Phone not recognized while in bootloader, works fine when booted into ICS.

Attempting to unlock the bootloader of my brand spankin new LTE G.Nexus. I installed the samsung USB drivers, am running Windows 7 64bit. Made sure USB Debugging was on. When running ICS issuing an 'adb devices' on my windows machine shows the device there, and I can remotely reboot it into the bootloader, however as soon as it goes into the bootloader (via manual reboot or remote) I loose USB connectivity, it shows up as an unknown device in my device mangler and ADB no longer see's it.
I've tried uninstalling/reinstalling the driver, reboots, etc. Can't figure it out. Anyone else having the same issue or have any ideas?
TIA!

im having similar issues...im stuck in "waiting for device" in the bootloader.

I'm having the same problem and nothing I've found helps. Since I really want to unlock the bootloader, and doing so wipes the device, I'm stuck not being able to do anything with the phone until I get this worked out

I had this problem when I was unlocking the bootloader. I kept playing around with it and reinstalled the drivers multiple time. I would uninstall the driver and install the driver when the phone was in bootloader mode (I believe).
Make sure the drivers you're setting it to are new.
http://dl.dropbox.com/u/4174784/usb_driver.zip were the drivers I used. These are for GSM model, not sure if they work for the CDMA/LTE version!
Alternatively, you can install PdaNet for drivers.

I finally got it to work. My problem was that I didn't have an updated driver for the device in bootloader mode. This is how I fixed it:
1. With your phone connected and in bootloader mode, go to your computers Device Manager (Control Panel -> Device Manager)
2. You should see an Android 1.0 device. Right click and choose Update Driver.
3. Choose Let Me Choose From This PC (or whatever it's called)
4. Click on Let Me Pick From List.
5. Choose Android Device
6. Choose Android Bootloader Interface
That's what worked for me.

Some people also had luck by installing the windows pdanet which installs drivers that should work too.

Thanks buddy!
Worked for me, I thought it was due to my HTC/Motorola device drivers, so uninstalled all of those and re-installed the Samsung...but these steps worked. Thank you again (I did also hit the thanks button too FYI!)!

That method didn't work for me either. I'm running windows XP professional and do not see 'Android Device' in the list of devices... any other ideas anyone?

Did you download the Google USB drivers as part of the Android SDK? They're at the bottom of the list of things to download when you open SDK, that's what I did.

I did,
Tried the PDAnet method as well. Adb works fine. Once I get into the boot loader the device isn't recognized. I get the Android 1.0 install prompt and cant install it.

Thanks! FWIW, I had to uninstall the Samsung driver and use the Google USB driver to find the Android Bootloader Interface one... if others are having trouble, try that.

[Q] samsung drivers wont install

hey.
i followed the guide for rooting my galaxy nexus.
driver installation was alright, and then i switched to fastboot mode (green android) and then the device manager didn't recognize my gn (unknown device).
tried uninstalling and then reinstalling, tried "updating" it with various rar files i found on this forum and ofcourse i tries pdanet.
none of them worked. it was always unknown device.
then i had no choice and i removed the battery to boot it normal.
suggestions? thnaks

After installation, plug in your phone, look at your system tray for the USB icon, click it. It should show a status of installing more drivers. This can take awhile, and for a lot of people it seems to fail the last step, Android 1.0 drivers. Open control panel, system, device manager. Look for a yellow error icon. Click that, choose to install drivers manually and locally. Then select 'choose from list', find Samsung.
That should get you back on track

Were you able to unlock the bootloader? If you didn't do this, don't go installing any driver... be very careful. If you install the wrong driver in device manager, you'll screw it up. I installed the wrong driver on my main computer and I couldn't get the device manager to even recognize the phone :| I couldn't locate the right driver either because once I installed the driver, it renamed it. It was a huge pain and the only way I got this to work was by using a different PC with the correct drivers.
I have found this to be the best instructions for unlocking the bootloader. Most importantly, it includes directions on how to gain access to adb on your phone properly. Take your time and follow the instructions exactly...

