[Q] adb can't find my D800 after OTA on rooted - AT&T LG G2

Hello,
this is my first post here.
I recently rooted my LG G2 AT&T (D800). It was running D80020y.
Also recently AT&T offered the update to Lollipop (D80030f). I did not accept the update but ATT pushed it anyway when I rebooted the phone.
After that the phone would not boot, it would just go into recovery mode. I have TWRP v2.8.5.1.
Many of the posts addressing situations like this require installing the D800 drivers in computer, and installing adb.
I am trying to solve this problem from a PC running Windows 7 Pro. The PC is not able to see the device.
"adb devices" returns nothing. Not an errror, but an empty list.
When I connect the G2 to the PC, the (windows) device manager lists it twice:
1) Under "portable devices there is an entry "LG-D800", and there I get "this device is working properly", and it uses Microsoft drivers under C:\windows\system32\ and under C:\windows\system32\DRIVERS.
2) Under "Other Devices" there is an entry like before, "LG-D800", with an error sign. When I open that entry I get:
"The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.
To find a driver for this device, click Update Driver."
Even if I click "update driver" and navigate to the installed LG drivers they won't load. The PC says that nothing was found.
I've tried this also on Windows 8.1 with the same results.
However, with the phone plugged into the PC I can see its contents with Windows Explorer, and I can copy files into it.
I just can't run adb or fastboot.
Of course, I am not able to change to "USB debugging" mode because I can't boot the phone. For the same reason I can change to PTP mode.
So the larger question is how to get my phone back to booting, and I've seen references to that in xda-developers, but all of them use adb,
and for that I need the PC to be able to see my G2.
Thanks!

Can you access download mode?
By powering off your phone and then press and hold volume up button and connecting usb from your pc.

I don't know what Download Mode is but I tried what you suggested. It took me to the same place, i.e., it loads TWRP. TWRP seems to be fully functional.
Thanks for answering

Go to LG and download the latest USB drivers and try connecting again.

Thanks for the answer. I had tried that and it did not change the results.
However, I don't really have more time to devote to this. I have spent a lot of hours during the last week.
I thank for the answers though.
How do I close this thread?

Computers blind to NS4G. Help?

Hey folks.
I have been trying to get my wife's NS4G back to stock to get the JB OTA. I have downloaded all drivers multiple times on multiple computers (windows). I have tried 3 or 4 different USB cables. I have downloaded pdanet. I have downloaded the JAVA SDK and updated everything about it.
My computers cannot connect to the NS4G.
USB debugging is on. When I try to turn on tether, it tells me USB is not plugged in.
I have been able to restore the stock ROM (2.3.7) via CWM, but now I no longer have a recovery. It is still rooted and unlocked. Rom Manager is installed and it will not download CWM Recovery.
I need some way to get a recovery onto it. CMW or stock.
Does ANYONE have any suggestions?
Thanks in advance for all suggestions and particularly to the one that will work.

If you are running Windows 7 hold down the shift key and right click then select open command prompt here. type ADB devices and if your drivers are installed then you will see your serial number. Remember to be in fastboot when you install drivers. then use ADB to reboot bootloader. when in fastboot type "fastboot devices" and you should again see your serial number to know that your drivers are all installed correctly. You need to fastboot flash a new recovery image. Hope that helps

Drivers are installed, as I can see my S3 fine as well as adb getting my serial number. The computer, nor adb, can see my NS4G. I have tried a desktop as well as 2 laptops.
Will be trying Vaelek's idea of wireless adb this evening.
Thanks for the suggestion.

Drivers are NOT installed properly then. Drivers are installed on a per device basis. If your phone doesn't get recognized, then they are not installed.
Chances are your device ID isn't found in the .inf file of the drivers. I know back when I rooted my phone over a year ago I had to manually change the inf file and add my device.
If you start your phone in fastboot mode and plug it in, when you go in device manager you should see an unrecognized device with a yellow question mark. Right click it, then Properties, then Details tab. Give me the information in the Device Instance Path.
Will check this out and post info when I get home tonight. Thanks for the input.

Started phone in fastboot mode. Plugged it in and watched Device Manager. Closed device manager and re-opened it for a good refresh. I get nothing new. No unrecognized device and no Android Device like when I plug in my S3. ADB Wireless wont connect.
OK... I just cleared my sd card and was able to install CWM. One hurdle cleared...
I still need to get stock ROM and recovery. Is there anyway to do this WITHOUT being able to connect via adb?
Thanks again for any input.

