Fastboot Troubles

I just recently got into modding my N1 a few weeks ago and finally hit my first snag:
Original root was through superoneclick, so bootloader is still locked. I flashed over to stock GRI40 OTA without realizing (stupidly) that flashing
it would also flash over my RA recovery and unroot my phone. Now, superoneclick is incompatible with GRI40, so I can't re-root through that, and I'm having trouble
with unlocking the bootloader through fastboot.
I get no response from ADB or fastboot in windows cmd prompt when I boot phone to FASTBOOT.
the command "fastboot devices" gives me a repeat of the same prompt with no error. (I can't get fastboot to work in normal debugging mode either, and I don't know if it usually will, because this is the first time I've used it.)
the command "adb devices" gives me response-- "list of devices attached" with nothing below (ADB works fine in debugging mode though).
I thought it might be a driver problem, but "Android bootloader Interface" driver is on the device manager list while phone is in fastboot, and seems to be properly
installed; I can't seem to find another suitable driver to update it to anyways.
Beyond that, there don't seem to be any other drivers running in the device manager either.
It's to the point where I'm considering taking the long way around and re-rooting through passimg, but that may not work anyways from what I've been reading, and that still won't fix my fastboot issue.
Any ideas on why I can't get fastboot to work?

my devise manager lists it as 'Android 1.0' when connected with fast boot..
if the drivers were installed on their own, then uninstal them.. and manually update the drivers (download them yourself)
that might help.. idk..
Sent from my nexus one

I think that may be part of the problem because I'm not seeing Android 1.0 on the device manager list. I do have an unknown device on there, but I can't update the driver with any of the Google USB drivers. Also, I'm pretty sure it's not my N1 because I'll unplug the N1, delete the unknown device, and scan for hardware changes and it will pop up again, so I don't think it has anything to do with my phone.

Put your phone in to fast boot, plug the phone in to a different port on your computer. If you have been plugging it in to the front, plug it in to the back. If you have been plugging it in to the back, plug it in to the front.
This should force windows to re-detect your device and it will hopefully install the missing drivers you're needing...

That was a good idea, but I had no luck with that one either. Thanks though.

Alright, shreyas said device is "Android 1.0" from windows device manager when the phone is in fastboot. Why does mine say "Android Bootloader Interface" and is this the case for everyone else?
Even more interestingly, I'll uninstall it, manually install whatever driver I chose for it, and that installation will fail. Then, I'll uninstall it again and have 'puter automatically scan for hardware, "android 1.0" pops up as one of the unknown devices but then gets reassigned as "android Bootloader Interface" after automatically installing drivers.
Oh yeah, I'm running Windows 7 64.
The drivers mentioned here didn't help either

i am on win7 32!
btw umm try this link
http://android.modaco.com/content/z...com/319156/winxp-7-zte-blade-drivers-and-adb/
another umm stupid thing mayb, did you try out adb wireless..?

Have you tried using the PDANet drivers? Those are the ones that I've had the best luck with on my Win7 x64 laptop.
EDIT: Seems you have...
I'd recommed using an application called USBDeView (I think?) to manually uninstall all USB drivers for Android/HTC/ADB/NexusOne/etc, and THEN installing the PDANet drivers.

Thanks for your help. I ended up downloading "superboot," which has fastboot on it, and it works just fine. I don't know what the deal is with the fastboot that came with the SDK but my computer just doesn't seem to like it. I checked and rechecked all commands and file directories, and I just don't get it...oh well, I hope this helps others.
Thanks again.

[Q] ADB doesnt recognize HTC One in Recovery

I have a nandroid backup.
Its too big to keep on the phone at all times
Therefore its been placed on my computer
And in the case i need it (boot-loop), how can i transfer the backup while in CWM?
ADB seems to be the simplest way, but adb cannot find my device when it is in the bootloader or in custom recovery.
Am i missing something? Or is there another way to solve this issue.
If anyone could help, id be very grateful.

Hi
Greetings,
When you boot in fastboot and connect your phone to pc does it shows fastboot usb if yes then it is recognised if no then you will have to download the drivers if HTC and install them

yes fastboot usb is shown and all fastboot commands work, its just that adb doesnt work when its in bootloader or recovery.
I did some more digging around and found that when the phone is connected while in recovery, the computer recognizes it as a "HTC MTP device"..and thats it. I cant upgrade the drivers of the said device or essentially do anything with it.
What am i missing?

