Phone shows up in ADB but not fastboot - LG V10 Q&A, Help & Troubleshooting

I just got this thing and also my first LG as I've left samsung and I am a bit confused at this point. Normally not seeing it in fastboot was just go install the drivers which I did but still not getting anything. Suggestions?
Never mind hit it with a hammer and it's working now. Just had to fix it the old way to get it to show up.

I'm running into what sounds like the same issue as you. ADB found my device and Windows found the device drivers and showed the device properly in my Device Manager. Once rebooting into the bootloader Windows no longer found a driver that it was able to use hence when running "fastboot devices" nothing was listed. Once you get into the bootloader does your phone in the device manager show up as a usable device or a device with no drivers? I'm betting you're in the same boat as me.
I've trying different drivers but I've tried:
- LGMobileDriver_WHQL_Ver_4.0.3
- LGUnitedMobileDriver_S51MAN313AP22_ML_WHQL_Ver_3.13.2
- LGUnitedMobileDriver_S498MA22_WHQL_ML_Ver_2.2
- LG-Mobile-Driver_v3.14.1
- adb-setup-1.4.3
- Google USB drivers in the Android SDK Manager

Hey I got mine figured out. Hopefully yours is the same issue so here's what I did. The drivers that worked for me was "LG-Mobile-Driver_v3.14.1" which you can find by googling. After installing that Windows should see your device in the device manager which should allow you to run the adb command "adb reboot bootload." This will reboot the phone in the bootloader. When I checked my device manager, the phone only showed up as "Android." I had to update the drivers and then choose "show me a list..." and then choose ADB device. What's weird for me is that it showed me "Samsung ADB." I said eff it and went with it and it loaded and then I was able to run the unlock my phone with the fastboot oem unlock command.
I have no idea if that should have worked or not. Give it a go at your own risk tho. I'm by far not an expert so beyond what I've done, not sure if I could help you if you ran into any other issues.

Which Windows version are you using? Mine is Windows 10 and my device (V10 961N) still doesn't show up in device manager after downloading your recommended driver version?

I still have XP on my work laptop. While the phone was being recognized by ADB I couldn't get fastboot working either. It kept telling me that it was missing a couple dll files. Once I installed those it was smooth sailing. They're on a flash drive at work or else I'd tell you what they were.

Thanks. Would appreciate to get your help. I can see the device via the 'adb devices' command if I am in normal mode on my phone. Installed driver seems to work there. Doesn't tell me that I am missing any dll files. When going into download mode and seeing the Firmware Update screen the device does not show up in Windows. So am unable to go into fastboot.

Please, how did you fix this Issue ??? I'm having exactly the same problem with my LG V10 (H901)... I cant use fastboot commands, it just freezes and say waiting for any device... Fastboot doesn't see it but ADB does. Please Help!

I cannot get my h901 to get recognized in Fastboot Mode.

>>[HELP!!]Transformer Prime Stuck at ASUS Boot<<

Okay guys here's the dealio-
I recently got my transformer prime and I *loved* it. It came pre-loaded with the .21 version of ICS, which can't be rooted as of now so I downgraded to stock .15 with a modified ViperMod and then rooted and installed CWM. Next, I installed the Gummy custom ROM onto my prime (still .15). Well, I started to experience some weird -probably ROM related- issues and I ended up deciding to flash back to stock. ...BIG MISTAKE on my part I found out! I used the modified ViperMod to flash back to the stock .15 and it ran through the process but stopped at the ASUS boot logo with the little loading circle going around and around and around. First I let it sit for a VERY long time-stuck on boot. Then, I tried turning it off and back on-stuck on boot. Next, I tried pushing down the little recovery button-stuck on boot. I tried booting into CWM, but obviously, since I flashed back to the stock .15, all I get is the android guy laying in his side with the red triangle.
I am really really hoping that this is not a hard brick because the error that people are describing is the tablet stuck in the screen with "EeePad" in the middle and then getting something about an "unrecoverable bootloader error". My tablet boots past the EeePad screen and there is no error message-just the endless loading circle.
I am hoping that one of you smart guys could have a clue on how to revive my tablet. Any help would be greatly appreciated, and maybe I can buy you a beer if you bring my baby back to life
Here is a picture of what it looks like (circle is still spinning):

so you can get into recovery? I saw you said you tried to flash cm9 again. if you caught in a bootloop, jemaine made a zip file you can flash to get you out of it. you have to search for it though in developement section. does your computer still recognize your prime when you hook it up to your computer? you may need to adb commands into prime.
good luck getting it back running.

