I have a rooted LG Revolution and I tried to install fastboot on it but it failed so now the phone only boots to this screen
Code:
Fastboot mode started
USB init ept @ 0x3e000
smem ram ptable found: ver: 0 len: 6
fastboot_init()
Fastboot maximum download size : 450 MBytes
udc_start()
I think the solution on this site http://forum.xda-developers.com/showthread.php?t=1088046 will work but the device is not recognized on the computer (the drivers are installed). In the command line when I enter
Code:
fastboot devices
there is no reply.
What can I do to get the phone to be recognized? (The phone was recognized when the original ROM was working)
Thank you in advance!
have you installed the drivers for your phone? if not, they can be found here under step 2
Installed those drivers, still not recognized.

Daft one, but have you tried another USB cable?
No I have not, but when I plug it in a dialog box comes up with something like "Device Not Recognized" and on the screen of the phone it prints the
Code:
-- suspend --
-- reset --
-- portchange --
etc.
So the connection is made, just the computer doesn't realize it.
Again, when I enter the command
Code:
fastboot devices
there is no response.
I do have drivers installed.

I's be tempted to try the same on a different pc preferably with a different usb cable just to rule both out and ensure that the device is at fault not pc or lead

Recently switched to linux, installed android sdk, i can mount phone as an ext hard drive when it's on normally.
it's unlocked, i booted into fastboot, tried to use moto-fastboot and the device isn't found.
are there any additional usb drivers i need? i'm lost.
when the device is on normally and connected i get this:
$ adb devices
List of devices attached
???????????? no permissions
dont know if that would help but maybe usb deugging isn´t activated,
i havent unlocked my atrix but maybe there´s the problem.
just a thinking
thanks for the response. i checked at usb debugging is selected. it worked just fine on windows a few days ago but I don't have that installation anymore.
any motorola drivers i need installed? really stuck on this one.
Hi, I have already had my USB debugging enabled and from my device manager I can see my device there showing "ASUS Android Devices" > "Asus Android Composite ADB Interface".
But when I reboot my tablet as USB mode and from my laptop I run cmd as Administrator, and run "adb devices" command, it just show me "List of devices attached" and then the command prompt.
I have already unlock and rooted my tablet.
Why I can't see my device id ? Please help
Try: Connect/disconnect device from USB. Kill adb server (adb.exe) from DeviceManager, and then run "adb devices" again. Also make sure that correct USB drivers are installed for your device.

Yeah this process is correct. Even I've experienced this.
What I did is:
Removed the USB cable connection and reconnect.
Kill adb.exe
Restart adb.
Then device was shown to be connected.

Yes, I did that but still the same. Any other suggestions?
If on windows make sure your driver's are installed.
Type in cmd
adb kill-server
adb start-server
If that doesn't work try a different usb slot. You could also try moving adb and it's dependencies to your system32 folder. It's where all your commands are stored for cmd. You won't have to navigate to the android sdk tools.

it's so easy, just turn off your android device, then hold down both "Volume Down" key and "Power" at the same time, wait a few seconds till it start in recovery mode, done.
now type adb devices, and you'll see your device.
no need for that.
close any adb process either from task manager or by typing: "adb kill-server" in adb console
close everything and use this customized adb file I attached, it'll show your device.
it also has instructions and necessary files for rooting your device.

In your case just disable USB debugging and then enable again.
fix the driver
I had this issue.
In my case when I went to device manager I could see the Device and wasn't installed correctly and could not load the drivers even after having installed them on the PC.
SO I clicked update drivers.
Select that will chose the drivers to install and select the Android Devices - ADB driver.
You will get a warning, but just ignore it and load the ADB driver for the phone.
Ensure you are in the sideload option of the recovery
Now
adb devices
it should show up as Sideload
Now sideload
Cheers

It will definitely going to sort this problem..
For that just right click on adb driver ,navigate to detail tab and search for hardware id then add to adb.INI

Put your phone in PTP mode... just found this. When it was on charge or MTP nothing would connect, but when it was in PTP adb.exe said "error: device offline", but on phone it asked if I wanted to trust the computer!!! Ohhhkay, now we're getting somewhere. Clicked trust and ran adb devices and there it is
See below... I found there are two versions of adb.exe I was using. PTP is not the problem, but adb.exe has to be the right one or it just says offline.