ADB should only work under Recovery. I found that with the last HTC driver it didn't install for when you are under Bootloader, Recovery, or Fastboot. I forgot what version actually worked the best but it might have been the 3 series drivers. Anyway while under Recovery you'll have to force the HTC drivers to install thru your Device Manager. It will not automagically detect them. I would start with these drivers and try them out.
HTCDriver_4.2.0.001.exe
Universal_Naked_Driver_0.72.zip
HTCDriver3.0.0.007.exe

Thanks for the reply, ive tried the first two drivers, work fine when the phone is booted, but no avail in recovery. The laptop shows the device connected as "My HTC" while in recovery, but im unable to use adb commands as adb doesnt connect to it. Ill try the third 3 series driver and post an update in a few.
UPDATE: wont install, im running windows 8 and it says this driver is not compatible with this operating system.

Does it say its offline? What do you actually see when using adb. As for the driver in Windows 8, you have to disable driver signature checking to use them. There is a thread in the Nexus 4 forum on how to do this, which is here:

installed the 3 series driver, still the same problem. Heres some photos (which i should have attached originally) of whats happening.
The pictures are while the phone is normally booted, and then when the phone is in recovery.
Edit: Uninstalled all of the HTC drivers and devices inside the device manager, and only installed the Universal Naked Driver, the phone now shows up with a different name in device manager, but STILL does not work while in recovery.
Another pictures attached of how device manager looks with just the Universal Driver while in recovery.

anyone?

i have the same problem as u.. I tried both my missus Windowss PC now.. It used to detect it before. Now it suddenly doesn´t anymore. On my mac, same deal. Nothing detected.
Been googling around and i have found threads but they all end unsolved. ADB returns ADB devices blank. Kill-server or adb remount does nothing. in Fastboot USB its totally a ghost.
found any fixes?

I'm clueless too. I can only think to try other recoveries. Philz CWM comes to mind. I also uploaded the latest google usb drivers for you incase you want to try that out too. Google v7 USB drivers I think they are called. You'll probably have to force install them since they won't detect. Included the adb and fastboot from the SDK too. Last thing I can probably suggest is to try different USB port. Oh and TWRP too since it has the terminal built in it you could try starting up ADB from there.

Me too...
Did anyone ever resolve this? I'm facing it now, having tried multiple recoveries. Previously was able to use adb fine. (I'm on a mac.)

In case this helps someone else: The reason I lost adb was that I'd installed the drivers on my mac for EasyTether. There's a note about this on the EasyTether FAQ page. When I disabled the EasyTether driver, I was able to use adb again.

have you tied all-in-one-tool-kit ???

Not sure if this will help, but I had an issue like this with my asus tab - adb worked fine in android os but not in twrp recovery, device manager showing it as other device.
While in recovery with device connected to pc I followed this how-to from the device manager part on and got adb working in recovery.

HTC One(M7) not recognized by adb
Condition:
HTC One(M7) - rooted; s-ON; GPE ROM 4.3.1
Recovery - CWM
I have a similar problem with my HTC One(M7). I'm working mainly on a mac (OSX Maverick), but I have also tried using a PC (Windows 8). I accidentally wiped the data on the phone while in recovery, and now I have a phone that only boots to the bootloader and recovery. Since backups usually take a lot of memory, I kept all of mine on my computer. The simple fix I've been trying to do is sideload the ROM to the phone through adb, however adb does not find the device. I repeatedly get the "device not found". However the device is recognized in fastboot, and i always get the "fastboot USB" when it is connected. So I am unable to flash the ROM I need to the phone because it is unable to communicate with either computer. On the PC I made sure to have had the proper drivers, I downloaded HTC SYNC, and have tried updating them manually. However I always get the "error Code 43". The PC also does not recognize the device, so again I am unable to communicate with the device. Can I plz get any help, I have tried reading multiple forums, but have had no luck trying any solution. I would really appreciate any advise; Im desperate to fix the phone.

