Thank you for everyone who posted on the subject of [Q] ADB doesn't detect device while in bootloader.
I am seeing the same problem.
I have an HTC Rezound that I would like to root.
USB Debugging is on Phone
Turn ON the USB debugging option on your device by heading to Menu > Settings > Developer options > USB debugging
USB connection type is "Charge Only".
Menu->Settings->Connect to PC
Set the default connection type to 'Charge only'
Device is plugged into a USB 2.0
I went to
http://www.htcdev.com/bootloader/unlock-instructions
Before beginning the instructions it said to make sure that I had the updated versions of Google SDK, Java and HTC.
NOTE: I am not using the LATEST java. I did not update my java because the software I use for my job is a bit behind. I am using Version 7 update 60 (build 1.7.0_60b19)
I used these links to get the "latest" versions and installed them as directed.
Google Android SDK zip:
http://developer.android.com/sdk/index.html
Java Runtime Environment:
http://java.com
HTC Sync Manager:
http://www.htc.com/hsm
Instructions from HTCdev.com
Step 1
After powering down, press Volume Down and while pressing Volume Down, press Power holding both buttons to start the device into Bootloader mode. If you have difficulty, power up normally, go to Settings->Battery and deselect Fast boot. Power down and try again.
Step 2
Use the Volume buttons to select up or down. Highlight Fastboot and press the Power button.
Step 3
Connect the device to the computer via a usb cable
Step 4
Download the following fastboot binary for your OS using the following links:
Platform Download Size (bytes) Checksum
Fastboot binary, Windows
(Unzip the file before executing) fastboot-win 83753 a90c25141e306b3062dc8e47e14a1005
Step 5
Open a command Prompt: Windows: Start->"cmd"
Type in Command Prompt: fastboot oem get_identifier_token.
It says it is waiting for a device message.
And this is where I get stuck.
I rebooted the phone.
<SDK location>\android-sdk\platform-tools\adb devices
I ran adb devices and it sees the device and gives me a device number.
<SDK location>\android-sdk\platform-tools\adb reboot bootloader
This put the phone in bootloader mode.
<SDK location>\android-sdk\platform-tools\adb devices
Now I no longer see the device.
Now you say, I don't have the right USB driver. Sounds perfectly reasonable.
I tried several different drivers (the ones from the brand new HTC sync I thought would work, but they didn't)
tried the drivers that came with the
WinDroid Universal Toolkit by WindyCityRockr
http://forum.xda-developers.com/showthread.php?t=2437371
and most recently I tried the Universal Nake Driver created by 1wayjonny.
http://forum.xda-developers.com/goo...nt/adb-fb-apx-driver-universal-naked-t2513339
Same problem.
So clearly, there is something else I am not doing.
I would really appreciate your help.
When your phone is in fastboot mode you cannot use "ADB Devices" to view it, you can to use "fastboot devices" instead. It will either find or not find the device. If it does not, I think it is still a driver issue.
I'd uninstall all your fastboot drivers (HTC etc), plug in the phone again, wait until it asks for driver, then have it search automatically online (assuming you're on W7). Then try fastboot again.

Downloaded and installed ADB. Following tutorial here:
https://www.xda-developers.com/nexus-6p-bootloop-fix/
Specifically:
- Connect your smartphone or tablet to your computer with a USB cable. Change the USB mode to “file transfer (MTP)” mode. Some OEMs may or may not require this, but it’s best to just leave it in this mode for general compatibility.
- In the Command Prompt window, enter the following command to launch the ADB daemon: adb devices
- On your phone’s screen, you should see a prompt to allow or deny USB Debugging access. Naturally, you will want to grant USB Debugging access when prompted (and tap the always allow check box if you never want to see that prompt again).install adb
- Finally, re-enter the command from step #6. If everything was successful, you should now see your device’s serial number in the command prompt. Yay! You can now run any ADB command on your device! Now go forth and start modding your phone by following our extensive list of tutorials!
https://www.xda-developers.com/install-adb-windows-macos-linux/
I did all the above. But don't see anything from:
C:\ADB>fastboot devices
C:\ADB>fastboot flash boot 6p48C.img
< waiting for any device >
Nexus 6P was plugged into the USB cable on Win10 machine. Am in MTP mode. Most recent Google USB drivers installed.
I have done OEM Unlock in setup|Developer options. I have also turned on USB debugging in same options.
I am [obviously] lost. Anyone know what else I might try?
OK, I have made a little progress messing around on my own. It seems that running from the CMD line in Win 10, ADB command works but Fastboot does not. WHY? Bith are in the same directory.
If I type Fastboot by itself, then I get a list of the associated parameters, which means that the CMD system DOES recognize the Fastboot command.
Now, if I run CMD====> "ADB devices", it looks like my device is recognized and attached (that is my serial# below).
But if I try CMD=====> "Fastboot devices", as the instructions require, I get nothing. And if I try to run the flash job via Fastboot, that does not work either.
==================
C:\ADB>adb devices
List of devices attached