I had the same issue, install pdanet and your phone will be recognized when in fastboot
Sent from my Galaxy Nexus using xda premium

i followed one of the main guides on this forum.
it says to install the pdanet drivers and then boot to fastmode via the volume buttons.
once i got into fastboot, the device was unrecognizable.
when i was still in normal boot, the device was recognized and it was all right. and yeah i turned usb debugging on.
how can i unlock the bootloader without installing drivers?
thanks

silly question, but after booting to fastboot, you are using the fastboot.exe, and not adb? if you type "fastboot devices" does anything show up?

no, nothing shows up.
and thats clearly because the driver is not installed correctly.. i see a yellow sign in device manager.
what am i doing wrong? only thing i was different from the guide is that instead of typing adb reboot bootloader, i got into fastboot by pressing the volume buttons.

click open that yellow unrecognized device...manually choose drivers (don't do auto), and select from the list, you'll see samsung, choose the driver
that should install android 1.0...alot of people have gotten this error.
edit: another thing to keep in mind is, after installing the drivers, and fixing the device in device manager, it can still take a little bit to initialize. in your system tray there should be a usb icon, open that to see when the drivers are done

I am in the same boat. I tried for hours on 2 different Windows 7 laptops (both 64bit). I am trying to get Yakju from one of the derivitives (without unlocking the device).
Steps taken:
- Dloaded Samsung USB driver 1.4.6 & Installed: Did not recongnize in explorer or Odin (even Odin did not show a thing)
- Dladed PDA Net A302x64: Did not recognize in explorer or Odin.
Both times the GN is in Device/Printers and listed as having Android 1.0 driver. I try to manually update, but cannot seem to find driver in list (as it just has Android 1.0 driver listed). Any suggestions?

i didnt even see the "Android 1.0".. just "unknown device" all along..
i also tried on a different computer.. same issue.
about manually installing the driver.. i tried pointing him to a manual driver package i got from this forum.. it said its the same driver..
when im searching for "samsung" on the list, i dont see a relevant driver.

Well, i've saw someone else on here who was having driver issues, who also had installed both samsung & pda drivers...
uninstall both.
fresh install ONLY the naked drivers directly off samsungs website (http://www.samsung.com/us/support/downloads/verizon-wireless/SCH-I515MSAVZW -- if you're verizon, if not, you can search there). Do the install. Plug the phone in, it will start to install its usual crap. this is the long part. then, it will fail like you saw before. in device manager, you'll see the unrecognized device. Open, it will ask you to find drivers, choose "Browse", "Let Me Pick From a List", "Samsung", and then pick the driver with the date 11/25/2011
check to see if there are any other unrecognized devices in device manager, just to be sure you got em all. at this point, plugging in your phone should show the USB connected icon in the system tray. do you see this? If you click it does it say "Eject MTP"?

[Unrooting] fastboot does not detect OP3, while adb does

For the past few days I've been trying to pass SafetyNet with root and after I failed, I tried to unroot my phone as passing SafetyNet is more important to me than having root. In the processing of doing so, I messed up some things on my device. I flashed all uninstalllers of SuperSU, Xposed, Magisk and other stuff I flashed through TWRP and deleted all SU files in bin and xbin. It removed root but I still wasn't able to pass safety net. I then messed up somehow and removed my TWRP and now when I try to access recovery it simply boots up my phone. I decided it would be the best to simply reset my phone using fastboot and adb (maybe even lock the bootloader again?). Fastboot however, cannot detect my device while abd can (not in the bootloader menu though). I have searched arround on the internet, have installed tons of drivers, reinstalled the SDK + Android Studio,... but I can't seem to get it work. When my device is booted up, it shows in Device Manager as "ONEPLUS A3003" and when in fastboot mode, it shows as "Android Bootloader Interface". Updating the drivers doesn't help. Would love if someone was able to help me out here!

