Unknown Device connection to pc - Sprint LG G2

All I want to do is flash back to stock, I feel like I am gonna lose my my mind or go buy a new phone. I have mostly spent a solid 10 hours of time trying to get it to work.
I have been endlessly looking, searching, trying all these different methods to get my ls980 to connect to my pc. So basically everytime I have hooked it up it comes up as unreconized or unknown device doesn't connect.
List of things: Latest LG mobile drivers I have installed them through there exe and tried to install them manually when the ! comes up on the device. I have tried my laptop and my desktop every usb in all of them. I have tried the stock cable, and about 8 other different cables. I have tried it in debugging mode with mtp and without debugging. I tried the support tool as well. Tried composite usb setting.
I guess I am at a loss at this point to what even to try besides sending it to be repaired. Which I don't feel like it's a phone problem and I am just missing something I can't find, I say this because the phone charges perfectly fine and no damage to the usb port at all. If anyone has good information or just a direction I can go will be greatly appericated.

Is your device functioning normally, besides from this? Also, did you use the T-mobile drivers?

It works just fine, only notable thing that I never figured out was why OTA updates don't ever take, it's still on ZVC. I tried the T-mobile d802 drivers as it was suggested by another post I saw on here.

And you've removed all drivers to android and lg for it.

Correct, I uninstalled them, tried new ones a couple different ways from other posts, and removed them and tried again. Right now I just have them all uninstalled. Trying to figure out if it's something that's stopping it. In error I did forget that a couple times it reconized it but would :fail to start code 10.

Which version of windows are you running? On both desktop and laptop???

OK, that shouldn't be the problem. Zvc yet updates do not take.
Is it rooted?
And it is running on sprint network?

Long story short, it's on ZVC, even with other updates that came up it would never update past it. I took it into sprint several times they didn't know why, I did root it as one guy said that was an option, I used stump root, but then I unrooted as I felt I was getting into something too complicated. It is on the sprint network, about 90% of the time and all the times I tried to update previous to the root/unroot. But I am not trying to update it since the root, mostly trying to restore to stock and start overish.

I'm thinking maybe a virtual machine with Linux might find it. If it can then there is something. And maybe we can redo the partitions and such.

I was unable to find anyone outside local computer store that I know. Kind of problem finding that in rural midwest. I also tried installing drivers in vista compatability as that was suggested no luck..

As for driver removal, one thing I remember with the nexus devices. There is wugfresh nrt, nexus root toolkit. Let me see which application or program they loaded for removal before reinstall of drivers. I know they have 2 places you check into.
Dang, I'll have to try to load them via a windows emulator. I'm running Linux right now.

Let me know.. I am kinda at the point where I might try to find someone to flash it back to stock, and just activated my old phone til it gets back.. like I am past the point of frustration and no legit just don't get why, since all my other devices have zero issues connecting.

please help with root issue (searched for 2 days & tried everything)

yes i have searched endlessly.
no i am not in anyway new to rooting (not claiming to be on the level of probably most here)
i have tried everything to get my replacement DInc to root. one confusing issue is that the error i get seems to bounce around all over the place. from back CID missing, to failed to gain root, to failed to flash recovery and is your firmware too new. i have tried:
* multiple versions of unrevoked.
* with and without sd card
* on charge only and on disk drive
* with and without firewalls enabled.
* did factory resets
* flashed a new RUU
i am almost sure i am forgetting something here but cant think offhand as i am about to go crazy with this thing. please if you have any suggestions then i will try anything. i know it may sound childish but if i cant root this thing after being used to it then i almost assume go back to my old razor.
thanks in advance
Sure you have the correct drivers (for windows machines)? Sometimes people have had to use different computers, couldn't hurt if you have access to another machine.

well yes i am sure that i have the correct drivers cause i broke out the other device that i havent sent back yet and it rooted using the same items that i have been attempting with this one for 2 days now. i can attempt the root on a different machine shortly when my parents are up, will post results.
any one else have any thoughts care to share?

