I have a TF101 that's seemingly dead after being dropped. Currently, it does not power on. When plugged in with the ac charger, it shows no sign of charging, i.e., no light of any kind - amber, green or otherwise. I assume the mainboard has gone south.
When I connect it to my laptop, however, Windows 7 gives a chime and recognizes it as an MTP device, and even lists it as a TF101 in device manager. Linux also acknowledges that much. I can pretty much browse and access the content of the internal SD card like an external HD. Holding the power button long enough will unmount the device in either OS, which suggests that the device has turned itself off, and thus still responding to physical commands, or functioning on some level.
So it appears dead but not really. Being totally unfamiliar with this model, I'm not sure what possibilities the current state of affairs might indicate insofar as the device's vitality. Any input as to what this means is greatly appreciated.
If is it determined that the mainboard is done for, can anyone point me to a source for a replacement? If this kind of info solicitation is proscribed by regulation, my apology. Thank you.
My guess is, if the board was dead, you wouldn't be able to mount the device at all. It would suggest that it's actually alive and well, but the graphic/monitor part is dead, so you have no display at all. Mine also shows no signs of life (assuming I don't check the display) while it's charging and not on the dock. Only the dock has charging status lights as far as I can tell.
Sadly I can't help you further than that. I know they sell replacement parts on ebay and such, but I never even opened mine up, so I have no idea how easy it would be to replace any part. I know there's repair videos on youtube for the tf101, it might give you a clue if you open it up and run some tests.

On second thought, I'm not too keen on replacing the MB just yet. Cracking the thing open is no big deal. I am dexterous enough. However, I am more intrigued by what is possibly going on.
If you guessed right, and transferring PC knowledge to this, the board would have a video chip integrated, with the other part consisting of an inverter and the LCD. If the integrated video circuit is dead, then connecting the device via HDMI to a TV would show nothing. If the device shows up, for instance, it's just the display part from the inverter on and so forth.
But I'm hesitant to go down that route. If it's the video part, then I should be able to do everything else like putting it in APX Mode, or flashing as with a normal device. Unfortunately, my computer never registered such activities; the tablet does not respond beyond the symptoms I described above.
As a matter of fact, I'd entertain any mad proposal on what should be tried on the thing at this point, just for the fun of it. I stand to lose little. So you can use your imagination and shoot some crazy ideas my way, and we'll see what.
So you tried with HDMI and it didn't work? You're right about APX though unless you're missing the drivers.. so maybe there really is some damage to the board. Sadly I don't have any crazy/mad suggestions at this point
My normal approach to possums (and the only legal thing I can do with them once captured) is to kill them or get someone else to kill them for me. :good:
As for your TF101, I seem to remember reading on another forum that when these devices are dropped and show the symptoms you describe, it can be caused by a ribbon cable that connects the display to the motherboard being jolted loose. It might be worth opening it up and check both ends of the appropriate cable for secure fit.

Hey I totally agree that killing it may be the only option right now. And I don't mind that, just that I'd prefer the scalpel to the cleaver, and doing it in such a way that I would learn something about it that may be of benefit to me and incidentally, to others. I did open the thing, and you're again right, people have run into this problem of the LCD cable being jarred loose on impact from Asia to the Western Hemisphere to Eastern Europe. But it's not that, as I did unseat and reseat the cable on both ends, for naught.
As to the APX drivers, I did try both Easy Flasher and PERI 0.4. They act as if they finish the job. However, the tablet remains consistently inert. Lethe6, am I missing something here? How do you tell if the APX drivers are missing? Normally Windows would show the USB device as in APX mode right? Mine did not do that. When I tried to update the driver in Device Manager, Windows refused to do it claiming it was not necessary. Is there a way to force-install the drivers just to see?
Oh well, I'd just let the issue hang at this point and see what else comes this way.
Yeah if you connect your device in APX mode it should pop up in the device manager, just right-click uninstall then re-install the drivers. I don't remember what's the exact device name but iirc it's something generic. Sorry I can't check I'm on a Mac at work and my TF101 is at home.
What about HDMI? Did you ever get a signal through there? Tried having it connected when assuming to do a full boot?

