I made the mistake of buying this tablet, so -thanks- Walmart for the unexpected, unwelcome headaches.
I got it for reading ebooks, because of the slightly larger screen compared to my phone. I saw it was limited when I got it home and turned it on, but I was still able to install a couple of book-reader apps so I thought it would be OK for my purposes. But when I plug it into my Windows 11 laptop with the USB cable the tablet doesn't show up on the computer. I have books on the laptop to transfer over.
Is there any way I can force the USB to be a data transfer connection instead of only a battery charger? There is no "use USB for" option when it's plugged in, like there is on my phone. Is there maybe a third party app I could install that will enable this -usually- normal function? Thanks, any advice and help is appreciated!
Hi @Lookstwice
Enable MTP:
Settings > Connected devices > USB > File transfer
Enable ADB:
Settings > About Tablet > Build number (7 x tap)
Settings > System > Advanced > USB debugging
Some people like Calibre on their desktop for organizing books. I believe that understands MTP.
Me, I use my adbsync.exe (in my sig) to synchronize directories. It uses ADB (duh).
Also check out this thread on the 8" which has some info that may be applicable:
https://forum.xda-developers.com/t/new-generation-3-onn-tablets-are-now-available.4464147/
Hello Renate and thanks for the advice!
I did find the developer mode and turned on USB debugging. Also, I selected File Transfer under Default USB Configuration.
Under Settings > Connected devices there is no USB on my tablet, only +Pair New Device and Connection preferences, Bluetooth.
The tablet still doesn't show up at all, when I connect via USB to my laptop.
Is there anything else I should try? Under System > Developer options maybe? How about OEM Unlocking? Disable adb authorization timeout? Thanks!
Are you sure that you have a data cable? Cheesy ones only supply power.
If you're connected to Windows enabling/disabling USB debugging should make it "bong".
To check out if I am using an inferior cable, I switched to my cellphone cable. It works fine on my cell, but no luck with this tablet. I know it makes no sense!
Thanks for your help anyway. I'm open to any ideas.

Sorry, I missed your response.
These devices come up in the MTK preloader whenever they reboot.
You don't actually need to load a loader or do anything.
Connect the USB. I presume you're using Windows? Does it "bong"?
Use the regular Android reboot option on the power menu.
Does it do a bunch of bong-ing and Windows flashes popups complaining about devices?
You may have a hardware problem and you need to return the device.
Wow, Renate, you've got some serious skills. Pretty impressive to turn such a low-end device into a custom machine...
I'm having trouble pulling the boot.img from this device... If anyone was willing to share the stock boot.img for the 100071481 that would be SUPER appreciated...
otherwise I'm just going to keep trying to get this MTK client thing to work although nothing seems to get the device to be visible...
Joined the forum to post this message though I hope to contribute in the future! Thanks!
@oneiromon Yes, try the (Python) MTK client
I've had problems getting that to run under Windows. I finally used a Raspberry Pi with Linux.
I was working on writing a native Windows MTK client but I haven't got that working yet.
After successfully writing a native Windows EDL (Qualcomm) client it was a bit disheartening to dive into the MediaTek gobble-dee-gook.
FWIW: I've not had luck with fastboot boot whatever.img
It works fine with fastboot flash boot whatever.img, then fastboot reset
@Renate - THANKS! for all your help with this onn tablet . Sorry I've not been keeping current on responses. I use the tablet to read books on while getting medical treatments and I was able to upload the files to my Google drive and then download to the tablet.
I'm on a Windows 11 laptop and it doesn't "bong" when I attach the tablet. I'll try the reboot option and let y'all know .
@oneiromon - I totally agree with this statement: "Wow, Renate, you've got some serious skills."
@Lookstwice I haven't got up to Windows 11, so maybe it's hiding some stuff from you.
It could also be that the 7" has some differences to the 8"
The USB/VID of my 8" is 0e8d/201c (MediaTek)
Try using UsbView.exe
See if anything appears/disappears as you plug in. For sanity, check against a known working device.
Oh, and if you're thinking reading, you really ought to consider Eink devices.
Yeah, a lot of them are annoying and underpowered, but see if you like the concept first.
I like the Onyx Poke3, but buttons/no buttons is contentious and personal.
I use no buttons but a tiny Bluetooth clicker. I love it!

