Hi,
i have a NT , when i plug in the cable to my pc it shows he usual USB mode.
is there anyway to have it in usb mode but be able to use the tablet at the same time ? in other words get rid of the damn pop up and let me use it while its in usb and charging mode ?
thanks
you could try disabling automount... maybe the USB window is triggered when the SD is mounted for computer use.
That is absolutely correct. If you don't know where to find automount, it is accessible through the nt hidden settings app.
ive also been seeing a weird issue , ive done that in the past , but when my tablet is connected to power / computer usb cable to any power source my touch screen is funky , when im on the lock screen i can do stuff , i can pull the bar over to almost get it to unlock but when and if it does its funky , i just kicked it out off of auto mount and i have what i want except touch screen is not actually working , if i unplug it from the cable the screen works ,
any ideas ?
You could also try "ejecting" the device. That might put it in charge state and allow you to continue using the device.

I haven't noticed the "funky" screen on my NT, but have experienced it on smartphones in the past and it was associated with a noisy charger. Try using different chargers and see if the problem gets better or worse.
ah yes you have a valid point i have two NT's one for me and one for my gf hers blew a charger and we had to have B&N replace the usb port receptacle already , had it less than three weeks. I will try it with her usb cable and see what i get as they changed the whole assembly and if it does not occur with her new cable i will get them to exchange it before the 1st ..

Today i found out my SGS2 have problems charging the phone, not only that. i also have problems with USB file mode, and keis mode. and if the phone is turned off. i only once got it to charge without booting. else when i connect the USB it boot the OS.
What weird thing is, that ODIN works without problem every time!
The problem appeared after upgraded to Darky Rom KG6 with jkay mod. but don´t think it has anything to do with that.
I reflashed to a Stock KG6 (still same problem)
From OS restore to default, and format (still same problem)
tried to flash back to KE2 stock. an but on CWM, and clear battery stat, and system cache.
flashed backup with a KE2 Kernel (still had the same problem)
What i found out is that, when i disconnected the wall plug charger, the phone still was in a state of charging. and it don´t give the sound notify when attaching the USB. but when touch the USB cable it suddenly charge and give the sound. but it can also go in MTP mode. or start Voice recognize.
Could the be a faulty USB port on the phone, or can Battery State and kernel updates have something to do with this problem?
im now pretty sure this has something to do with the USB port. when i just spoke on the phone. it suddenly began to change between Car mode a normal.
i than tried an alternative why to deal with the problem. I tried with a hairdryer after taken out the battery, sim and sd card, and carefully heat the back of the phone.
for 5 hour there has not been any problem. both the desk dock, and wall charger is working.
got a dejavu from the xbox days and RROD.
I have the same issue. I think the USB port is faulty.
The phone reacts to different electrical resistor values on some pins of usb port that triggers car mode, desk mode, etc. So, somthing is faulty in the usb board that reports to the system that has something connected to it: charger, car dock, desk dock, usb jig, etc.
I can't find any solution on the forum, I tried with several roms and got nothing.
So... I'm waiting for a USB Jig to reset counter, back to stock rom and send it back to store for warranty
My problem seems to be fixed by using the hairdryer on the usb port. I think the problem appear from the why you hold the phone and if your hånd become sweaty. Because there are nothing to protection the usb port like the sgs1.