Try setting up the drivers from scratch for you new device. The same drivers worked when I rooted my buddies phone, but I had to re-download them from scratch to get it to work.

already tried this. actually i just installed windows 7 ultimate on my laptop just a few days ago so it was completely clean. did everything from square one with no changes in issues. i called verizon today and told them that the replacement device i received was doing alot a odd things (no mention of real issue obviously) so without hesitation he said he would send me another out. so hopefully there is just something about this particular device that is abnormal. i would still like to keep hearing opinions and trying solutions tho. who knows that something in the refurbish methods arent causing this currently. thanks to all.
anymore guesses.
I had problems using Unrevoked on windows. I put it on my Mac, and it worked the first time, no drivers or anything needed. Probably not the most helpful advice, but if you have access to a Mac, might as well give it a try.
Uninstall dropbox and PDA net if present. SD is fat32? Using stock USB for device? Launching unrevoked as admin? Right click on the exploit before running, see if properties show it from unknown computer, and unblock it if needed. Same story with the drivers, check and unblock from properties, then reinstall as admin.
Tried a different USB port on the PC?

wanted to post back the outcome which hopefully at some point will help someone. i made sure every possible combination of drivers, programs, menu options enabled/disabled appropriately. nothing fixed this. verizon sent me a new device out (obviously they werent told my reasoning), powered it up, plugged it into the same computer and 2 minutes later was rooted with not the first issue. thus i have concluded that there had to be something in the programming that would not accept root. unsure how considering i even ran the RUU multiple times. thankfully they sent me a replacement for my replacement cause dealing with a stock phone after being rooted just would not work out.
thanks all
Yea if that phone was having that much trouble getting root then it probably could have bricked in the long run. Good thing you did get a replacement and were able to root in the end.

[Q] Semi(Soft)-Bricked Unflashable Epic - What to do now?

*First of all, let me say that this is a repost from here (http://forum.xda-developers.com/showthread.php?t=1153310&page=27), and I apologize for that fact. I have been severely neglecting food and sleep trying to fix my phone, and I really, really didn't feel like typing the whole damned story up again. Any assistance or insight would be deeply appreciated...
-------------------------------------------------------------------------------
Well, I did it this time I think. I've hacked, modded, wiped, and flashed my phone since I got it last year, and although I've gotten to places where I thought I had totally fuxored things up beyond recovery, every single time in the past I've been able to bring it back from the brink of oblivion. I am exceedingly resourceful and tenacious, which can be both a good and bad thing. Good thing when I am able to fix things that seem unfixable. Bad when I forget about things like eating or sleeping.
Here's the present situation: 4 days ago I was trying to flash a new modem (FB15)(something I know well how to do as I've done it many, many times before) through Odin, when it stalled out near the beginning of the process. This is not unusual with Odin, so I've gotten into the habit of closing it, pulling the battery, and starting again. This time, however, no matter what I've tried, I cannot get Odin to successfully flash. It fails every single time. Either that or it stalls yet again.
At the moment I can only get into 2 modes on my phone: download mode (which can't actually download anything apparently) and the very unpleasant computer--!--phone screen when I try to boot it up or go into recovery. This is the longest my phone has been unusable. I've been intensely focused on fixing it since it was semi-bricked. The ridiculously frustrating and annoying thing is that the computer I'm using (and I've used multiple to try to fix this across Windows, Linux, and Mac) usually says "USB device not recognized" when I plug my phone in while in download mode, no matter the state of the drivers, and when it does recognize it and it is visible in Odin, it means nothing because Odin fails no matter what file I'm trying to flash. When the computer and Odin DO recognize the phone, and when Odin doesn't hang, very occasionally it will give me some odd error message like "PIT mapping not found" or "cannot open COM port". I've tried so many of the things I've tried in the past that have worked: changing USB ports, rebooting the computer between attempts, uninstalling and reinstalling drivers, going into download mode with the SD-card and battery out and in, loading Odin after or before putting the phone into download mode, trying on different computers with different versions of Windows (I even tried one Mac with iOS 10.4 and a Linux notebook with Ubuntu), trying different USB cables, flashing with the battery and SD card out, trying to flash different files (besides the original modem.bin which stalled), running Odin as administrator, yadda, yadda, yadda...on and on, for days. I even just went out and bought a high-performance, super-short USB cable (6-inches) and a USB 3.0 PCI card so I'd have dedicated USB. Nada.
Basically my phone seems to have a broken download mode with potentially wonky USB (Samsung USB has never been good). I've been seeing if I can get Heimdall to work, though there is a bit of a learning curve with that program, no matter how easy people say it is. I've never even tried flashing it with it yet since I haven't gotten together all of the apparently necessary files. I also just found One-Click Unbrick, and while I was excited originally, it seems that the same outcome is the result. No matter what I do to get everything just right to be able to succeed, it fails. Java is installed, Heimdall is apparently installed, and the One-Click Unbrick drivers have been installed every time I've tried to run it. Nada again.
If my phone is able to get into download mode, yet that seems to be borked, what is my recourse? I'm at the end of my rope...*sinks into a depressed lump on the floor*.
ANY assistance would be immensely appreciated. Thank you all in advance. I'm not incredibly hopeful at this point, but I am (fortunately or unfortunately) still tenacious as hell. :-/