Take a look at this FAQ post and see if this doesn't help solve your problems. I would also recommend updating your CWM recovery to the latest.

having a similar problem. My system and everything is wiped all I have is TWRP 2.6.0.1 and I'm trying to end with cyanogenmod. theres no sdcard slot so my only option is an adb push through recovery. Adb doesnt recognize it, it just doesn't return anything in the list of devices when i type adb devices. in devmgmt it lists my phone as a disk drive... I have tried to update the drivers to the universal naked ones, but then windows says that it already found and installed the best driver software I have the T-Mobile variant but I thought I'd post here since this problem is more than likely not carrier specific and I didn't wanna add another thread. I can do fastboot just fine when in fastboot usb mode, but in recovery no adb... I can't install the naked drivers it just says that the file is incompatible

PC won't recognize HTC One after installing KitKat 4.4 Sinless ROM 5.1.1

Hey guys, flashed Sinless 5.1.1 last night and ever since installing this particular ROM I'm unable to access my phone's folders via MTP or anything. I've tried re-installing drivers on my PC, rebooting phone and PC several times, trying to access my phone in ADB and fastboot... I can't even push or sideload a new ROM so I really don't know what to do!
Anyone got any idea what to try next and/or how to solve this?

Did you enable Developers options USB debugging?
If not go to about phone and click on Build number a
bunch of times. If that doesn't work install latest HTC
drivers.

I'm actually running that exact ROM and my phone is seen on both my Mac and Windows 7.
Did you try a different USB port? Does a message pop up on your phone asking to trust your
computer? My computer wouldn't see my phone until I accepted that pop up.
If you've tried all that then give a little more info on your PC so we can diagnose it.

Kinda stumped then! Only thing I can think is that you don't have the very latest drivers.
Can you ADB and see the phone? Check the following thread on how to do this.
(Sorry if you already know how)
http://forum.xda-developers.com/showthread.php?t=2365506

If I do "adb devices", nothing shows up. Simple commands like "adb reboot" respond with "error: device not found".
I've just flashed ARHD 31.6 (Android 4.3) and re-installed drivers and my phone still isn't recognisable. I'm lost!

Okay, big trouble now!! I just read elsewhere that it could be an internal storage corruption problem, so without thinking I formatted internal storage along with data and system in recovery and attempted to ADB sideload a new ROM and was going to start over. Stupid idea! ADB still isn't working so now I can't even sideload or push a ROM. All I have to work with now is fastboot and recovery, and my PC isn't recognizing either of them. Any ideas?

YOU AREN'T GOING TO BELIEVE THIS!!!
Girlfriend stayed over the weekend and happened to swap our USB cables over. She left and took my OTG cable and left me with her identical looking USB charge only cable.

I know this thread is old but if someone stumbles upon it this is what I did.

This is what I did.
When you get to the phone into recovery mode unplug the USB plug and then plug it back in again. Windows should search for the driver. When windows finishes open device manager. Look for the nexus 6 with the yellow icon. Follow the steps attached in the picture. Credit for the driver steps goes to wugfresh, steps obtained from his toolkit.

I will try wugfish to install the drivers and then see if I can use ADB after that.... I definitely did not have the device show up as nexus 6 in device manager other than the mtp part... pretty hard for that not to show up..... I'll give it a shot on Sunday unless the ota drops to the phone first.

A simple unplug and replug in fixes the issue...when you get to the adb point on the phone and you make sure the driver is installed on the computer correctly, simply unplug from the computer, replug in and continue

Had the same problem on a Win7 machine that I have used for several phones. Would see the device in ADB when full booted, see it in fastboot, but when in ADB sideload, could not see it. Turns out it was trying to use the Samsung ADB vs. Google/N6 driver for ADB. Had to do a lot of hoop jumping, deleting/changing drivers, but worked great after.

Can you explain exactly what you did? This is exactly what my N6 is doing. When the phone is on, under "Device Manager" it says "Samsung Android Phone - Android Composite ADB Interface". When in Bootloader it says it is a a "Samsung Android Phone - Android Bootloader Interface" and I keep deleting the driver and trying to reinstall the default drivers from the SDK Manager but it just keeps loading as the damn Samsung.

I followed those instructions as well and it still registered as a Samsung Device. However, I did finally get it to work by going through my "Uninstall or change a program list" and removing a "Samsung Driver Installation" program I had installed for my wife's S4. Then I ran back through Wugfish's driver directions and sure enough, it finally registered as a standard Android device and not a damn Samsung.

I've tried on my Nexus 6, every time it goes to recovery mode it doesn't show up in device manager.
I've already unistalled all drivers, used the nexus root tool to reinstall the drivers, it doesn't matter. It works fine the first part when you need to use ADB to restart the device in bootloader mode, then you select recovery and nothing happens the device never shows up, so I can't install/uninstall any drivers because it simply doesn't display anywhere, wtf!