The problem is the last update windows 10. You need to connect your phone in fastboot mode to your PC. Then go to the Device Manager, find there KEDACOM USB Device, clicked and appears in the ANDROID BOOTLOADER INTERFACE. Click on it right mouse button, put the Update Driver Software, then search for drivers on the computer, then select DRIVERS FROM THE LIST and select FASTBOOT INTERFACE (USB GOOGLE ID).

Got it working with your help! Had to completely remove the drivers first and than put my PC into flight mode though, because Windows 10 would keep reinstalling the drivers. Thanks for your help!

If you want helpful responses you have to be more specific. Assuming you have the fastboot files installed on your PC/laptop ... What LG G4 model? What software version? Bootloader Unlocked? etc.
Assuming you have installed on your PC/laptop LGMobileDriver_WHQL_Ver_4.2.0 available for download from the LG US site as the Windows driver can create issues, have you tried downloading and installing the "Official" TWRP app and installing that way?
Suggest if you are still having problems, you head over to: https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424

I have the right files, when I get into adb reboot into bootloader
it no longer recognizes the device. I cannot flash twrp

After reboot into bootloader, open your "windows device manager" and see if windows detects your device properly.

Don't allow Windows 10 to update your drivers - you can set that up in Windows. Google it for the how-to.

The device type changes depending on "how" its connected. Windows can "see" it as a ADB device, MODEM, etc...
With the phone connected, uninstall all device related on windows device manager, refresh the device manager for it to detect the phone as it should be (as you need it to be detected).
Sometimes its needed a manual device driver install. Happens some times to me, unfortunately I don't remember exactly how I do it because the issues (when it happens) are kind of random, so, I need to "understand" what is going wrong and fix it.
Just to tell you that is nothing unfixable on the procedure, you just need to have patience and find out how windows is supposed to detect your device.
If you don't find out by yourself, tomorrow (Monday), I'll try to see on mine how it should be detected in fastboot mode and tell you. Today its already late for me...
Good luck

Your device should be seen as "LGE Android Phone" (if your lg drivers are good).
Now gonna be tricky because my OS is in Portuguese, I don''t know exactly the path name in English... use your imagination
Connect the device on a USB 2 Port !!!
In windows device manager, select "update driver", "search software on the computer", "allow to choose from a list of avalable drivers". unmark the "compatible hardware" and find on the list the needed drivers. If the "LGE" drivers don't work, try to download Universal ADB Drivers, maybe it works.

I'm thinking it could be a corrupted LG driver. Download another from the LG US site, ONLY. Uninstall the one you have installed now, reboot and install the newly downloaded one. Then connect your phone and see if it is recognized and shown correctly in Windows Device Manager. Also, in adb type lsusb and see if the phone is listed in the output.

Question Fastboot problem

Hello people,
I'm trying to unlock the bootloader following the sony instructions,
but i cannot configure correctly the drivers on my windows 10 machine (with last updates 22H2),
when i connect the phone on fastboot mode (light blue led turned on), i have on the device manager under other devices "android" with a warning sign.
when i want to update the controllers to the ones that i downloaded from sony or the google ones (as instructed by sony), windows says that cannot find any compatible controllers...
if i manually install the controllers from sony, i got them with a warning and code 10 (cannot initiate).
when i used EMMA to verify the phone (volume down, green led) the phone get recognized... so i'm pretty sure it's not a problem of port or cable.
HELP?
i don't know how to proceed.

I haven't try on win 10 with 22H2 but Google : disable Windows verificirano drivers. At one point in time that was solution for me.

Please download drivers from here and then move the file to desktop and open it as admin and install the drivers.
If your computer has AMD or Intel Chipset, please make sure you have all the drivers updated to the latest ones because the chipset drivers do cause these problems, You can use iOBit Driver booster free software to update your Windows machine drivers.
Please comment if you need any help in this regards.

Solved.
I did a install of generic ADB drivers of google (with the controller update), and that worked for me.