I'm a noob, not sure where else to get help on this site about my problem... I'm using a ASUS Notebook K53E Series laptop computer running Windows 7 Home Premium 64-bit Service Pack 1... I'm using a HDMI to project onto a HD TV I have a USB keyboard and mouse hooked up, both Logitech... The problem I'm having is, both the mouse and keyboard keep disconnecting on me... The mouse will go first' I'll move it from one USB port to the other, and it will work, but then stop working again... The keyboard will just stop working, even if I move it I can't get it to reconnect... I have to shutdown my computer to get everything to start working again, but it will only last about a half hour before they stop working again after the reboot... I've went into the device manager, under Universal Serial Bus controllers > Generic USB Hub > properties > Power Management, and unchecked "Allow the computer to turn off this device to save power... This does not help... I then uninstalled it, and rebooted my computer, still doesn't help... I then tried to system restore, I couldn't because I had no restore points, I have no idea why I didn't... I then look if there was any system updates, there was, but minor updates, I updated them anyways, still no go... I'm only having problems with the USB mouse and keyboard... My laptop touch pad and everything else works fine...:fingers-crossed:
... why are you looking for help here? This isn't a tech support forum, it's a dev&hacking forum. It's also not a Win7 forum... there are better places on the Internet to ask for Win7 support! Asus themselves would be a more logical choice, for example.
You could try checking the Event Logs for any abnormal USB events, but I don't really know. Are there any other mice / keyboards you could try, or could you try the ones you have on another computer? Does it work at all to just unplug the mouse/keyboard and plug it in again? Do the devices lose power (lights go out) or do they simply stop responding correctly? Do other USB devices (phone, camera, webcam, headset, flashdrive, whatever) keep on working if you leave them plugged in for a while?

Sorry, like I said I'm a noob... The reason I asked here, because I thought it was a general question for windows OS... I do understand its windows 8 tho... I also didn't want to join some random site to get my answer... I also checked event logs, but I'm not sure how to use it... I have no other computers or mice/ keyboards to test with... The lights stay on, like their still connected, but they don't work... I've pulled them out, and plugged them back in, and even put them in other USB ports... But they will only work for a short while after moving them to a new USB port... They will no longer work in the same port after they stop working until I reboot... I'm also not sure if it's ASUS or Logitech thats the problem...
EDIT - solved! I've never noticed that apparently some cheap micro usb cables will not work for adb data connections though they work with other devices such as external drives just fine. Grabbed a 3rd cable out of desperation and it hooked right up. What are the odds? Learn something new every day.
Either I'm being thick or this is just fubared - I have a non-rooted Asus z380m running Android 7.0 firmware ww_v5.3.20_20180809. I cannot for the life of me get it to connect to any of my pc's in order to enable write secure settings for something I'm trying with Tasker (turn gps off requires security?). I've Googled forever, tried every usb driver I can locate (including unsigned installs), ensured that Developer mode, USB debugging and USB config on device is set to MTP protocol. NOTHING seems to enable usb connection to pc. The only way I've been able to get files on & off device is through Asus file manager utility that provides web interface (which sucks).
I also tried a Win7 laptop with the "latest_usb_driver" package and no joy there either.
I'm not the most savvy Android guy around, but doing IT for many years I have more than the average clue. Except here apparently.
Any insights would be _greatly_ appreciated.

Hi,
I am a bit of a Newb to the fire, but have the developer tools going and USB debugging engaged, but when the tablet is connected to either of two Win 10 computers, it does not show up as any kind of device, and in the settings of the tab the USB conneciton is greyed out (presumable because no connection is detected). The tablet charges fine, though. I tried installing fire USB drivers from a link on Amazon, but windows reported they did not install correctly (I had admin privileges too). Has anyone encountered this? My other Android devices are discovered by windows very easily. Sorry if this is obvious somehow...
Turn debugging OFF. That gets in the way of doing what you want.
Debugging is only if you need to send ADB commands to the tablet. Not for straight file transfers.
After turning it off, then your tablet will show up as a device in Windows.
But, the storage won't show up until you pull down from the top on the tablet > tap "USB charging this device" > tap "Transfer files". Then, you can click on the device in Windows and see "Internal storage", and an SD card if you have one in the tablet.
You didn't need to do this in the previous 7th get HD8. Before, it was in file transfer mode by default when you connected the USB to a PC. But the 8th gens changed that. I guess it's the difference between the older tablet OS being based on Android 5, and the new ones now based on Android 7.

Thanks, I did that, and nothing changed. When I pull down from the top, there is no USB notification (though the charging icon works and is visible at the top of the screen).
Have you tried using a different USB cable?

Yes, thanks I have, on two different win 10 computers. So I figured it was something to do with the tablet.
Hi,
My brothers phone screen is basically unusable.
When I connect the phone to the PC it recognises it in Windows but the phone contains no folders. At first I assumed it was because his screen was locked so I connected a OTG and keyboard and using commands managed to get his phone "unlocked" to the home screen.
However this didnt fix the issue.
Reading around it seems I may need USB Debugging enabled (if he hasn't already) but due to not being able to use the screen how would I do that?
Do I need a MICRO USB to HDMI & USB adapter to use a mouse and TV output?
Or is there a way I can fix this through windows using ADB?
At this point we are willing to try anything as all we are looking for is some family photos off of it then binning the phone and I don't want to put £100-200 into the screen replacement just to attempt this data recovery.
All help is greatly appreciated,
Cheers
ADB is the door to any Android device. As long as ADB has not been activated on the device - and the related RSA keys got created - you have no chance to pull out data from device, IMO.
Ok,
Well see the fact when I connect it to windows it shows the phone but not the folders inside, and I can only assume there will be a popup on the screen mentioning to ALLOW/DECLINE transfer etc..
If I use the OTG adapter I can plug my keyboard in and use the sequence SPACE, SPACE, BKSPACE, BKSPACE, then my PIN and ENTER and it unlocks to the home screen.
But because I would need the phone connected by both PC and KEYBOARD at the same time is it possible to get a splitter on the OTG adapter and this would hopefully let me press RIGHT and ENTER to accept the message?
If not then can the phone be connected via HDMI to see if any message is infact popping up??