I thank you much for your suggestion. I've tried flashing the EC05 modem tar and both the tar.md5 and the straight tar file of the stock EL ROM, though surprisingly I haven't tried the straight EL30 modem tar yet. I'll try when I get home. The main problem is not getting Odin to COM, but getting it to flash anything. It either stalls, fails, or doesn't see the phone...download mode seems to be basically useless.

It is possible you have some crap in your phone's port. Or even the new cable is flaky. Get a bright light and magnifying glass and look in your phone's port. Also try fresh downloads of the files.

I'l check the USB/charging port when I get home from work. Most of the files I've used, including the various versions of Odin, came from my synched Dropbox folder. I'm wondering now if Dropbox synches files accurately. I'll try redownloading every file I use to flash to see if it has a beneficial effect. Thanks for the suggestion.
hope this helps

Let me find you some reliable files
Odin 1.85
Stock El30
Windows 32 bit and 64bit drivers
This should be enough to get you on your way. Oh and if you can at all possible reinstall windows prior to loading these drivers. i know someone who had to do it before their computer would recognize their phone. I've been in this kind of situation i had someone root my phone and is computer was fubar'd and it took him 3 days to unbrick my phone. This is what helped him he kept recieving unknown device. This is what helped is what helped him id advice the same. Once you have windows reinstalled download the three things and install the drivers and give it a shot.

Thank you so much for the time. I'll see about reinstalling Windows, though since it's not my computer I'm not too sure how that will go...hehe. I may be able to restore from the backup partition if he doesn't have a CD.
well you can do it over a virtual machine but unsure how to do this and if this will work entirely it might it might not im not too fluent with virtual machines.. but it simulates a working computer so id imagine you can install drivers and see if it will then recognize your phone.

So interesting that you mention running a virtual machine, as since I can't reinstall Windows Vista on this system, I was considering partitioning the hard drive and installing a version of Linux, then running WINE under that.

I FIXED IT! My phone which has been dead for 5 days lives again! Resurrected!
I thank you all for your time and assistance. It was very deeply appreciated.
I fixed it by circumventing Winblows entirely. I created a second partition on my friend's hard drive, installed Ubuntu Linux 11.10, then went through the pretty simple process of setting up Android SDK/ADB and Heimdall, and all of the dependencies that they required. The ridiculous thing is that I fixed it without even trying. I was simply seeing if Heimdall could detect my phone (which I had connected and in DL mode), which I noticed that it did. I had no idea what Download PIT did, so I pressed it, and lo and behold, it did something amazing, and rebooted my phone. I am elated, exhausted, triumphant!
WHOOT!!!
I kNEW I would figure it out. I always do...lol.
In messing up my phone so many times, I have gotten VERY good at fixing whatever nonsense happens to arise.
Thanks again all.

EDIT: I meant PRINT PIT, not Download PIT. ;-)
YAY!

My housemate is running 10.04, so I'm familiar with how it looks. If it makes ya feel any better 11.10 doesn't like my new usb wireless network adapter (Netgear N900 Dual Band), which is MUCH better than the one to which I had to revert to get internet access, though I'm hoping that I can get it working somehow soon.

