For some reason i am unable to push the commands to my phone. Following this guide:
http://wiki.cyanogenmod.com/wiki/Nexus_One:_Full_Update_Guide
When I type adb fastboot devices it just displays syntax's that I can add to the command rather than doing what its suppose to.
Anyone?
Btw does radio become a concern with Nexus one? It was with the G1/Dream.
Follow the guide correctly. There is no "adb fastboot devices", you're not reading right. It's either "adb devices" in ADB mode, or "fastboot devices" in fastboot mode.

I can get adb to recognize the device using "adb devices". I reboot to bootloader via the command "adb reboot bootloader" and I get the screen with the 3 little guys on skateboards and it says "FASTBOOT USB" in a red box, but when I type "fastboot devices" it just blinks and goes back to "c:\adb". Then if I try to run a command it says "<waiting for device>". Any help is greatly appreciated. Thanks.
I tried to root my kindle through, http://forum.xda-developers.com/showthread.php?p=24128777 , but I got half way and got stuck at the fastboot mode. I don't have recovery or anything because it was a stock 6.3 kindle fire. Does anybody know how to get out of this? The adb isn't recognizing my device right now and I've tried hard resetting.
Any help would be appreciated!
Edit: Is the only way out of this is through a factory cable?
what means got half way ?
you switch to fastboot at a point - then adb commands are not recognized
only fastboot commands are recognized in fastboot mode
would try to issue:
fastboot -i 0x1949 getvar product - it should return "kindle"
if not check your drivers
if you got the drivers working resume with the above manual
about drivers:
http://forum.xda-developers.com/showpost.php?p=22342376&postcount=6
Oh. Is that it? . So is it normal for the cmd command "adb devices" to not show the kindle device?
If so, that's a pretty big relief! And all I need to do is type that cmd?
you have a great manual here explaining how the kf works:
http://forum.xda-developers.com/showthread.php?t=1552547
furthermore this one could help you to understand how drivers/bootmode/commands correlate:
http://forum.xda-developers.com/attachment.php?attachmentid=943772&d=1331571368
I'm having a similar problem. I can boot into fastmode but when I try to reboot, it just seems to hang with a <waiting for device> message. I get the same <waiting for device> message if I do the fastboot -i 0x1949 getvar product command.
I am stuck in TWRP and if I hit reboot, the command prompt does return the info.
OK, it appears that the KF didn't update. It was just stuck in some weird boot loop or something. Maybe it was trying to update and couldn't for some reason? I am keeping all this info bookmarked in case something does happen though.
So my dad went out and bought a nakasig/tilapia it's running Android 4.2.1 and bootloader is 4.13. Having just updated my razor/flo via fastboot everything was setup and working. "adb reboot bootloader" reboots the nakasig/tilapia into fastboot mode and "fastboot devices" shows the nakasig/tilapia serial number. Every other fastboot command just hangs there and does nothing. "fastboot oem unlock" does not prompt me to unlock bootloader. "fastboot reboot" doesn't even reboot the tablet. I use Linux so I figured I would try Windows following the thread sticky'd in this forum http://forum.xda-developers.com/showthread.php?t=2175086 same problem adb works fastboot will list the device but can't do anything with it. "fastboot getvar all" did give me an error however "FAILED (command write failed (Unknown error))" all the other commands just hang there doing nothing saying nothing. Having tried Windows and Linux setups which I have used on my other Nexus devices without issue I am starting to think its an issue with the bootloader maybe I need some older version of fastboot.
Is there a way to flash bootloader from inside Android or Recovery? I can use Towelroot to root the tablet then flash TWRP from Android and boot into TWRP but I don't think you can flash a bootloader from there or unlock the bootloader can you?
Edit: according to http://forum.xda-developers.com/showthread.php?t=2068207 the nakasig/tilapia bootloader is encrypted so you can't flash or unlock it without fastboot.
OK so you have a 2013 N7 that does not have this problem, but your dad's 2012 does. Two different pieces of hardware.
Could it be a driver issue? Sometimes when the drivers are not talking to it correctly you get these flaky results. Different USB cable/port?
Theoretically there is a flash all command you can use to flash an update of the whole thing including the bootloader without it being unlocked. However if you are getting write errors then you should really be cautious because that could just fry it instead of fixing it.

ADB and fasboot use the same drivers don't they? While in Anroid adb works fine I can adb shell I can adb push/get I can adb reboot.