I never had the chance to try the HDMI output. Still waiting for the adapter to arrive. Ebay can be a pain during holiday season. But I'd sure to report the result. When I plugged the thing in, Win recognized it as an MTP device and proceeded to install drivers automatically. After which it showed in Device Manager as TF-101. So apparently the drivers are correct, though they dated back to 2006!!?? However, with other devices like the Acer A500, the USB device symbol normally would appear at the right bottom bar with the designation "APX device." With this thing, nothing - not even the icon. What's your thought on this?
I don't have any other devices that I can boot into APX (HTC won't tell anyone and my other tablet is a craplet, have to ADB on the live FS, which is awesome lol) so I can't compare here, but have you tried these drivers for APX? It's been a while but I seem to remember needing special drivers for APX. The device had a weird name.. like a bunch of numbers and letters... haven't used it since easyflasher though.
When I plug it in APX the device is called "NVIDIA USB Boot-recovery driver for mobile devices" and it's dated 1/31/2011.
When I plug it in Rogue Recovery the device is called "Asus Android MTP Device" dated 7/17/2012.
When I plug it in booted to 4.0.3 the device is called "Transformer TF101" dated 7/17/2012.
So I'm guessing yours never enters APX or has the wrong drivers? Maybe try installing the ASUS Sync software? Not sure but it may bring newer drivers...
I assume you're doing all this undocked as well?
I have read every single thread that exists on the internet about this problem, the bootloops, the faulty bootloaders, the wrong rooting and image installations, every single posible way to brick this piece of device that everyone seems to have problems with. Yet none of them has gave me a solution. First of all, it's my girlfrinds tablet, she told me that one day, she tried to upgrade the android software and while it was installing it, the tablet bricked. She was able to go to fastload mode (power + volume up) we've tried recovery mode, factory reset, every option there, nothing. She gave me the tablet, I plugged it on my pc and used Nexus Root Kit to install a new android software to the device. After a painful search of how to make the Kit recognize the tablet because usb debugging was not on, I was able to start the process of installing the new software. Yet, in the middle of the installation, the micro-usb moved a little bit and the tablet got disconected. The process was cancelled and the tablet screen froze. I turned the tablet off and that was when it just bricked and never wanted to turn back on. Neither with any combination of the buttons, nor while leaving it charging a long time, nor any possible solution the internet may have about this. Just fully totally and simply bricked. Yet, when I connect it to my pc (windows 7 ultimate 64 bits) sometimes, it reads it as an unknown device, sometimes it reads it as a random APX device, and when I install any kind of drivers that already exist on every thread that there is about it, it reads it as an ASUS Transforme Prime APX Interface, yet the tablet never displays anything, and I'm not able to access it in any way nor make any changes to it whatsoever. I live in a country were there is no google or asus techical support, and third-party technical supporters are dumb as f***. My girlfrind took the tablet to 2 other places before giving it to me and they said to her that "it didn't have any software installed" (which was wrong) and that "it was beyond repair" (which was also wrong). The only thing I want to know is: is there any way to fix it now? or do I just have a very nice and fancy paperweight in my hands.

Ha, yes...same boat and similar situation happened where USB became disconnected during bootloader flash. Surprised there haven't been any snarky comments made on your (and now my) situation. I have a totally non-responsive device now and Windows is also not recognizing the USB device (because it does not respond back when attempting to connect/mount). Looks like the only magic at this point would be cracking open and trying a completely different path to restoring, otherwise it is time to find a nice door needing a doorstop!

Hello
I have a Big Problem
I tried to flash a new firmware and now my Shield Tv does not start anymore.
the Light does not work anymore
if I connect the Device via USB with the Pc it only recognizes an APX device.
what can I do to flash a firmware again?
You are talking about the green light that indicates that it is powered on, right?
I had a similar issue when trying to flash the recovery image on my Shield TV, also a 2017 16gb. He's dead, Jim. I had to live chat with a rep from Nvidia. I told them it isn't powering on and the green light didn't light up. They tried to resolve it with a replacement AC adapter, which didn't work, I contacted them again and they sent me a replacement Shield.
that's exactly what I mean

Hi
ok that sounds good but I have the shield now about half a year and the firmware I wanted to install is not official,
had already tested several systems and I'm also not a Beginner but after the last restart, the Light was no longer on and I get no Picture.
should say that I have the Shield Tv 16Gb 2017.
what should I say best to the support?

according to Nvidia support when I spoke to them if the shield is recognized as a apx device then it is hardware failure
Hardbrick. Only fixable through nvflash. Seems like you hace not bootloader anymore. Maybe wrong Rom for the wrong Device. I had this Problem myself. I flashed the 2017 Rom at my 2015 Device by Mistake. I still wait for someone to find a way to flash the right bootloader through apx Mode.

I was told by Nvidia support that if device is seen as APX that it is hardware failure
hardware failure means hard drive or board level? If it's hard drive problem, someone already posted a way to build the OS from 0
I have a 2015 model with same ailments. Waiting patiently for people smarter than I am to come up with an answer.
i saw on gbatemp an on various gits where people made thier own apx drivers to exploit the tegra x1 vulnerability in the switch and on the shield tab but sorry i don't have the sites exactly thats what made me check here again. It can be done and with the exploit you can kick it out of that mode
So. I have used the unbrick tool several times before because sometimes I want to go back to out of the box factory. Locked bootloader, the whole nine. Well, it failed, so I unplugged it to try again, and no matter what I do, I can't get my computer to recognize that it's connected to the computer. I've been trying the holding volume up while plugging it in while in test mode. Like I said, I've used it before. I made sure I had plenty of battery life before I tried it, so I know the battery isn't dead. Do I need to look into getting another phone, or has anyone had a phone brick this badly and know how to fix it.
Just to rule out the obvious, have you tried different cable and computer?