ADB won't work

Hi all,
Before explaining what the problem is, I want to state I have searched Google, XDA and various other websites to solve it myself. I do know the #1 rule of XDA
Today I've tried to use ADB Sideload to install a rom on my Nexus 5. I've done this before one time, when I accidentally formatted my entire phone, and it worked. Currently my phone is in TWRP Recovery, and ADB does recognize my phone when I type in 'adb devices' in the command prompt. However, when I click ADB Sideload on TWRP to sideload the rom from my laptop, the phone disconnects from my laptop (I hear the 'ding' from Windows), and I can't sideload anything at all.
I did update all possible drivers (ADB and Google), tried all USB-ports available, and even tried another laptop, but nothing worked.
Can you guys help me out, or provide new information about the issue?
Thanks in advance
With your device connected to your pc and booted into to twrp, go to device manager on your pc. Do you see an icon with a yellow exclamation mark? If so go to where you can choose from a list on your computer. Choose Android adb composite driver.

Or just scrap off adb. Download stock img's from Google and fastboot em in bootloader to get your phone up and running again

So far I did this, and ADB finally allows my phone and laptop to sideload files (so thanks a lot). I did install two seperate roms at two seperate moments via sideload, but after booting up and showing the 'android' logo for a couple of minutes, the screen stays black (for both roms). I know the first boot takes a while, but this never happened to me before, and the phone won't start up anything further. Any new ideas?
Edit: tried it again with a third rom, and this one does install completely (Cataclysm, with AROMA). Even my laptop recognizes my phone and automatically starts Dropbox, but the screen stays black. Did I kill my phone?

To get into download mode you need make sure phone is 100% powered off then hold the volume up button and then plug in the usb cable. Dont release the power up button until the phone is fully in download mode not just the first screen. Also search for your phones adb drivers and install them to your pc not just the usb drivers. Make sure to uninstall any existing drivers first.

Did you try another pc with the adb drivers installed to see if you get the same error? If it connects on a different pc try this on the problem pc.
Open task manager
Click on the Hardware tab
Click the Device Manager button.
Expand Universal Serial Bus controllers section.
Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
Restart the computer, and allow the computer to reinstall the USB controllers.
Plug in the your phone in download mode and test to to see if the issue is resolved.
You can also download Ccleaner and fix any registry errors for free. I've used it for years and it works really well.
Still no joy. Try a system restore on your pc sounds like the device management could be screwed up.
All kinds of funky sh*t can happens when a pc crashes. You said you have windows 10 as a last resort you can do a system refresh which reinstalls the os but keeps your files.

Everything you need can be found here in the LG G Stylo forums and if it's not here a google search will help.
You need...
MetroPCS 5.1.1 KDZ
LG drivers
LG Flash Tool
Download the KDZ. Install the LG drivers while you wait for the 1.2GB KDZ to be downloaded. Download the LG Flash Tool and when the KDZ has completed downloading run it as an administrator. Settings in Flash Tool should be fine. Point to the KDZ and begin the flash. Normal or CSE. Normal does not wipe data, CSE wipes all user data. You'll be prompted with something about your internet connection. Do not close this, the tool should be flashing the KDZ. Wait for the phone to be rebooted after flashing. Profit.

I had the same problem once the device connected as download mode.
The kdz tool doesn't detected and crashed all the times. But miracle happens I kept playing(open&close)the kdz tool app. Somehow it detected and flash the kdz.
Android Studio was a bust still unable to find my device even with the code to direct information to the only USB device connected

I was under the impression that the phone was entering dl mode but just not getting recognized by the pc. Either or you should bring it to a corporate store and tell them it boot looped while updating and play dumb. They should replace it since its under warranty. Or call lg and do it that way although its about a ten day wait.

My phone does enter download mode just can't do anything from there. ADB can't find device. I even found the port I'm in and tried to force into recovery but still no device connected.

