[Q] Of TF101 and Possums - Eee Pad Transformer General

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?

Totally Borked TF101

I think I have totally borked my ASUS TF101..
I get nothing on the screen and the only sign of life it shows is that it goes into APX mode..
I have tried to follow many different guides for recovery......
http://forum.xda-developers.com/showthread.php?t=1688012
..... but they all pretty much end with this:
http://sjfm.us/temp/tf101c.jpg
It just sits there like that. I left it for almost 10 hours... No change.
This is a really awesome tablet and I want to exhaust all possibilities before giving up..
Anyone have another procedure I can try???
Thanx
Michale
I'm assuming your unit is a b60 or greater since you're running wheelie? I'm bricked too but I have a b30 and Nvflash has always been confusing to me.
To be honest, I am not sure what TF101 I have.. I don't get ANYTHING on the display and the only sign of life is when I have it hooked to my PC via USB and can go into APX mode...
This is the label on my TF101:

Here's a more detailed analysis of my issue..

Since the last post on that thread, I have tried the PERI package and the package here:

It still freezes at 100% right after the bootloader load...
http://sjfm.us/temp/tf101e.jpg
I am pretty much at the point to where I either have a bad USB cable (waiting for a new one) or my TF101 is completely borked..
I have a friend here in Spain, in the same situation.
no way to restart pressing power button , the tablet seems to be always in apx.
I tried all possible methods, rootkit, easyflasher, reflash with wheelie.
and always the same result, stuck on the same spot as you.
I've run out of ideas already, and just hope that someone who has solved something like this , give us a hand.

That's interesting that you have the exact same problem.. Hopefully there is someone out there who also had, but fixed it. I PMed with a guy and he said to keep trying NVflash (wheelies) and see if it will "POP".. I did that for several hours with no luck..
I'll follow up on this when my new cable gets here. Frankly, I don't hold out much hope that it's going to fix things, but there is always that possibility.
If not, I'll just keep searching around for a TF101 that has a busted screen..
on the screen of my friend's tablet, when the process starts it appears:
Entering NvFlash recovery mode / Nv3p Server

Well, that's very interesting.. Mine did the same thing, except I didn't see any text on the TF101..
When I get home, I'll check it more closely..

Well, apparently I have a bad LCD in addition to a borked unit.. I don't see ANY text on my screen, but the output from NVFlash is identical...
This just keeps getting better and better.. :crying:
I couldn't really find the serial number in your picture, IIRC it's just a sticker with a bunch of numbers and letters on it. Mine peeled off a while ago so I have nothing to compare it to :-/ It should start with a B
Sadly, the only way to make sure that the tablet is truly off is to rip the thing open and disconnect the battery (which is connected by an 8-pin connector). You need a T-5 torx screwdriver to take out the two screws around the charging port so you can pop the bezel off and a small Phillips screwdriver to remove the screws that hold down the screen/rear cover. I had to do this with mine because the only two things that I could get to were APX mode and the stock recovery, but my cable seemed to crap out the moment I needed it even though it had worked a few minutes earlier!

Thanx JTR.. I'll check that...
On another note, I got a new USB cable in. This one actually does worse than the first one. With the new USB cable, I can't even get the TF101 into APX mode..
Something else I noticed that may or may not be related...
When I have either cable plugged in, it seems to take over my USB ports. If I plug in a Thumb Drive while the TF101 cable is plugged in, the computer will not see the ThumbDrive..
Does that indicate that BOTH cables are bad???
Your TF may be done for :-/

i am currently having the exact same issue as you do...can only go into apx mode and nothing ever shows up on the screen. Mine all started from trying to install an OTA firmware from asus...i feel like im about ready to give up
Same problem here.
In fact my tablet work very well but the display died. It works with an hdmi cable though.
In didn't try this but maybe it could fix some thing for you:
http://www.youtube.com/watch?v=yRLcxI2JddQ
I really am disgusted, my display dies two weeks after warranty without more obvious reasons than randomness.
If a lot of people have their display broken (and only the display, with hdmi working) I think we should think complaining to asus... It's not acceptable for this kind of devices.
have you tried flashing RougeXM recovery 1st? Then flash the asus recovery fw from easyflasher in apx mode.
Make sure its in /AsusUpdate dir. You won't see anything on the screen in apx.
I thought I killed mine but EF saved it. Was stuck hanging just like yours is doing so i reflashed & it worked.
Good luck,

Need Help with APX Mode Brick.

