempt Galaxy S8+, touch screen unresponsive at TWRP

I'm going to try to keep this as simple as possible as I don't really know what I did wrong or how I ended up where I am now.
I have a Samsung Galaxy 8+ and I decided to root it. I decided to follow this guy's instructions on how to do it: youtube.com/watch?v=eh-I4uxAmUY.
I follow his steps and am bought to the "Unmodified System Partition" menu after having gone through the process of factory resetting, wiping my data and using Odin to flash twrp-3.1.0-r1_dreamlteks.
The problem is that now the touch screen is unresponsive. It does literally nothing.
I am stuck at the screen that says "Keep System Read only?" where I have to "Swipe to Unlock Modifications", but find myself unable to do so because my touch screen doesn't let me swipe!
So now I'm panicking:
Firstly, I can't get the phone to shut down. Holding the power button does nothing, even if I hold it for a full minute.
Secondly, I can't boot the phone into anything except this unresponsive TWRP thing.
Thirdly, my computer no longer recognizes my phone when I try to connect it via USB (might be unrelated?).
How ****ed am I?
Is my phone just bricked now?
Can I save this rooting attempt in any way, or at least revert to the stock?
Will bringing the phone to a retailer help me in any way, or have I already broken the warranty?
Please guys I am desperate for some assistance here.

You have voided your warranty so you can't take it down to the shop and get it replaced.
It isn't fully bricked because you can still boot into an "os" that isn't fully functional. It ain't recognised because you have to swipe past this and hop into the ADB sideload interface. Btw, try holding your home button, power button and volume up (or down) and report results.
If I was you, I would wait till the battery drains and shuts off and then let it be off for the rest of the night or something and then try again.

Alright, I'll give it until it passes out from battery loss and then get back on when things change. Thanks for the reply!