[Q] USB No longer recognised

Hey guys,
Just last week my Nexus stopped connecting to the PC. First it wouldn't even charge or show the phone in explorer.
I tried bending the connector back up and it started charging again. But it still won't connect in explorer.
Drivers shouldn't have changed but I've tried reinstalling and still nothing. Tried different cables, nothing. Tried different ports, nothing.
EDIT: I was trying to avoid it but I've tried a factory reset and reflash of PA2.99... still nothing.
So I'm a bit stuck right now. Anyone have suggestions?
Have tried searching and the like.
On a different note, possibly related. I bought a Nexus 7 today and tried to unlock and root. Fastboot drivers aren't working. Tried several different packages and methods. No dice. Followed instructions etc.
Thanks
Jenkss

linux/windows/mac?
can you see your device in 'fastboot devices'?
can you see your device in 'adb devices', while running android or a custom recovery?
check if there's an updated version of fastboot/adb (not sure what OS you're using)
There seems to be quite a large percentage of these phones where the USB port breaks down. Mine was one of them. I had charging issues and my PC didn't recognize my phone. I still had a guarantee and I had it fixed.

64bit windows 7.
Tried with the latest adb/fastboot drivers.
Not recognized in either. Doesnt show up in any device manager.
The only way i know the phone has some form of connection is that the charging icon comes on.
Starting to think its the port that's broken some how. Bought the phone online back just after release so I doubt I'd be able to get a replacement.
Using airdroid at the moment to backup and transfer files around but thinking I might need to think about a new phone soon.

I'm sorry to hear that, but IMO, yeah, i think you should start looking for a new phone. Don't keep valuable data on this one.
Same issue here. I just UPSed mine to Samsung under warranty. They better fix it, since it's their hardware issue. The phone support kept telling me they were going to reflash it. Good luck doing that without access to USB.

[Q] Epic 4G (D700), ODIN and "Unknown Device"

Okay i have seen similar posts around, and I apologize if this bothers anyone but when I post a thread asking for help, its because I've tried most solutions and have gotten nowhere. I recently bought one.of.these devices and I have to say for an old 1GHz device, its pretty darn smooth! (Got it for my girl who broke her phone. Cost $20 MINT screen, and some scuffs.on the trim believe it or not, fully functional, clean ESN)
I love for all devices in the house to be rooted and off that dreaded Gingerbread android. I have been stuck since i got it trying to use ODIN to flash CWM, and root it to flash a JB based rom. Problem is i installed the drivers, got the ODIN version required, have the CWM tar file, etc, the phone gets detected while on in ADB, normal file transfer way and so on. BUT Download Mode? Nope, i get the dreaded "Unknown Device" issue.
Now as I always read before annoying others, I read that switching the USB cable helps. I've tried 8 USB cables, and no go. 2 Samsungs (i read those are #1 NO GOs), 3 LG cables (device doesnt appear at all), and 3 non brand. No good.
I know Mobile Odin wont work, I rooted it using Framaroot.apk for now, but I need CWM for the rom flashing part.
So now that its 2013, is there really no other way other than ODIN? I tried using ROM Manager, it flashes but doesnt do a thing except boot into stock recovery (miracle no bricks or bootlooping). If I had Linux on my PC, will it get detected or its just the darn cable?
OR is there a specific USB cable brand I should go for that is guaranteed to work? I dont mind buying it just have been waiting to make sure.
Any help or advice is greatly appreciated.

Thank GOSH I read your response in time! I am currently at BestBuy and was going to buy a totally different brand USB. Hopefully they have them here.

I use this cable and have had zero issues. http://www.monoprice.com/products/p...=10303&cs_id=1030307&p_id=5458&seq=1&format=2
Well there's good news and bad.
Got an official BlackBerry USB cable.
Bad is the device is STILL not recognized.
The drivers have been properly installed, there is no updating the drivers manually, effing Windows won't let me. What the hell can I do now?
If only Mobile Odin worked, or there were other methods, I wouldn't be going thru this mess...
Like where did I go wrong?
I would swap out Windows to Linux, but I don't see how that will get the device detected.
Matter of fact I was trying to install a Linux based OS from my flash drivd, and it corrupted it. Theres 8gb Ill never see again...
Any other ideas? Will Linux pick up the device?
EDIT: This USB unlike the others BRIEFLY detects it as a USB Device, then goes back to unknown when I uninstall it thru Device Manager

Are you plugging into a port directly on the motherboard? (IE: A port on the back of the machine.) Using an emulated port or hub can cause this at times.
FYI, there are 2 drivers. One is for when the phone is fully booted in Android. The other is the driver when in download mode. Have you tried using another machine?