Running (was) a stock rooted N7 v1 on 4.3. Bought a data recovery tool off of the play store to try and recover some photos I had deleted. At some point it rebooted into safe mode, my battery was running low and I shut it off to let it charge. Now it's dead in the water. Stuck in APX mode. I am asking if there is anyway to breathe life back into this tablet.
The tablet does nothing on the screen, period, no matter what you do. When plugged in to a computer it sometimes registers as an unknown device, sometimes APX. None of these get you anywhere. Toolkits on these forums won't recognize the device, installing the android development kit and drivers does nothing, executing commands from the command line is worthless because the device won't register. I do not have any "blobs" and have no clue at this point even what they are or what they could have done for me had I made them.
I've searched this forum and found bits and pieces here and there and wanted to start a thread dealing solely with devices stuck like this and what has or hasn't worked and get others input if warranty service was done and the state your tablet was in when you sent it in (locked/unlocked, rooted etc).
Anyone stuck here will have probably tried the same things as I have but here is is a minor rundown...
1) Every button combo press known to man for short, medium, and extended periods of time.
2) Charging with the Original charger/cable for 1 hour, then button presses then charging for 12 hours.
3) Same as above but with different aftermarket chargers at different amperages.
4) Uninstalling and deleting drivers. Trying different drivers. Getting the Android drivers etc.
5) Trying every toolkit on the forums to no avail because the device won't register.
6) Checking to make sure the battery cables are seated correctly.
7) Screaming and yelling at your new paperweight.
My hope here is that I've missed some important thread about recovery and someone can point me in the right direction. Failing that, if I should get a new mobo or try and send it in for warranty service in the state it's in.
Any help would be much appreciated.

I don't know what you tried before to revive your tablet and what the tool did to get you into this state, but generally APX mode can be left by pushing the power button *only* for about 10-20 sec, as long as there us enough power within your battery and the hardware / software is working / consistent.

I don't think I've ever seen anyone in here describe a situation where they observed the tablet in bootloader mode without seeing *something* on the screen.
And as you found out through your reading, using "nvflash" on the N7 is only useful at this time for folks that made prior disaster recovery preparations. So, APX mode is of no use to you (at this date 12/2013).
So, until you see something happen on that screen, drivers on a PC are of no value to you anyway.
It is really unfortunate that the N7 doesn't have a physical charging indicator - that makes it difficult to distinguish between a tablet which is truly borked vs. one that refuses to boot simply because the battery isn't charged.
Holding down a specific button combo (iirc Pwr+VolUp) during an attempt to get "something, anything" to happen will put the tab into APX mode, so it isn't particularly diagnostic that you have observed APX mode once or twice.
Really about the only way to know if the battery in a non-responsive N7 is charged or not is to put it in another tablet or measure the open-circuit voltage. (About 4.15v fully charged & about 3.5v discharged)
The reason that I mention this is that there have been a few reports from users in similar straits as you that report something like "I don't know what happened, but I tried it a few days later and all of a sudden the tablet booted up". Almost every one of those reports involved mentions of low battery conditions, just as your narrative does.
I don't know what file recovery program you used, but I suspect that is a red herring . It might have to have root privileges in order to read raw partitions, and might even want the tablet in safe mode to minimize write activity by *other apps* while it does it's forensics, but it certainly isn't going to recover files by writing in raw mode on a mounted, live filesystem - it would do all it's writing through normal kernel syscalls. That's the long way of saying that a low battery is more likely to be the original source of your troubles.
So what to do now? I think the first order of business is to figure out if your battery is charged or failing to take a charge. If it really is well charged, then a warranty return is probably in your future.
If you can't find a second N7 or a voltmeter, then you could try just leaving it on the charger for a couple of days... but that really is just a "grope about in the dark, wing & prayer" kind of strategy.
good luck
Button sequences & USB Identifiers (VID/PID pairs):
http://forum.xda-developers.com/showthread.php?t=2133986
You are in the same situation I was in - nothing shows up on screen. I got APX drivers to finally install (had to search all over the internet to find them) and that STILL didn't help. I was never able to get it to come back. Nothing ever showed up on the screen.
No combination of button presses helped. I finally gave up and, since my N7 was still under warranty, I RMA'd it back to ASUS. It took about 3 weeks, but I got it back with a new motherboard installed on it.
It was borked and your's sounds the same way as mine. Just either register your N7 on the ASUS website and RMA it that way, or call it in over the phone and RMA it that way. Hopefully, you still have the box your N7 came in because you'll need the serial number.
Others have stated you can get it by opening the back, but that will void your warranty. I do believe you MUST have the serial number, so find the box and get it from there.
Also, you'll definitely lose everything that was there, especially if they replace the motherboard. So hopefully, you backed it up. I backed mine up just before it got borked, so I was lucky.
Good luck!
I am wary of trying to do the battery swap. I went and bought a new version after it crashed but I would be voiding both warranties to try the battery swap.
I do have the serial number if I want to try and get service.
I have done some reading about "deep discharge" battery issues and I suspect this may be a part if it but I have tried leaving it plugged in for days and nada.
I don't know if there is a way to "shock" or jump start the charging process and I am going to put the multimeter on it tomorrow and see what I get.
Thanks for everyone's input. I will keep you up to date.

