I have a Verizon LG G2 VS980. The phone was rooted and running stock firmware.
I hit the "Update software" by mistake on a business trip and when the screen went black, I powered off the device in hopes of preventing the update (which I see now was a HUGE mistake.) Now, the phone only boots into fastboot mode. When I try to hold the vol + and power, it takes me straight into fastboot as well as the vol - and power.
I have tried to do the factory reset by holding vol - and power and then pressing it again when the LG splash screen shows. When I select to hard reset the phone, it goes into fastboot mode.
Now, when I plug the device into the computer, the computer will not recognize it. I am using the manufacturer's data cable, I have tried multiple USB ports, I have uninstalled and reinstalled the drivers countless times. Neither fastboot or ADB in command prompt recognize the device. However, the device does show that there is an android device plugged into the computer.
I have spent hours looking through every thread that addresses issues similar to this but I have not found a solution yet. What can I do from here?
First of all this belongs in Q&A not development.
Are you doing the hard key combo correctly? Power the phone down, when when it reboots is vibrates. When it vibrates you hold power and volume down. At the splash screen, you release it then hold them again.
Did you try this thread?

When you held power up and volume on reboot, did you have it connected to the PC to see if you had download mode?

-check your device manager and see if your computer recognizes it.
-Try another computer.
-Another USB cable
Your computer should recognize it since you had it recognize it before.
Yes, I have tried multiple usb cables and have tried to get into download mode both plugged into the pc and unplugged.
Am I correct in assuming that step one needs to be to find out how to get the computer to recognize the device?

Phone is ATT captivate SGH-I897 1008
Had my phone for 4 months or so, most of the time with cognition 2.x on it. Tried to update to 3.02 yesterday, and it had an error in the middle, left me at a recovery screen of sorts, and I chose to reboot from the possible selections. It got stuck on the ATT worldcom splash screen.
I tried several things. First, I tried to boot into recovery mode (vol up+power, then release) stays on splash screen. However, in this mode, if I connect my phone via USB, an adb devices command shows as connected. From there I tried both an adb reboot recovery, and adb reboot download command. The adb reboot recovery reboots into the worldcom splash screen just like the key combo does. I can't recall what the download option did, though I think it worked.
Secondly, I realized I could reliably get the phone into download mode, so I decided I would try the download mode, and restore to stock. I found an ODIN on the seminal ODIN thread, downloaded it, and started it up. Put the phone into download mode (hold vol + and vol -, plug in the usb) and that worked fine, however, ODIN doesn't see my phone. I left the phone in this mode for a couple hours just to make sure, and tried disconnecting, and reconnecting, and initialized the procedure from the beginning several times -- no go.
So, I am stuck, and coming to the experts. Hopefully, someone has some good suggestions. I was unable to find someone in a similar predicament, so maybe I am SOL.
Thanks in advance for any help.
UPDATE:
I rebooted my laptop (windows XP) and when I plugged in my phone, it saw "new" hardware and the name of the hardware it sees is "gadget serial." This might explain, if it is not initializing the right drivers why ODIN can't see the phone. The only problem is I don't have any clue how to redirect it to see the right hardware now.
Success Update
After reading the seminal ODIN thread a bit more careful, I came across someone who had similar issues with the gadget serial device. Apparently the drivers I got (I think from the Samsung site) are not good enough to cover that aspect of use. I installed with the drivers from links on the ODIN post and my phone was recognized! As I type, I am installing back to stock.
Thanks everyone for their efforts, and I hope my experience could be useful.
Desk top or laptop, have you tried all the ports
I would test to see if adb recognizes your device first during normal operations. I'd that doesn't work, your usb port may not have enough power or you have a bad usb cable. I think adb can also restart right into download mode but check around first.

I tried two differing cables, both of good quality. One was the cable that came with the phone, the other was a mini-usb cable with a micro adapter. Neither worked. I can't do normal operations right now (that I know of), seeing how the phone is in a bad state.

Use rear usb ports on desktop. Make sure you are using original oem cord

Sorry, didn't read your first post close enough. I'm not sure what you can do, someone suggested the battery pull method in another thread, but that was just to get their phone in Download mode. It had nothing to do with ODIN after it was in download mode. Hopefully someone will have a suggestion for you. Good luck.
I'm having a similar issue except that odin sees the phone when booted into the rom, which I find odd.
Would you be so kind as to link the drivers?
Hi there, I'm new here but I have been following this forum for a long time.
Here's my problem:
I own a LGP990 with DJANGO rom. apart from the random stuck in the DJANGO loading screen which required me to reinstall it, it was all working fine.
Until yesterday, when I plugged it to recharge. The battery charged for a while and then got stuck for hours when almost done.
I unplugged it and try to turn it on but since that moment it always gets stuck at LG logo screen and when plugged it doesn't display any battery charging. I then tried to start recovery to reinstall from zip as I did every time it got stuck in the django loading screen, but recovery does not start.
No problem, I thought, lets smartflash/nvflash a stock rom and i'm good to go. Wrong, the phone won't even get recognized by windows, though I installed the driver several times (disabling driver signature as well) and running it as admin; i tried different driver versions, different usb cables... It does not even play that background sound when plugging usb devices...
I'm using windows 7 32bit.
That's it, I have ran out of ideas... anyone got one? (besides sending it to assistance, since warranty is voided)
little edit: whenever i plug the battery the phone start by itself!

