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.

Help GNex has no OS and won't connect to a PC!

Windows 8.1; but had same problem with Windows 7 computer.
USB device not recognized
The last USB device you connected to this computer malfunctioned. And Windows does not recognize it.
Windows has stopped this device because it has reported
problems. (Code 43) A request for the USB device descriptor failed
Tried using WUGS Toolkit to install drivers, not happening.
The phone charges via usb port with no problems
On top of that, daughter wiped phone, there are no ROMS, or usable backups.
I can get into TWRP Recovery, but it can recover what isn't there. Tried factory
reset, still nothing. No matter what I do, I get No OS Installed! Are you
sure you wish to reboot? If I do reboot, just get GOOGLE screen with lock
symbol.
Without being able to get a computer to see the phone, I can't get a ROM to
load.
Maybe change USB port with cable? But I don't want to do that if the problem
is software related.
Any ideas what I can do???

I just went through something similar like this last week, what a pain in the A$$.
Not entirely sure if this will fix your issue, but hopefully it'll help some how.
I ended up having to manually install galaxy nexus driver so I could sideload a ROM since I formatted my internal storage to test out this new F2FS BS... Anyways.
LOL
First you'll need to download and unzip "universal naked driver 0.72" Google it.
Now, without your GN connected open device manager and THEN when you plug in your GN to your PC you should see it pop up in the portable devices section.
AND also under other devices there should be "galaxy nexus" right click on it and click "update driver software"
Click "browse my computer for driver software" select the unzipped universal naked driver folder, click next and click "install this driver software anyway"
Now it should show "Google galaxy nexus ADB interface" in device manager under Samsung Android Phone.
Reboot GN into bootloader
OR
recovery (if you have a ADB supported recovery eg. TWRP 2.7.0.0, and enter ADB mode)
Now there are 2 ways to do flash an Android OS, some may find 1 easier then the other:
download/install "Wug's Nexus Root Toolkit aka NRT v1.8.3.sfx"
Google it.
Run NRT and it'll instruct and guide you through the steps required and whatever is needed to continue, eg. Select device, download TWRP 2.7.0.0...ETC.
Or
Download/install ADB setup 1.3
Google it.
I found this method a little more simpler.
Open the folder you have your ROM/gapps zip files saved on your PC, hold down shift key and right click on the folder, click "Open command window here"
Now in the command window type in "adb sideload XXXXX.zip"
XXXXX = COPY/PASTE the ROM file name. Eg. 20140615PA443RC2.zip
Press enter and now it'll flash the ROM onto your GN.
Repeat the same steps for gapps/kernel zip files.
Reboot your GN and enjoy.
BTW
I'm still loving running ParanoidAndroid Jellybean 4.1.2.

Its like pain in the A** to install phone/adb drivers in win8/8.1
I had a similar issue with my gNex a while ago but i had the drivers installed in my pc so it wasn't that difficult.
Why don't you try to install this toolkit http://forum.xda-developers.com/gal.../gnex-toolkit-v11-1-0-drivers-backup-t1392310
When you run the toolkit, it may ask you to select your device, build number etc and also about installing device drivers.
Install the drivers through it and then connect the device in recovery (twrp) mode.
it should detect it and then you can push files/roms to sdcard (internalMemory) using adb push or the built in options in the toolkit.
then flash the rom and you're done
and i recommend using win7 or xp or vista for doing this because the driver installation in win8/8.1 is a bit difficult compared with other previous windows versions but there is still a way to install drivers in win8/8.1 its just a lengthy process
All the best :good:

OK, downloaded universal naked driver 0.72, connected gnex, but it only shows up under Universal Serial Bus controllers as Unknown USB Device (Device Descriptor Request Failed), not under Portable Devices, and will not allow install of of universal naked drivers, & yes I have toggled to allow win 8.1 to installed unsigned drivers. Since I cannot get phone to turn on to full android, it is not recognized. Any other suggestions?

You have to go to the device manager, double click on the "unknown usb..."
a dialog box may appear and then click on the 'driver' tab.
There u may find update/install driver button.
click on it and another window may open.
then select browse my computer for driver software and go to the respective folder where the drivers are.
then click next and it may install the drivers.
if you have installed the toolkit then you may find a folder in the toolkit's installation folder which has drivers in it.go through it if you want :good:

Unlock bootloader - "waiting for any device"

I got my OP3 today and am trying to unlock the bootloader. I've tried every tutorial and toolkit out there but they all get stuck at the same point in adb, "waiting for device". The "adb devices" command works fine but anything else gets stuck on "waiting for any device". I've tried googling the issue but none of the suggestions have worked so far. Any input would be great.

did you enable oem unlocking from developer options?

bro you may be running win 10 and to connect fastboot on that u need adb driver which u will find on windows update all u have to do is just connect your phone with data transfer mode and update the window 10 . ull find something name qalllcom its adb drive or i dont but after that it will like charm.