Wondering if I need to install the Android SDK on Windows for this process to work?
I Think You need to Redo The process from Step One.
I Heard about This and Never Did An OTA.
If it Persists Try Using A Different PC and If After That It doesn't work Then Yes Android SDK is The last Option.

Solved. I needed to add the ADB install directory to the environmental path. Don't quite understand why, but doing so allowed me to get the problem fixed.
So my device is recognized when it's turned on but then I go to command prompt and click ADB reboot bootloader (enter). It just says waiting for device. If it's on and I click ADB devices in the command prompt it tells me the serial number and then says device. On the computer management it is recognized as a device it says the name Xperia XA Ultra. I tried to update the Google driver into ADB but that was a failed attempt. I couldn't quite understand what I was supposed to do there or really even follow the instructions because it kept telling me that I was unable to update drivers after I followed the instructions they gave me. I just kept getting an error message. So I'm wondering how do I solve this problem? I really would like to unlock my bootloader and I'm not even sure if it's going into fastboot. I got the notification after turning off the phone hold Volume Plus and plug it in it said of my computer that it was installing the fastboot drivers. I'm assuming it was in fastboot at that time even though I didn't get a blue light it just turned blue for a minute and then it was Green. It said it was installing fastboot drivers so I'm assuming it was in fastboot mode. This is a really tricky process I guess.
What windows do you have?
Also I would recommend you to Google how install fastboot on your Windows type.

I have windows 10
Windows 10. Why would I need to install fastboot on Windows? Fastboot is on my Android device. I use ADB. Android debugging bridge is the bridge that goes between your operating system and fastboot the bootloader and Android and all of that in order to be able to communicate with the phone. Why would I need to install Fastboot on my windows? You sound like a customer service representative. I can't even talk to them anymore because they tried to get me to act like Chris Farley.
If you don't install fastboot on your computer you can't unlock bootloader you can't install custom recovery or root the phone!

Hello,
Here is the link to the ADB Installer that contains all the files you need (ADB, Fastboot and Drivers). Download and following the screen information to install the program.

Hi there
please note that Windows 10 x64 blocks the installation of unsigned drivers. To be able to install them anyway you have to enter the Windows Test Mode. To do this you just have to run "bcdedit /set testsigning on" in an administrative command line and restart your computer afterwards. You'll see "Test Mode" at the bottom right corner of your desktop. To leave the testmode use "bcdedit /set testsigning off" and restart again.
Done all of this and it doesn't work...
You have to use drivers from Sony for Flashmode and use drivers included in Flashtool (C:\flashtool\drivers) for fastboot and ADB. No problem for me with Windows 10 64bits and don't need to use Test mode.
Dear Firmware Gurus,
I received a gift from someone, the Huawei Mediapad 10 Link, and the Android version 4.1 + old firmware was making the tablet very slow. So I decided to:
1. Root device with framaroot --> Success.
2. Find and download newer official ROM for the table --> Success.
3. Install Rashr + install TWRP recovery through it --> FAIL And this is the moment I really regret. I didn't imagine that this application will give me boot loop forever.
Anyway, now I have bootloop and I can only access Fastboot by pressing Volume+ & Power Button. But when I connect the tablet on Windows OR linux, while on Fastboot screen, the adb + fastboot does not see any listed devices. Please help me with all kinds of instructions how I can see the device listed in adb and reset or upgrade the firmware from there. I am hopeless, and sad, and willing to donate with PayPal as appreciation if you can help me.
Hi , all you have here just follow carefully

