but does not give me the phone serial.

thank you for the help

When your N1 is running as usual and plugged into your PC, ONLY the adb.exe 'devices' command will work.
When your N1 is running in "bootloader" mode, THEN the fastboot.exe 'devices' command will "see" your N1.

Usb Driver Problems

Ok. Right now I'm trying to root my nexus. I'm stuck at installing the usb driver. I tried following this tutorial /showthread.php?t=613217 but every time i choose the driver and it searches it tells me it "couldn't find a better match for my hardware" and the driver doesn't install. I've tried 2 different computers, a macbook pro dual booted with Win XP media center Sp 2 and a dell XP media center Sp 3. No luck with either of them. Anyone tell me what I'm doing wrong please? its getting really anoying

I'm having the same issue myself i think.
Look under N1 Q&A and find the topic "N1 Bricked"
Glad to know im not the only one
I have a iMac and I never even had to worry about drivers.
Just download/install/setup the Android SDK and the rest is automatic.
I have a tutorial called ADB 4 Dummies that will walk you through installing the android sdk 2.2(froyo) and setting up your environments. Step by step for every system.
First thing, unplug your Phone from computer, uninstall ALL drivers and try from scratch.
Also, if you're using windows, when you're done and you plug in your phone, don't choose to "automatically find drivers" instead manually point it to the drivers folder in the SDK.
Don't worry, it's not bricked. lol.

Hmmmm....
There are 2 modes to the bootloader HBOOT and Fastboot.
Make sure you're phone is in fastboot mode... it should say FASTBOOT USB highlighted in red on top. If it doesn't, use the volume down key, select Fastboot and hit the power button once to switch the phone to fastboot.
Remember, "adb devices" works while your phone is turned on regular. If your phone is in Fastboot mode use "fastboot devices"
Ok, are you using windows? If you are;
Turn off your phone and boot it back up in Bootloader mode. (trackball+pwr, or volume down+pwr)
Once it's on bootloader, plug it in to the computer.
See if the computer asks for any drivers, etc. If it does point it to the Drivers folder in the SDK. If it doesn't... go into your Device Manager. (Right click on MY COMPUTER, click on MANAGE and when computer management opens up, go to Device manager from the list on the left). Look to see if there are any icons with an Exclamation mark and yellow background. If there is, right click on it, select update driver and point it to the drivers folder in the sdk.
Basically there should be a menu on top that says "Android Phone" and when you expand that selection you'll see "Android Bootloader Interface".
nope, no luck with that either, I tried it both on windows XP and windows 7. same error each time. Could it be a problem with my device? because Snow Leopard doesn't recognize the nexus as a storage device or anything
Damn. I think i'm out of options. Last thing to try:
- Turn on phone regular.
- Plug in through USB to computer (try a different USB cable, even if that one worked with the CLIQ, try a different USB port also.)
- On Phone: GO to settings, Application Settings, Development, USB Debugging, (if it's checked on, check it off then on again) make sure it's ON.
Go into your Android SDK folder, go into the TOOLS folder. Now click on DDMS. See if it lists your device...
Last thing would be to go back through the Device Manager, and click on SCAN HARDWARE while your phone is plugged in... It has to be on that list somewhere, whether it's a bad driver, etc, it should still appear in your device manager somehow.
alright that didnt work, but, i got it, i just kept unplugging and plugging back in my phone until adb recognized it. then i got fastboot to run and now i have superuser . But now im stuck at another point. I'm trying to do the recovery.img file. I tried in mobile terminal "flash_image recovery /sdcard/recovery.img" but it told me something like "flash_image not found" I saw that i could do this via fast boot but i dont know how to do that. how would i do fastboot on Mac?
http://www.myhangoutonline.com/tutorials/nexus-one/6-upgrade-nexus-one-recovery
when i try to do the fastboot command i get "-bash: fastboot: command not found" i dont think i have fastboot set up right
have you tried typing in "./" before the command? I found that that was one of my mistakes I did when I first rooted my phone
tried that, entered "./fastboot-mac flash recovery recovery.img" and i just get "waiting for device"
I believe you can also try "./fastboot-mac flash recovery ./recovery.img"
Alright I flashed a clockwork recovery through the app manager in the market. Is there any way I can apply the other recovery with an update.zip?
Also, thanks so much for all the help guys!!!!!!!!!!
you can do it through terminal emulator, if you go to amonra's recovery thread he tells you how.
this is the link http://forum.xda-developers.com/showthread.php?t=611829
fastboot somtimes doesn't come in the SDK... download the version for your system from here: http://www.myhangoutonline.com/tutorials/nexus-one/5-unlock-nexus-one-bootloader
place it in your androidsdk/tools folder

[Q] adb devices doesn't recognize n1

Been trying to root N1(FRG83) without unlocking bootloader. Downloaded android-sdk to c: drive and downloaded usb driver.
When I boot the N1 into fastboot mode and type fastboot from the cmd prompt on the computer it sees the phone and gives me the serial (HT****)
When I try the same thing from ADB (ADB devices) it doesn't recognize the phone. I just get a blank line and go back to the command prompt. I've tried this on 2 machines (1 Vista the other Windows 7) and get the same results.
The frustrating thing is that I actually had the phone recognized with the ADB devices command when I first set it up but got called away from the computer and never had a chance to run the rooting routine.
Anybody out there solved this problem?? All help appreciated.
Thanks.
download and install the sdks and nexus ine drivers manually.
thanks but no luck
Downloaded drivers as you suggested but no luck. Also tried reinstalling sdk. Debugging is on, Java is installed, I'm out of ideas for the moment.

