enable oem unlock is on, in adb whenever i type adb reboot bootloader it just reboots. What should I do?
I have the exact problem. I can't figure out what to do. I've tried every possible method online.
You need to hold Volume+ while rebooting.

Im trying to get my phone back to stock to return to sprint tomorrow, but i cant access bootloader or download mode through the hardware buttons. I was able to reboot to bootloader once through adb using adb reboot bootloader, but after removing SU whenever i try i get a message "reboot: operation not permitted". No matter how many times i try to access bootloader by pressing vol down and power it just boots straight to OS. any ideas?
nvm. apparently reboot from within adb prompt wont work, but a straight "adb reboot bootloader" from cmd works just fine. weird.

It's VOL UP btw.
So my Nexus6p randomly restarted once (I had been on 7.0 since release date with no issues) and since then is stuck in bootloop on the Google Logo.
Holding the Power+Volume Down boots into bootloader. From there I can't get to recovery or even tried the factory reset from there and it always gets stuck on the Google Logo.
I have downloaded the SDK and while fastboot works, adb doesn't.
I can't flash anything through fastboot because boot loader is locked. I can't unlock the booatloader because remote oem unlock is disabled. I have never had the need to root or unlock bootloader, so never had USB debugging or allowing unlock checked under debugging tools.
Can't sideload OTAs since adb doesn't work.
Do I have any options to recover the device and make it work again?

Do you just have stock recovery? If so, can you boot directly into it with power + vol up. If so, maybe try hitting stock recovery menu to side load ADB or factory reset? Otherwise, sounds pretty borked unfortunately.

I am using Oreo.
But there are too many bugs.
So I want to downgrade.
I want to go back to 7.1.
I tried to find a way.
I do not really know.
Press Volume Down + Power to enter fast boot mode.
With ADB, if you use 'fastboot devices'
Nothing happens.
Developer option, OEM off, all done.
I want to know how to downgrade.

Follow the instruction provided by Essential:
https://www.essential.com/developer/current-builds
Developer otpion and OEM unlocking are off? Why? That shouldnt be needed.
Download current build from link provide above ^^(current build)
extract the files to your "adb/fastboot/platform tools folder on pc"
connect the phone to computer using usb cable.
Open adb on computer
type adb reboot bootloader
when in bootloader verify fastboot works
"fastboot devices"
if your device shows up double click the flash all script for your OS.
Profit
Hi
By me the same.
When I Type adb reboot Bootloader the Phone starts new and boot up the system.
When I manually Boot into Bootloader the Phone were not found in Fastboot.
Developer option, OEMunlocking , all on.

I had the same problem. adb worked, fastboot did not. Installing the PH-1 drivers from the Essential support site fixed it.
Hi, i have a weird issue. Whenever i boot my phone using the power button it just goes to fastboot mode. From there i can start the phone pressing start with the power button so i have no problems at all, it's just that it forces me to go to fastboot everytime i want to turn it on. How can i fix this?
I have to state that i am on custom rom 8.1 pixel experience xt1687

You are in OEM fastboot mode most likely, clear it with:
fastboot oem fb_mode_clear
And then reboot... Should go straight to OS. Otherwise, include a getvar all, it will tell the reason for going to fastboot.

Much thanks that worked .
Mine reboots into recovery every time. It doesnt matter if i power it up, or just restart, but he restarts into recovery every time, and to start it i need to reboot into bootloader (from recovery) and then start it from a bootloader.
Will the same fix work? Also, where do i type that?

Your problem is different. You need to use ADB with phone hooked to your PC, and execute the following commands.
Code:
adb devices
adb shell
dd if=/dev/zero of=/dev/block/platform/soc/7824900.sdhci/by-name/misc
or execute the last line in a terminal shell inside TWRP.
Code:
dd if=/dev/zero of=/dev/block/platform/soc/7824900.sdhci/by-name/misc
Currently, I am trying to unlock bootloader using adb.
I installed adb and fastboot and checked everything until the CMD shows my device correctly.
And right after I type
"adb reboot bootloader"
my tablet just restart and does not go into the bootloader mode.
I also tried it manually, by pressing home+up+power button, but it also perform restart and no bootloader mode.
Does anyone knows why?
I checked all the settings in developer mode and cannot figure out why.

You can't unlock the bootloader with adb only with fastboot which doesn't work on Samsung. To unlock the bootloader on Samsung you have to enable OEM unlocking in developer options. Also Samsung doesn't have bootloader mode but instead they have Download mode which you can use tools like Odin or SmartSwitch to flash files. To get into Download mode use the command adb reboot download or use the button combination power + volumn down + home.