Yes it happening two times and it fixed it both times. So there is a pattern
hey guys... I posted something that worked for me...
see my post in the other thread here:
http://forum.xda-developers.com/showpost.php?p=16418825&postcount=25
I hope this could work for you too
Hi,
Please, be patient while reading this post, this is a looong explanation of the brick I am facing...
I recently was given a non working XTZ SGP311 and tried to get it back to life. As I have another one SGP311 (this one is perfectly working), I am able to check many things.
I read most of topics about XTZ unbrick but can't find any way to get it back working.
The problem is that I can't have any signal from usb (data or power). I use a genuine Sony USB cable and genuine Sony charging adapter (coming from the working SGP311). The led always stays off.
I tried the different combos as described (vol- and power ; vol+ and power ; vol+ and vol- and power) during 5, 10, 20, 30 seconds (yes, quite complete tests).
I did a cross check of batteries and inside usb connector ribbon (yes, had to open both tablets for that), the working tablet continues to work with the 2 parts coming from the faulty one (battery coming from dead tablet was 0% charged), so the problem is not on the side of the inside usb connector neither on the side of a supposed dead battery. The faulty tablet doesn't boot, even with a fully charged battery inside.
I luckily own a XTZ dock (SGPDS5) that allows to charge without using usb connector (it uses the 2 contacts located on the left side of the tablet). That's the only way to get something...
Soooo, when I put the bricked tablet on its dock, the red led flashes very slowy (say, 1 second off, 1 second on red, and so on).
When I press vol- and power, nothing happens (no matter 5/10/15/20/25 seconds).
When I press vol- and vol+ and power, idem.
When I press vol+ and power : I got the sequence blinks once white led / blinks 3 times white led (after that goes to slow red blinking about if I keep the keys pressed). So not completely dead.
If I unplug it from the dock right after the third white blink, plug the usb cable to the tablet, plug it to my laptop (with emma running, tried with pc companion too), and press vol-, then....nothing happens. Really nothing. No led lit. No detection of anything from the laptop (or device manager as well). It would have been the same if I would have kept it unplugged.
To sum it up, the only thing I can have is 1 or 3 white blinks after having plugged the SGP311 on its docks.
IMO, the trouble comes from a faulty component inside the tablet. Maybe the one that manages the connection from the usb ribbon plug. I checked the tiny plugs inside the tablet (once dismantled and back repacked too), all seems in order.
Your help is welcome !
This is similar to an issue I have it sounds like, you can still flash stock rom by holding power + volume till it blinks 3x then plug USB in and hold volume down immediately.
This gives flash mode, you can use flash tool to put stock rom on with this. The issue happens when it's acting like there's no OS it seems. Problem is mines doing this everytime I flash a custom rom, it's fine with stock aside from **** wifi
Thanks for your help. I tried that yesterday and it did not work.
This may be related to the way of reset I use (but I can't have any other).
As I can't get any white blinking led when connected by the tablet micro-usb port, the one and only way to get the 3 times white blinking led is when the XTZ is on its dock (SGP DS5, power connection only by lateral contacts).
What I tried yesterday was to get the 3 time white blinking led (vol+ and Power), then output the tablet off the dock and connect a usb cable to a laptop running Sony Emma (from micro usb tablet port to usb laptop).
Precision : I kept VOL- pressed when pluging usb cable to laptop.
No result at all. No detection (either Emma nor windows).
Any idea ?

Thanks for your advice, I appreciate.
But I swapped batteries from the working XTZ to the non-working one and put a (about) 60% charged battery into the bricked XTZ (both batteries are charging when set into the working XTZ). I will try anyway.
The problem is that the non working XTZ does not charge either through usb or through the dock. The only interest of the dock is that this is only situation where I can have the "triple white led blink" (but nothing more).
That's why I need the working XTZ for charging before doing anything with the non working one.
What I could try would be to connect the lateral contacts with wires to the dock in order to keep an access to the usb tablet micro port and connect it to a laptop.
But this may be hairy as this would give 2 ways for power (one by the dock and the other by the USB port), and may produce a short circuit...
Any XTZ power experts around ?

Well, not a real solution...
I bought a cheap xtz with broken screen and got its working motherboard and put it instead of the other one.I got the lte component too with its antenna and put it into the 1st xtz that was not supposed to have lte.
So now, on one side I have a xtz with faulty motherboard and broken screen, and on the other side a refurbished xtz with LTE !
I like very much this tablet. Very handy, easy to dismantle and easy to swap its components.
The only drawback is no more support for Sony.
Thank you for the answer
So, you are saying that if I replace the motherboard I can fix that ? I'm looking for motherboard on ebay and I found one for $28 usd + shihpping.
Thank you for answering and take care.

