[Q] Help! LG E400 USB problems - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hi, I have been rooting and ROM-ing my LG E400 for a while now, and I have come across a problem.
It seems I have accidentally deleted my usb driver on my phone, so when I connect my phone to a computer it charges, but i cannot access the phone through the computer in any way.
Can anyone help???????

I think you can select what your phone has to do when connected to an USB somewhere in the settings. Make sure to let your phone connect as a media device, because that way it'll give you access to its internal and external SD card. Also, if you have a PIN/password lock screen, you need to unlock your phone after you plug it into the USB otherwise it won't give you access.

I have searched every crook of my phone but there are no usb options available. They used to always pop up when I plugged in the usb, but they are unaccessable to me. When I plug it into a computer, the computer does not even recognise it as a connected device. This has happened with every computer i have connected it to.....

Computer problems

My computer will say the driver's are installed, but when I go under my computer to move files, there is no drive listed for my phone. Whats going on here. Using a new hp computer with windows 7. Any help here would be nice.
I have also check the device manager, It is listing it as a t-mobile slide, bla bla bla so I un-installed and re-installed, still no luck, How or what am I doing wrong that the computer isn't listing this as a drive so I can move files?
when you plug phone in, a notification should apear on phone, pull down top bar and see what the USB symbol says next to it, if it says anything other than disk drive then go to settings>connect to pc>disk drive and then hit done
I do not have a usb thing pop up n my phone n the setting are right under the phone
it should be a notification in the notification bar, if you are not getting the notification then you may have a bad port on the computer, is the phone charging when you plug it in?
Try replacing the USB cable if you plug it in and charge light doesn't turn on.
nope, tryed different ports, all are reconizing that the phone is plugged in n the phone charges
Ok, I'm going to try a different computer, I tryed here at work, the computer started installing but I needed admin rights to install hardware so I guess I will try later
Stupid question, but have you tried: from the home screen, if you go to Menu > Settings > Connect to PC, Default connection type, try setting it to Disk drive...
Yes and I have tryed turning it to sync with the program I downloaded from htc, nothing. Now when I plugged it in last night, I noticed that I plugged it into the sata port but it still regonized the phone, deleted the driver n re installed by actually using the usb port but still nothing. So I just tryed my older laptop n it installed the driver, said t mobile slide, phone was chargiing but I still ddnt have the usb pop up on my phone.
I am starting to think somthing is wrong with the phone
Ok this is weird. I used a older laptop with xp n everything works fine. What should I do or download for win 7 to work properly

Connecting to pc

Just got my samsung focus and also just downloaded the zune software. Im having a problem getting the music to go to my phone.
I have ares music downloader where all my music is, my brother sent all his music to itunes, and i am sending the music from ares to zune. When he sends his music to itunes to his iphone it goes through pefectly fine.
When i send my music from ares to zune then to my phone it says Cant purchase due to a temporary service error. Please try again later. Why is it saying this, is it trying to make me purchase music i have already payed for again??
Ok I've been using a Zune since the first Zune 30 Gb came out so here's what you need to check.
1) Make sure your zune software is pointing to your music libraries by going into Settings/Software/Collection there you will be able to manage what Music, Video, Pictures, and Podcast libraries you want the software to see. Now the other thing you might want to look at is your phone's sync settings. I have everything set to "Items I choose" because I don't want everything syncing over. In settings select phone. There you can choose how and what to sync.
2) now to get music on your phone, if your libraries are correct all your music should show up in the collection tab which is located at the top with quickplay, marketplace, and social. Once there you can select and drag and drop the music you want on to your phone. The other way which I find easier, is to make a playlist of the music you like then drag and drop the playlist to your phone. Then the music will be synced over per what's on your playlist.
Hope this helps.
Well another thing is when i go to zune software its not even finding the phone anymore, its saying please connect device
How are you connecting your phone? USB or Wifi?

It should start the zune software when you hook it up using usb, I don't do the wifi sync because I rather have it charging while syncing. If not you might have to un install and re install the zune software.