I no longer have cwm installed, it is just the stock recovery so I cannot install any .zip's. Also, when I plug the tablet in wile its on the Asus loading screen, the computer DOES recognize it. Maybe there is some way to get into it and reflash?
Any suggestions guys?

When you say your pc can see the prime can you see it with adb? If not go here:
http://forum.xda-developers.com/showthread.php?t=1426502
Once you have adb figured out you should be able to reflash recovery. See this thread:
http://forum.xda-developers.com/showthread.php?t=1576937
I used method 2. You will need to push the blob file to your prime using adb. Hope that helps.
Won't turn off and stuck on Boot screen PANIC!!!!
I'm running CM9 nightlies on my 64gb TF201 and have had no issues with it. I'm using GooManger and Teamwin for recovery and have not had any issues in that department either. Until now.
So 2 days ago a nightly was released that I flashed with out issues. The updated ROM however wanted to open the virtual keyboard when I started typing so I decided to revert back. I did this by just flashing an earlier released nightly. It went through the process and then restarted. The boot screen came on and then never left. If I try and turn it off it just restarts. I can't get it into recovery but I can get into fastboot. However I don't have a little Android symbol just the wipe data and USB. I don't have a backup on my computer that I can push through. I flashed CWM recovery through fastboot in hopes of then being able to get into recovery but with no luck. I used transformerprimerecovery.zip followed all the instructions got an "OK" and "finished" on CMD. At the same time the little progress bar on the TF showed that it did something but no change with my condition.
When I'm connected with fastboot it doesn't show up on my computer as I found to be expected. In device manager Android Phone is listed and when I click on it ASUS Android Bootloader Interface shows up stating device is working properly. If I open CMD and type "cd" it just replies C:\users\Josh>. I tried to wipe data to see if it would and it said it did but still no change. I've been reading for the past two days and haven't found the same set of problems yet. I've found similar issues but not all together.
Please if anybody has a suggestion for me I would be most Thankful. I've not had any luck with my searches
Thanks

I haven't been able to try this yet for I seem to be having ADB issues. SDK is updated and current and I have the latest universal driver setup. I show up in device manager but not in the CMD prompt.

I seem to be falling further down the rabbit hole. I mentioned above that I was able to flash CWM recovery via fastboot was not able to access it. I tried the same process with TeamWin recovery. It just stated that the specified path could not be found. So I'm losing features now.

When you are trying to flash anything in adb or in fastboot, put the file in the same folder as those .exe files. Manytimes it is a typing mistake on the path that kills you. Also remember to add the.zip at the end of the file name if applicable.

No luck. I've tried rearranging all the files associated with adb and fastboot I can think of. I've opened the CMD window from about every file as well as from the start menu and I can't get CMD prompt to recognize the tablet. The tablet allows me to get to the point where it states that it is "starting fastboot USB download protocol". Device manager shows Android Phone > ASUS Android Bootloader Interface. And when I remove the device it shows it listed as "fastboot device". I'm stumped on getting into CMD and can't do anything until I do. It just stays on the boot screen until I force it off. And if I'm not holding down the volume up button when I do it, it just recycles on. I've found post regarding the boot screen locked on but everybody has been able to fix it through a properly functioning fastboot/ADB.