Yes. I think this should be good.
Don't care about the exact matching of the product code: as long as it'll be xtz, it'll be good (16 or 32 gb, with or without lte, and any region should match).
Did you opened it already ?
Yes, I opened 2 years ago cuz my son broke the power jack connector then I replaced that twice.
I'm also tech guy, I can replace that, but won't expend more than $50 for a new motherboard. I'm looking on ebay now.
Thank you

I have a problem with my LeMax 2. I was using google camera for some picture taking, and all of a sudden phone shuts down. I connected it to the charger, thinking that the battery is dead, but all I can see is backlight, without anything on the screen.
then I connected it to a computer, and there was a popup that said: "the last device you connected to this computer malfunctioned". it seems that USB cable is burnt out. I changed the USB cable, but the same error occurs.
The strange part is that i get notifications, I can locate the phone via Find my device, but i can't see anything on the screen, only i can see a backlight. PC does not recognize it, i tried Linux, win10, win7, USB OTG. i ordered a new Dock Connector Charging Port Flex Cable https://www.aliexpress.com/item/Original-New-Dock-Connector-Charging-Port-Flex-Cable-For-Letv-leEco-Le-Max2-Max-2-X820/32828762033.html?spm=a2g0s.9042311.0.0.116b4c4ds9GGuN, and changed it, but the problem persists.
i can only see backlight, the phone can be located, the notifications can be heard, but USB is only good for charging, even after replacing it.
Does anybody have some idea how to revive it?
Heyyo, hmm does tapping the power button allow the backlight to at least work? Please rest that in a dark room to see if you can notice the backlight.
If not? It could be a hardware issue... You could try heating the device with a heat gun and then using a suction cup or screen seperation tool and then check the connection of the screen to the device and ensure it is properly connected.
There could be other recommendations if someone else also has an idea
Yes, the backlight works. I opened phone, changed USB port and checked the screen connection. Firstly I thought that USB is fried due to some weird power surge when connecting the charger, but after changing the USB, it is the same.
The next thing that came to my mind is that USB connection on motherboard is fried. As I said, the phone charges up, but when connected to pc, it shows that device has malfunctioned. The screen has backlight, as far I can say it registers a touch, device finder can locate it, sound works...

hello,
my screen is broken (half lower part of screen is no sensitive responding)
I have tried a full restore but this don't work,
so now I have a full clean phone with the first install screen and no usb debug. (and screen don't want to rotate at this time)
I have acces to adb only under TWRP.
I would like to use this phone as 4G router.
I have done this https://forum.xda-developers.com/showthread.php?t=2786395
but still not managed adb working on booted phone.
any idea ?
If it's only the touchscreen which is no longer functioning on the lower half of your screen (and the full display is still functioning) then the easy solution is to connect a mouse or a USB touchpad to your phone. I have done this several times when I have dropped phones and damaged the touch screen. If you are going to use a regular mouse, then you will only need an adaptor to allow your mouse's USB socket to plug into a 'micro USB to USB' cable. I didn't need this, as I already had a USB touchpad which uses a micro-USB socket.

I have just tried to connect my USB keyboard and touchpad for the first time with my Z5 compact. Unlike with my Z3 compact, they didn't work straight away. However, you can get them working like this: (1) Settings>Device connection>USB Connectivity (2) plug in your device (3) Click on 'detect USB device.' This will take up to a minute. You will get a message saying 'USB Connected.' Then you can use your mouse/keyboard/whatever. Hopefully, your broken touchscreen will not prevent you from doing the above!

