Hello, I have been turning mad lately since my Optimus 3D began acting weird once I connected it to my PC to transfer large amounts of data in USB MASS STORAGE mode.
In the beginning, the transfer was ok and connection didn't show any problem. However, at a given (arbitrary) point, it just connected and disconnected by itself several times in just few seconds.
I thought it was the usb cable, so I changed it, but that didn't fixed it. Then I tried it with several other computers, and that happened randomly on all of them.
Then I thought it could be the micro-usb connector being damage, but as I closely analysed it in the computer side, I found that the phone was connecting ok, but was recognised the wrong way. (drivers were ok, as I reinstalled everything several times)
In fact, the LG update recognised the phone's model and connection. It simply didn't worked as a mass storage usb device.
I spent hours searching the web for answers about this issue, but the only thing I could found was one guy telling to remove the battery for 10 minutes in order really reset the phone's usb mode.
I did it and it worked! HOWEVER, the issue reapeared quickly once I connected the phone to the PC via USB. (it took several minutes to happen, but happened)
I finally found this forum and read a lot of complaints about LG phones.
However, it seemed to be a software error, not a hardware one. Wich was good news.
I was thinking to send the phone to LG for repair, but I had little hope they would even check such an arbitrary issue with usb connection and I thought they would simply say it's my computers fault, so I kept searching.
I finally found a similar issues with Galaxy S2 on the forums, and someone fixed it accessing the "PhoneUtil" hidden app in that phone.
This app don't exist in LG phones, but there IS a hidden menu to fix this, but you will have to install a free shortcut creator app form the market place in order to access it:
- download "ANY CUT" from the market place
- run it and create a NEW shortcut
- select ACTIVITY
- scroll down and tap on: com.lge.hiddenmenu.port_setting.PortSetting
- give the shortcut a short name like "Port Setting"
now you have created a new shortcut in your home screen (somewhere)
Once you tap on it, a menu will pop and let you choose the type of connection to be used by the USB port.
By default, "NO RETENTION" is selected.
If you want to force the phone to use the usb connection for data transfer with your PC, then select AP USB
(if you check the "retain AP USB after reboot" it will freeze your phone and you will have to long press the power button to shut it down, but it will actually work and will be set this way until you change it again)
Voila! That fixed my LG P920 Optimus 3D USB transfering issues.
If you need to make a software upgrade at some point instead of using it for USB transfer, just change the setting to "NO RETENTION" again and check the "reatin after reboot" option.
I just wanted to share this, as I found no fix for my problem in the net and I think this should be happening to someone else.
Feedback is very welcome! (even needed, just in case this is braking something)
By the way, it's a good idea to activate the "Debugging mode for USB" in settings/applications since it seems to make a more robust conection with the phone for mass storage transfer.
As why this entire issue is happening, it seems the USB conection can handle multiple transfer modes. One of those is USB Mass Storage mode (like every pendrive out there) but the other one is a LG propietary comunication mode that I suppose was done in order to have full access to the phone firmware through the computer.
The bug appears in the moment when the phone have to decide if it should engage on mode or the other.
I have noticed (since I forced the port setting to AP USB) that the phones screen will turn itself on randomly once connected and that it don't stay active even if you specifically check that option in the development menu.
I suppose the original bug is still there in someway, but at least it will not ruin the data transfers.
Ok, just in case you don't want / can't make the shortcut for the hidden menu, you can use this method to access the full hidden menu right out of the box without any external app:
push the button to make a call,
now enter the number:
3845#*920#
This will redirect you to the full hidden menu. Once there, you can go to the PORT SETTINGS menu and set it to AP USB.
And if you want to upgrade with the LG software, you must set this to AP USB and make it stay. Then when you are upgrading, you must stay vigilant and press (and keep pressed) the volume up button in the moment it reboot the phone (or before it reboots, just to be sure)
This way, a white screen with red text "factory upload" will show and upgrades will have no problems.
(this mode normally only happens when you press the volume up button with the phone off, and then connect it to the usb port and there is an LG software commanding the phone via usb)