[Q] Formated Nexus 7 2012, now what?

Hello all!
I'm just guna say, this might get long winded so, TLDR, Nexus 7 has no OS, I can get into the boot loader, the only thing I can actually do is get into TWRP v2.8.01, computer doesn't recognize it, can't get it to even see a flash drive that I've formatted to Fat32, now what?
For those who want some background. I got my N7 refurbished from ebay, if that matters at all. First thing I did was update it to Kitkat and root it. Installed some apps and was happy with it for a few months. About a month or so ago it stopped connecting to the Google Play Store. I wasn't bothered by it too much. But as time goes on, I find new apps and would like to use them. But obviously can not.
So, just to be safe, I wrote down all the apps I still had on it just in case they didn't want to load back up. Did a factory reset, still couldn't connect. Looked online and cleared caches and stopped services. Still didn't work. When I went onto the GPS, heh, on my computer it said that I had no devices so that was a clue of some sort. I could still go onto Youtube and log in and use it just fine. Just nothing in the store. So I decided to try something else.
What that was was to clear all my data with TWRP. Went to put in my email and password, couldn't connect, tried another wifi connection, still no go. I was able to use it, but the Play Store still didn't want to play nice. So in a bit of, "rage" we'll call it. I formatted it and now I'm where I am now. With a tablet that won't boot, just sit at the Google logo for up to 5 mins, as long as I've let it sit there for anyway. I have downloaded the Nexus Root Kit and tried to use that, but my computer won't even see my N7 now. In the bootloader or TWRP. So I can't even get anything onto it now.
So, what now? Do I have a bricked tablet that won't do anything or is there something an Android Guru out there can help me with? I'd like to keep it. I mainly used it to read and for various videos.
I have posted on forums.androidcentral but after a week and almost 300 views, no one has made any comments. I'm sorry for my ignorance if I'm missing something.
Thanks! I shall be hoping for good news.
So, does ADB recognize your tablet or not when you type "fastboot devices"?
I take it you mean shift+right clicking in the platform tools folder, open command window here, and typing that into the command prompt? If so, then no, it doesn't show up.

Can you go into the bootloader? Did you install the right drivers?
I can get into the boot loader just fine. Recovery sends me to TWRP 2.8.01. I've got the drivers from the Android SDK Manager, Rev. 11 apparently. Would that be any different from the standard drivers that get installed when you hook up the N7? Well, when it works?