No, AFAIK they're different drivers, and different devices often require a distinct driver install too.

Got any sources on that info?
WOW
weird! really weird!
I really don't know what the issue, the fact that it happens on Linux and on Windows makes me think to an hardware realted issue, unfortunately..
As long as I know adb and fastboot do not use exactly the same drivers, but you download and install them together, so it should n not be a problem, this one..
The only think I can suggest you atm is to try with Linux by logging in as superuser (su). On my slackware with my "normal" user adb works as usual, but if I try to use fastboot the terminal says me No permissions..
I hope someway your distro has the same issue, even if your fastboot devices success!
So login as superuser and try to use fastboot. If you do not install it in /bin partition you should have to locate its directory and then use
./fastboot devices
or any other command but with ./fastboot instead of fastboot..
hope it helps.. I really hope!!
For that matter, on a whim... when you open a command prompt in Windows to adb to your device, try running Command Prompt as an Administrator. Sometimes Windows is weird like that.
Please keep questions in the Q&A section. Development sections are for development only.
Thread moved to Q&A.

hi All
I had a nexus 5 earlier. I have used adb and fastboot to install custom ROMs. My adb setup is fine.
I have put Zuk in dev-mode,
The following command works, The phone reboots.
fastboot -i 0x2b4c oem unlock-go
None of the other commands work
adb reboot bootloader
I have even tried to put phone is bootloader mode, manually using keys, and then tried to run adb commands. Even then it didnt work.
Do you think it can data wire issue, or am I missing some settings.
Running Mac OX El Captian.

you need to add ./ infront of any command on mac.
like this
Code:
./adb reboot bootloader
the same goes for fastboot commands.
like this
Code:
./adb reboot bootloader
I am doing that already.
I restarted my phone this evening, and when it booted up I got a "decryption unsuccessful" message. When that happens it appears my only option is to flash a factory image. So I download the most recent image, and when I get into the bootloader I see no option for fastboot.
When I'm in TWRP (3.0.2-0) I can see my phone listed in recovery or sideload when I run "adb devices" from my computer, but no devices are listed when the command is run while on the main bootloader screen.
Not sure if it matters at this point, but I had the 20160821 Pure Nexus build installed when this happened.
How do I get my phone into fastboot mode so I can flash the factory image?
Thanks so much for your help.
It sounds like you may not have the latest drivers for the Android SDK or ADB toolkit.

When you are in bootloader, you can use fastboot commands.

Not sure what you're talking about. Turn the phone off. Hold vol down + power, to boot into the bootloader / fastboot.
Run the fastboot devices command, and you should see your device. That's where you can flash your system images.

So, if I'm at the bootloader's main screen, I should be able to see my device when I run the command "adb fastboot devices", right? Cuz that's not happening. Also, when I use the volume rocker to see the available options fastboot isn't listed.
When I go into recovery from the bootloader and run the command "adb devices" I see my device listed with "recovery" next to it. When I launch ADB sideload from TWRP, I also see my device listed with "sideload" next to it.
So, I can run fastboot commands when I'm in the bootloader even if "adb fastboot devices" returns nothing?

It's not adb fastboot.. It's just fastboot.

The problem I have is that when I'm in the bootloader (at the screen with the android robot on its back) and use the volume rocker to see the available options, fastboot isn't listed as an option to select.

It's literally, stay in bootloader
type: "fastboot devices" and you should see your device.

Thanks. I'll do as you said and report back. Maybe what I'm doing wrong is recalling the bootloader unlock procedures where "adb" precedes some of the commands when executing them from the Windows command prompt.
Just to be ridiculously clear it's:
1. While unplugged, Power + Volume Down to enter the bootloader.
2. Once in the bootloader connect USB cable.
3. Navigate to the SDK platform-tools folder, and from the Windows command prompt execute "fastboot devices". Then I should see my device listed.
Sorry if I'm being dense.

or plug your phone in (while its booted normally, into its OS)
type: adb reboot bootloader
once phone reboots to bootloader, type: fastboot devices
He must have came from a HTC bc he's looking for the option Fastboot in Bootloader.

Thanks for your help everyone. I'm back up and running now. My problems stemmed from a misunderstanding that once in the bootloader I'm already able to execute fastboot commands and didn't need to select a fastboot option from the bootloader. And I had a misunderstood how to execute the fastboot commands from the command prompt.
Many thanks to everyone setting me straight!