I'm not very familiar with windows, you could try booting a Ubuntu livecd and typing in a terminal: dmesg
Then plug in the phone.
see if you can find any reference to the device being connected within the kernel messages.
How did you brick your OP in the first place? Does it still charge?

The fact it does not even charge sounds like a hardware issue. Even when its bricked it should at least charge.

This is an EPIPE error, this means the device is not answering the USB protocol requests and the pipe is broken.
In my experience this has always been due to a faulty cable, but in your case I'm afraid the device is juts not behaving as it should.
Next step would be to troubleshoot the hardware; This is not my area but maybe someone experienced can help out indicating what should be the next steps.
It may be that some small hardware parts could be replaced or the damage could be more severe.
Did you power down the phone then hold the power and volume down buttons at the same time to try and boot directly into recovery? If you can boot into recovery and have TWRP you could format the data on your phone using TWRP. That would erase everything on your phone except TWRP. Your computer would recognize your phone as an external hard drive and you could copy and paste a full ROM zip onto the phone memory and flash it with TWRP. If the tool you used installed the stock recovery I'm not sure what your options are but being able to boot into recovery would be a sign that your phone isn't actually hard bricked. Using automated tools to flash your phone is a really bad idea. It is much safer to flash manually.
I think there is close to zero chance that you have a hardware issue based on what you described. I've never heard of anyone hard bricking an OP5 so I think your phone is recoverable. If you can't figure it out a competent phone repair shop should be able to get you up and running again.
There's also One Plus tech support but if you try to get help from them I would probably just tell them your phone got borked after an update. If you tell them the entire circumstance they probably won't even try to help you.
Good luck.
Did you try holding power button for >40 seconds?

If it's totalled then one plus will have no idea what is wrong either, send it back mate.
After reviewing all the replies, which won't work for you.
Way back in 2016, I faced the same issue with my op3. My issue was fixed by one of my friend by detaching the battery and reinstall the battery so that the board can boot. If that doesn't work for you, then suggest you to please check the type c connector funtionality.

Hey!
While I was calibrating my fingerprint, phone suddenly turned off and went to recovery with screen off.
I managed to reflash stock rom through fastboot and it boots to system fine, but the screen stays off and the front camera keeps trying to open while playing the MIUI camera sound (sometimes, while booting, the camera does manage to open once, kinda like it's calibrating). Some playing around with ADB and it seems that the SIM isn't recognized either.. antenna maybe?
I opened the phone up and checked everything, there's no visible issues with the electronics, however it could just be the inside of a cable that died?
Does anyone know what this could be? I noticed the screen, fingerprint reader and antenna are all connected to the same removable PCB, but the camera isn't so that's odd.
Aren't we moving way too fast here? Like wtf is happening rn?
First: Explain in detail from the beginning please if you want help.
Second: Please state exactly what is your issue, and the ROM version of your device.
I don't think what you just did is the cause of whatever problem you're facing, do you mind telling me the source from which you got this phone? Otherwise you might want to send it to a service center.