And if doesn't work check in device manager.
If it works flash the latest factory image and then you will be good to go
I've already had that installed and set up and nothing pops up in the device manager. I've also tried all the usb ports on my computer to no avail.

Then try the driver manual in nexus root toolkit
I can follow the instructions, but that doesn't resolve the fact that my computer can't see the Nexus .
go into device manager and delete every single entry that suggests anything to do with a phone, tablet, google device, nexus device, ETC. if you dont do that first, this will probably not work.
once you delete every single entry in there, go to the top command bar and somewhere in those menus is an option to show disconnected devices. delete everything again as above.
now, does your tablet still charge on the AC plugged into the wall? does it still charge when plugged into the computer usb? drivers are NOT required for usb to supply power. if so, the usb connector is probably OK. if not, your usb connector may be toast.
next, connect to the computer. does windows show any device connected? if not, try a different usb cable. report your findings back.
Sorry for the late reply.
There is nothing in the device manager related to my Nexus, which is odd, it had entries for flash drives, a camera, and my phone. All of which were in the disconnected devices. I got rid of just for the sake of it. Nexus charges just fine, either from the wall or any of my usb ports. If there is no way to make ANY computer see my Nexus, is it safe to say it's bricked?
I do have a cousin who's fluent in Linux if that means anything. I know that Android is a flavor of it. Might work better if both devices speak the same language. Grasping for straws I know.
Again, thanks for the help fwayfarer, GtrCraft, and Fobos531!
If I am reading right, you did NOT try a new USB CABLE yet, did you?
Try a known good USB cable, what I mean by that is try a cable you KNOW works for data transfer on another device and report back.
Connecting it to a Linux machine isn't going to make any difference in my opinion.
I have 2 cables and they transfer things just fine with my phone and my Kindle. I just downloaded everything off of both things, and transferred them back. No issue with the cables. I just popped open my Nexus and it looks like the usb connector and ribbon are fine. I did wiggle them a little but to no avail.
Pull the battery cable, smash the power button for a few minutes, reconnect and try again. It won't recognize a USB thumb drive in bootloader or recovery to my knowledge, BTW. I noticed you mentioned it not seeing one.
I unplugged the battery, hit the power switch for a while, plugged the battery back in, plugged the usb back in, nothing. Still nothing. I had read before that you can put the version of android you wanted on a flash drive. With an otg cable you could use that to update/install what you wanted.
You're probably right, I haven't tried using one in recovery for a long time. You didn't change the battery or anything recently did you?
Nope, haven't replaced anything in the Nexus. The only thing that I could think of that could be wrong is the usb connector. But for it to "fail" at the same time I formatted everything, too much of a coincidence.
Over a week bump
I ran into a similar problem about a year ago. Unless your tablet is connected to the computer you will not see it show up it the windows device manager. You should be able to connect your N7 to a work computer & it should go out for the drivers. If not, then you are Sol. You might have a blown main board.
The only thing my N7 does when I plug it in, is that it charges. That's the only thing I can get it to do. Well, this sucks. If I really have a bricked, or worse, tablet, it's still good for its screen and other bits.