Thank you a lot. I have solved the problem and upgraded the firmware at the same time following the instructions in the link you provided but I also needed to do some things not in that link (because adb shell doesn't work I had to upgrade firmware through fastboot only).
This tutorial is made for all those who used the SHIIIII**** application called Rashrr that soft-bricks thousands of phones every day trying to install TWRP recovery. I've seen many people complaining about this but finally there is a way out for this device at least.
So here is the conclusion for everyone else in trouble:
1. Go to this link and follow instructions until you can install Google SDK studio + Google USB Drivers.
http://www.teamandroid.com/2012/07/30/how-to-set-up-adb-fastboot-with-android-sdk/
2. Connect your device to the charger, click Power button + Vol+ to Enter into fastboot mode as in this link.
3. Connect the USB cable to your Windows computer and then go to Device Manager, you will most probably find your device as Unknown Device. Click on it and Update Driver. Pick this driver from a a list: Android Composite ADB Interface..
4. Then go to the SDK Platform Tools folder where the adb and fastboot commands are:
C:\Users\<Your_User_Account_Name>\AppData\Local\Android\sdk\platform-tools
Copy all the contents of this file inside it.
This archive includes the most updated firmware images of Huawei Mediapad 10 Link s10-wa (WiFi Only Version).
5. Run the cmd as Administrator and go to the same path where you put the files run the command "fastboot devices" and something like this should appear to indicate your device is being properly connected:
?????? fastboot
or
0x12d1 fastboot
If this line appeared it means that your device is being seen by fastboot and it will comply to your commands.
6. Run upgrade.bat while the device is connected in fastboot mode. Do not interrupt while your system is being upgraded.
7. Reboot device and enjoy! Don't forget that first boot takes some time seeing Huawei logo. Give it time!
My Huawei Mediapad 10 link+ start black screen after reboot..thi happens after I flashing the device why???
Did not worked for me

you have the files bro?
I have literally tried everything. Sony's website does NOT have driver for the XA2!!! What gives?
I'm trying to unlock the bootloader through flashtool but I keep getting this message "Device connected in flash mode but driver is too old".
I also tried the 15 Seconds ADB Installer thing, no luck.
I also tried following Sony's guide but get stuck at the bold part:
Turn off your device.
Connect a USB-cable to your computer.
On your device, press the Fastboot key (Volume up for most devices, see Useful key combinations) at the same time as you connect the other end of the USB-cable.
Windows users: When asked for a driver, open the Devices and Printers directory, click on the fastboot driver and press Update. Browse and point towards the location of the new android_winbus.inf file.
When your device is connected, open a command window on your computer and go to the platform-tools folder within the Android SDK folder.
Enter the following command:
fastboot devices
Verify that you get an answer back without any errors.
I don't have the option to open a CMD, but only powershell, and powershell doesn't let me run the "fastboot devices" command properly. Keeps trying to open an application.
What else can I do? I found some driver online and tried to install it through "legacy" mode in device manager but I keep getting some kind of error.
Can someone please help me out? I really want to root this thing
Thanks!
Anyone?
Wow! I came here looking for an answer to the same question and nothing but crickets? Sony does not list a driver for this device and I find it odd. Does it use the XA driver? You would think they would be listed together if it did. Nobody has an answer on this?
I found out you use the XZ2 driver. Worked for me.
Y cant i get fastboot drivers to read in Windows 10. I have updated the software to the latest update. Developer options are turned on. USB configuration is set to file transfer. In a regular state Windows 10 readds the phone and I can access the contents of the phone. I opened a power shell (regular and as admin) I typed "adb devices" it reads. (I have enabled advanced reboot.) I use the command "adb reboot-bootloader" in boots to fastboot. Now it loses connection. I Open the Run dialog box by pressing Windows Key+R. Type “devmgmt.msc” besides Android is a yellow triangle, then click Update Driver.A new window will pop up. Select the ‘Browse my computer for driver software’ option. I copied the drivers from the OnePlus 5 folder. Try to install but nothing. This is where in stuck. Please help. Thanks