ALSO!! Get the newest driver pack from LG "LGMobileDriver_WHQL_Ver_4.1.1". The driver packs in the roots that I downloaded aren't new enough. After Windows got the right drivers I was able to see the COM ports properly.
I'm not sure if I have the root working currently. The "Newest root method V03" where you click on root.bat seems to pick the wrong COM port. When I try to do it manually with Send_command.exe using the other COM port it seems like the root process doesn't work properly. It eventually completes, but no info about what it did etc.
I'm using an LG Transpyre VS810PP with Android 5.1.1 currently, and a Windows 10 64-bit machine.

Hello friend, try to connect to another USB port on your computer, if it does not work disconnect any USB devices you may have connected and try again, if still don't work is because drivers are not installed, try re-install them again, what windows version are you using, if it is Windows 8 there is special procedure how to install fastboot drivers,
Good luck
Yeah first make sure you see it in the Device Manager on Windows.

1- Hold SHIFT and restart you computer, always holding SHIFT or run this "shutdown /r /o"
2- You should be now on "Advanced Startup options", select "Troubleshoot" --->"Advanced Options"--->"Startup settings"--->"restart"
3- Next select option 7
4- plug your phone to computer in fastboot mode and install flashtool drivers, remenber to say yes on the windows appearing during installation, after everything is installed, restart your computer and problem solved.
As the title suggests, bootloader unlocked no problem, tablet was connecting to ADB at the time, tried to flash recovery which as far as I can tell was not successful (I can't boot to recovery, get the injured Android icon), now I can't connect to ADB (get the "List of devices attached" result). So I'm completely stuck, can't move forward, can't go back to stock, what do I do?
Edit: Apparently it's an issue with my PC, my wife's PC worked fine, why it worked to unlock the bootloader and then stopped I have no idea. Can anyone link me to a solution to get ADB working on my PC again? I tried removing/re-installing drivers, rebooting, you name it, no luck.
With your device booted into recovery or the system do you get anything in device manager? If you get a device with a yellow exclamation mark, right click it. Go to where it allows you to choose a driver from a list on your computer. Select adb android composite (or something like that)

Thanks for replying.
So before unlocking the bootloader, with USB debugging enabled I could get the tablet to connect using the ADB driver and could access it with ADB but could not access storage for file transfer, with USB debugging disabled and switching the driver manually to the MTP driver I could access storage but not ADB. I have had other device drivers installed on this PC for my Galaxy phones, I had issues initially with the tablet connecting but showing a yellow exclamation mark, then I removed all of the Android USB devices using USBDeview and installed the 15 second ADB tool to get it working, I'm on Windows 8.1 BTW.
After unlocking the bootloader, with USB debugging enabled I cannot get the tablet to connect using the ADB driver and but it does show as an ADB device with no yellow exclamation mark, I just get the "List of devices attached" result and anything that tries to access the device via ADB hangs or fails. I can still switch the driver to MTP and access the storage just fine.
My wife's PC is a Win7 box and has never had android drivers or ADB installed, I used the 15 Second ADB installer on her PC and the tablet works for ADB and storage access with USB debugging turned on, so there's something I'm missing that needs to be wiped out or reset on my box.
Hey everyone,
im trying to unlock the bootloader of my LG G5, but am unable to do so as the phone is not detected at all when in fastboot mode.
While it is recognized just fine as an adb device, after rebooting into fastboot mode via adb reboot bootloader it is not recognized as an USB Device in Windows (The device manager does not show any device with wrong drivers and does not react to replugging the device). I also tried it on a different machine with the same results.
Ubuntu also does not recognize the device at all, lsusb does not output the device anywhere. It also does get recognized as an adb device when booted up normally.
I installed the necessary (I tried LG and Google) drivers and tried different USB ports (2.0 and 3.0) and cables. The phone just is not noticed as an usb device at all when in fastboot mode.
Could this be due to a broken usb port? Which seems odd because the phone is recognized when not in fastboot mode.
What else could cause this weird behaviour?
Thank You!
Just to be clear. After you booted into fastboot mode, did you try
Code:
fastboot devices
and it just showed nothing?