I meant to enter recovery. If your phone turns on when you put in the battery, the power button is stuck in a connected position so to enter recovery remove the battery, press the vol- and then insert the battery. If you get your phone to enter recovery and reflash the rom I will tell you what to try to fix the issue.
1.)remove battery
2.)press volume - and volume +
3.)connect phone to pc via usb
4.)download apx driver
5.)(go to device manager install manually apx driver, select the folder where you downloaded and extracted apx ini driver file
6.)flash using nvflash
7.)enjoy.

in AIO you have an option to smartflash roms not nvflash. You need to unpack a KDZ rom and install the ROM via smartflash
all the instructions are in the op of the AIO toolkit
the problem still remains, no phone detected and no com port appears in smartflash...

mmmmhhhhh..... change usb port, change cable, reinstall the drivers. other than that I am at loss
AIO tool has an option to install Nvflash driver. Its the last option in a different color.
Or you could try to reinstall LG driver. I just downloaded the latest driver from lg support tool today. It works fine.
And be noted that you have to hold down both volume up and down while plugging the USB cable to enter nvflash mode. Holding vol down while plugging the cable in will enter boot loader mode which is not the same thing. Remember to remove the battery first of all.

hey...ur problem solved??
The info:
Windows 7 64bit
LG P990 stuck at a double LG boot screen. The phone enters download mode (pressing Vol down when plugging USB). Windows finds nothing when pressing Vol Up + Vol Down when connecting to USB.
Tried to NV flash but nothing happens which makes sense since windows don't find anything when double pressing the buttons and connecting it. Am I doing something wrong?
Hello,
Have you ever heard about this useful tool? http://forum.xda-developers.com/showthread.php?t=2020737
Repair your device with it. Also you should have installed all of the USB and APX drivers.
Yes I saw that and downloaded it. But my problem is that the PC doesn;t even find the phone connected. I have installed the drivers. And the phone does find the PC because if I only press down button it goes to download mode.

Use option "Repartition your device....". Follow the instructions.
/*Have you already tried to remove battery before plugging it in to the PC? And while you are plugging it in, you should hold VolDown and VolUp. Screen stays black but PC starts recognizing your device. At least, it works for me.*/
That's my problem...When pressing the buttons and connecting the phone(without battery) the PC (tried 2 systems) finds nothing at all.
Hi all,
I rooted my phone and unclocked bootloader.
My rom is a stock rom.
I managed to install CWM recovery using lg-optimus-4xhd-recovery-v1.0.apk but something happened.
I rebooted my phone in recovery mode and it is always locked to LG logo.
Pressing Volume up and power I can see normal android system recovery, wiping cache and factory reset don't work.
I haven't usb debugging enable so my computer can't see the phone connected with usb cable, and it's impossible for me flashing the phone with kdz rom methods.
What can I do?
Thx in advance for your answers
No one can help me?
Flashing with kdz results in "phone was not found", is there a way to resolve? I've tried with ubuntu, OS (adb) only see my phone if usb debugging is enabled and it isn't, and with a laptop running win8, installing LG drivers and so on, nothing works.
This is salvagable
If you can get the stock recovery mode, all is not lost, all of the important bits are still functioning.
Power down. Hold VolDn and insert the USB cable. If you get the Software Update screen with a green icon you CAN recover the phone. It may require a battle with Windows to get it to play nice, Windows and USB is always a hit or miss affair; but the phone is ok if that screen appears. Do not use the VolUP + Power LG Recovery mode, there isn't a known tool for that in the wild.
I don't normally run Windows and the couple of times I have booted it to do this it required some hassle and usually skipping the nice way since I had never installed the bundled LG Desktop stuff before things went wrong. So just do what I did, pick the Emergency mode that requires inputting the IMEI instead of letting it detect your phone and then let it fix things for you.

Many thanks for your answer, I resolved the problem late at night, yes, after a hard battle with windows.
I installed windows 7 32 bit, I tried a lot of Lg drivers, 3.8.1 maybe the best, after inserting the USB cable with SW Update screen some LG peripherals were recognized but the result in KDZ_FW_UPD was always "phone was not found", then I tried connecting USB cable with the Phone in Android recovery mode ( power & Vol up), and OS added a couple more peripherals, and attempting again with SW Upgrade mode worked.
My 1020 got bricked while flashing through WPInternals.
In the middle of the flashing the USB got disconnected and after that I have blank screen. The power button pressing does make phone vibrate. Also soft reset combination makes vibration. However I am not getting anything on my laptop on USB connection. No connection notification. Nothing on device manager. I tried combinations to get it detected but nothing works.
So the question is, Is there any way I can blindly send force flashing to one of the USB port and make it happen ?
JTAG is the only option ?
same me hichic
Flash Mode
Hello,
try this: power off/reset and power on holding vol-up key. You should get a flash-and-cogwheel sign on your display. If so, you cna reflash your (valid) .ffu file using PhoneImageDesigner/Lumia Flash Tools (->google!).
Are you sure your USB cable or port is not broken?

Okay, I have already tried that, since the USB got disconnected during boot loader flash, it does not display anything on the screen when I start with power button or reset combo. It only vibrates.