Wi-fi sync requires that your phone is charging. Instead of plugging into the computer, you're plugging it into the wall adapter.
Im plugging it in with the usb connector straight into the computer

Ok, then have you tried any of the following?
1) Restart your phone
2) Restart your computer
3) Try plugging the usb cable into a different USB port

If it has to charge while using wifi then why use it, you need your computer anyways to sync it. lol
things to try:
Unlock your phone
If Screen Lock is enabled on your phone and this is the first time you have connected your phone to your computer, or if you are connecting your phone as a guest to a new computer, unlock your phone first. To do this, turn your phone on and then flick your finger upward on your phone's screen until you can see the keypad for entering your password. Then enter your password.
Name and update your phone
If this is the first time connecting your phone, you must first give it a name and check for updates after you are prompted. If you click Cancel you will have to disconnect and reconnect your phone.
Restart your computer
Disconnect your phone from your PC, restart your computer, and then reconnect your phone to your computer using the USB cable that came with your phone.
Restartyour phone
Press and hold the Power button for 5 seconds until the message "Goodbye!" appears. Press the Power button to turn the phone on again.
Note If the phone does not turn off normally, remove and then reinsert the battery.
Try another USB port
Connect your phone to a USB port on the back of your computer. Do not use a USB hub.
Note Be sure to use the USB cable that came with your phone.
Examine Windows Device Manager
Click Start, right-click Computer, and then click Properties.
Click Device Manager.
Click the root computer icon at the top of the list and then click Scan for hardware changes under the Action menu. Windows Phone 7 should be listed under Portable Devices. If Windows Phone 7 was installed incorrectly, it may be listed with a yellow exclamation mark (!). Or, it may be listed under Other Devices as a USB device or an unknown device.
Double-click the phone icon and then click the Driver tab. The current version of the driver that is installed should be 4.7.965.0.
Update your driver
If Windows Device Manager indicates a device problem or if the driver version of Windows Phone 7 that is installed is not the current version, you must update the driver. To do this, follow these steps:
On the Driver tab, click Uninstall.
If it is displayed, click to select Delete the driver software for this device and then click OK.
Click the root computer icon, and then click Scan for hardware changes on the Action menu.
Open Portable Devices, double-click your Windows Phone 7, and then click the Driver tab.
Click Update Driver.
Click Browse my computer for driver software.
Click Browse, locate the Program Files/Zune/Drivers folder on your computer, and then click OK.
Click Next and if you are prompted, click Install.
After the driver installation is complete, click Close two times to exit the Device Manager. If you are prompted to do so, restart your computer.
If all that doesn't work, I would un-install and re-install the Zune software.
well i got it to work but i had to get the zune pass to do it. Just using the trial version right now.
Seems very silly though i already have all my music on my computer from ares downloader that i already pay for, i send the music to zune just fine. I think its trying to make me buy my music twice which is pretty dumb i must say

Because some people would prefer to not to have their phone attached to their computer. Perhaps someone wants to leave their phone with their keys and stuff so he/she can grab all of their stuff they need to leave their house at once.
Or, in my case, plugging my phone into the computer can lead to all of the USB devices plugged directly into my motherboard losing power. Yes, that's a very niche issue, but it's still a use-case that makes WiFi Sync useful.
That would mean your powersupply isn't giving the board enough power then, or go with a powered hub route. Don't know if it's me, but I notice the phone taking longer to charge when the wifi and bluetooth are on.

[Q] PC Will Not Recognize My Phone Over USB

Hi everyone,
This is my first post about my Note 4, and I'm really frustrated.
All I wanted to do was transfer some music to the SD card on my phone, and I've just wasted the entire evening and have nothing to show for it.
I'm running Windows 8.1 on my PC and Android 5.0.1 on my Verizon phone. When I connect via USB, a popup in the system tray says that it has identified a Samsung File-Stor Gadget USB Device and assigns it drive letter F:.
However, almost instantly, Windows decides that my phone is a modem! USB Safely Remove and Device Manager both call it a Samsung Mobile USB Modem, and Explorer does not show a drive F:.
The Notification dropdown displays "Connected as a media device", and when I tap on it, I can see that "USB computer connection set to Media device (MTP)" is checked.
I installed the latest version of Samsung Kies on my PC and ran it, but it fails to connect to the phone.
Can anybody tell me what's going on? Thanks!
P.S. Ironically enough, even though I can't do anything, I can't stop the device because adb.exe has the connection locked!
Card reader is less hassle. Cables as you know are unstable at times.
I would try going into Device Manager (or maybe Devices and Printers) in the Control panel, right clicking your device and uninstalling it.
Reboot and let Windows detect the device again when your reconnect the phone.