Did you try to disconnect and reconnect the USB while the phone was in recovery?
Sent from my Nexus 6 using XDA Premium HD app

I don't know if this will solve your issues. When I was side loading the 5.1 update I couldn't get tmy win 7 machine to see the device after rebooting from adb to sideload.
I ended up finding a thread somewhere that suggested a newer version of adb. Once I downloaded the most recent version it installed fine.
I also rebooted into fastboot through adb, went to device manager and found my nexus, manually updated the driver. After all that everything worked fine.
Don't know if that helps or not....

I can't get my computer to show my N6 as a phone. All it shows is Unknown Device. I've loaded the Google Drivers yet it doesn't list them when trying to load them manually.

I found the problem
each mode has a unique hardware ID
when phone is in normal mode with USB debug, when it is at bootloader and then afterwards when it is in recovery mode
the last mode, hardware ID VID_18D1&PID_D001 didn't get any dirvers installed, evne downloading official drivers from google and other parties.
I had to manually edit the android_winusb.inf file and add the hardware ID %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D001 under ;Google Nexus (generic)

I had to manually edit the android_winusb.inf file and add the hardware ID %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D001 under ;Google Nexus (generic)

My device needed %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D002.

This happened to me too, I just ended up using a different computer: https://plus.google.com/+LoganJonesJ/posts/hrDRAnyrotf

When you get to the phone into recovery mode unplug the USB plug and then plug it back in again. Windows should search for the driver. When windows finishes open device manager. Look for the nexus 6 with the yellow icon. Follow the steps attached in the picture. Credit for the driver steps goes to wugfresh, steps obtained from his toolkit.

A simple unplug and replug in fixes the issue...when you get to the adb point on the phone and you make sure the driver is installed on the computer correctly, simply unplug from the computer, replug in and continue

Thanks so much for this! I had tried EVERYTHING trying to get my 6P to connect with no success. This simple fix was exactly what I needed.

Fastboot "waiting for device"

I already enabled OEM Unlock and USB Debugging in Developer options.
then I connected my LG G4 H811 to PC and confirmed MTP.
adb devices just shows:
List of devices attached
If I select USB charge instead of MTP, the adb devices shows:
List of devices attached:
LGH811***** device
Then I can do "adb reboot bootloader"
Phone shuts down and get on fastboot with this "waiting for device" I got stuck there.
Does anyone know the reason? Really need to unlock bootloader and then root my phone.
Thanks

Yeah I'm experiencing this too as well! I just recently updated to 20p and I am trying to root again. I was able to use fastboot to install twrp before. Don't know why this is happening.

This is what I did
In fatsboot I saw in device manager my phone was "rats I don't remember-something bootloader device" I chose update driver and browse my filkes and chose the marshal one. after that everything worked fine. Sry I'm an anxious person. Hopes this helps and if not or I could help more ask me more and hopefully I'll be more mellow lol.

Bootloader unrecognized
I used the app shared above and used it to locate the driver and ended up having to roll back to a previous driver and it worked in my case.

Can one of you share a link to the driver you used?

I'm at work won't get off for another 13 hours but like the post maybe two above here it was Marshall something. Go to device manager look for the boot loader adb interface can't remember exactly what it's called and double click it and use the menu option to rollback not update the driver and you should be good. I tried everything else including the one touch and only the rollback worked.

For my computer, it shown up as something like "Kedacom USB Device" in the Device Manager, but I rolled back that driver from 11 to 9 and it worked beautifully!

Do you have the driver? I have none to roll back to.

Okay...
Okay so yeah it says kedacom usb device, that gives me the waiting for device error...in device manager when im in fastboot mode find kedacom device and click on it to see android bootloader interface. Right click on the android bootloader interface and choose update driver, browse my computer for driver software, then let me pick from a list of device drivers on my computer. From there I choose marshal London bootloader interface. From there everything works... don't have to restart computer of phone, everything works together perfect. Either it came with my computer or its from this install of adb... the 15 sec adb installer http://forum.xda-developers.com/showthread.php?t=2588979. Try my steps see if it works!

I am having the "waiting for device" issue. But I dont have the "Marshal London" drivers. I have adb 15 sec drivers installed. Any idea where I could get them?

okay another try..
Okay have you tried, while the waiting for device prompt is up, instead of telling your computer you want to select from the list of drivers, to choose automatic: search online for the driver?
