[Q] Computer won't recognize download mode, help?

Does anyone know why a win xp computer would recognize the debugging mode, I'm rooted and the one click root worked fine, but not recognize my phone when in download mode? I have the drivers installed and java sdk installed. Every time I go to download mode and plug in I get a pop up (on computer) that my device is malfunctioning and the device manager says unknown device.
I know it's not the cables because I used my brothers laptop to flash eb13 from the froyo install tool before installing syndicate. But three computers including mine have failed with this same message.
I'm confused why this one lowly laptop that is nothing special worked fine and my computer along with the other 2 give me this "usb device malfunction try connecting device again, if fails replace device". Not an exact quote.
It's a long drive to my brothers, and I would like to use odin with out having to wait a couple days til I can drive out their. It's been putting a cramp in my rom flashing mojo. Any help would be greatly appreciated. I have done a bit of searching and haven't found a solution yet, among,

Try downloading the XP drivers from Samsung and installing them fresh. I had a similiar problem. My computer took almost 10 minutes to connect all drivers the first time with new drivers. Then Odin worked fine after that.

[HELP] Epic 4g win7 64 odin [HELP]

So I have done something to my epic, I don't know if it would count as bricked soft bricked or whatever but when I turn it on it bootloops on samsung logo but I can still enter download mode, So I figured I would flash a stock rom with odin and start over.
I went to this thread
http://forum.xda-developers.com/showthread.php?t=1052813
downloaded necessary drivers
installed and tried to connect to odin
I've tried every combination of powering the phone with the computer, then putting in download mode
I've tried powering on with battery booting into download mode opening odin selecting pit and tar and then pluging it in and nothing.
when the pc does recognize the phone it says device not recognized or device malfunctioned.
I saw a post somewhere with someone saying I needed to "advanced install" the drivers. So whatever that means I tried to uninstall the device from device manager while plugged in in download mode and updating the driver to the 64bit samsung usb driver and it says "unknown device already has best driver installed"
the computer I'm using is an HP DM1-4010us not that I think it would matter.
If anyone has anymore suggestions, or can suggest a method or pattern of step by step what I need to do
maybe install the drivers in a different compatibility mode?
what about odin compatibility?
System UAC is turned off and firewall is off too just in case it may be blocking odin from communicating with comm ports so I know that can't be the issue.
Thanks for listening to my overly detailed and confused ramblings and thanks in advance for any advice or help offered.

Try a different USB port and cable the stock cable sucks azz try a blackberry cable.

Have you tried a different usb port?
I have always used the cable that came with my epic, are you using it?
I'd at least open odin, put your phone into download mode and then connect it to the PC and see if with the stock cable it is recognized. That will tell you perhaps the cable you're using isn't connecting right for odin's use.
do you have any other cell phone drivers on your PC? I've seen where they conflict. Remove all cells phone drivers, reboot, install the epic drivers for win7 64bit
EDIT: damn i type slow. someone got itn there already

Heimdall fails to install drivers or detect the device, does this with AND without the samsung 64bit drivers installed.

Try downloading kies air to get drivers.

Make sure you downloaded the drivers named "Samsung_Mobile_Drivers_V1.3.8.." if not then that's the problem, if you need it I can email you the the file. Try all the usb cables in your house and all the computers as well, and take out sd card, I've also had this odin problem and I'm also sure it's your drivers since there are like 10 samsung drivers floating around lol.
Edit: nvm I downloaded the drivers from the thread you linked and they are correct.. try different cables, no battery no sd card, and different computers

fastboot mode

Hi guys,
i wanted flash some new kernel, i have currently Rush kernel. So i opened freshly installed FlashTool (0.90.10.1) with installed drivers from /drivers folder, take out battery and press "menu" and connect cabel....just like million times before. But now the LED just blinked blue and phone bootloops until i pull the cable out. And just the same happens when i want to go into flashmode (green LED) it just blinks and get bootloop. Can someone give me some advise? I am using original SE cable that comes with it.
edit: i am not using USB controller, i am using USB that comes right from motherboard
edit 2: even if i try "reboot into fastboot mode (via ADB)" in flashtool, it reboots into CWM...

just the same...
hmmm, but now the weird part, when i put the cable, just the cable without phone connected to it, windows told me, that "some of devices was not recognized" and drivers was not installed for unknown device. What the hell does this mean? drivers for cable?! btw: the cable is barely used i flashed with it two Arc S just week ago.

Sounds like a PC issue to me.

nope it was that cable...i don´t get it, but with another one, it just works. I am using sometimes that "non-working" cable for file transfer or charge battery and it works normally. Strange...

