Hi there,
I recently bought a cheap lg G5 from eBay which said it was stuck on a bootloop. The seller said they weren't very tech savvy and I decided to give it a try, seemed fun. I have never done this before, so when searching on Google I stumbled upon threads saying it should be rather easy to fix by using LG Bridge and let it recover/repair the installation. However, after installing LG Bridge and LG Drivers from their website , every time I boot the phone in Download mode and it progresses into a firmware updating screen, my Windows 10 64bit fails to connect the device properly and prompting me with the following message:
USB device not recognized.
The last USB device you connected to this computer malfunctioned, and windows does not recognize it.
And in device manager it shows "Unknown USB Device (Device Descriptor Request Failed).
Is there anything I could try? Is it fixable like I thought?
Bump, anyone? Im stumped but would love tot learn about this

I have never had the experience to get a bootloop but my guess is that you have some driver problems, thats why its not well recognised by your computer.
Try to check if there is a youtube tutorial with some links to the drivers related to the G5.
Sorry if this isnt very helpful, but its the best I can add to this topic.

Or try with another pc running windows 7, maybe your OS and compatibility is the problem!
Definitely a driver issue! I had a similar problem with moto x4! It was not being recognised by my pc! Uninstalling the previous usb driver fixed it for me! Try to remove any remnants of drivers you might have installed previously.
Thank you for the replies. I also thought it would be a driver issue, however I have already tried uninstalling and reinstalling the LG drivers for the LG G5 multiple times and I did not get it to work. Unfortunately, I do not have a Windows 7 computer. Would it be possible to install windows 7 solely for this, without a license key?

If you can find a copy of it some where. You can use it for like 30 days or so before activation.
I do not know any coding, and have never even rooted a device, but i had this problem with stock rom 8.0, tried looking into flashing new stock rom installed all the drivers, still couldnt connect to pc. After 4 days with no phone i thought id throw my other battery in it, it booted up perfectly like it was out of the box, probably because i tried the restore in safe mode... Hope this helps... P.s. id like to learn

I might have missed the perfect advice in searching here and there, but I couldn't find it, so I'm asking here.
I tried applying a nightly build for Cyanogen for Vibrant and now the phone is basically bricked.
It starts up, shows the Vibrant logo, brightens a bit, then shows a screen that in a second or two fills with random color noise, then restarts. This cycle repeats until I pop out the battery.
My model apparently won't respond to vol/power keypress combos to activate recovery or download mode so that was out.
I bought a microUSB jig and was able to get in download mode but ODIN doesn't ever recognize it.
I tried the adbtool to send it into recovery but it doesn't see the phone either.
I tried the AIO Vibrant Toolbox to reinstall drivers/odin/etc and it didn't help.
Finally just watching device manager seems to indicate that plugging it in and out doesn't absolutely nothing. Windows XP never sees a connection. I tried on a Windows 7 machine with similar results.
Any suggestions? Out of warranty so that means no replacement.
Thanks.

Since you flashed cm7 you will need to install the Nexus S drivers. The regular Vibrant drivers will not work so that is likely why ODIN wont recognize the device. If you can get into download mode you shouldn't be hard bricked. Here is a link to download the Nexus S drivers (I believe this is the one I used)
http://dl.dropbox.com/u/8116690/Nexus S drivers.zip you might have to manually install this.

This. If you are able to enter into Download Mode, you aren't bricked (unless you have a really really really bad luck).
This was extracted from the CM7 Q&A Thread on the Q&A section:

Q: Where can I get the Nexus S drivers?
A: Download and install the Android SDK here then download "Google USB Driver package, revision 4"
Once downloaded, right click on "Computer", "Manage", "Device Manager", "Nexus S", "Update Driver Software", and point it to wherever you isntalled the SDK

Djluis, Good write up and assist...........
Thanks - I did try the above but when my phone is connected via USB the computer doesn't react at all. It's like I haven't plugged anything in. My other phone, a Nexus One, is recognized though.
Any ideas on how to force the install of these drivers before I have to pay connexion2005 for his services?
Thanks.

Uninstall Samsung drivers, reboot PC, install drivers from aio box found in sticky thread or from samsung website. It should work. Also try heimdall if odin still doesn't work.
Sent from samsung vibrant
Tried the uninstall - no luck.
One issue... I'm not sure that USB Debugging Mode was selected before this all started. Could that be my problem?
Kermit Woodall
Hi,
try a different usb port and different usb cable
No luck. I suspect that this unit has a slightly bad USB port as well. Fortunately unbricking is affordable so that's what I'll have to do.
Thanks everyone for your advice.

go to best buy, get a blackberry or HTC usb cord. most if the "bad" usb ports are the sh*T%y korean cords ( not knocking the people, just the company )
Thanks - I actually tried several USB cables - including some HTC and a Motorola one. None worked w/the phone - but worked fine with any other phone.

