ADB doesn't work for my Galaxy Nexus

Hi,
I realize a lot of people might have the same problem as I have, but haven't found the answer after searching for many hours. So here's my problem:
windows vista x64
installed android SDK and all related drivers
GN is recognized with correct driver in both fastboot mode and regular "on" mode.
GN is recognized as a device in regular on-mode with 'adb devices'
GN is recognized as a device in fastboot mode with 'fastboot-windows devices'
HOWEVER, when GN is put into fastboot mode, NO devices are found with 'adb devices' even though the icon for 'safely removing hardware' pops up with 'Android ADB Interface', which means the driver is correctly installed.
Someone please help explain why the device is not recognized by 'adb devices' command under fastboot mode even though it's recognized by the computer!
Summary:
GN is found with 'adb devices' for normal boot, but GN is not found under 'adb devices' for fastboot mode. I have reinstalled the android ADB driver, but still the same problem.
I am stressed out! Please help me

I have noticed exactly what you are talking about however what I have found is that it doesn't seem to need to be able to respond to the adb devices command. I was still able to unlock,root and flash multiple different boot.img and radio.img files through fastboot without the computer returning the device while in fastboot. Hope this helps.

P.S. while you are in fastboot mode it seems you may be looking for something different than standard adb commands. Fastboot is primarily used in this situation so a command for you will typically look something like this"
fastboot-windows flash boot boot.img
or
fastboot-windows flash radio radio.img (the radio.img and boot.img files used in these examples you would want located in the same folder as fastboot-windows)
if you want to try the software out without flashing it "permanently" try:
fastboot-windows radio radio.img (just forget the flash portion)
for unlocking the bootloader the command will look something like this:
fastboot-windows oem unlock

ADB isn't used in fastboot mode, fastboot.exe is.
ADB is for when the phone is running Android or recovery only.

Phone doesn't recognize ADB in fastboot
Phone doesn't recognize ADB in fastboot - have used every conceivable method - downloaded Samsung drivers. Downloaded PDANet. Uninstalled Samsung and tried Naked Samsung. I got the phone unlocked. But I CANNOT get the PC 64 to recognize ADB when I am in fastboot. HELPPPPPPP. I've been working on this for TWO DAYS, and it is RUINING my Christmas holiday.

Have you tried the driver installation/troubleshooting section of this post?

Unfortunately, yes. I tried the Samsung drivers. Then I tried the PDANet. I also tried the Samsung naked drivers. I was sure that MSKIPS toolkit was going to work, but when I typed in "2" for rooting, NOTHING happened. I'm at my wits end.

Of course it doesn't.
AS STATED MULTIPLE TIMES IN THIS THREAD, YOU MUST USE FASTBOOT.EXE.
Please, read thread then reply.

When phone is turned ON - use adb
When in FASTBOOT mode - use (surprise surprise) fastboot

When phone is turned on or in recovery - use adb (check it with "adb devices" ,without " in cmd)
When in FASTBOOT mode - use fastboot (check it with "fastboot devices" ,without " in cmd)
In order to work fastboot you must have the fastboot.exe preferably in the same folder with adb

Try this
I tried installing PDAnet but no Joy.. but went to device manager and selected adb drivers and samsung from the list and that did the trick...

Can you ADB push files to the sd card without an OS installed???

I just accidentally wiped my SD card and my system and now I don't know how to get a rom onto my phone due to the lack of an SD card slot. Can anyone help me get a rom on the internal so I can flash? I have TWRP still but I have no clue how to get a rom to my sd card. Am I screwed? Cause I read a forum that had to have usb-debugging on and I have no system lol. Thank you guys so much

You dont need USB debugging tot have adb in recovery. Just use adb sideload. Or adb push.

Could you give me the commands to adb push a rom to the phone? I can't get adb to recognize my device in fastboot either When I use the fastboot devices command no devices show up... it's depressing

First use TWRP not fastboot. Once you are in recovery plug the phone in and type "adb devices" (without the quotes) in command prompt or terminal. If it returns with letters and numbers (can't remember might be a combination of both) your good to go. Type "adb push c:\downloads\Rom.zip /sdcard" type out the directory where the file is instead of downloads change it to where your rom is. If you type adb devices and nothing happens you need to work on your drivers.