Moto G USB Problem

Greetings, everyone!
Okay so a few days ago I fell asleep while using my phone, a Moto G 2014 (XT1068). At one point I wake up to see a window saying something along the lines of 'Updating X of X Apps" on a black screen. I put my phone on my bedside table and fall asleep again. When I wake up, the phone's off so I assumed it was done doing whatever it was doing (which I now think it was some sort of system update), so I turn it on only to find out it gets stuck in the Motorola logo loading screen. I've left it like that for maybe an hour and it's just stuck there. I've accessed Fastboot to try the Recovery option but it just returns a 'Boot Up Failed' message and if I choose the 'Factory' option (which I assume is a factory reset), it also gets stuck in the Motorola logo loading screen. The other options are 'Normal PowerUp', 'Barcodes' & 'BP Tools', none of them doing anything either. Upon some research, I figured it was probably some sort of update that crashed down the whole thing and that apparently a way to solve this would be to flash the phone with the Stock ROM, which I've already acquired (and hopefully it's the right one). Now, thing is, I need to connect my phone to the computer, which is running Windows 10, while on the Fastboot menu. This is where the problem comes in. I never enabled USB Debugging in the settings. I've also installed the Motorola Device Manager from the Motorola website because apparently it installs the drivers for the phone, but after installing the MDM countless times, I just don't see drivers anywhere. I've checked the Device Manager on Windows and there's no track of my phone's drivers in there whatsoever. There's no 'Other Devices' tab anywhere and my PC doesn't do that "device was plugged in" sound effect when you connect something through USB. I've downloaded ADB Drivers and different versions of Motorola Drivers but nothing seems to work. I've tried 6 different cables in 10 different ports, still nothing. The phone charges but it's like the PC doesn't detect it. While on the Fastboot menu, according to a few videos I've watched, it is also supposed to say a USB Cable is connected when you connect the phone to the computer, but even though my phone is connected to my PC, that never shows up. I don't know if this is because the drivers might not be installing on my computer or if it's because I never enabled USB Debugging in the settings. I've seen some people say it doesn't need to be enabled while in Fastboot but I don't know if that's true or not. So I'm pretty much out of ideas at this point, do you think something might be done?
Thank you in advance,
- Nervly

Hey, thanks for replying!
I did, but it wasn't recognized. I also tried 'adb devices' but it just returned an empty list of devices attached. Any other commands just returns <waiting for device> and I'm guessing this is all happening because the drivers might not be actually getting installed (considering there's no track of them in device manager) and/or because my PC doesn't detect the phone as connected through USB (even though it is). The PC doesn't play the sound effect of when you connect something to it and the fastboot menu doesn't display the message "USB Cable Connected" (or something along those lines).

I'm off to a job interview right now but I will try the disabling drivers signature method you suggested once I get back.
As for the device manager, showing hidden drivers still doesn't list the phone's drivers or the 'Other Devices' tab, sadly. Perhaps after I disable the drivers signature enforcement and try to install the phone's drivers again it will work. I'll keep you updated!
Thank you for the help thus far!

Alright, I just got back and tried to disable the drivers signature enforcement thingy but it sadly still didn't work. The drivers still won't show up on the Device Manager and my phone still won't be detected by the computer. What's weird is that it seems like the drivers are being installed because there are some .sys files related to Motorola in my C:\Windows\System32\drivers folder but nothing will detect them.

Fastboot drivers aren't same as USB drivers
They differ so if you want to work with fastboot you need fastboot drivers

No green android when using flash or fastboot mode

Hi,
First of all the bootloader is already unlocked.
Two problems:
1. - I was trying to flash twrp.img on my mobile but I am not getting that green android to show up in my screen all I get a black screen with blue led light, I usually power off the mobile, hold volume up and then connect the USB cable to my mobile.
2. - Can't find mobile device while using flash or fastboot, my mobile Developer option and USB debugging are turn on, mobile drivers and adb-setup-1.4.3 are installed, I have access to my mobile on my PC , when I do the process of flashing or fastboot I turn off the mobile and I unplug USB cable from my mobile, I press the keys to do flash or fastboot (I don't see no green android just a led light turn on) and connect the USB cable, problem is my PC can't find the mobile device, I use adb function eg. adb devices or fastboot devices I get nothing no device no info.
Is this problem with Win 10?
Was my problem understood in 2. - ?

Most likely a drivers problem, Windows10 fails to tell you that it's not installed the drivers that you pressed the install button on. It also fails to assign the right drivers when you add the phone in flashmode/fatsboot.
You will need to add them manually.
Go into safe mode and use 'driver signing disabled', try adding the drivers again. Then plug in you phone in flashmode/fastboot, then look in the device manager for the phone and change it
Several people have reported success with Zdiag drivers

Thanks! Great Info.
I removed the drivers manually in device manager and then used Zadig, now in command mode I getting something.
Next I have to figure how root the phone, do I need to flash twrp.img ?
I have all this stuff and I got confused which one I need to do next:-
boot.img
boot-G8141-47.2.A.10.45-hideunlock-rooted.img
twrp.img
twrp-3.2.1-0-maple
xperifix.zip
ss_maple.zip
zestmaple-latest.zip