and I get a cursor !
so I had put usb debug, instal some air droid apk, and a tethering apk on the upper on my screen !
thanks all
Hi I have an LG Gpad X8.0 v520. It has a full size USB A port. I used to use a Kingston USB 64gb with it. But then one day suddenly it stopped working. The USB was not being detected nor any other device such as usb dongle for a wireless controller. They don't get detected even when I connect using the charging micro-B port with an OTG converter. Sometimes it works perfectly and then it works for like a day maybe two then stops working again. I have no idea what triggers it but the not working times are much more than the working times. My suspicion is that it has something to do with charging the device. Perhaps media is disabled during charging and it doesn't get reenabled. But I don't have the expertise to diagnose the problem I was hoping someone could help. I have already tried restarting every time and the USB devices all work perfectly on their own.
Any help or advice would be greatly appreciated.
I am not sure if your device has a mechanical issue ( contacts or pins inside connector? ) or only software.
i have a handful of V521's and some are fast when detecting USB , other take a min or two. whenever the STOCK rom/firmware hangs or does not populate with a new usb device, i power down the device after plugging it into charger. ( this isn't fast..) when its completely in stand-by , waiting to be turned on, wait for the battery icon to pop up on the screen ( charging level / status ). the battery icon that pop's up indicates a hardware controlled charging status. insert your USB and then power ON your tablet. (note: A 1tb SSD - it takes about 9 minutes to populate under LG's file explorer after this) This should work, but from this point on, use the EJECT option ( software ) before removing the device.
-i can confirm on 4 separate V521's that if the battery is 20% or LESS, USB devices won't always work. i never found the perfect tablet charge level, but 80% seems to have no issues for me.
The FACTORY rom only likes certain partition tables, so if your USB drive or thumb drive gets messed up, check it in a linux device. (it ALSO doesn't seem to like more than 2 partitions PER usb device)
-the V521 will see a 4TB SATA SSD in a usb enclosure, but don't expect it to instantly appear.
i use a dedicated LG-v521 tablet , to transfer files wirelessly with my SHIELD TV's.
-last note for ANYONE having issues, try a WOODEN TOOTHPICK if the USB connectors are pushed down or need re-bending. I like to smash a toothpick end with a flat hammer, dip the toothpick in some super thin superglue (CA) , let it dry, and it becomes the perfect contact adjustment tool.
-DE-OX-IT contact cleaner ALSO works wonders, just kind of pricey for a one time fix. ( this stuff is amazing, but ALWAYS WIPE IT OFF after using it, otherwise it continues to remove oxidation and makes a mess )
-there is a current limit set for the USB port on this tablet, and if the USB you try, bumps it or exceeds it, i'll start the process over again with restrictions ( lower power levels ) until a valid handshake.

I am having this issue as well. No noticeable physical damage. I factory reset the device too. The usb provides power just fine. But there is no data exchange. I am using a CarPlay dongle with it and it worked all day yesterday then it suddenly didn’t work. At first I thought it was because I drained the battery to 20%. So I charged it and the issue still persists. Any ideas?

Tried multiple dongles too. Tired usb thumb drives and they don’t detect either.
- does the tablet have WIFI/CELL signal ?
- did you try power cycling with and then WITHOUT the USB device inserted ?
-is the battery near the end of life, IE: old lipo EVEN IF CHARGED will cause nightmares..( changed 7 tablets batteries over weird issues )
- You confirm the USB port still provides power when needed ? (ill post a pic)
Stock ROM? ROOTED?
-whatever device you plug in, does the STOCK FILE EXPLORER show anything ?
-i turned off AUDIO ROUTING USB under DEV settings, not sure if this matters ?
-Conflicting APPS trying to all see the same port ? ( ES FILE EXPLORER gave me issues )
-its possible if you plugged in a USB DEVICE that pulled too much power, the regulating IC failed?
-ODD one here, but did you wait a bit, to see if it populated ?
below is a 8TB drive in a cheap china case, works great, just need to wait about 10 mins for it to populate.
(i use a dedicated V521 for compressing files , then moving them to HARD DRIVES)
- not sure what MICRO SD card everyone uses, but i personaly like the SANSDISK EXTREME PRO ( BLACK RED ) just wish they weren't so expensive. - the V521 will move files from the MICRO SD to HDD at about 50-70MBS
