Windows 7...
Seems I can have either ADB drivers installed for when the phone is booted or when the phone is in fastboot mode, but not both. I have fastboot ADB drivers installed now as I need them the most; it's easy to reboot the phone into bootloader. Am I stuck with one or the other? If I install the ADB driver when the phone is booted I lose the fastboot drivers. TIA.
I don't think you lose the drivers... you just can't see the device using ADB when in fastboot mode and vice versa.

It's more like I have to install from a different driver package for booted vs fastboot condition. Both work, I just have to redo the driver install depending on the state of the phone. Seems odd.
Hey, I've been having a lot of trouble getting fastboot to work properly. I can get adb commands to work with my phone on but fastboot commands in fastboot mode don't work at all. I've been at this for about an hour.
I sort of get what you mean when you're saying you need to install separate drivers each time you want to switch between having adb and fastboot work. How exactly did you install "fastboot" drivers and how would I go around doing that? Help would really be appreciated!

So I am having a lot of problems with trying to root my nexus 7. I'm pretty sure it boils down to a driver issue but I'm not sure. I have tried installing the correct drivers over and over again also uninstalling other hardware manufacturers drivers and I cannot get adb to recognize my device when it is shut off and in the boot loader.
When the tablet is on and I have debugging on, adb shows up and is recognized, however my problem is that whenever I reboot into the boot loader I lose adb recognition. So therefore I can't root or do anything else. Fast boot commands work fine its only the issue with adb.
If anyone has any suggestions as to what I can do I would really appreciate it. I don't know if its just a hardware issue or something I am doing wrong on my end.
This is also not my first time manually unlocking/rooting a device
When you initially connect, the device shows up as a "Nexus 7".
When you reboot into the boot loader, the device name changes, and there is no driver for that device.
As far as I could tell, I would have to do the root process under Linux to avoid this issue.
As for me, I just ignored the issue. By the time you reboot the bootloader, you are already rooted.
The only thing you do after the reboot is rename a file. For now I am missing that step...
Yeah I'm using windows xp. When its in boot loader it does change names. I can unlock the bootloader via fastboot but can't do anything with adb. Lol I don't know what else I can do, I'm at a loss.

Like I said - I think you are done...
Install a terminal on the Nexus and see what it says to "su". I use one called "terminal emulator". Works fine.
I think fastboot uses adb.
If you connect your Nexus, and type "adb devices" in a command window what does it say?
I believe it says devices attached or something like that. (Not at my computer) but doesn't give me a serial # like I think it should.
If you do not have USB Debugging checked, "adb devices" will just show the List of devices line.
If I set USB debugging on, "adb devices" also shows the Nexus serial number.
If you don't see that, I would double check the device driver you are using.
Under Device Manager, Android Phone, Android Composite ADB Interface it shows:
Driver: Google Inc.
Date: 5/24/2012
Version: 6.0.0.0
Digital Signer: google inc.
Well if I have USB debugging on and tablet on and do adb devices I get the serial # but once I go into boot loader and do adb devices I don't get the serial #.
For device manager I can choose adb interface or adb original interface. I'll have more info when I get out of work and at my computer. Do you have a link to the drivers you used? Or where to find them. Because I have tried a couple of different drivers posted around to no avail.
BTW thanks for helping me out.
I would not use any posted driver - you don't know where that thing has been.
Download the SDK from Google; the correct driver is in there.
Just point the device manager to it when you install drivers.
There are a lot of good descriptions on installing drivers in the other nexus forums
But - again - I think your device driver is fine. You will not be able to talk to the Nexus from ADB after you boot the bootloader
Bootloader has a different device name which ADB can't use under Windows.
Use Linux if you want to do that.
ok, so pretty much what happens is when my tablet is powered on with usb debugging everything is fine and ADB is recognized. Now my problem seems to be when i reboot into the bootloader it seems as though the drivers dont stick and it asks me to install the drivers again and this is where i have had all of my issues. When i type in adb devices in, it just tells me "list of devices attached" and wont let me do anything else (fastboot works). Like i said i was able to unlock my bootloader but i cant flash recovery or do anything else.
When i go into device manage to select the drivers it gives me the option of choosing between adb interface, adb bootloader interface, adb orignal interface and nexus 7 bootloader interface. I have tried all options and nothing seems to work. I have tried multiple usb cords and ports.
If anyone else has any suggestions it would be much appreciated.
I didn't read through everything but your initial problem is adb doesn't work in the bootloader that's where you use fastboot commands either boot into a custom recovery or just boot up normal and make sure debugging is checked.
Try running fastboot devices and see if it shows up. What you need to do is have bootloader unlocked and dismiss the super user zip floating around here pot that on sd card download cwm recovery image floating around boot into bootloader then
fastboot devices
fastboot flash recovery name_of_file.img
fastboot reboot bootloader
select recovery from the menu
Flash the super user zip
Or download a rom that has root and put that on sd card instead of super user zip and after doing the steps above then selecting super user zip select the rom you downloaded and flash. If you're on Linux run sudo first.