The command window should be opened from the same window (folder) you have adb.exe or fastboot.exe in otherwise it isn't going to work unless you have the exact path which is easy to kame a mistake on. I would try the following:
If your not on twrp I would fastboot install it first.
Install universal naked driver
Download and unzip nvflash file
In the folder window where adb.exe is, press and hold shift, and right click and select open command prompt here.
Now do adb devices
You should see you device
put you rom in the same folder and push it to the table
reboot to recovery and install

[Q] Device not detected only on recovery mode

I'm trying to update my G Watch by sideloading a zip file.
I installed the sdk tools and usb driver as usual.
On debugging mode and bootloader, the watch is detected as an ADB device normally. 'adb devices' command works.
But when I reboot and get on recovery mode, the watch disappears on the device manager and never get detected again. So I cannot use 'adb sideload' command.
I've never experienced this kind of issue with smartphones.
Do you have any solutions?

I pushed the reset button on the back(the silver one right above the charging connectors) with a pen for about 10 seconds, and it rebooted.

Ok, does anyone know how to get my computer to recognise my watch in recovery mode? It's not about 'driver' the computer plain doesn't recognise that anything is plugged in at all.
I know the post is quite old already, but I experience exactly the same phenomenon...
I tried multiple PCs Linux and Windows,but non of them recognized the watch (neither on 4.4W1 nor on 4.2W2).
Anyone any idea?

The problem, as @osikiri stated, is that the device does not get recognized at all (no unknown devices in devicemanager and the sound that comes on plugging in a device does not come as well). Furthermore, afaik Linux does not even need any drivers

If this really helps (seems weird): I guess the exact setting could be necassary:
You simply ran out of battery while the watch was running(not recovery or fastboot) and then plugged it in and went directly (or not?) to the recovery?
Thanks in advance, would be really great to fix this!
Anyone ever find a fix to this? I'm trying to manually install the 5.0 update and I'm having the same issue. Every post I find with search tells me to update drivers but I'm on a Mac that doesn't even use ADB drivers. I've updated the SDK.

Yeah, same issue for me as described.
Windows (Win7 x64 for me) doesn't even realise that the device is connected when it is in recovery mode. Although it will connected properly when booted normally.
+1 Any ideas?
Same issue for me. I've tried removing and replacing it on the cradle, killing and restarting the adb server, entering recovery by the touchscreen or by the adb/fastboot commands, clearing debugging keys, etc... Anybody have any other ideas?

Ok, so it appears that the recovery img on 4.4w2 broke adb support or something. There are a few threads that suggest you can root and flash it or just wait for the OTA. We'll see whether I get the OTA before I have time to try this out.

I made a script that roots and updates your watch to 5.0.1 in a click.

I've similar problem, and I've spent almost 3 hours to find the solution. I found that following solution work for me:
http://forum.xda-developers.com/g-watch-r/development/manual-ota-update-root-t2969845
I've changed the step slightly according to the comments inside the thread:
- Enter Bootloader (swipe top left-bottom right as soon as the LG logo pops up on boot)
- Unlock bootloader (fastboot oem unlock) and boot the watch normally once
- Turn off and re-enter bootloader
- Flash 5.0.1 Stock Recovery (fastboot boot recovery.img)
// Do Not Flash 5.0.2 stock recovery
- Enter recovery and ADB sideload the update (tap the android, select install update from ADB and enter adb sideload filename.zip)
//you might have to reinstall the ADB drivers, just follow the simple step to install ADB driver
Done.
fi thought it was finally the solution, but fastboot oem unlock bricked my sony smartwatch3. I see tomorrow if with my windows pc i can fix with sony companion, otherwise i'll have to use the warranty