I had this issue - I couldn't get the computer to recognise the phone when it was in the Bootloader. I had to uninstall all the android drivers I could find (using this: https://www.topnotchtablets.com/FixUSBproblems) and then plug the handset back into the USB while in bootloader.
Let it detect it as a generic device (or whatever it chooses to see it as, mine was different every time), then in Device Manager, right click it, then select Update Driver Software. Select the option to choose the driver you want to install and navigate to where you have the drivers saved. The actual driver is: android_winusb.inf. Choose the option select the driver yourself from that file, and locate the one that says Bootloader.
After doing all of that I was able to see it all fine, and it was detected in fastboot, and all the toolkits I used.
Someone feel free to correct me anywhere I'm wrong - just going from memory here.

He said he can't get adb to recognize his device - isn't that because the drivers aren't installed properly? I know adb and fastboot are two separate things. If the device isn't showing after he enters "fastboot devices" then my first guess was that the phone, in bootloader (since he has no OS installed), isn't showing up in device manager either because the drivers aren't there.
Excuse me for trying to offer thorough assistance...

Sorry if I sounded like a Douche. I might be wrong but I thought adb and fastboot had separate driver sets.

No worries - it's possible that they do. But the drivers I linked are the ones that worked for me consistently. The Samsung ones seemed to stop working each time I disconnected the handset and plugged it back in via USB.
In any case, those are the only ones I have installed right now and everything is working great for me connection/recognition wise.
Any luck yet jtl_777?
To push files to the handset, use the command: adb push filename.ext destination-folder

Just for future reference so people reading these threads don't get super confused, your computer won't recognize your phone through adb commands unless you are in adb sideload through your custom recovery, or if you're booted up and running in an operating system. You could also use adb push commands in your custom recovery. This has nothing to do with drivers or whatnot. If in bootloader your device isn't recognized through adb commands, that's completely normal, because it never would be, but your device should be recognized in bootloader with fastboot commands.
IF your phone is NOT recognized in your booted up phone, or in adb sideload through your custom recovery, or with adb push commands in your custom recovery, with adb commands, then you have driver issues.
ALSO IF your phone is NOT recognized while in bootloader, with fastboot commands, then you have driver issues.
To answer the OP's question:
If you have an unlocked bootloader and you are in TWRP, you can mount your phone onto your computer and copy and paste the rom zip onto the phone and then install it through TWRP once on the phone. If that doesn't work, then you can try using adb push commands while in TWRP (or maybe need to be in adb sideload through TWRP) to push the rom to your sd card and then run it through TWRP. If that doesn't work, you can also try flashing the rom zip through bootloader with fastboot commands, but all these commands might be device specific, that's why I won't tell you the commands I know for the HTC One X, but the processes are the same no matter what. Hope that helps

You don't need to be in sideload mode to use adb in recovery. I use adb in recovery all the time on all my devices to push files

I believe that's if you're using push commands, no? Other than adb push commands, can you use other adb commands while in a custom recovery, without adb sideload?
For the sake of clarity, you cannot use any adb commands while in stock recovery, but you could if you have a custom recovery.

[Q] adb/fastboot can't find device in bootloader, but they can do it when booted

Dear all,
I have worked on building Android from source code for few weeks. It used to be fine to me with my galaxy nexus, I can connect to my device via adb and fastboot and flash either the factory ROM or ROM built by me into my device. However, when updating the phone into 4.3, I forgot to extract drivers into the built directory and flash the built image into my device. Is surely can't work, and the screen turn off once "Google" is shown, so I would like to reflash it back to other image. However, my laptop can't recognize my Nexus S anymore in the bootloader. I can use "adb shell" once the device is normally booted (even without screen), but once I type "adb reboot bootloader", the connection is lost! Both "adb and fastboot devices" show nothing....
I have searched the forum and stackoverflow all day but can't find helpful information. There are many threads talking about unable to connect devices but 70% of them are driver-related issue and 30% of them, ex: sudo adb, just don't work for me. I think I am not facing the driver issue because I still can use "adb shell" once the device is normally booted (not in bootloader mode). Moreover, I also tried few debrick tools contributed by xda community but with no luck.
I am wondering if there is any way that I can reflash image to my device without accessing it in bootloader mode? (ex: push image in to device via adb shell when device is normally booted?). I am also wondering if there is any way to fix this problem. Any suggestion is very appreciated!: crying:
Thanks
Yu-Chih
ps. the most closed thread I found is called "ADB can discover devices but not fastboot" in stackexchange (I am not allowed to post the link)
but it seems there is no answer in this thread

I'm not a expert, but do you know how is the DD command ?,
I wonder, is you can DD the boot loader into the nexus partition?

