I can not do riconoscCiao all, I state that I'm crazy, I almost flash a boot.img in the cell only if the fastboot boot and connect to the PC despite having correctly installed the drivers when I start to see the string adb devices connected I said that does not find the device and do not know what to do to show him, if I close the process from taksmanager adb then try again is the typical written that the cell is connected to port xxxx but soon after I said that there are no devices connected. Please help me because I do not know which way to turn

I am using fastboot with the "Google USB Driver package, revision 4" from the Android SDK. The device is detected just fine when I am booted into fastboot but nothing is ever listed when I run "fastboot devices" from the command line.
I have tried this with my "Android Dev Phone 1" (I got it from ebay!) and my unlocked/rooted Droid Incredible. Both devices do have USB debugging enabled. Adb works just fine when the devices is booted up.
With the dev phone when I boot holding back/off I get the message "serial0". When I connect it to the computer it changes to "fastboot", as expected.
Any suggestions?
Anyone?
waiting device
I have similar problem here. Fastboot cant seem to detect any device plugged to usb. Tried installing all drivers from LG setup, got sdk and ran cmd promt, cd directory, then typed fastboot erase recovery. It just waits for the device. Is there anyone familiar with this prblem. Hope someone can help. THanks!
I'm wondering if anyone has run into this problem before?
I'm trying to unlock the bootloader on my friend's Photon Q, I downloaded the SDK and installed the Motorola drivers. But when I put his phone into Fastboot mode, the "fastboot oem get_unlock_data" command does not work and CMD just says waiting for devices.
Yes I'm shift+right clicking on the platform-tools folder in the SDK to run the Command Prompt and I did download the correct Fastboot file. The command "adb devices" shows nothing when his phone is plugged in, but it shows my own phone (A Motorola Droid Bionic) when it's plugged into the USB cable. RSD Lite also recognizes both phones when powered on or in Fastboot mode.
I have no idea what to do at this point, we just need to get that unlock data to plug into the Moto site. Would it be possible to use someone else's unlock key or is each one randomized individually for the device? Or would that even work because my computer can't do the command for the unlock data, so maybe it couldn't push the unlock key onto the phone?
quick thought: did you enable usb debugging on the device?
edit: i guess that wouldn't make any difference in fastboot mode...
anyway, yeah, i'm pretty sure each device has it's own unique code. it's odd that fastboot recognizes the device, but the command isn't working. i bet you will get it somehow tho. a similar thing actually does happen to me sometimes, and in my case, it is because my usb ports are going bad and the computer loses connection with the phone.
Man nobody has anything eh? That's a crying shame. I tried using a different computer and went through the same course and still nothing.
I did try USB debugging on and off on both machines, didn't change a thing.
In order for the drivers (and therefore adb) to pick up the phone, I needed usb debugging *and* the phone not to be in charge only mode. Maybe that will help?
If not, when you reboot to fastboot and connect the cable, look at the devices installing list (if win 7) or device manager, and confirm the pc sees the fastboot device. If not you may need to reinstall the driver. Strange I know, but I needed to after getting my unlock data, holding off on unlocking due to the warranty voiding note, then trying again a couple days later where it wouldn't recognize. Seems to be finicky drivers to match a finicky device. But I do love this keyboard lol...

We've only ever tried it in MTP mode and USB debugging enabled. This is day three of plugging it in and pulling it out and still no go. This is a royal pain, that is for sure.
Download Motorola Device Manager from the website, install, plug in phone. Place the phone into mass storage mode WITHOUT debugging enabled, then other modes, then back into bootloader mode then into fastboot mode. This will install EVERY driver, I didn't see that as one of the things tried.
Once you are in those modes, Android ADB device driver will install.
Hope that helps...