TL;DR: Phone will only boot into download mode, however computer won't recognize my phone.
I installed all the drivers, have multiple versions of flash tool, even tried sideloading via ADB but device isn't recognized. How do I unbrick my phone?
Download and install the Minimal ADB and Fastboot tool v1.1.3...
http://forum.xda-developers.com/showthread.php?t=2317790
While in Download mode and w/ USB Debugging enabled, double click the Minimal ADB and Fastboot shortcut, then at the Minimal ADB and Fastboot> prompt type... adb devices
If your phone isn't recognized by ADB, then you don't have the correct drivers installed.
Trying to flash recovery partition.. as per many guides or http://forum.xda-developers.com/k3-...vo-k3-note-t3102997/post61860445#post61860445
adb sees the phone (adb devices)..
Reboots to fastboot..
But then fastboot devices reports nothing and fastboot flash recovery recovery.img just sits there <waiting for device>
Its like adb works.. but its not 'seeing' it in fastboot.
Phone is rooted.. I just need to get recovery partition changed to do backups and get a better ROM on there.
I faced the same problem and the solution was very simple. Make sure that you have downloaded the usb drivers corresponding to your PC's system type e.g., 32 bit or 64 bit. After downloading the correct version of the usb drivers make sure that you restart your PC. Hope this solves your problem.
Surely if I didnt have the right drivers already ADB wouldnt work ??
So am still getting exactly the same thing.. ADB works.. Fastboot doesnt..
Fastboot never seems to 'see' the device..
I have tried every set of USB drivers, lenovo drivers, minimal adb and fastboot drivers.. I can find..
What exact sets to making sure fastboot drivers are installed and correct ones.
Hi,
I just bought Mi A1.
Now, I wanted to install oreo.
So I was trying to root and install twrp.
Now I'm no expert, I just follow the provided steps and have been successful with past devices.
Note :
1) Developer enabled
2) oem unlocking enabled
3) usb debugging enabled
So I'm using this https://forum.xda-developers.com/mi...l-one-driversunlocktwrpfactory-t3695256/page2
But, there are two issues :
1) When I click on Reboot in fastboot/bootloader mode , it shows this in command prompt : http://prntscr.com/i2sn1o
and in the app, it automatically disconnects from the device http://prntscr.com/i2sncw
2) While this is happening and I leave my device, it automatically goes out from fastboot to power off charging mode.
I tried on another pc too, and followed the steps according to video, still no luck.
And I tried manual methods too, like https://www.youtube.com/watch?v=tRcYUMBgvaI
no luck there either.
Please help.
your adb driver is not installed correctly i guess, happened to me too.
try "adb devices" and will show no devices, if this happen, is the adb driver issue.
this fixed for me.

I don't know if there is issue with driver. Because during installation there was no error.
Also, when I command "adb devices" it shows me a device as number.
So it is able to connect to the device then right?
You must install adb drivers AND fastboot drivers separately. I always had to install them manually via device manager. If your phone reboots from fastboot mode automatically, I'm 99% sure that you do not have drivers installed correctly.

Hmmmmm. Ok, I'll do that then. Thanks buddy. I'll try again and reply back asap.!!
So i decided to root my A1. But fastboot isn't working for me.
Tried with previous adb files.
Adb works properly.
But when device is rebooted into fastboot mode. Fastboot isn't and to talk to it.
Updated adb and fastboot (sdk tools and even in AIO tool)
Just adb works.
Reboot to fastboot and my device is not detected.
Disabled driver signature enforcement in windows 10
OEM unlocking allowed.
Usb debugging on.
Tried multiple times.
Nothing seems to work.
Maybe driver problem but since adb works i don't think that's the problem and i have installed it again from AIO Toolkit.
Try different usb cable or usb 2.0 port
I had similar issue, fastboot was detected but haven't been able to do any command. So when the phone was powered on with selected usb to transfer files, in device manager the phone was listed as "Android phone - Android Composite ADB Interface", I updated the driver to "ADB Interface", rebooted in bootloader and was able to communicate through fastboot.

I would if i could get my hands on one. But i can't not for few more weeks.
Adb is working fine. File transfer is working fine. Charging is working fine.
So I don't think cable is at fault

Did u tested this? Reboot to fastboot mod and connect mobile to pc. then right click my computer then device manager. Then check for A1 port. Update /install driver Automatically from internet. May be it will help , may be not.
ADB drivers are different than fastboot. If you can detect with ADB and not fastboot, I would suspect you have a driver problem. Boot into fastboot, then check device manager for your device. It might not have any drivers installed and be an unrecognized device, or it could have incorrect drivers installed. My device needed fastboot drivers, I had the same problem as you.
Thanks all of you. Fastboot driver was the issue.

Follow the step. Windows will download correct driver automatically
