It's disabled, but turned on right? That's normal behavior for the OEM Unlock menu setting on Nougat. Enable USB debugging then try using fastboot.

That's most like a driver\cable issue. You can't unlock the bootloader without toggling OEM unlocking. Actually it seems there is a posibility found by Bitdomo but for security reasons he didn't shared it.
You're safe if you're unable to change the OEM Unlocking status in Developer Options because that's how it behaves. That's totally fine.
Make sure your download the Factory Image from the Factory Images Website and execute the flash.bat file when you're in fastboot mode.
Let the processes complete and your device will return to 100% stock. Cheers!
I'm sure my cable works. Because it worked first time when I unlocked it(without toggling the oem unlock option) with same cable and laptop. And I'm also sure that there is no driver issue because my device manager shows my device when I connect it in fastboot mode. But "fastboot devices" gives me nothing. I'm tensed and using my phone on stock android without updating any ota updates. I don't know what to do and I'm totally freaking out.
After your phone is in fastboot mode and connected to the computer, try going into control panel - device and printers - right click on your nexus 5x - properties - hardware - properties - change settings - driver - update driver - select manually - select from existing drivers. Now try the drivers one by one and see which one works
Hi,
I'm after some advice, how do I place the Moto G5 in Qualcomm mode or EDL mode.
I have entered the bootloader by holding down and turning the phone on, this allows me to use fastboot.
From there I can scroll down to QCOM, but when I press the power button it boots into the normal system instead of EDL mode.
I have also attempted from within fastboot to use:
fastboot oem edl
fastboot oem qcom-on
fastboot reboot emergency
and
fastboot reboot-edl
Although non of these have been sucessful.
I also have access to an EDL cable, although, when I plug the phone in, then flick the switch 10 seconds later, it does not enter EDL mode, it just charges.
The phone sometimes shows as File Storage Linux USB Gadget in device manager, although it is inaccessible, I have updated the laptop to use the qualcomm drivers, although I don't think it will ever recognise it if I can't put the phone into qualcomm mode to begin with.
Any help would be much appreciated.
What are you actually attempting to do?
This mode is generally used to unbrick a device but you have access to the bootloader/fastboot mode and you wouldn't use edl mode to unbrick this device anyway
It's also used on some device to unlock the bootloader but again you wouldn't do that with this device
So without knowing what you are trying to achieve I can't give you any advice
Technically if you start the phone normally then enable usb debugging in dev options then connect phone to PC and in a terminal window where you have adb set up type
adb reboot edl
Not all devices support this mode though and I've no idea if this one does

Without going into too much detail as to why, there are tools I have access to which can be used to take a full back up of the entire memory block of the phone when it is in Qualcomm mode.
I cannot access adb on the device to use "adb reboot edl" so I am limited to either trying to activate Qualcomm using a button combination or via fastboot, unless you can advise another way.
Any help or a point in the right direction would be much appreciated.

Sounds dodgy to me - sounds like you're trying to access data from a phone that isn't yours so I won't be helping

It's not dodgy, but I fully understand.
Thank you anyway.
try fastboot -i 0x2b4c oem reboot-edl (it's working for LENOVO ZUK Z1 and ZUK Z2)
You can try (if you can/have the TWRP image) to flash TWRP and in reboot options select EDL.
In case the bootloader isn't unlocked you can also use fastboot boot [TWRP image name] to boot directly into TWRP without flashing and then repeat, go into reboot options and select edl.
Not sure if it works for you, if it does let me know that I have helped!

I need help too. So, I own a Moto G5s plus sanders. I unlocked its bootloader the day I got it. Didn't keep any backup and rooted it. I Also installed dot os based on android 11. But my 4G Volte connection was finicky. So, I decided to use a Volte zip patch. But, anyways I flashed the zip via TWRP and tried to reboot. But the phone didn't turn on after that. After a few minutes to my shock I understood that I hardbricked my mobile. No button combos, nothing worked. Anyways in my desperation I found a YouTube video showing the use of blankflash to revive a phone and lo and behold I used the procedure to again restore my device. It booted to the fastboot interface. But my happiness was short lived. My baseband was unknown at this point and the bootloader was I dunno downgraded to 0.5 inplace of 2.12. But, more importantly the unlock status was lost. I unlocked it again and all went well. I could even flashed TWRP. but then I realised I couldn't upgrade my bootloader. I couldn’t do anything. It's always gives a "security downgrade", "preflash validation failed" and "permission denied" error. I even tried RSA official rescue tool from Lenovo but even it was unsuccessful. It was never unsuccessful before that. Not even with a unlocked bootloader. I researched for days and tried custom ROMs. I flashed stock images. Nothing brought back my baseband and IMEI. When I type "fastboot oem unlock critical" it gives me permission denied error with a message. "Need OEM signed bootloader." I think the blankflash bootloader is the root of all evil. I need to change it and therefore I need to enter the edl mode. I have tried all adb commands and fastboot commands. The phone reboots okay after those commands but never goes into edl mode whatsoever. I am also ready to do a controlled hardbrick of my device to go into the edl mode so that I can use my device again with a proper bootloader and a properly working fastboot. Please help
hi guys, i bought g7+ yesterday with 6gb of ram and 128gb rom. It is dual sim and It is the refurbished variant with the mode number G710EAW. i bought it and flashed android 9 pie KDZ and it did successfully.
i always root my android device and i was then looking to do the same with it. i tried putting my phone into the bootloader mode by adb command and my phone just booted normally, then i also tried the volume down nd putting in the cable and nothing happens, it only boots into download mode with cable and volume up, no matter what i try, i always end up going straight into the menu after booting.
Then i went into settings to enable unlock OEM and i was surprised because it said ''bootloader is already unlocked''. i was happy to see that but the problem is that i cant boot into fastboot or bootloader mode so its useless because I'm unable to flash anything, is there any other way via adb to push fastboot commands to get root or any other way? i even flashed other region kdz and it works but i cant get it to boot into fastboot or bootloader, it only works in adb and i was unable to stop some bloat with pm disable command, any help please? thanks
Hi there !
I am writing to you today because I am trying to rescue an ASUS Zenfone 3 Deluxe that is stuck in Fastboot mode.
I am unable to enter recovery mode with the key combination POWER + VOL DOWN (bootloop)
I specify that the USB Debug mode is not activated...
Do you have a solution to recover the data present on it?
I have already tried with fastboot but impossible because it tells me that the phone is locked
ADB doesn't even recognize the model...
I'm listening to you !
Thanks
Same as above. Cannot enable USB debugging because the phone is in a BOOT LOOP.
Only Fastboot is available, down button has no effect.
Phone bootloader is locked and 'FASTBOOT OEM UNLOCK' produces an error.
Hallo i did root with my op 7T EU version HD1903
After root with magisk wasn't working Wifi so i tried to find original firmware and install it with fastboot.exe file.
After this i cant run phone anymore im getting now only blackscreen and after some time i get access to fastboot/ recovery
but problem is i have in recovery restarted system setting and i think it shutted down USB debugging.
If i try find device with adb is then only possible in recovery mode but device is unauthorized .
Phone is without password.
If is there any way to repair it i will be really thankful because im already working on this about 14 hours.
Thanks for every help
Msmtool, EDL mode