Hi,
Need to know if someone has connected the phone with "Motorolla Device Manager" through USB? If so how?
From past two days I have been trying mine to connect, however, it only connects to the windows and I see the files etc. but not to the MDM.
I tried un-installing, re-installing, re-booting but nothing seems to be working for windows 8.1 64 bit.
I have googled and searched on the Motrolla site with no luck.
I have unrooted Moto-E XT 1022 4.4.2.

The MDM is still not working. When it's installed at the last step the installation says that the MDM icon would appear. It never does. Manually starting the MDM, starts the software updater which also errors out at the end. See attached screenshots.
After some work around on enabling the USB Debugging and then turning on the MTP, I do get a Media device on windows. In the drivers I could see the Motorola ADB Interface and my XT1022 as a portable device. See attached screenshot.
Strangely, when both the MTP and PTP are unslected then with only the USB debugging on, the device is not recognised as the windows doesn't find the drivers. See Attached screenshot.
Probably, the problem is with the MDM and it's drivers which are Motorola specific.
Another question I am wondering about is what functions does MDM provides, apart from software update?
Use this.. Uninstall Motorola device manager, reboot.. Then install it..

Also please search the forum before posting.. I found this on frequently asked questions thread in q&a section.. Hope it helps[emoji106]

Still the MDM is not working.
These seem to be older versions of the driver. The problem seems to be specifically with the MDM and it's specific drivers as I am successfully able to connect to my Moto E for Tethering & use it as mobile hotspot.
Can any one point me to the functionality of MDM?
Same question

Motorola has released Motorola Device Manager V2.5.4. This has solved the driver related issues I've had on Win 8.1.
Uninstall the older version before installing the newer version.
Edit: Download Motorola Device Manager from https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
I installed 2.5.4

Sorry, I am still suffering this problem
Same problem here..
anyone got a solution?
I am using Windows 8.1 64bit. Mdm is working fine for me
Sam problem here with Windows 8.1 64-bit Motorola device manager 2.5.4
On the same computer I was able to run virtual machine with Windows 7 32-bit and it worked correctly. So it is nothing wrong with the hardware on either end. just Windows 8.1 driver issue.
So here's a idiotic move I made while trying to unroot my T Mobile P76920h L9 phone. I tried one thread on here but it wasn't working so great. There was an error I was having so I took that error to Google and found some people who had the same issue. Their solution was something that I believe is what caused my now problem. Their solution was in C:\ProgramData\LGMOBILEAX to delete all that and replace with some exact same files.
Pretty much after that, everytime I plug my cell phone into the my laptop (Win8, Toshiba) my phone isn't recognized in the Device Manager usb ports. I tried downloading drivers and nothing is working. I can't proceed with my original unrooting goal and now I'm at a wall. Please anybody know if there's a solution? I'm thinking just deleting all LG from my laptop and downloading drivers again would be a solution, just have no clue if it is actually.
Thanks
Hello wise XDAers....
Ok so my goal is to get my new vs985 12b to CM12 or something cooler. So first step I need to downgrade the phone in order to root. I've been trying to follow the instructions here http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html?m=1 but I seem to be stuck at step 4 - getting the phone to be recognized by Windows in firmware update mode. I have tried 3 Windows 7 machines and a VM W7 machine. Granted the 3 machines are similar HP laptops. I think they are all 64 bit. I don't have a COM/LPT in the Device Managers, not after showing hidden devices and there does not seem to be a BIOS setting which affects.
In firmware update mode I've got yellow flags on CDC serial, lge android phone and vs985 4g. Are these even the right and complete list of device manager items I am to install? I'm hoping one of these I can edit to get the COM port setup? Some have said to enable debug mode or ethernet USB mode - but these options are only available in normal boot mode in the phone; I did try and turn on debug nonetheless (though it was greyed out, it did seem to check the box??) and I could not find ethernet mode. I do see some posts on the internet that others seem to lack this option, perhaps in 12b it was removed. Further it does seem that many new machines lack a COM/LPT port, so I don't know if there is a way to emulate this or if the drivers for the LG set this up? I am using the LG's dedicated usb cord and have tried multiple usb ports.
I am trying the Windows drivers available on the LG support page for the phone but there also seems to be Verizon LG drivers. Not sure if I am supposed to use one or both or if once installing it one or the other it screws things up and how you are to remove? The VZ drivers seem to be removable under "uninstall programs" but not the LG drivers. I also have been trying to get Windows update to auto install the drivers, but does not seem to work. Here are the two I have been trying:
LGUnitedMobileDriver_S51MAN313AP22_ML_WHQL_Ver_3.13.2.exe
LG_VZW_United_WHQL_v2.14.1.exe
Am I doing this all wrong? Is there an easier way? Help!
Hi, just a quick reply that's not all inclusive as I'm at work and I'm going to hurry. You don't have to bother uninstalling the regular drivers. Installing the Verizon drivers is what you need to do, and it'll be fine if you installed the other drivers first. I'll try to get back about the rest of your post later.

