Phone will not be detected during fastboot - LG K7 Questions & Answers

My device(LG K7 MetroPCS) running 5.1.1 is unable to be detected by my PC using ADB and Fastboot. I am attempting to unlock the bootloader. I have correctly installed ADB and have installed the LG drivers for my device, my phone is easily read when turned on and off and the correct google USB drivers are installed as well. For good measure i installed LG Bridge, Java SE and Microsoft .NET 4 Framework. I have used many different means of ADB and they all work fine,for some reason this device will not connect while in fast boot, when i plug it in during FB, the PC give me 4 quick error tones as if a driver is missing, anyone know what could cause this issue?

goto device manager and look for any errors as you plug your phone in. if there is any with a yellow triangle right click and choose update driver. it will then search for the drivers and install them.

[Q] Setting up adb without installing Moto software

I'd like to simply connect the USB cable and connect to the device via ADB from my win7 x64 pc..
I've installed the latest set of USB drivers from the android SDK but am failing to update the driver since it says its not compatible with a windows x64 based system.
Anyone have any luck?

You need to install the Motorola drivers...that's the same for every phone. You need the drivers for the model phone you're trying to connect to.

Ok thanks - was thinking i could use the generic one from the SDK but guess i can't. Thanks.
EDIT: confirmed that using the Motorola ones do the trick - and i can connect to the device using ADB without going into Media sync or Phone portal mode.
if you want to be even more fancy, install adbwireless on the phone, and you can do all the adb stuff over wifi.
Unfortunately doesn't work in the workplace for me

ADB failing to install?

So I just got an Atrix and im trying to root it, however when I plug it in, after setting USB Mode to None and turning on the USB Debug, ADB drivers fail to install. It shows up in my device manager with a ! ontop of the icon, and windows tells me it cant find a driver. I manually downloaded the drivers but that still didnt help, my phone isnt making a connection of the bridge. Ive wiped everything everything motorola related, reinstalled the drivers manually, reinstalled the ADB driver manually, rebooted about 10 times and now im absolutely stuck.
Has anyone run into this before? Im going to try plugging the phone into my work computer today, but id like to be able to get this working on my home computer. I followed the guide thats available out there that tells you to run the driver installer and delete all the files it shows, and that didnt help either. Im on Windows 7 but i also have a laptop with Ubuntu available, however i couldnt find a rooting guide for linux so im not sure if that will help.

I got it sorted. Installed the ADB driver manually (choosing the regular adb driver NOT the composite driver) and then ran super one click to start the ADB service. Then once the phone was connected, ran aroot and it worked.

Problems with MTP USB Device

I plug my phone into a USB port.
The first time I did so, an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
The LG United Drivers are installed onto my computer great.
But then an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
My computer attempts to install MTP USB Driver, but fails. According to Windows, the device is unplugged.
The AutoPlay window reappears. Repeat from the beginning of the paragraph.
What have I done to deserve such trouble, LG?!?!
Apparently the drivers installed directly from phone are not enough. In any case, I was observing similar behaviour *until* I installed LG PC Suite (which you should have been prompted to do too). It's stupid, it sucks but again, it's LG.
Install the LG drivers first. After that, when you plug your phone, it will be recognised as an mtp device.
Have you got Windows Media Player installed?

I do. Same problems.
Plug the phone, go to device manager in windows and uninstall the driver for the phone( or whatever shows up with the yellow triangle). Then unplug the phone and connect it back again. It should work. If not, uninstall the lg drivers and clean every trace of them and start from the begining.

Tried uninstalling the LG U2 USB Driver, then disconnected and reconnected phone. Same problem. LG U2 USB Driver was installed but MTP USB still shows up as unplugged.
Then uninstalled LG PC Suite and LG United Mobile Driver, reinstalled LG PC Suite and reconnected phone. Problem still occurs. I run LGAutoRun.exe and United Mobile Drivers are installed. Same problem. MTP USB shows up as "device unplugged" and phone keeps disconnecting and reconnecting to computer, saying drivers were not properly installed due to MTP USB being unplugged.
Interesting to note the phone is listed as a CD-ROM drive.

Install the software from the CD image. It will load the correct driver. After this re-connect the device and the CD image will show up for a few seconds and disappear. After this the storage will show up. That is how it worked on my device.

I have already tried what you said as I posted before. The LG United Mobile driver gets installed but the MTP USB Driver does not get installed due to the device being unplugged according to Windows, even though I have yet to disconnect the phone from the computer. The phone still says "Connected as an installer".
The phone is recognized as an F: Drive by Windows but LGE Mobile but keeps disconnecting and reconnecting every 20 seconds or so.
I am going to have to upload a video to YouTube to make things crystal clear.

Try a different USB port or cable. My P769 would not work on my USB 3 ports, but was happy on the USB 2 port. I had already installed the drivers and LG PC Suite and it picked up each mode just fine.
Plugging the phone into USB 2.0 makes the phone show up in portable devices, but LG Suite fails to identify the phone. I tried using both LGE Android Net MTP USB Device and MTP USB Device but they both fail. I have LG United Drivers and LG Suite installed already.
got thesame problem here mate..i search all over here and google the driver but still cant find any solution..this is so frustrating to fix this issue,,got install and uninstall the pc suite and driver many times but still cant get the solution..so what could be the fix????
no one can suggest..someone told me that maybe its causing the broken data cable but i have 3 cables now..
everytime i intend to install the MTP driver thing my pc always failed to do so,,saying that the filename,directory name or syntax label is incorrect..but i manually direct the search to lg driver folder but same error occurs..or there still other alternative apps that can transfer files without removing my sd to my phone,or atleast transfer files over the wifi..??
Any fix for this one? Already tried uninstalling, installing LG drivers, removed and reinserted SD card and everything. But still to no avail. It installs everything successfully EXCEPT USB MTP device which is the one I needed the most. Any solutions? Thanks!