Hi.
I'm using the TP for quite some time now without too much hassle, but one thing annoys me.
For a few days the selection menu is gone when you connect your TP to USB. Normally it pops up a screen to select ActiveSync, FlashDrive or Internet Sharing mode.
Now, it just uses the last selection and I've never switched on the "Don't ask me again" button.
I've found the USB to PC settings which do about the same, but even if I switch on "Ask about connection type when I connect" it just doesn't. And then, I like the TouchFLO popup better.
Anyone a suggestion on how to get the selection screen back?
Thanks a bunch!
If you go to parameters, connexion, Usb parameters, you need to activate :
- Activesync (synchronise with Outlook)
- Activate the functionnality advanced netwerk
- Ask the type of connexion when connected
Same here.
im too afraid to tick the dont ask again box insase i cant find it again. it does sometimes not appear though
Perhaps the USB cable you use is not optimal.
Do you try also with the original one??
As strange as the menu disappeared, it was there again yesterday all of a sudden.
It appears "fixed" but I must agree, it doesn't show every time... Definately...
I seem to be encountering a slight inconsistency in regards to mounting the phone unto my windows 7 box.
Essentially what happens is this: I plug my phone into the computer and the little dialogue box pops up onto my phone (Kies, Mass Storage, PC Internet etc). I push "Mass Storage" and ideally what is supposed to happen is that the phone mounts onto windows.
Unfortunately it doesn't seem to mount.
What does happen is that the drive letter shows up, usually F:\ but it's not mounted.
When I pull down the settings menu, it says that USB is connected and that's about all.
I will unplug my phone, replug it back in again invoking the USB menu only this time, I will hit the "Home/House" button, or the "Back" button which will take me to the home screen.
I will drag down the settings menu like before, only this time under the USB box, when pressed it gives me the option to mount which if pressed, mounts the phone and gives me the ability to access it.
So whats the problem? It's very inconsistent. It doesn't always do that. Sometimes I have to unplug and replug my phone in to invoke the mount USB option.
My questions are these: Is anyone else having the same issue? Am I just not using this correctly? Is there any simple way to just "mount usb"? An app or perhaps a function that I'm not seeing?
Thanks!
Out of box, you always need to manually mount the drives once connected. It does not auto-mount. I was told there is an app that can auto-mount for you.
If you're running 2.1 firmware, the mount option is in notification area. If you're running 2.2 firmware, there will be a USB mass storage screen where you can click on the mount button.
That's fine manually mounting the drive, my question is: How do I mount the drive if there is no way (that I can find) that gives me the option except for the seemingly random "mount USB" box that comes up 7/10 times in the drop down settings dialogue?
It comes up 100% for me.
Sent from my SAMSUNG-SGH-I897 using XDA App
Could you describe the process in which you do? Perhaps I am doing something wrong in the procedure.
It comes up randomly for me too. I didn't have this problem on 2.1 Eclair. It isn't anything crippling, but it is annoying. It happens half the time for me.
I should mention too, that i am running Eclair 2.1.

