I've read a lot of articles about this problem but I can't resolve it. I decided to install my developer application on phone using wifi. To do this I need to do some things with my phone. The first step is to unlock bootloader. I stack on step 8, fastboot oem get_identifier_token shows info < waiting to device >. adb sees my device but fastboot can't. An idea?

My phone is HTC Wildfire S and these are steps which I am following:

  1. I restarted phone and entered into FASTBOOT USB mode
  2. I tried to run fastboot oem get_identifier_token command but without success.

I use Windows 7 Professional and my phone is recognized as HT1CSTR05155.

What is the phone model, and what instructions are you following? Did you reboot the phone in fastboot mode (e.g., by using adb reboot bootloader)? What OS you are using on the computer, and how does it recognize the phone at that time? – Sergey Vlasov May 26 '13 at 18:40
    
Sergey, see my edit. – pepuch May 26 '13 at 18:57
    
Did you update the bootloader? You should see ***LOCKED*** on the phone screen after you boot into the bootloader, otherwise you do not have the proper bootloader version for unlocking. Also check that the phone appears in the Device Manager without any question marks when you invoke fastboot oem get_identifier_token — seeing the question mark there means that the fastboot driver is not installed properly. – Sergey Vlasov May 26 '13 at 19:37

Linux/OSX

Run fastboot as root or with sudo.

Other OS: credits

if sudo fastboot oem unlock isn't working, login as root with sudo -s, then run fastboot oem unlock. – gihanchanuka Jan 13 at 6:10

Are you rebooting the device into the bootloader and entering fastboot USB on the bootloader menu?

Try:

adb reboot bootloader

Then, look for on-screen instructions to enter fastboot mode.

My fastboot was not detecting device but adm was working fine and your answer led me to what I was missing. – Raymon Jun 8 at 12:07

Problem solved. At the end I saw that drivers for android were not installed. I installed drivers from this site http://forum.xda-developers.com/showthread.php?t=2126036 and device is visible by fastboot. One thing I don't understand is why adb saw device and fastboot not.

This is because the phone presents different device identifiers to the computer in these modes, and different drivers are needed, so it is possible to have proper drivers installed for one mode, but not the other. The fastboot program is simple and will just show the < waiting for device > message forever if drivers are missing. However, the same message may appear if the drivers are installed correctly, but the phone is not in the proper state with fastboot device IDs. – Sergey Vlasov May 26 '13 at 19:59

ADB and fastboot require different USB drivers.

Whilst you may see your device under adb when your phone is on it will not be detected by fastboot until you install the driver for it and hence will show "waiting for device".

You can follow the steps below to do so:

  1. Open your device manager and reboot your device into fast boot by pressing volume up, down and power button simultaneously
  2. You will notice that device manager refreshes and now your phone has a yellow icon
  3. Download the Google USB driver, it is a zip file so go ahead and unzip it in your local directory
  4. Right click on the yellow triangle for your device and update driver, select the option update from local storage and select the folder "usb_driver" under extracted files in previous step
  5. You are good to go now, fastboot oem unlock will detect the device now

I had the same problem described by 'pepuch' on my HTC Desire S. I tried different drivers on relatively new computers running Windows 8 and Windows 10. In the end I found a link suggesting that I should try the (same) procedure on an older (desktop) computer which I did and the computer managed to detect my Desire S in fastboot USB mode and I managed to read the ID token. The link which steered me to the solution follows: http://forums.androidcentral.com/htc-one-rooting-roms-hacks/345350-htc-one-pc-doesn-t-recognize-bootloader.html

The only thing I did before starting in fastboot USB was to install the HTC drivers for the phone on the Windows 7 box and verify that the phone is detected when Android is up and running.

try reinstalling fastboot driver

while in fastboot

  1. open device manager
  2. expand android
  3. there should be one device
  4. right click
  5. uninstall
  6. uncheck "delete driver software"
  7. click on pc with magnifying glass (in toolbar)
  8. if not fixed, repeat, but check delete driver (you may need to download it)

I didn't realize it right away, but there are different ADB drivers and Fastboot drivers. I had installed the google usb drivers with the SDK extras and ADB worked great but I got the "waiting for device" trying to flash in fastboot mode.

I went to device manager from the control panel and saw the "Android 1.0" device with the yellow icon showing it wasn't working right. I had to update the driver and pick from the list of existing drivers which had a fastboot entry.

If no drivers work on Windows 10 or 8.1/8 and your goal is to just use fastboot to flash boot.img (Probably because you have S-ON), there's the way of the Linux: Get a USB stick ready and use Live Linux Creator and install a Live Linux like Ubuntu or Lubuntu onto the stick. Boot to the Live version (maybe you can use VirtualBox VM on Windows, not sure). Open Terminal with Ctrl+Alt+T. Type (without comments with // ofc):

sudo apt-get update //updates apt get
sudo apt-get install android-tools-fastboot //installs fastboot
sudo apt-get install android-tools-adb //optionally get adb
sudo fastboot devices // should show the device, don't forget the sudo!!
sudo fastboot flash boot ~/pathto/boot.img //sudo is doing the trick here, which is missing on Windows !!!