You must be on 64 bit windows. Not even on 64bit, Still try this...
1) Uninstall LG Drivers, LG PC Suite and anything you see named LG. Restart PC.
2) Install latest LG Driver from this post (step 4)
3) Install Optional MTP Driver from this post (step 4)
4) Open Windows Device Manager (just to watch whats happening.)
5) Disconnect Internet (To avoid stupid online WDM drivers)
6) Connect phone with Usb and let drivers install automatically. Give it some time to install drivers keeping watch on Device Manager window.
7) Keep changing USB connect modes to all modes one-by-one on Phone and let drivers install.
You should see MTP drivers installed now. If this does not help, cant think of anything else. If this works, press THANKS button
EDIT: Connect USB at backside of pc, directly to USB on pc motherboard.

2. Media Player 10/11 preinstalled,
3. your LG Driver,
3. LG Phone,
4. and Media Transfer Protocol Porting Kit (mtppk12.exe)
1. with phone disconnected install Media Transfer Protocol Porting Kit
2. when asked to restart the PC, go ahead and restart
3. open device manager, connect phone to PC
4. install driver and watch LGE Android MTP disappear
5. be sure to toggle between Charge and MTP on the phone to install all drivers
this also works for HTC MTP

[Q] ADB driver/composite device problem

Hi there,
I got a really nasty problem here: when I connect my Sony Xperia T to my home computer, the ADB driver will be installed properly. When I connect the same phone to my work computer, Windows just doesn't want to accept the drivers. The following things are equal:
- USB debugging is always on on the phone
- Both computer are running Windows 7 64bit
- On both computers I am pointing the Windows driver installation at the same folder with drivers downloaded from Sony.
The thing that is different is the device ID that Windows reports in the Details dialogue from Device manager:
On the home PC it is:
USB\VID_0FCE&PID_5182&REV_0228&MI_01
USB\VID_0FCE&PID_5182&MI_01
On the other PC where things go wrong it is:
USB\VID_0FCE&PID_5182&REV_0228
USB\VID_0FCE&PID_5182
So it seems Windows is not recognizing the phone as a composite device (MI is it multiplexing identifier?). I double checked that USB debugging is always on and also rebooted Windows.
What could could be causing this strange problem?
Android version is 4.1.2 (original Sony firmware).
Thanks
Tom
You could search for the adb drivers for your phone on Sony's website, maybe they are available there

This is exactly what I did! Downloaded the adb driver from Sony's website. Installed them on one computer - works. Transferred exactly this driver package to the second computer with a USB Stick.
On the second computer, Windows does not find a matching driver for the same phone in the same driver package.
The reason apparently is that the phone reports a slightly different USB id when connected to the second computer (missing the MI at the end of the ID, see my original post).

Unlocking bootloader frustration

Basically my phone stops being recognized by the computer once I reboot into the bootloader. To be clear, the phone is recognized just fine and shows up when I type 'adb devices' when the phone is operating in the android os. Seeing that all is well there, I proceed to 'adb reboot bootloader' and it appropriately reboots to the white screen with the android on it. But there the problems begin: It reads on the screen:
FASTBOOT&RESCUE MODE
Please Connect Usb Cable to
Your Computer and Open Hisuite
More information:
the huawei website
Then it displays the droid
Then it says:
Phone Locked
FRP Unlock
I tried going ahead and running 'fastboot oem unlock ###...' but it just sits there waiting for a device to be connected. I have tried multiple USB drivers on my 2 windows 10 computers. I have removed all drivers using USBdeview and tried different drivers. Windows will not allow me to point to manualy choose my driver, instead saying, 'The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with windows for x64-based systems.' So I tried it on an old 32-bit windows 7 system. No joy. I've tried multiple USB cords and ports. In windows device manager it has the device labeled as 'Kedacom USB Device' -> 'Android Bootloader Interface'. I can't figure out what's going wrong other than to say it seems that Windows is not using the correct driver once it enters the bootloader. PLEASE HELP!!!
Surely you have a drivers problem.
Are you using Huawei or Google adb drivers?
I couldn't find any Huawei drivers. So I used the drivers from Android developer site and several others I found here on XDA. If you have a link for specific Huawei drivers that would be AWESOME!
Try HiSuite.

Huawei official website
same issue, different flavor....
I'm having this issue as well, on a debian system. I have good ADB connectivity, all ADB commands seem to work fine. With fastboot, I get a device listed form them fastboot devices command. After that all fastboot commands are "waiting for device". If this is a driver issue, any hints on how to install those drivers in Linux/Debian? I tried a number of google searches, and have found all sorts of information, but nothing telling me where to put which files where to get the working drivers. Any hints?
Are you on Windows? Check if the device manager shows the device as Android with an exclamation mark inside a yellow triangle.
The problem could be with Windows 8.1/10.
Try with Windows 7
Here are the official drivers for Windows x64, ripped from Hisuite:
Mediafire | MEGA
Windows 10 is fine, it's what I use and have zero problems. Most of the time is other software that conflicts.
I'm facing the exact same issue (using Windows 10). I did the oem unlock using the code from Huawei. However after connecting the phone via cable to the PC, it does not allow me to browse the storage (internal or SD card) of the phone. All I see is a device named KIW-L24 which appears as an empty folder, and a virtual CD drive HiSuite. I installed HiSuite and the software shows me the photos/apps/etc. however there is no way to move files from the PC to the phone storage. Any pointers to the process to install the right drivers?
can you give me the link for huawei official win X32 drivers pls?!
Install hisuite , it will install all huawei drivers that u needed