HP 7 VoiceTab 1321RA Bricked without Recovery or Custom Recovery mode accessable

Hi!
First off let me say thanks to R_a_z_v_a_n for redirecting me and hope that I'll find my answer here ^^
So I Have this device called HP 7 VoiceTab 1321RA (not with Slate just HP 7 Voicetab), wanting to have a custom recovery then I tried to flash a CWM Custom Recovery for HP Slate 7 VoiceTab because I thought it was the same and ends up bricking my phone. It ends up in a bootloop which only shows HP sign for a few seconds and dead. But I managed to find out that I can access the recovery menu (or so I thought it is), but the options was choosing between Fastboot Mode, Normal Boot, Recovery Mode, and VART Mode.
I tried to enter Fastboot Mode before and tried to access it via PC but somehow I can't find the device by entering adb devices and fastboot devices. Anyways, I have downloaded a stock update.zip for it but not the original KitKat one which I get from the first time I bought it but rather the JB ones. I think by flashing this would help me recover the device but the only problem is I don't know which method should I use to Flash it. Since I don't have the Stock Recovery or ANY kind of recovery at all, I guess I'm stuck. And it won't start to the home page so I can't set the USB debugging options. Please guide me through this >.<
Thanks a lot!
Been fighting with it for 2 days now and still no result came.
So here's the update so far....
I tried on my other device in order to understand how my PC reads ADB and now I kinda gets it. But the problem is now can't get the device to enable USB Debugging because I can't access options at all.
Secondly, since I left it on for the night because charging seems to trigger the bootloop too, now I can't access the fastboot mode like I was last night. And it constantly repeating this sequence: [battery scene with the "charging battery" symbol] > [HP Powered by Android screen] repeated for 2-3 times > [low battery need charging screen] > repeat. And once I tried to connect to the PC, it goes to the same sequence too. When I tried to access the boot options (the screen which displays Fastboot Mode, Normal Boot, Recovery Mode, and UART Mode which I mention in Thread Starting post), it shows the low battery need charging scene and then repeating the same sequence as mentioned above.
I seem to figure out how to fix this but I still can't manage to access the fastboot mode yet. Will give update once I can try to.
Anyone can help me on this?
Thanks a lot!
Update!
Somehow with a little tweaking and stripping the device, I managed to solve the charging problems. Will update on this once my problem finished.
Jump out from the frying pan and into the fire so they say, I ran into another problem. Finally managed to get into fastboot mode, the devices manager reads it as an Android Device>ROMaster ADB device like the other device I tried to connect while in ADB mode and fastboot mode, but somehow CMD cannot read the device as an ADB device or a Fastboot device like the other device did. I tried to uninstall and reinstall the driver and still nothing happens. I tried to find the usb_driver on the internet and it directs me to the update.zip instead. Trying to update the driver via Computer Management but it says the driver is up to date. Now thinking about making an emulator device based on the HP 7 VoiceTab 1321RA but I really have no idea how to make one. Any one have any idea of what should I do next or can guide me through this? At least until the CMD can read the fastboot.
Thanks a lot!
I found my self in a deadlock!

Attempted to install custom ROM, now watch is stuck in infinite boot

I downloaded the recovery image, but I can not flash it do to Windows not recognizing the watch is connected. ADB gives me the error Device '(null)' not found. I have checked the device manager and there is nothing showing as an error (yellow !). Is there anyway I can recover from this?

The watch is showing CSC Fastboot Mode! So I would assume that it is in Fastboot mode
Were you able to get this fixed?
No, I have but been able to resolve this issue. It is not being recognized by Windows, therefore I can't flash the original os back to it.
Did you have TWRP installed prior to the failed flash?

I may have a way to get it working. I've had issues where Windows would not recognize a device, until I installed a cocktail of random drivers that eventually worked. What version of Windows are you running?

I am running Windows 10 X64 build 1803
If you have the space, follow this: https://docs.microsoft.com/en-us/windows/wsl/install-win10
It allows you to run non-graphical Ubuntu on top of Windows. I've found sometimes my Windows 10 PC won't recognize things with adb or fastboot, but it works great in Ubuntu Bash. If you're familiar with Ubuntu at all, then it'll be a breeze to figure it out. If not, it's a pretty straight forward learning curve. It's also child's play to get adb and fastboot working right in Ubuntu, whereas it can be finicky in Windows.
Another alternative is to make a Linux Live CD using a USB drive, but that is a much more temporary solution.