Del everything...restart your pc, and download the drivers and sdk..it'll take a few more mins.
When this happened to me, I restarted my PC and it worked.

If I recall correctly, adb won't work while the phone is in fastboot mode - and that fact that your fastboot commands work fine indicates that it shouldn't be a driver issue. Make sure you're running the adb commands when your phone is actually booted (at least to recovery).
If the phone is recognized by the computer via usb, but the adb does not see the phone connected, you just may need to simply delete and reinstall the latest USB driver that is offered.
There is actually an issue with Nexus One's where the adb composite interface doesn't work. It seems related to the issue with the broadcom driver and the mac address starting with 38.
See here - http://code.google.com/p/android/issues/detail?id=9437 - for more info.
I have now upgraded to frg83 and it works fine.

This. If you're running ADB in fastboot, you'll get nowhere.

[Q] Unlock Bootloader Problem

Hi guys, I have a problem.
I want to flash my N1 with the Cyanogenmod, but I have a problem with Bootloader unlocking. I do exactly what here is written (in the N1 guide from wiki.cyanogenmod), but when I open CMD (win XP) and write "fastboot oem unlock", it just doesn't works, but "adb devices" works and shows my phone. What can I do ? Any ideas ?
You need to boot into bootloader to work with fastboot. And if "adb devices" shows your phone - you obviously didn't boot.
adb reboot bootloader
Click to expand...
Click to collapse
Also, for a more comprehensive guide, please read the Wiki.
Code:
C:\fastboot>fastboot oem unlock
'fastboot' is not recognized as a
operable program or batch file.
This is what it shows in bootloader mode.
P.S. I have already re-installed my drivers. I have to notice that when I try to reinstall the drivers (in fastboot mode), they always auto-install themselves and when I try to update them, they say that there isn't newer version.
Fastboot executable isn't in the same directory as ADB executable, and isn't in the path you're executing it from (which is C:\fastboot).
Check, what is the actual executable you're trying to run, and if you have one. It might be called fastboot-windows.exe, if you didn't get it from downloading the Android SDK.
There is a executable file named "fastboot-windows.exe", but when I try to run it, it just open and close for 1 second. Any ideas ?
I thought the message would be clear by now... Oh well.
Open command prompt.
Run:
fastboot-windows oem unlock
Click to expand...
Click to collapse
I think It's done but my computer shows this message (see attached) 5 mins and I don't know it's ready or not ? Could I turn on the phone ? (Sry for the easy questions but I'm a real noob, because that's my 1st Android phone.)
The "too many links" message doesn't look good.
Reboot your computer.
Reboot the phone.
Use different USB port in your computer.
Ok well if you want my input try "fastboot devices" this should return your S/N (starting with "HT") if it gives you the same error then I would reinstall the SDK.

windows 10 and adb problem

OK, just got my nexus 6 yesterday, and said goodbye to Samsung..
first, plugged my phone into my windows 10 machine, and it instantly showed up in windows explorer, and was able to see all the directories on my phone, so that was good.
I then followed the instructions for installing the ADB/Fastboot installation stuff from here,
http://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
Opened the command prompt, typed in these commands, cd Desktop/android-sdk-windows/platform-tools
adb version, and adb version showed up just fine.
Turned off my phone, held down volume and power and entered fastboot mode, but after typing the proper commands, my phone serial number doesnt show up..
I have enabled developer mode, turned on USB debugging, enabled OEM unlock, but still no serial number shows up.
I'm not a rookie, and understand how to use ADB, but I am afraid that windows 10 is the issue..
Anyone have any suggestions?
Thanks for your input:good:
Mod Edit:
Solution found and thread closed at OPs request
You can't use adb in fastboot mode. You can only use fastboot in fastboot mode. Adb only works in android or recovery
thanks, I got it sorted out by installing this..

No ADB in Fastboot

I just purchased by OnePlus 3T and in the process of trying to unlock the bootloader. I have ADB while in stock oxygen os 4.0.2 but when entering fastboot to unlock the bootloader I no longer have access to the device. As per some searching I switched to a USB 2.0 port and still no luck. In device manager it shows my phone under "Other devices -> Android." I'm pretty sure i'm missing a driver for ADB, but can't figure out what is missing. Any help would be greatly appreciated!

Install, restart.
Specifically in folder you have adb files, hold Shift+Right Click, open command prompt.
fastboot devices to confirm connection
fastboot oem unlock to get started.
Search for the one plus 3t toolkit. It has the original one plus drivers.
Then install minimal adb and fastboot.
And it should work. If it doesn't, try on another pc.
Well it's been a while since my last new phone totally forgot to install USB drivers all good to go, newb mistake thank you!
or plug your phone into the pc and use the emulated cd drive that appears to get the drivers

After having my phone since Monday, I just now noticed that emulated drive when I had to nuke it earlier today, lol.
