I tried to unlock the bootloader on my OPT, after I had already unlocked and locked it. The phone does not start when i hold the power key, it does not start recovery when I press and hold the volume down and power key. It starts in fastboot mode when I hold the volume up and power, but when I type a command in cmd is says that the device is not unlocked and the command failed.
When type "fastboot reboot" it shows the oneplus logo and the "powered by android" and after a second, black screen, nothing.
I will appreciate it if you could help me....

It's not adviced to relock the bootloader once you already unlocked it.It can cause strange issues.

I have Moto G4 Plus and its power button broke. Now the battery is dead and I am not able to switch it on even with a pointed object. I searched the net and found a way to enter recovery mode. I pressed the Volume down button and immediately plugged in the charger. Now I managed to enter the recovery mode but still, I need the power button to switch it on.
I found another way, but still, it did not work. I installed ADB Fastboot and opened the command window. I remember that I had even tried to root my phone so USB debugging was enabled. But this ADB command window does not detect the phone, even on typing "adb devices". How do Switch on the phone?

I tried with both (vol -) and (vol +) and it went into bootloader.
Try it, Then use command: fastboot reboot
( add "m" if you use mfastboot)
keep vol- pressed then plug an usb cable. leave the vol- in bootloader mode.
then just press power button to start
MI A1 does not enter the fastboot, appears the message "your dvice software cant'be checked for corruption, please lock the bootloader" Two things, first I am layman, I understand little, the other and excuse the translation, was machine translation.
The message has nothing to do with the Fastboot. That message is a normal reaction when the bootloader is unlocked.

Hold the power button and volume down button together for 10-15-20 second, as long as the phone doesn't boot up into Fastboot.

When the message appears, release the buttons and try again to do the same, hold the buttons together for about 20-30 seconds until the phone doesn't enter Fastboot. I Don't see a reason why the phone wouldn't enter Fastboot if you only unlocked the bootloader.

If I hold on, the same thing will happen 10, 20, 50 times, I've already tested it.
If I release the volume - and power buttons, the unit comes in and I have to turn it off to try again :crying:
Can you boot into the system at all? Does the phone work? How did you get to the point that you can't enter Fastboot, what happened exactly?

As I said before, I do not understand much of this subject, the phone works normally, all functions are working, I switched on it some time ago, but I can not remember what I did right for it to be without fastboot

If you don't understand the subject, why did you want to boot into fastboot mode in the first place? No offense, just aksin'.

Good question, did not offend me. I figured it was time to start learning about it, I was thinking of installing the Google Pixel rom
With the phone OFF:
Press Vol- and Power, when Bootloader screen appear just release the power button, so continue to hold Vol- until the fastboot screen.
It's the only procedure for fastboot on our device.

It did not work, the error message appeared and as soon as I released the power button, came on the device. This problem has left many people without understanding, I just did not give up, because I do not accept that only my cell phone this function does not work
Does your phone have root? If so you can use a reboot app from the play store to boot into fastboot.
Install adb drivers, enable USB debug then open command prompt and type "adb reboot bootloader". Phone should reboot to fastboot mode.

LG G6 H871 unrooted
I just can't get into fastboot or recovery mode. I've tried everything on the internet.
I've tried turning off the phone. Holding down the volume down button and then plugging in the USB cable.
I've tried adb command "adb reboot bootloader" which just reboots the phone until I can see the "enter your PIN" screen
The closest I got to the recovery mode was using "adb reboot recovery" which gave me the "no command" screen.
Any tips on this?
Have you enabled OEM Unlock option under Developer settings?
Yes. "Enable OEM unlock" and "USB debugging" enabled.
both oem unlock is on and usb debugging on and my computer has accepted the fingerprint from teh device to shake with adb. . still cant get into fastboot mode.what to do.
Is your phone rooted? If so use flashify to reflash recovery. You do know that if you want to boot in recover you have to let the power key go and repress it once your screen goes on right?
You can also try phone off. Holding volume up while you insert usb cable. Might be a tool that allows a command to be send to reboot it in fastboot mode? If not downgrade its firmware..

If I understand correctly, when you got to the No Command" screen, you were actually in Recovery. From my experience, the No Command screen is like a "greeting", if you will. Once you see that screen, you need to fiddle with the power & volume buttons. I believe the correct combination is to press and hold the power button. Then press and release the volume up button but continue to hold power button. If that is not the correct sequence you will need to Google for the correct order. Reference.
Considering that you are not rooted, there is not much you can do in the stock recovery.
EDIT 2 - Realized that this thread is over a year old and the OP has probably moved on. Didn't realize another member revived it. Sorry.
Hello,
wondering if anyone else has seen this. I turn on the phone into recovery mode, select "reboot to bootloader", hit power button, but it just reboots into normal mode. It won't do engineering mode either. I power off, then press volume down + power buttons, it boots into Factory Test Mode, which is useless. I give it commands over ADB from my computer, using a command line, or using that ADBTools GUI, the phone responds correctly to commands like "adb shell" and "adb devices", but will not boot into bootloader mode. No response to "fastboot devices". I tried every way known to man, but no bootloader mode, no way to root.
i found the software/files by Zachary Pidgeon, but they're not available anymore.
can't think of any other ways to do it.