Nothing special. Plug in the USB cable and go to notification area to mount the USB drives. I do configure my phone to prompt for USB mode everytime I connect.
You may want to try different USB ports on your PC.
My buddy has a Captivate that mounts fine in mass storage mode, except it brings up the windows dialog box saying "no disk in drive: Retry?" every time. It doesn't fail to work or anything, the sd card is accessible without any problems. It just throws up that dialog every time. It's rather annoying. Anyone seen this before?
Change it to "ask" instead of be "Mass storage" every time. I bet it'll work.
You might find that then changing it back makes it work again. Otherwise just leave it at "ask".
i never had it work in ask on connection mode, and it annoyingly always wants to launch kies no matter what setting i use even after messing with the setting in windows. i have more success with the phone in debugging mode and mounting from the notification menu. it may be that the other options wont work in debugging mode and the computer isn't trying to mount it as an mtp device because of kies.
if i was still on eclair id test it to make sure, my memory gets alittle fuzzy. froyo seems to work better in that area.
Your saying you just get "USB connected" instead of the norm "USB connected, select here to copy files to/from your computer" in the blind menu?
Happens to me as well. Usually if I reboot both the computer and phone I'm good to go. I didn't have the problem on 2.1.
The method that has never failed for me is to turn on USB debugging. Then when I connect the USB, I always get the second notification in the pulldown screen with the text "Select to copy files...". Clicking that brings up a box to mount (or some less vague word choice in 2.2), and accepting that always works to show the 2 drives on my computer.
USB debugging completely circumvents the USB settings panel. You can either use one or the other, not both. I have always found the USB debugging approach to be totally reliable. Right now on Cog2.2 Beta6 both approaches work fine, but I usually leave USB debugging activated for other reasons so I use that method by default.
Hello.
Short story: my phone was a little wet and i have some issues with it, mostly i want to get a mass storage to get working. (cant root)
Basically at first the phone didn't even want to charge, when i connected it to the PC windows was giving me an error that the device cannot be recognized, and couldn't install the drivers. (i had Kies installed)
I dried it completely, now the phone turns on without any problem, when i connect it to the pc the phone is recognizing connection (i hear sound + the button backlights are firing up for a sec)
Homever, windows is not detecting any USB device at all, and in about phone/info it says the phone is connected to the AC instead of USB.
When i connect it with USB there is no dropdown in notification to choose from charging, storage etc.
There is also manual usb storage mounting under settings/communication/usb settings , when i'm trying to mount here it just says to connect the phone with usb cable (not detecting connection, homever the backlight + sound is here after connecting, and it's charging)
I tried connecting it with usb debugging on/off even tried to fiddle with in service menu (*#7284#) but nothing.
And since i cannot get the usb storage working basically i cannot flash anything or root it.
Also the USB cable is not a Samsung but an HTC one, could this be a problem? (people in different thread said those cables are the same so it shouldnt be a problem, same amperage, same stick etc.)
Even tried to install MountUSB Widget from market, but it doesn't work when im trying to start the app it's force closing, when i make widget on desktop and press it the phone just vibrate for 1 sec and nothing happens.
When i connect phone with Kies AIR and it works, i mean it shows the storage information, also recognize the phone model correctly, how much free space i have on internal and on SD card but i cannot click "show in explorer" it's greyed out.
Any experts out there could help me? :crying:
Just a blind guess, try a USB cable which supports your device. If it doesn't help, I'm afraid it's a hardware problem and you will have to consult some hardware expert.
I'm helping a friend who needs backup of her broken phone for an upcoming court case.
I need to extract all photos (camera, snapchat etc) and text messages (sms/mms).
The phone seems to be working other than the screen and touch controls.
Replacing/repairing the screen isn't an option as we both have minimal funds, and my friend has a new phone already)
i have "access" to the phone, but neither USB Debughing nor MTP is enabled so i cannot access any files.
I'm able to unlock it with a keyboard connected (i hear the little unlock click after entering the pin, and the "turn off screen" click when i press the power button.) But i have to navigate blindly, and any guide i find seems arbitrary how to get to settings, it says to press win+n (same as pulling down the quick settings menu from home) and press tab an arbitrary number of times to get to the settings gear in the corner. i tried doing this on my own working note 10 plus with the external keyboard, but i see it scrolls through every notification, so unless you know the number of notifications, hitting the gear is just pure luck.
I have also tried hooking up a usb-c to hdmi dongle (which works and starts dex on my n10+) but it says no signal on the A80, so external monitor seems out of the question.
Is there a consistent way to enter settings, or any way to enable the following settings:
* enable voice assistant (accessibility settings so i can hear where i am and navigate using voice/sound)
* enable USB MTP (or similar so i atleast can access files from a computer)
* enable USB debugging (to use ADB to screenmirror and/or etc)
* alternatively clear notifications so entering settings should become consistant with number of keypresses
I have tried some apps like dr fone but it doesnt support backup from this model, and any other settings wants to wipe the phone.
I have tried holding both volume buttons to enable google voice assist, but also unsure if this ever worked
The phone is not on wifi and i am not 100% sure if wifi is enabled at the moment, nor if it has the current wifi password my friend uses, but i can try do do things from there if internet access will help.
I dont think google now nor bixby (if this phone has that) is enabled as i dont get any reply or voice ding while pressing the win key (home button normally on working android)
I think i can enter recovery and download modes, i got COM5 on odin, but I'm unsure if i ever get into recovery menu.. but even then, is there any custom recovery firmware that will enable usb mtp access at all for this device?
Also, I'm not able to have a computer connected at the same time as a keyboard as I'm using a wired keyboard with OTG adapter.
Tl;dr:
Have:
* A80 with broken unresponsive screen.
* Have access blindly through otg keyboard
Need:
* Need to enable mtp and/or usb debug (alt. Voice assist)
* Need consistent way to access settings
Both MUST be done using only wired otg keyboard.
Tried:
* Hdmi out (no signal)
* computer recovery software (no dice)
* having computer and keyboard connected simultaneously (keyboard works, pc doesnt recognize, could be dongle)
Hope someone can help me (us) fast.

have you been able to verify that the MTP device actually works with other phones?
those things can be picky

USB MTP is just file tranfer?
F.ex. if i use smartswitch on pc, it first tells me to unlock the phone, if i unlock the phone with the otg keyboard and reconnect it it says i cannot tranfer files because MTP is not enabled in settings.