Do you have usb debugging on because some devices require it to be on in order to be able to use fastboot on the computer.
In addition to ADB and Fastboot you have to install the "Android USB Driver" that is suitable to your phone, too, to get Fastboot working.
I forgot to mention that, oem unlock and USB debugging is enabled.
I tried installing the LG and android USB driver. But there is no way I can install these drivers to my fastboot device, as it is not recognized as an USB device at all, its like I'm plugging an USB cable with nothing attached to it into the computer.

The "Android USB Driver" is a Windows OS driver, hence it must get installed in Windows OS.

Yes i am aware of that. As mentioned i installed the driver, my phone is recognized as an adb device. I have seen some solutions suggesting installing the driver manually when the fastboot device is not recognized correctly but the device is not recognized at all. I also tried installing the drivers as legacy hardware (Android ADB interface, Android Bootloader Interface etc.) via device manager, which results in an error ( error code 10, device can not be started)
No more clues by me.
@holgers0n
I tried lsusb on my Xiaomi (I don't have lg) and it worked in fastboot also.
Since it doesn't show anything if you do fastboot devices, you could try to do the standard things:
1) Change usb port on your computer
2) Try another cable
3) If it's a usb type c, plug it into your smartphone, try if it works and if it doesn't, try around that cable and retry.
I am not 100 % sure but since you said
Ubuntu also does not recognize the device at all, lsusb does not output the device anywhere. It also does get recognized as an adb device when booted up normally.

I also had same issue. my redmi note 6 pro and asus zenfone max pro m1 can be detected in adb but not in fastboot. tried everything. changing driver/disble signature verification. also tried virtual box ubuntu/window 7. but not succeeded. It is actually an issue with usb 3. so I bought usb 2 hub. now everything works fine.

No, but i got it fixed with this AMD FASTBOOT FIX guide as i was using AMD Ryzen 5 5500U.
My laptop have both USB 2.0/3.1 ports hence it worked for me on USB 2.0 port (otherwise buy a USB 2.0 hub) after running that ".bat" file as "admin" it recognised my phone.
Keep in mind i uninstalled all 3rd party "adb tools" then rebooted my laptop and used Google's official Adb tool (approx 12mb) then ran "cmd" on the same path (keep the adb tool in :c drive)

Hello I have exactly the same problem. I know all the right drivers are installed, because I already flashed it from CN Rom to EEA ROM a few weeks ago. Usb debugging is activated, bootloader unlocked, etc . Nothing works.
Have you resolved the problem since?
Had the same problem after running:
adb reboot bootloader
Tried to run a fastboot command e.g. `fastboot getvar unlocked`, it gave the message `< waiting for any device >`
Solution
Assuming you have the bootloader driver installed, but its not connecting.
After running " adb reboot bootloader " with the device plugged in and in the bootloader follow these steps.
Open Device Manager => Win + R => devmgmt.msc .
Find the device called Android that has a yellow warning sign on it.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Open the properties and hit update driver.
Select "Browser my computer for drivers"
Select "Let me pick from a list..."
Select "Android Device"
(If this option doesn't show up, then you don't have the drivers installed)
Select Android Bootloader Interface
(If this option doesn't show up, then you don't have the drivers installed)
Click next and the the bootloader driver should be working.
This solution does need to be repeated when ever the device goes into bootloader mode i.e. when you want to run fastboot commands.
Mmm, just stumbled here to say that I had this problem since loong ago I unlocked the bootloader of my Z2121, and didn't know why. The reason is that I was using the Minimal ADB and Fastboot tool, because after reading the threads Bootloader driver issues on Windows 10? and [Tool] Latest ADB Fastboot and USB Driver installer tool for Windows subsequently, and of course using fawazahmed0's Latest ADB Installer, my problem was solved.
The BAT installer in the thread downloads the actual BAT installer file whose download path you can find inspecting it, and that other actual installer file for now sets the installation folder name as "platform-tools", and also adds its path into your system's user Path variable to allow running ADB and Fastboot commands from whatever folder location. For this reason you must also change the Path variable along with the folder's name if you wish to do so, or edit and modify the actual installation BAT file to change the folder name (there are a few entries).
Hope this is of help.
