"waiting for device" in Fastboot Mode...

[akinkoff85]

I had my phone rooted with the first official Android 11... I uninstalled root and completely reset the phone. Now I am on the second release of Android 11 and when I try to flash modified boot image in fastboot mode it says "Waiting for device" any suggestions or fixes? My device is available in adb mode doing the adb devices command... Please advise.

Did you unlock the bootloader again? Or was it just a wipe

Is usb debugging turned on?

Perhaps revoke it and cycle it then test ADB again.

If so run ADB kill-server

Then run ADB reboot bootloader should work then.

Also did you get the prompt when you did ADB devices on your phone to allow connections to that device?

Seems like driver issue.

Hey I'm having the same issue. Did you get this resolved?

It’s 100% a driver issue

 

[dladz]

If you're using Windows 7 there's a known issue with drivers, use Windows 10

I tried for hours to unlock on windows 10. I could access the device in adb while the phone was on and as soon booted into fastboot, Windows 10 says there was no driver.

Disabled verified drivers in Win 10 and was able to install the drivers, but fastboot still couldn't recognize the oneplus.

Quite strange that.

From a completely fresh win 10 installation I just plugged in my phone, install the OnePlus drivers, then activated USB debugging, allowed all drivers to be installed.

Added necessary ADB and fastboot files in a folder to C: and then typed ADB devices via powershell in that folder, got prompted to accept the device.

From that point fastboot worked and always has.

Hi everybody.
I have same problem.
(The story):
Unfortunately default Lenovo TAB M8 8505x OS have multiuser and many unwanted def app. So I was not success to limit my girl's tablet. Then I tried on custom rom and used fastboot mode ( by keep DOWN+POWER keys ). after this command (fastboot reboot fastboot)my fastboot mode was disabled and I can not connect to my tablet . now this show the logo for a few seconds and then restart again. I searched on the web to how to enable fastboot mode again and not found anything. One person prefer to wait for recharge battery completely and then charge but it does not work. to So I need help immediately.
This is my list of commands I used :

As you can see , fastboot reboot fastboot was the last command I used and then my tablet restarted and fastboot mode disabled for ever. So turning off and then keeping Down+Power keys for going to fastboot not working
How can I enable fastboot mode again ?

I am fairly certain you'd be better off asking in your Lenovo Tab forum, not here in the Oneplus 8 one.

Thank you Nimueh for your reply. I think the issue is not just for a model of cell phone.
Did you ever test this command in fastboot mode? : fastboot reboot fastboot

Why this command disabled fastboot mode ?

No, that's not a command I've ever used, only JUST fastboot reboot

NO idea, sorry.

This did the job for me.

Had this issue on my LG V30 unlocking the bootloader and this worked for me. Looks like a scam, and I'd uninstall it thoroughly after using it, but it did work! I also had to swap to a usb-2.0 hub to get the process I was doing to work so that might be useful.

 

[awdrifter]

Did you ever get it fixed?

Yes, this works to get into Fastbootd, at least on my pixel. Not relevant to the discussion here though