Thanks for the reply. I am not sure what I should do with dd command? Could I use it to reinstall the drivers into device?
by the way, I found there is a error showing up in the bottom of screen in fastboot mode, "Fastboot Command Read Error -2147483647", and many closed threads (sorry that I am not allowed to post url because I am new). Some suggests are to reinstall drivers (even thought I don't get if they mean reinstall the usb driver for laptop or for android), but it seems not solved yet.

Dear all, I think I have tried all potential solution about "fastboot command read error -2147483647" that I can find at internet......
Here is what solution I have tried:
1. sudo the command of adb and fastboot
2. update drivers
3. update sdk
4. use another cable
5. install other drivers (win7), ex: naked driver
6. Wug's root kit
What I can't try:
1. enable USB debug mode at phone (because I don't have screen of it but only adb shell)
2. remove(uninstall) other software such as PDA net...etc (I don't try this because my system is clean-installed win7/MAC/ubuntu)
I think this problem is kind of common but my situation seems slightly different from others, that I can find the device when my device is normally booted but I can't recognize it when it is rebooted into bootloader (showing "fastboot command read error -2147483647" at bottom). I am starting to believe it either be the problem that I don't activate the USB debugging in my new flashed image (but I can connect it with adb when the device is normalled booted) or the usb driver in my device is broken.
Anyone has any idea.....:crying:

Dear all,
This is my latest update. I wipe out the whole system of Ubuntu and Win7 and restart everything from the first step. Magically, the new Win7 + Wug's root kit can successfully flash new image into my phone. But also magically, the ubuntu system faces the same issue as I described (no connection in bootloader with the error code but connection is fine after the device is booted). The bright side of this is that I am finally able to try other solutions, e.g., enabling debugging mode, but the sad part is that I still get no luck at Ubuntu and MAC.........can't believe it works at Win7 but not at Ubuntu and MAC.....

fastboot never start after update to android 6

Hy
I had an unlocked bootloader phone. Yesterday I flashed the new Android 6, Europe version from the Huawei blog forum, no beta, on my Huawei GX8. I used the method, dload on SD card, Phone off an the press Volume down+volume up+Power button.The flashing was normaly.
Now the phone starts normaly but I can´t start fastboot. When the phone is off and i press Vol down + Power the phone start the android system and the Huawei logo is coming not the fastboot Modus. I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!

Should be connect the charger cable to the phone.
charger or computer
excuse me for bad english

No i use a data cable, debugging is on. I can copy data from my phone to PC or from PC to phone, but fastboot does not found my device.

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.

i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.

Phone must be in MTP mode.

And here is phone in fastboot

Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

Just reboot to fastboot and flash surdu-petru version of TWRP recovery 3.0.2 with command "fastboot flash recovery xxxxx.img". And than reboot to recovery and flash supersu zip.

(help please) htc one m8 not showing in adb command prompt while in fastboot.

so I'm trying to fastboot flash TWRP. That way I can root it after the custom recovery is set up.
My HTC is S-OFF, I installed android studio for the adb fastboot command prompt. Then installed all HTC drivers. I then plugged in my HTC into my pc which is running windows 10 via USB port which are 3.0
I opened up the folder where the fastboot was installed when I downloaded android studio. Then I pushed shift and right clicked and chose open command promp. I then typed: adb devices
The command prompt runs and it shows my HTC in the device list. Then I typed: adb reboot bootloader. It boots to the fastboot.
And so here is my problem........... once I boots to fastboot I thenjoy again type: adb devices. Cmd runs and the device list is blank. I checked my drivers and device in device manager and everything is fine. Even I'm fastboot it reads the drivers no problem.
I've tried everything. I've read to try reinstalling the drivers, try installing universal drivers, try different USB cables, try different USB ports that arent 3.0 port, I even tried a different adb fastboot software and still came up with the same outcome. I've read a bunch of different threads and just can't find anything. I am just stuck I don't know what to do. And am asking for help please. I would really appreciate the help and guidance. Because....... this s**t is driving me crazy haha. I've rooted galaxies and have my s5 on lollipop rooted. But
I'm still a noob and especially with HTC. So please some one lend me a helping head I am at a complete loss.

You're using the wrong command.
You can't use adb commands when booted to bootloader, only while booted to system, as you did the first time.
Once you do adb reboot bootloader use fastboot devices and your phone will show in cmd. You need to use fastboot commands while booted to bootloader.