NuVision - TMAX ( TM800W560L / TM800W610L ) Information

I wanted to start a thread to solve some minor headaches regarding NuVision tablets. Specifically the TM800W560L, but may include others.
The manufacture is TMAX, and the brand is NuVision. Some of you have these. I picked up the 560 at the Microsoft store, a couple of days before Christmas, 2016. I ghosted the factory image as backup, and wiped clean to start from scratch, using Windows 10 Pro.
Let's say my hack started at the Microsoft Store, social engineering a sale of $25 for the unit. Yes you can get these for free, if you were buying a Windows Surface, but why would you want this if you have a Surface? It's such a terrible device to support for the sod who got one...
This unit is the most similar to the HP Stream 7, MSRP $79. I have a couple of these as well. I a bit miffed that, although the CPU is 64-bit, we can only use 32-bit Windows. This produces some problems as only 64-bit drivers are readily supported via Windows Update. I have made use of some of these drivers for the 560 to solve some problems.
Lets get down to the issues at hand:
1. The Camera drivers.
OV2680 ( OVTi2680 Ven_OVTi&Dev_2680 )
OV5648 ( INT5648 Ven_INT&Dev_5648 )
Problem: For every Windows Feature Upgrade, the drivers are wiped out and replaced with some non-functional version. Frankly, I don't think I have been able to get the cameras to work at all. At least, not by using the Windows 10 Camera App. I pulled a litany of drivers from various sources and I can get them to at least seem okay, as far as the device manager is concerned, but not much beyond that.
2. Intel Chip Set drivers.
Problem: Much like the camera drivers, for every Windows Feature Upgrade, the chipset drivers are updated as well, but then the supplied drivers are non-functional. This results in the lost of touch and gravity sensors, among other functions. This requires the use of a USB OTG adaptor, (Yes you can have USB and power at the same time!) and reinstallation of the original chipset drivers.
All in all I get the sense this is abandoned technology, and I feel that no-one particularly cares. In addition, I am a little bored with this thing, and I would like to see if I can make it better.
If anyone has questions or advice, I am open minded, but it should be sincere.
Thanks,
I picked the TM800W610L. I will see if the camera drivers and chipset drivers from this model will work for the 560. However NuVision has reduced their driver set to bare bones. In some respects this is admirable, but in my case, it leaves little hope that there's any 32bit support.
For the uninitiated, the 560, although has a 64bit CPU, the BIOS only boots 32bit Windows. This is the same situation on the same CPU, for the HP Stream 7, which I am also leveraging for support.
I have been able to dig around a little bit, regarding the BIOS firmware, for both models. Geekbench is a nice repository of data, for a shallow dive.
This is what I have, for known BIOS revisions:
I have the installer for version H, supporting the 610.
I can backup version R, installed on my 560.
If anyone is interested in an "update" from an older version, it would be interesting to get a backup of what you currently have in exchange for an update.

I just picked one of these up myself (the TM800W560L) and am working on getting it upgraded to Pro (and put on the Insider preview program, because I like my devices consistent) at the moment. I was a little sad to see that these machines have 32-bit UEFI effectively making the 64-bit enhancements useless and limiting software support to 32-bit only (that immediately threw out my plans for using WSL/Ubuntu on the thing since Windows Subsystem for Linux is a 64-bit only feature), but after a couple hours with this tablet, I'm really enjoying it. It took about 4 hours to install the latest batch of updates, but unlike your own experiences, all my drivers still worked after the upgrade from 1511 to 1709 (Build 16299).
I did see some very negative reviews for the product on Amazon, mostly about customer support, so I knew what I was getting into when I ordered it.
EDIT: My gripes about the device were apparently for a defective device. Got a new one after the note below caused a brick and have had a much better time with it.
Important! For my first real contribution to this thread, I wanted to give a warning, don't mess with the BIOS options if you can help it on these devices. I simply changed the "Boot to State when Power is resumed" from G0 to S5 and the tablet no longer powers on. It's charging, but nothing is happening from the buttons. So I guess it's to the exchange with this one.. Learned for the next one though :/ [Update: Turns out that it caused an actual brick, lesson learned, don't mess with the Power Management firmware settings! There's no good way back from a brick caused by UEFI firmware settings, you apparently have to reflash the BIOS using an SPI programmer to fix those. These manufacturers really should be designing their firmware better (and not using 64-bit firmware on a 64-bit processor, shame on them for that travesty!)]
Edit 2: I ran into an actual issue that I can reproduce pretty frequently. With the native Windows auto-rotation on, going from Landscape to Portrait (or vice-versa) leaves the touchscreen in this weird state where it's still looking for touch input from the previous orientation. Not sure if this is a Windows 10 version 1709 build 17043+ bug, but it appears to be, as the issue does not happen if I turn rotation lock on and manually change orientation. It's an interesting issue to say the least. [It appears after browsing the feedback hub that this is indeed a Windows 10 Insider bug, if you are affected by this, turn off auto-rotation and then manually rotate the screen using Settings, the touch input works as expected then.]
Hi, thanks for the great info! I'm trying to start a little robot makerspace and wanted to mount these little cheap tablets on mobile robots. The only issue appears to be not being able to use USB devices while supplying external power to the device. It sounded like you mentioned this is somehow possible, could you elaborate on that?
Thanks!