Thanks roirraW "edor" ehT! I've got the LG_VZW_United_WHQL_v2.14.1.exe installed now, so I guess the issue is in firmware update mode I've got yellow flags on CDC serial, lge android phone and vs985 4g. On my virtual machine w7 I do have a lpt/com in device manager, but none of those 3 items are in that parent item. I guess if I figure out how to install them properly, they might "go under" the lpt/com parent entry? I've tried all the USB ports and tried rebooting the phone and computer several times. Tried letting Windows update search for drivers to update (if you rmb/properties on these items with yellow flags it says the driver is not installed despite the installed Verizon drivers). Not sure what else to do.
OK! Think I figured it out! Got the right device installed with the latest Vzw driver from LGs site - seems to be version 20.

Excellent! Glad to hear it. I couldn't resist coming back to try to give you more ideas (I was going to suggest rebooting with the phone unplugged, and then plug it back in). I work with VMs a lot so that aspect interested me.
Cheers!

Thanks mate! I am not out of the woods yet - now having an issue in the flash tool, posted here: http://forum.xda-developers.com/verizon-lg-g3/help/q-t3035198
So after flashing 10/17/15 release of Tesla Arc_Flash I am unable to connect to the phone through adb without deleting the driver and adding it as an adb device. I have installed the LG G3 Verizon drivers but I am still not able to connect. In the device manager it shows that the drivers aren't there but also that they are there as a portable device. hxxp://tinypic.com/r/30ua82f/8
Also the command prompt is below. Brand new adb server started.
hxxp://tinypic.com/r/71myr4/8
Any help would be appreciated. If you need logs or anything else I am happy to provide it. Also since I feel this may get asked... Yes I have USB Debugging turned on. Have tried with Root for adb on and off and nothing seems to work. I can get it to connect through network but I don't want to constantly have to look for the IP address and port. This was also an issue in the previous release of Arc_Flash so please let me know.
Hi! Exactly what drive did you install and where did you get it from? Here is where I get the driver from http://www.lg.com/us/support-mobile/lg-LGVS985. Try rebooting the PC (without the phone connected) after installing the driver. Using the original cable that came with it, connect the phone to a different USB 2.0 port than you had tried previously - it can take up to 10 minutes to finish loading the driver. When it's complete Device Manager should have a listing for the phone in the Modem section, which isn't currently listed in your screenshot. Until you can get that solved you won't be able to reach it with adb.
Have you searched the Tesla ROM thread to see if anyone else has had the issue, in case it's specific to Tesla?

I searched the ROM thread but found nothing matching what I am experiencing but I followed everything even close to it. I installed those drivers just now and restarted both computer and phone. Still comes up as an unknown driver. There is no modem section inside of the computer still. I can manually add the drivers but it still doesn't seem to help.
Also to add. I also have tried to add it as a modem and it gives Windows Error code (10) that it can not start the driver. I forgot to mention. Windows 10.
Well, I've connected to my phone via adb and used the LG flash tools on Windows 10 last week or the week before, although I have my insider updates set to Fast Ring and I kinda regret it because there was a recent huge push of a beta Windows, and they've broken how I had my video associations set up and I can't get my subtitles to work any more either. Sorry for off topic. My point is since Windows 10 is considered a constant "change in progress", and especially for people like me who joined to get "insider" builds, it's hard to tell what makes things not work. My main reason for even being on Windows 10 is to see what they come up with in their insider builds, but I guess when it mucks with my video enjoying ability, I start losing my patience.
I would seriously consider trying a different PC, or if you have the capability of performing a fresh Windows installation, even of Windows 10, that very possibly would fix it. Or if you just recently, within the last 30 days, upgraded from an earlier Windows to Windows 10, and didn't perform a clean installation, you can revert the upgrade through the the Windows settings. No idea if reverting would solve the problem, either, though.
As @bweN diorD pointed out in another similar thread just yesterday or the day before, when someone in your situation ends up trying a different PC, then everything goes smoothly. As far as the cause, there's too many variables.
If you can't use anyone else's PC, there's an outside chance that you could even do it at a library computer, as long as you don't reboot the PC (which I usually recommend after initially installing the driver, but sometimes things work fine without that). Rebooting a library PC usually undoes all changes, putting it back exactly the way it was.
Let us know how you make out.