OK, new to this. To get usb debugging on, click system. About phone, Software information, build number. Click that several times. (AT least 10). You will see a message that you are in developer mode. Go back to home screen. Click settings icon. Scroll to bottom you should now see { } Developers optiions. Click that. Find the section for ADB, enable ADB. Once ADB is up and running you should be able to pull the files. The screen for an android is the desktop, mouse, and keyboard. (PC analogy). You need something to see your icons, something to click, and a keyboard. If OTG acts as a mouse, and you can see the basic display, and have an external keyboard. I think you can do this. I am not sure what OTG is .

1. I cant follow that process as the screen is completely destroyed (no display/no touch), thats why I have been blindly using a keyboard to try and find the setting
2. OTG is ON THE GO , its a small adapter that lets you connect USB devices to your phone.
Sorry about that. I think you are stuck. without some visual clues I think you can not put the phone in developer mode. Did you try just a plugin (via usb) into windows and seeing if there is a pictures folder?
It find the phone in Windows, but wont display the folders.
The OTG splitter I purchased to be able to connect it to the PC and KEYBOARD at same time didnt work as it doesnt supply power (should have checked reviews).
Any other solutions? Or is this a new screen for £200 just to get data?
I purchased another OTG splitter that has a OTG/CHARGE switch so this should let me connect it to the PC and KEYBOARD.
Can anyone give me shortcut keys or step by step on how many times I need to press certain buttons to get down to the USB DEBUGGING section please?
Hello.
I've got my mother's Samsung A20. And i need to recover data, but the screen doesn't work.
When power button is pressed, display flashes the lock screen (wallpaper, current time and so on). And then it turns black (backlight stays on for 30 seconds, and then turns off). Pressing the button doesn't guarantee flashing the display, sometimes it goes black immediately. Touch screen gives no input as far as i know (can't hear anything when trying to type pin). Problem still occurs during and after reboots.
I managed to connect a mouse and keyboard with USB OTG, and i was able to unlock. But the phone has no MHL support, so i can't get any image through USB. I'd try pressing the power button repeatedly to get some image and inch my way through the interface, but the lockscreen interferes.
The USB port is set to Charging Only mode, so i can't copy files to my computer. USB Debugging is disabled, bootloader is locked.
Does anybody have a clue, how to get image? Some way to get data? Maybe some keyboard shortcuts, so i can disable lockscreen and make my way easier? And maybe disable 20 alarms in the morning?

I like to be helpful so I'll try to give you some suggestions but I hope others pitch in who know far more than I do.
I never use the USB cable anymore to operate my phone from my PC (but my screen isn't broken so your situation will be much harder).
I connect to my phone from Windows over Wi-Fi without USB all the time, and I can unlock my screen from the PC, and I can mount my entire Android device as a drive letter on Windows over Wi-Fi, etc., so "maybe" (just maybe though), you can consider using either a WebDav server on Android to access your files and/or adb to bring up and manipulate activities on Android....

However, I don't know if adb will work for you if you can't turn on USB debugging in the first place... but as of Android 12, adb now works completely over Wi-Fi (see screenshots below) without needing the USB cable to establish the initial connection like it used to be prior to Android 12.

If the screen problem is "just" hardware and not software, and if you can turn on Wireless Debugging, you might be able to display your phone over scrcpy or vysor (both of which use adb over Wi-Fi) as shown in the screenshots below on my phone - which never needs the USB cable connection.
Hope this helps, but you seem to need folks who know more than I do as adb/vysor/scrcpy all work for me because I can set up USB Debugging & Wireless Debugging as shown below.
Note that you might have an FTP server or a WebDav Server on your Android phone, and if you do, you might be able to at least transfer important files since they each can mount your entire Android phone as a drive letter on Windows over Wi-Fi (without needing the USB cable).

A20 can have only Android 9, 10 or 11, but thanks for ideas anyway.
I didn't even know adb can work over WiFi, I'll look into it. Hopefully this version can do it too.
Now trying blindly to turn on the screen reader…

Ooops. My bad. I apologize. You'll need the USB cable in Android 11 for a moment to establish the connection first. Then you can switch over to Wi-Fi after that (or you can stay on USB).

I feel for you. I really do. It hurts me when people can't access their phone remotely to get their data back. I am searching all over the XDA site for a solution for you, where I just moments ago opened this thread to help (I'm still searching for you though).
What is the best XDA solution to control Android on the PC & recover data over Wi-Fi when the user suddenly has an unresponsive broken screen?