I can confirm the strange rotation behavior, on the 610L. I got out of it by hooking up an OTG cable, keyboard and mouse.
Boot up and log in, rotate to landscape and reboot, not messing with the touch screen. After the reboot, the touch screen worked in landscape, and seems to be in sync again.
I installed 17083, that was a chore, and all seems well. However I am getting app crashes, which I think is an OS issue. (currency ran sfc /scannow - no probs. And dism /online /cleanup-image /startcomponentcleanup /resetbase) Next is to run chkdsk and reboot... I have no real hope this will take care of things until the next fast build, which could be in a week or two at the moment.
To get the recent build installed, I had to run a custom script, to clean up all the known temp and softwaredistribution/downloads folder. Additionally I removed the upgrade assistant and one drive. Then ran the Windows Update trouble shooter, and ran (compact /compactos:alwasy) and set NTFS compression on the C drive, ignoring all errors. I was able to get 16GB free, and finally able to install the latest Fast Insider's Build.
Some of these things are not recommended, however extreme conditions require extreme measures... 32GB MMC Crive is a bit restricted.

I am having mixed results here. I plainly am not getting good results with an OTG/HUB combo with three power settings. I am not getting power and USB/date to the micro USB port, as the same time. It's either/or.
610L - Nope, one or the other. I originally thought it was possible, but it's not.
560L - Nope, just confirmed, same result as the 610L - will charge in power+data mode, while completely off.
I have confirmed as well, 17063 build, on both the 610L and the 560L, has this strange screen rotation, mouse, touch screen orientation lock thing. That is, the screens rotate, but the touch alignment does not. The mouse pointer only moves in the same space as if it was prorate mode. Touch is fully prorate mode, while the screen rotates to landscape. Then got the BSOD (green screen)... Rebooting while in landscape mode, (requires a mouse), does fix the issue. Touch alignment comes back with screen rotation. (works on both models)
I see a future problem which I think we will have to address on our own. No help from TMax/NuVision I suspect.
When the microcode is finalized by Intel, we will have to come up with a solution to update the code, to protect against Meltdown and Spectre.
I have doen this before, prior to Compaq merger, on the HP VLi8 and VL400. But I don't know if it's possible to inject new microcode on the TMax firmware/bios update.
As you can see above, I have listed a number of firmware for our tablets, I am hoping we can work with some recent purchasers and see if there's an arrangement, where we could come to trade.
The USB OTG ACA support is weird. There are times it does work and times it does not. I have two USB OTG hubs that support supplying the tablet power while USB OTG is in use. With one hub, this works fine; with the other though, it will either not charge, or it will claim to be charging, but I assume not receiving enough power on the tablet side to charge the tablet enough while it's in use. It does however work, I have used it multiple times already with my 560L.
As for storage space, yes, I recommend running
Code:
compact /compactos:always
after each update. You can also get away with storing your user profile on the MicroSD card (and applications, thus rendering the internal storage an OS only drive)
As for my previous complaint about screen rotation, this disappeared after the upgrade to 17083. It was confirmed to be a problem with the Desktop Window Manager service by Microsoft and even had a fix posted to the Feedback Hub entry for the issue.
@CraveTech It may indeed be possible to modify our firmware, but the risk of doing so may outweigh the benefits. Windows already has user-mode mitigation of Spectre and Meltdown that isn't dependent on the microcode to be installed. We also have to worry about the possibility of bricking the devices without recovery (at least in my case, as I don't have access to an SPI programmer, nor do I feel comfortable cracking this thing open) seeing as a single option change in the BIOS effectively bricked the device.
anyone try to unrar the current image from nuvision for model w610L
test the archive and i get errors.
same with drivers.
tried newest unrar and also older version.
wtf??