It's a bit of a long one, so I didn't want to bother too much with the details if anyone knew what those specific issues could be caused by, here goes though:
I am on a Mi 9T bought on Amazon Italy in July 2019. I cannot comfortably send it to a repair center due to every authorized shop around here is just a drop-off point for Xiaomi RMA. I talked to them and, due to (>6 months old) glass damage to the screen and back of the phone, they intended to charge me way more than I can afford, as "solving issues covered by the warranty would require us to replace the accidentally damaged components"
As for what happened:
I was running LOS 17.1 with no issues for a few months. I went to unlock the phone and I heard the reboot vibration, which sent me to recovery (softbricked) but with no screen signal. I assumed it was just a software problem, so I flashed MIUI 12 (global, V12.0.7.0.QFJMIXM) to see what would happen.
As it completed, the phone rebooted itself, the MIUI logo popped up and it went to system (seemingly) without any issues.
I went through the initial wizard and played around with it. everything seemed fine and I even made sure the screen did work in recovery and fastboot. Later, when I went to setup the fingerprint reader, the screen went blank for half a second when I first touched it, and then the same screen death -> reboot to recovery.
The phone was softbricked again, though, this time, reinstalling MIUI didn't yield the same success. Now:
MIUI boots "normally" again
The screen isn't working at all
The front camera opens, as if it's calibrating, when system boots up
The front camera randomly tries to open again every now and then, failing to do so as if the motor is stuck, while MIUI plays the camera closing sound.
Meddling through ADB, the antenna doesn't seem to be working, but I can't be 100% sure due to the methods used
The power and volume buttons, speakers, and the charging light all work.
I have opened the phone up myself, thoroughly checked every cable, connection and PCB, but there is no sign of damage. I put it back together and the same issue continued.
My best guess is that something inside the fingerprint reader went bad and shorted something else.
What that something else is, I couldn't find out. Given the antenna, screen and FOD are all connected to the same little PCB which then runs a couple cables to the motherboard, I am now in the process of finding a couple replacement cables to see if that fixes anything.
As I mentioned before, repair centers are not an option due to the lack of anyone who's willing to help me for less than a good chunk of the price of the phone.
Interesting. So basically what happened is due to the initial soft brick and accordingly you flashed a global MIUI 12 ROM, which in return brought you to the second soft brick which caused some issues within the hardware of the device.
Now you're stuck with a faulty screen, a faulty camera and a faulty antenna.
I don't have the skills to play around with the motherboard and the phone circuit. And I don't care which youtube tutorial you saw, you should have NEVER done that - Of course unless you're actually experienced in that manner, then I apologize for speaking with such prejudice -
I can't help you if you messed up your phone circuit since I have no knowledge about android hardware, however I can safely assume that what caused your issue isn't related to hardware.
I think the issue is caused by an incomplete flashing of a ROM (In this case MIUI 12 global) OR flashing a different variation from your device.
e.g. you flashed only the ROM, but didn't flash the other components of the ROM.
Needless to say, flashing a variation of the ROM that isn't meant for you device can be a disaster recipe.
I recommend flashing LOS again, since you can't go back on Xiaomi devices due to rollback protection.

I understand why you'd think that and have seen people do similar stupid things, however I didn't watch any youtube video and know what I'm doing quite well.
I made sure I flashed the correct rom through fastboot to restore everything to stock. I did try to reflash LOS and whatever else (though it's kind of a pain with adb shell), but it doesn't fix the problem, sadly.
That's why I'm betting on a HW issue.
The fingerprint reader and everything else worked flawlessly in LOS for months, but it made the screen go blank and bricked the device in both LOS and fully functional, stock MIUI.
Currently, I'm battling with this damn thing to get USB debugging working while booted to system, so I can do a few things like cast the screen to my PC and see what works from there.
I have access to fastboot and recovery, but everything I know (editing build.prop or patching the boot image) didn't work so far. Do you have any idea what I could do to get that done?

If the touch screen is dead then you can use mouse and OTG cable.
If it is completely black then you can get usb c to HDMI cable (Also usb c hub might work, like this one). Or you can use playstore on pc to download and install apps like (Screen stream over HTTP) on your device, just make sure your device is connected to the internet and you're signed in on your phone as well, you might have to type in the screen password if you have one.

I have access to fastboot and recovery, but everything I know (editing build.prop or patching the boot image) didn't work so far. Do you have any idea what I could do to get that done?

I don't know why bother with build.prop unless you have the wrong fingerprint prop. Then you can get the correct one from your device's stock ROM, though I think this is irrelevant to your issue.
All I can think of is:
Wiping dalvik cache, though you might have already done that.
Trying other custom ROMs from here.
You may try to get your device rollback index and installing a MIUI ROM that has index higher than it, and see if that works.
That is as far as I can help, unfortunately.
I have zero knowledge when it comes to hardware, so I can only help with software issues. If none of my solutions worked then sorry for wasting your time :/

Wait, does it actually just automatically use it as a 2nd screen if I connect it via HDMI?

Sorry, I didn't explain myself, I'm looking for a way to enable USB Debugging without a screen. Thinking that using adb in twrp is the best way, but I can't manage to do it. Do you have any ideas?
If I can get it on, I can then use things like scrcpy to get screen signal through USB.
Main problem with everything else is that the screen is 100% dead. Even with usb otg I don't know how I could possibly get through the setup wizard haha

I haven't tried it myself, however it should detect it as a second monitor. Give it a try the cable isn't costly at all anyway.

TWRP has debugging mode on by default, however that strictly applies to recovery and fastboot modes only as debugging mode is pretty powerful and can cause security issues. So you better forget about it.
I saw one of my friends who owns an authorized service center use some cable connections to get the screen to display on another touch screen. If you have the capabilities and resources I recommed trying it, though don't mess too much with the motherboard.
Just a question though, can you confirm if the touch is working? If not then there's a chance - Although slight - that this is just a UI problem (Which is pretty common in MIUI ROMs for some reason). In that case deleting dalvik cache or completely reflashing the ROM might solve the issue.
I may not do much help but certainly someone there can help so it's better if you include "usb debugging" in the title and/or the tags. Like changing the title to "Enabling usb debugging without screen" or "Screen is dead, need help to flash ROM"
Using proper title and proper tags can get the right person to help.