Good idea, but I checked and it wasn't there. When I connect, a new Modems entry is created in Device Manager, but when I disconnect it disappears.
I might have to go w7excursion's route. Thank you both for your suggestions.

A problem with mtp enabling in EMUI 3.1

Hi everyone,
My mother is the owner of a Huawei P8. She used to use the phone as a second hard disk but lately she touched something (and she does not remember what) and the phone is set to charge only when connected to the PC.
At the moment when the phone is connected the computer neither the computer or the phone seem to recognize each other. I went through almost all the settings but couldn't find ANYTHING on how to make the computer react to the phone. Moreover in the developer options of the phone USB debugging is greyed out, totally inaccessible.
If possible I would like NOT to have to root the phone or do strange installations. Online the only kind of answer I found was that I have to do a hard reset of the phone. Is it true?
Thank you for your help and patience.
Best regards,
Vanja A. Mariani C .
When you connect the P8 to the computer, it will appear in the notification bar a mention to the USB connection.
It has a blue USB icon and it shows "Photos", "Files" and "USB unit" (or somewhat like that). There is an small text there that states "if you don't select any mode, the device will only charge". Probably your mother put accidentally her finger over the "Files" option and this notification works like a On/Off switch .
If you want to use it as an USB drive, just put your finger over "USB unit". This mode is like plugging a pendrive to your computer (apps on SD
card will force close). Alternatively, you can put your finger over "files", and the SD card will mount in MTP mode (slower, but doesn't close the apps).
See my screenshot (it's in spanish, but you will quickly see what I mean).
Cheers.

If im correct the solution is:
Deactivate Developer options and then reactivate it again.
Then the USB debugging option should work again.

PC wont recognize device for file transfer

Just recently i tried to transfer for the first time, some wallpapers to my phone, and when i plug in the usb, the phone starts to charge normally but i cannot figure out why i cant transfer files from pc to phone or vice versa.
When i plug it in, it gives me the option to select what to "Use USB for", but when i select either MTP (file transfers) or PTP (transfer photos or files), nothing happens. I cannot browse the phone to pick anything at all.
When i go to device manager on PC i see under Portable devices the name of my phone (Moto G4 Play) but it has an exclamation point next to it. I have tried to uninstall and re-install or even update the driver but it will remain this way (if i click its propierties it tells me "This Device cannot start. Code 10"
Is there anything else i can do either on my phone or pc to make this work?
Other info:
Already downloaded motorola device manager to see if it would help but nope.
My PC OS is windows xp (yeah, i know... :laugh
My PC OS is windows xp

That probably explains everything
I don't think there are compatible drivers for Windows XP..
Long term support for WinXP ended three whole years ago. Though what I noticed with CM and Lineage is that the first time the phone is set up, it won't enable MTP even if checked. You have to reboot the phone and then MTP will actually enable properly.
Also, it may happen with 3rd party cables too. I myself faced this issue with Boat Indestructible cable, then I used the original cable that came with phone and successfully done it. But I still can't understand, how that cable can transfer data to/from other phones....
Just another bit of info:
Today while trying to make it work, i updated the driver from the Device Manager again and somehow i could access the phone as intended.
The problem is that after a few seconds, the window closes on its own! Then i have to redo the whole process and It gives me access again but every time, after a few seconds, the browsing window closes on its own!
I have tried with other cables and no dice, tried also rebooting phone and pc and also tried plugging it to all available usb ports. Any other tip or method i can try?
Try another pc to discard things (so you know if it's the pc or the phone)