What is the model of the one that works for you?
I just got a TM800W610L the other day and have been looking for one that works with this tablet.
Thanks

the exact hub I had the best experience on so far (I am still buying and trying hubs) was this one: https://www.amazon.com/gp/product/B00LTHBCNM/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1
It charged when it said it was charging and had no qualms with the other devices. There's a Cerrxian branded 4-port rectangular hub which doesn't seem to work well at all for my devices. Even when the Cerrxian says the system is charging and the system shows it, it still dies. I assume that it just isn't supplying enough power to the VBUS :/

Interesting. I had seen that one on Amazon and quickly glossed over it since it had a switch for OTG/Charge, so I assumed it couldn't do both simultaneously. At $7 I'd say it's a cheap enough experiment though. Thanks for the info.

Ya I was surprised too, but it worked with my Nexus 7 and LG G2 with their ACA enabled kernels. I had to fidget with the switch a little before charging started, but I was able to confirm in Ubuntu Touch on the Nexus 7 that it still saw the USB devices via lsusb. I seem to have lost that exact hub within the past week or so, but I had used it last month to charge the tablet while reinstalling Windows from my flash drive with a keyboard and mouse attached. I can't testify that it actually charged the device since I hadn't been able to see percentages (being in Windows setup and all), but the charging indicator was on, the screen was as bright as Windows normally makes it when charging, and it didn't die while the device was at ~15% battery before starting the installation. The Cerrxian hub couldn't do that and the tablet died while attempting installation, So I assume it was charging the tablet, or at least provided enough power to keep the device's battery stable.
I also just bought another 3-port hub from Acasis, another Chinese company making these cheap devices, but so far, I have yet to get that hub to charge the device either. So it seems that this is a very specific type of configuration inside the adapter, but the device does support OTG+Charge.
That said, Windows itself (at least the desktop versions) does not actually support this feature according to Microsoft's USB driver documentation. That it works at all seems to be a bug in the USB driver, or perhaps the adapters are doing something strange to trick the device into pulling down it's own VBUS and using the external one, possibly independently from the OS (Firmware USB drivers maybe?).
Does anyone have screenshot of the BIOS main menu and the save and exit screen? I'm trying reset to the bios. I was messing MIPI and eDP. I thought eDP was meant for external display port.
lol I fixed it. I gamble on different version of this tablet. I press F3 and Left arrow key for yes and enter. Then I press F4 and Left arrow key for yes to save and restart.

Glad to see that you fixed it. I would recommend against modifying the firmware settings if you can avoid it, especially any power management settings as changing one of those can completely brick the tablet leaving you unable to even enter the firmware.
EDIT 2/27: I came across my other OTG hubs and have some bad news, it appears that the OTG+Charge works on the 560L, but doesn't on the 610L. Perhaps NuVision changed USB chipset revisions between models?
Just picked up the 610L last week for $66 as a small option to use a program I need mobile. Updated to 1709 after a struggle (why Microsoft, why?).
Ran great for a week and now it’s starting to freeze and BSOD with mainly “Clock Watchdog Timeout”.
Not really getting any indication of why, I know I can run a log dump, but I often can’t get it to stay on log enough. It will even hang and crash when trying to wipe/revert.
Anyone have any suggestions?
Been a long time since I was active around here
update:
Was able to locate the stock ISO files and made a bootable usb. It’s currently restoring back to OEM status.
The installer is another language, but it’s working.
I think I won’t be install updates until I finish this project I have to do.
Another update:
Getting an intel framework and thermal error in the logs, which I notice while the device gets hot while charging and operating. If I let things be without charging it stays cooler.
I’ve only had had one BSOD and it was for System Service Exception but the logs don’t show much.
I let things update overnight with it plugged in and the screen off and it was still operating this morning.
Not sure if this is a driver issue or not. Seems that way.
Been trying to restore this but get an hour into the nuvision software and it times out. Anyone have an idea how to get this back to stock?

Screen dead + Front camera keeps trying to open

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 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.