I think your issue is driver related. I had similiar issues and updated the wiki with the drivers that ended up working for me.

Need root help Odin

Hi, just got my note 4 3 days ago and I'm not new to rooting, however I can not get Odin to recognize, I've tried several Odin versions, 3 computers and 4 cables. I also just finished the last update to PL1 today. What gives, I need trwp to root, not unless there's an adb method.

Install samsung usb drivers.
If you already have installed then uninstall them and install new again then reboot pc.
See if it fix the issue

Cheap hackers number one attack is to uninstall drivers. Once you get rooted I suggest you chown your USB settings to no where. I have to reinstall by samsung drivers before I use Odin every time. There's some great apps like pdanet that will fix your windows drivers but in some cases to well. You basically got a debugging bridge for the world. As far as the drivers in your note the scam is to get you to pay for remote help. I chowned the drivers in it and it's good but I can't get them to let up on my son's S4. Here's the trick - it they don't stay inactive in recovery or dl mode. When you boot into dl they default disable (this may even be Samsung). Pull the battery and wait for about 30 seconds - replace the battery and boot straight to dl. This works for me every time.

Sorry if this is redundant, I can't see that my first reply posted. To get your usb too work in DL mode you have to give it a cooling period from the time you shut it of. The more I think off it it is a samsung thing on new firmware. All though when it happens too me I always get a link from people wanting money to fix it. Pull the battery, wait 30 seconds then boot straight to dl = volume down + home + power. The USB resets after the cool down.

Are you using stock usb cord? I've heard of people having problems with cheap cords.
finally, got it just now, I have never went through this before, I had to remove driver and disable driver about 8 times, and Odin finally did it's thing for me. Now to get rid of those ads!, thanks

It has been getting way bad for my Note 4 S4 and puter. My S4 got so it wouldn't even charge after cold boot. If I didn't have extra batteries and a wall charger I probably would have never figured it out. My pc updated to a invalid copy of sevice pack one and when I plugged my note in to it a note popped up saying this device can not communicate with the device it is connected to. It said that you have to make windows like Mac for it to work right and a bunch of other absuuird stuff. It gave me a link to androidfilesystems.com and said I'll find it there. I downloaded a package called android drivers to check it out. This app says you have to fet your ADB drivers for windows from your android. I was lauging my ass the whole time but I had to check it out. This app opens and it prtends to be pulling stuff from your device. Once out it tries to install and then says it failed becuase my device has been tampered with but they can fix it for me remotely for $200. It seems to have come with stalk firmware from SamM##### They haven't been watching me as closely as I thought. Because the would have noticed the APK decompiler the PDAnet (which has a straight awesome ADB for windows driver. The fast ADB, the android SDK and all of the other things that show that not only do I know windows drivers don't come from android, I will also be taking their app apart to figure out if they are infecting me worse. I pulled it a part and it does have a pretty good driver package for windows and the only malice had to come pre installation and the lie about what they are doing. I still have the apk. it gves me a good laugh when I'm down.
If you had this issue it will persist. Your going to have to fix your driver issues every time you adjust your firmware, unless your straight change all of it. The first step is to not install busy box. A couple of apps will refuse to try but for the most part will run better. It makes way to many sym links to ever break them all. Another is in recovery use the terminal to go to /sbin/recovery chmod the dev files and then chown the usb file -Rwith -L. They are all ready set. There is no reason for it to be sym linked other than for malicious outsiders to turn it off. When you go to sbin you are going to notice TW home has been given down load capabilities and crypto files. Neither of those serve a purpose for the user. I don't know how to break the download on the tw other than to freeze and/or uninstall it and use a differnt driver. You can lose the crypto files with chmod 0755 and cmd wipe_data_crypto. Good luck.