I have all the necessary developer options checked. After futzing with it for hours, I tried a different computer (also Windows 10) and it worked right away. I'm going to see what the driver issue is this evening because I still would like to use the original computer I was using. Thanks for the replies!

for bl unlock, you need to be at fastboot mode, and installed right driver, for me working any of stock Google USB package fastboot bootloader driver.

Go to fastboot mode and do "fastboot devices", then try unlocking bl.

I've tried everything including disabling driver enforcement on Win 10 but I still have the same issue. I have the wrong drivers installed. I've tried uninstalling and reinstalling the drivers but when I plugin the phone, the wrong drivers get installed. I got it to work on another Windows 10 computer and below are device manager screenshots of the working (with right drivers) and not working (with wrong drivers) computers. I have no idea how to get the right drivers installed on the computer where its not working and unfortunately, its the primary computer I use.

Try this:
Connect the op3 to usb port - don't bother changing from "charging"
Right click on "ADB Interface" in dev man and disable it.
Without unplugging the op3 use the buttons to reboot into bootloader.
Hopefully W10 will now detect your op3 and either load the correct "oneplus" driver or create a new entry in dev man of Other Devices > Android Composite ADB Interface. Right click on this and then Update driver software > Browse my computer.... > Let me pick... > and if you're lucky One plus will show up in the manufacturer column and allow you to select the composite interface

Okay so this is the problem. I figured it out 2 days ago.
check the bootloader driver when you're in fastboot. Right click it and update driver, it should be the Android Bootloader 9.00, and not Bootloader 11.00
it's a silly weird fix, but it should be under Android and not Kedacom
I was using the Android SDK Studio Platform Tools and Google Drivers provided from SDK Studio

Similiar to the previous users post I'll try and be a bit more clear.
unplug your device if plugged in.
boot in to fastboot mode on your device.
Go to your PC and access device manager
plug your device in and you should see
"kedacom" instead of android interface
now inside you wanna click update driver
browse my compute for driver software > let me pick from a list of driver software > "Android adb sooner interface"
if its not that exact one check for the one that does say adb interface.

I created a bootable USB drive with Linux Mint to solve my problem. It was Windows 10 that would recognize my OnePlus 3 in "Fastboot Mode" with Kedacom drivers.

Can't get windows 10 to detect my Fastboot device

hey guys, I just got my OP3, I want to open the bootloader before I store some data that will be erased anyway when unlocking, I enabled USB Debugging & OEM unlocking & Advanced reboot and then I accepted the RSA Fingerprint popup. (Then, when running adb devices, I got the id of my device).
Now, I am in bootloader mode, and when running fastboot devices, I get nothing. I already installed Oneplus drivers when first connected the device.
In Device Manager under Other Devices I can see a device named "Android". When trying to install the drivers manually by browsing devices I have on my computer, I can only see "Samsung ADB Interface" and I am afraid installing this will not work when trying to unlock the bootloader. What can I do? I also have a Kali Linux Laptop if that's helping. Thanks.

Put in fastboot mode, connect to computer and manually select fastboot interface from the device manager "install device/update driver manually" box. That worked for me.

Can't unlock bootloader - fastboot issue

Hello,
I am trying to unlock my bootloader but I my computer (Windows 10) does not recognize fastboot.
When I connect to fastboot (holding volume up button + connecting my phone by USB when it's off, or using the adb reboot fastboot command), the computer does not recognize the phone. I then tried installing drivers (both from Google and Sony) by going into device manager but Windows just doesn't install the drivers.
I then saw this on Sony's website:
Fastboot driver - Sony Developer World
developer.sony.com
So I download the file and pasted it instead of the same file (android_winusb.inf) in the Google driver folder, and it somewhat worked, but Windows said something like unable to find drivers for ADB.
I also tried to install in Windows test mode but to no avail.
No matter what I tried, entering the command fastboot devices in fastboot mode does not give me any output (not even "waiting for device").
What am I doing wrong?
Thank you!

Did you already disable driver signing? Pretty sure you have to do that with Win 10. I would disable driver signing, and then use " 15 second adb installer" from XDA. Always has worked for me...