If none of those sound appealing, then I'd suggest deleting all drivers having to do with adb or fastboot, and start fresh by installing everything with this https://forum.xda-developers.com/showthread.php?t=2588979

OK, I will mess around and see what happens! I will have to do it tomorrow, but I will play around and see what happens!
Let me know how it goes and I'll walk you through it some more.
Any luck?
Sorry for the long time to reply. I installed ubuntu in window and installed the appropriate packages, however both ADB and Fastboot show nothing connected, even though the device is in CSC Recovery mode. Is there anything else I can try?
I actually tried playing with a few things on one of my computers the other day to try tracking this down. I was running into an issue where adb worked normally when the watch booted, but it would not work in recovery, and fastboot did not work either. Here is how I fixed it. Open up device manager in Windows and delete any driver pertaining to Android phones or adb. In my example, an Asus driver was causing the problem. I deleted that and reinstalled the generic Google drivers using the 15 second adb/fastboot installer that I posted in this thread. After restarting the computer, adb works perfect in Android and recovery, and fastboot works perfect as well.
TL/DR Delete all Android adb drivers in Windows, then run the 15 second adb installer that I posted in this thread, restart, and get your watch back to normal.
Assuming your bootloader is unlocked, you can flash everything I have posted here to get it running. https://forum.xda-developers.com/zenwatch-2/development/sparrow7-1-1debloat-rom-t3800067 If the bootloader is not unlocked, fastboot oem unlock will do it.

OK, I got windows to see the watch via fastboot and I downloaded the image that you posted (bloat free) now the watch started to boot, but so far it is just showing spinning dots, and has been for ~5 minutes or so, is this normal?

[Q] can someone provide me a guide how to unlock bootloader. i got some problem here

i tried to do it my self. follow an instruction from a official website and other
https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/
https://www.getdroidtips.com/how-to...-plus-i3213-i4213-i4293-i3223/#Pre-Requisites
which i got stuck at, when i boot into bootloader mode . the phone seem to restart and appear only black screen with blue indicator.
then i tried to check if it still connect to adb or not, with {adb devices} its not listed there
PS.
-the drivers work fine
-my Xperia 10 plus model is I4293
The LED is all you get. The screen stays black for fastboot and flash modes. Not sure why adb devices isn't working.

one thing weird
i using a Xperia Tool (Xperia Companion) and it display the text that my phone need to unlock the screen or allow to use data tranfer
which i already check a USB debugging to be on, and every time i connect it to my PC, it still ask me a permission to be allow or not
maybe this is a problem here ?
It cant be listed in ADB if the android isnt running.
Blue LED means fastboot mode. So to check if the device is in that mode you do "fastboot devices".
Once the LED is blue you can unlock the bootloader with the command "fastboot oem unlock 0x<insert your unlock code>".

When I pressed to volume up button and plug the cable in, led turned red>blue>off. I tried releasing the button at a different colour, but my phone still did not go into fastboot mode. Did I do something wrong?

I guess you are using windows. This is issue on windows when you don't install adb drivers. There should be tutorial on Sony site how to install them.

Yes, I am using Windows 10, but let me clarify my understanding first.
From what you said, I need to manually install the ADB driver by Device Manager > Portable Devices > Xperia 10 Plus > Browse my com... And that driver, I should get it from Sony site, but I only see Xperia 1, 5 and 8, not 10 nor 10 Plus.
However, I could see my phone by using command adb devices through minimal ADB and Fastboot. Does this imply that the driver is installed already?

Adb and fastboot are not the same thing so you have to get fastboot driver.
I have no clue where this driver is as I use Linux only which includes the driver by default.

I see. There is a fastboot driver on Sony site, but it was uploaded since 2014. I successfully installed it, but still nothing seems to work. I will try on Ubuntu later. Thanks for your help.

I was using windows 10. From what I can remember, my problem is that I didn't install driver correctly (I'm not sure which one). I am not really sure if this fastboot driver the one I used. I saw my device in Device Manager, but I got waiting on device... just like you. So what I have done was locate my device in Device Manager and install the sony driver over that device. If sony's driver was not the correct one, then it was another driver that I can't remember, but the instruction still the same. Sorry for an unclear message, but I can barely remember anything now.

Go in Windows Device Manager and check the device . If needed install drivers manually