So I turned on USB debugging and made sure the RSA key fingerprint was remembered on my phone. I connected my phone to my PC with the HTC drivers installed and ran "adb devices" to make sure that my PC and phone are communicating with each other, and the device is online. I do "adb reboot", and the phone reboots, but then my phone appears offline to my PC. I've looked around for an hour and cannot seem to find the root of this issue...
I've found toggling USB debugging will make the PC recognize the device again, but then I have issues when it comes to try to S-Off the device. I think this is the main cause of the problem.
It appears when weaksauce re-roots after boot, adb no longer recognizes my device. Any fixes?
Dear all,
Please Help me. My One plus one is on CM12 official rom (rooted). Problem is when I connect my phone to computer and use ADB it is detected (adb devices: number & devices detected) but when in fastboot (fastboot devices : nothing is detected) I check in my device manager (yellow triangle on android ) My problem is why CAN it be detected when my phone is on but NOT during fastboot.
Necessary checks done : USB debugging, Universal driver, SDK installed, USB driver reinstalled again, tried changing usb ports on computer, tried on 2 laptops)
I am helpless, tried checking on forums can not find the answer.

Tried adb reboot bootloader then phone boots into fastboot mode but from here..
is total no connection. Tried checking fastboot devices (nothing), fastboot reboot (waiting)
then i tried as u said unplug & plug in (not recognize) from here adb cannot be written anymore. (no more commands can be typed). Tried others like down loading Pdanet ,force install driver..Nothing works. Thinking ,did I corupt the bootloader while I was rooting it last time.?
I think if something was wrong with bootloader you could not either boot .
Do you use antivirus to pc?
Try without antivirus
What happening the false is from computer
Mine is reverse issue. When in fastboot mode, pc recognizes OPO, but when OPO is normally connected to pc, adb is not working. Its charging and can transfer data through USB, but OPO is not recognized through adb commands. Device Manager too recognizes my OPO only when it is in fastboot mode and not when normally connected via USB for data transfer.
I have a software, through which I can REVERSE TETHER my PC's internet to my mobile via USB. Because my OPO is not recognized via USB in normal mode, I can't do that. Any idea, what's wrong with my OPO.
(I have installed Android SDK and google usb drivers, for my OPO to work in fastboot. I have rooted. My pc runs on win7)

Hey guys,
I am Currently attempting to unlock the bootloader on my Pixel 6a, but when I attempt to connect via fastboot in the bootloader my PC shows nothing connected? I can push commands through ADB while the device is booted and have full functionality, but as soon as I reboot the device into the bootloader I lose connection to my PC. OEM Unlocking is enabled in the settings and I have toyed with updating it to the latest update and factory resetting the device. It shows correctly in device manager as 'Pixel 6a' while USB Debugging is disabled and as 'android composite ADB interface' while it is enabled.
To clarify as I am sure many have seen this issue before I do not believe it do be a driver issue as the device will not show up at all in device manager, not even showing with the incorrect driver (No ding to indicate a device has been connected). I have tried using 2 different USB C -> A cables in all slots of two entirely seperate PC's (Both running Windows 10). When I enter fastboot with OEM Unlocking disabled it acts no different to when it is enabled.
I appreciate any help or insight any of you folks can give me.
Device is currently running Android 13 Build number TQ2A.230505.002 if you need anymore info please let me know.
The OEM Unlocking toggle does not affect whether USB function works. It is only a "safety" that allows unlocking the bootloader.
Have you ensured you've installed the correct drivers? Google USB Drivers
I have spent a long time looking at drivers, but I have no device to install the drivers to as the connection drops out once I eneter the bootloader. I have used Zadig in the past to install the correct drivers for devices but when I reconnect the device while I have it open it cannot even detect a new device being connected to the PC. (Also no audible tone which would be heard even with incorrect drivers) I actually only recently used Zadig to install the correct WinUSB drivers for my S10e in which I connected it to my PC in download mode (Queue audible ding) and used Zadig to overwrite the incorrect driver with the correct one. It's almost as if the device will not communicate while it is in Bootloader mode?
I assume you have checked with the 'fastboot devices' command to see if your device is connected when in fastboot mode?