sorry man, i meant MHL adapter.
As far as i found out, A8 does not support MHL/HDMI out..
guess ill spend the weekend to try to get voice assist working by blind trail and error :/
If anyone could provide screenshots of the settings menu and/or recovery menu (and if its possible to enter without touching the screen, and if so how) that would be greatly appreciated.
The phone should be mostly completely stock set up, but home icons might have moved and menu icons might not be in the same place, but i think the pull down menu should be the same as any stock setup, so a screenshot of that would be nice too
Hi
As far as Android goes, by unlocking the phone and plugging it into a computer then you should be able to view the files on the phone from the PC like any USB drive. What you can also do is use Samsung Smart Switch and do a backup of the phone on a PC as this will be able to pull all text messages, photos, etc into a backup folder. Then you can restore any part of that backup on another Samsung phone, including messages.
There may be a few things that will not transfer over. As far as viewing the photos and other files, you can navigate to the backup folder on the PC and check everything there. This is all provided that the phone actually works and is unlocked.

As stated in my original post, usb-MTP (file transfer) is not enabled by default, and my friend never connected the phone to a computer, so i have to enable it to be able to access anything.
The phone connects and seems to work fine except the display, smart switch says to enable mtp pn the phone to transfer files after i unlock it, so my problem is activating talkback so i have aural navigation help so i can turn on usb/mtp for file transfer(and hopefully adb) or to turn on usb directly, but i think talckback is the highest priority as it will help me navigate the phone and be sure of where i am, an accidental keypress on can ruin a long sequence and i would have to start again from scratch as i cannot know if im in the same location.
Hi.
Any update on this? I have exactly the same problem and no solution so far...
Thanks
For some reason I can't connect my Pixel 4a to my PC with a USB C - USB A cable (or USB A - USB C, not sure what the official name is) , even though it worked fine on my previous phone.
Included with the phone is a USB C - USB A adapter, but I see no use for it unless you have a special USB A cable which I don't.
My motherboard does have a USB C slot on it and it does read my phone when I plug it in that way but for some weird reason it's really loose and doesn't stay connected unless I keep physical pressure on it.
I'm not going to update to Android 11 until the November update because I've heard the current build has a few bugs, but does anyone know if Android 11 fixed the USB C - USB A issue?
Have you made sure to switch to file transfer mode? It defaults to 'no transfer' mode when I plug into my laptop.
Most likely you need to toggle the phone connection settings to data transfer, originally it will be set to charge only I think.

I had this issue too. Windows file explorer would just crash after one or two files and stop transfer, no matter the size and type. (Yes I had file transfer selected on my phone ?)
Then windows update gave me a driver called "Google Inc. - Other Hardware - Kedacom KDB Composite Interface". I also updated to the newest firmware on the phone. No idea which of these did the trick or if it was the combo. However. Smooth sailing now ??
Hope this helps
(If windows update refuses to give you the driver, you can get it from Microsoft's update catalogue online. A Google search will do)
Ok it's completely messed up. When I search for USB settings it doesn't let me change anything at all, even though when I first got the phone I could and I changed it to transfer files. EDIT: No actually the setting that I changed was a developer option called "Default USB configuration" which I changed to transfer files but that still did nothing.
I just plugged in my phone and looked for the USB setting in the notification area but it wasn't there, but I noticed an option called "manage"
I went in there and noticed this. (see attachments) it's locked to be off and I can't change it. Very odd.

You're in notification settings. Try short tapping rather than long tapping to get the menu to pop up allowing you to select data transfer.
Changing default USB settings in developer options doesn't work for me either.

My point is that the notification that normally comes up when you plug in your phone to a computer to change to data transfer, charge only ect ect isn't even coming up because the firmware is stopping that notification from coming up altogether and I can't change it so it does.

Almost certainly a cable or host port issue. Swap cables and see what happens. Same for hosts/host ports. You're not going to have toggling options if the phone does not 'see' all expected lines/pins.
I had the same issue and changed to a different cord to fix the problem.
You have an non certified cable it seems, I've confirmed this pixel 4a works with only certain cables for usb transfer, also the usb a to c cable you have will not charge the device as well.
Get a cable from know manufacturers like Samsung, it worked for me.
Yeah turns out it was a cable. Strange how my cable worked with my old phone but not with the Pixel 4a
Had this issue with my new 4a just now. Cable was fine, even used the new cable that comes with it using a Usb C to Usb A adapter. Nothing worked. Upon opening Device Manager I found a new device called 'Kedacom USB Device'. After trying random things, I decided to uninstall the current drivers by right clicking on it and clicking 'Uninstall device'. Suddenly the phone connected, and even showed the adb prompt.
So for anyone still facing this issue, hopefully this solution might help