LG G3 not being recognised, USB not transferring files

I'm hoping someone can help. I have an LG G3 D855 phone and is factory unlocked and running Lollipop 5.0. When I first got the phone (second hand), I was able to connect the phone via USB to my PC and was able to transfer files back and fore no problem. Until about 3 weeks ago, I am now unable to do this. The PC won't recognise the phone at all, all the USB connection does is charge the phone and I can see no option to get the phone to change to file transfer mode.
I had a look at Storage in the settings menu and I don't have the three dots that some people have spoke about. I have factory reset the phone and this hasn't fixed it.
I have tried using a different USB cable, this was the same. The drivers are installed (phone was recognized before). I have also tried the LG Suite, again same result. I also had a look in Device Manager for ACER something or other and this wasn't there.
I am currently having to use Bluetooth to transfer files back and fore to my PC and this is a bit slow. I'm assuming that an update LG have done has somehow broke the USB settings. I am also unable to root the phone (tried this before the USB stopped working and nothing worked) and possibly go back to KitKat 4.4.2 to even try that.
My phone has software version V20u-EUR-XX, Kernel Version 3.4.0 and build number LRX21R.A1439960697. There is no update available for my phone in the Software Update center.
After quite a bit of searching, it seems that this is a common issue but I have not found a solution to this. Can anyone help? Is there any firmware or software that I can try?
Thanks.

Assuming the OS is Win8/8.1 or Win10, have you already tried this?...

Thanks for the reply. I am using Windows 7 Home Edition 64 Bit and had had a look for the ACER Composite ADB Interface in Device Manager and it wasn't there. Post #18 in the thread you linked to, I have no idea what kdz file I would need. Does this method need the USB to working?
Thanks for the reply and help.

I have D85520T_00.kdz and D85520U_00.kdz files. Can someone tell me if these are OK for my phone (and latest) and what the differences between the two are (apart from the file names?) Thanks again.

I couldn't tell you what the differences are between software revisions, only that 20u is newer. And I believe 20w is the latest available. I would probably try reinstalling the latest drivers from LG...

... then again check to see if your PC recognizes the phone. If the "Charge phone--> Tap for more USB options" notification doesn't appear after installing the latest driverset, I'm not sure what else you could try. The LG Flash Tool needs to be able to communicate w/ the device when it's in Download Mode. You might be able to find something in the [Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ & TOT Method thread related to the same problem you're having.

Just a quick update, can't even get the phone into download mode. I press volume up, insert the USB cable in to the PC and all I get is the battery charging icon. I'll have a further look this weekend - not good so far!
Thanks again for the replies and help.
Firmware W seems to be flashable only via TWRP or ClockWorkMod just now?

I have been able to get the phone into Download Mode a few times (not all of the time) and when I run LG Flash Tool, it just tells me that the phone isn't connected. I'm going to assume that the USB port is in someway defective. Can't think of anything else.

Have you tried w/ a different PC and/or OS? Have you tried connecting the phone via different USB ports (USB 2.0 compared to USB 3.0 or vice-versa)? And I assume you've already installed the latest driverset from LG?...
http://www.lg.com/us/support/software-firmware

Yes, I got into Download Mode once or twice on the laptop. I'm using LGMobileDriver_WHQL_Ver_4.0.3. I have tried USB 2 ports on both my Laptop & PC. I've tried driver 3.81 as well.

OK, got a new USB Charger port fitted just in case it was the port that was wrong and it's still exactly the same! I did a factory reset and have setup the phone for now. During the factory reset, it does pop up with Updating Android and has 169 updates. If anyone here has the LG G3 and has it working file transfer wise, can you tell me what version of the LG USB drivers you are using? Is it possible an LG update has caused this?
Thanks.

It's fixed!!! I think there was an update yesterday for Android Devices or Services, can't remember which was made available yesterday, installed that, reconnected the phone to the computer just a few minutes ago and it has finally been recognised! I can finally transfer files between the phone and the PC.
It was an LG update that has fixed this.
At last.
I'd like to say thank you for all the replies and help.

My 5X is not showing up in windows at all (drivers are installed correctly)

Hello,
big problem here.
My 5X just stopped showing up on my PC. It used to work fine before, but then stopped a few days ago.
I thought it might be related to the Encryption, so I just wiped everything (internal storage). But still the same problem and now I dont even have an OS installed. It's not even recognized in fastboot mode.
I ordered an USB OTG Adapter now. Hopefully I can push files with an USB stick to the phone then.
Any suggestions how I can make my Windows 10 recognizing the phone again? I also tried different Windows 10 PCs. Its not even showing up in device manager, no sound at all when I plug it in, its just charging...

I have a similar problem. My phone shows up in device manager, but I cant access the phone at all and in device manager it says no drivers are installed. Can't seem to install them again. Are you in the beta program and running 7.1.2?

Nope, I was running Resurrection Remix N 7.1.1

So I managed to push a ROM to my phone via USB OTG.
I tried 2 different ROMs, all stuck on bootloop. Any idea?
It still doesnt get recognized from my pc.
