Hi guys,
I'm having problems unlocking bootloader.
The phone enter into fastboot mode but when I type "fastboot oem unlock-go" in the cmd of windows it doesn't recognize my device.
I have installed Minimal ADB and Fastboot and I have installed ADB Driver installer too but it doesn't recognize the device.
Can anybody help me with this please?
I need to unlock it because I want to root it.
Thanks
Have you tried unplugging and replugging when the phone goes into fastboot mode?
I just got my pro 3, did the OTA to the .19 software and unlocked and rooted just today and my girlfriend's very very fresh windows 10 install.
If that doesn't work just delete the adb driver, replug the device and windows should install the same drivers I used.

Windows 10 Home on host computer, and ADB tools installed.
USB debug mode on and host computer allowed.
USB PTP mode.
LG Unified Driver installed.
I opened command prompt, locate adb platform-tools. Ran the following commands
Code:
adb reboot bootloader.
The phone rebooted to bootloader.
On the bootloader mode on the phone, I typed
Code:
fastboot reboot
The phone rebooted properly
Does it work right?
Currently the phone is not ready to unlock bootloader until there's no problem, especially speaker problem, found.
Hello!
I have a very big problem. My LG Leon H340N is "bricked" totally, there is only fastboot mode in phone, nothing else.
The problem is that fastboot is not working, when i try to execute some commands it all the time gives me answer: FAILED(Unknow Command) and i don't know how to fix this, i don't have access to download mode, i don't have access to hard reset menu, i don't have access to recovery mode, only fastboot
Could somebody help me ?
How did you get into fastboot mode?
I connect device and laptop via USB and device is starting into fastboot mode automatically.
When device is connected i open cmd (run as administrator) and C:\ cd adb = C:\adb> fastboot devices - and it shows me my device connected as fastboot device then I try to execute some commands but it always gives FAILED(UnknowCommand). The fastboot drivers are installed - original google drivers from android sdk. I'm using Windows 7 Home Premium, i try execute some commands on other laptop with windows 7 starter but the same thing - FAILED(Unknow Command).
Thank you for reply, Regards

I don't have MetroPCS version it's h340n. And i can't flash anything, because fastboot is not working

Hi All,
Trying to do what should be simple - install TWRP , then omnirom.
Have a new le pro 3, running stock firmware.
have enabled usb debugging, enabled oem unlock.
I can see the le pro 3 in adb devices. I then reboot (adb reboot bootlader).
Phone goes into fastboot. But fastboot devices, or any other command cant see the phone in fastboot mode..
Appreciate any help.. I'm at a loss. Thanks!
Even if ADB show your empty list, when you're at bootloader you can flash TWRP... Look my thread about brick.
Do it with flashing guide... You should also unlock in bootloader mode. And check the status.
For anyone that cares - on a Macbook pro retaina (with windows 10 as VM) - I could only see phone in adb, not fastboot.
installed fastboot for OSX, and ditched the virtual machine, and voila.
I want to install LineageOS so I closely followed the fastboot and adb instructions on the official site. During my first (failed) attempt, there were some old Google USB and ADB things on my PC, so I deleted everything and started again with a clean slate.
I managed to make ADB work (adb devices detects my device, could authenticate the computer, all seems good there). But if I start the phone in fastboot mode, connect and run fastboot devices, I get nothing back. It doesn't give any sign of the connected device. Windows's "Devices" window lists a device called "Android", but it's under "Unspecified" and has the yellow triangle/exclamation mark on the icon.
1. Am I right to assume that this will stop me from unlocking the bootloader (if I will use the unofficial method) and flashing TWRP and a custom ROM on the device?
2. More importantly: What could be wrong, how can I make fastboot see my phone?
Many thanks for the suggestions!
hi,
first do you have latest ADB and Fastboot
then connect your device and run adb devices. check if it detect the device means from the command prompt run "adb reboot bootloader" (without quotes)
now once after device reboots to bootloader check fastboot devices it will detect now
if not then goto device manager,right click on the device and click on update driver software and choose android fastboot interface
you are done now run fatboot devices,it will detect the device
Solved!

is there a root method for this version ? I try to unlock bootloader but when I open CMD type fastboot unlock OEM it said waiting for device. I already instal abd and OnePlus 6t driver so i don't know what else to do. Please help me
What I usually do is leave my OnePlus 6T unplugged from the computer, and run "fastboot oem unlock" or any other bootloader commands in terminal, when it says "waiting for device", I plug it back into the computer, the command will be processed. It's a bug in the bootloader.
***EDITED*** If the phone is still stubborn, just reboot it back into Fastboot Mode, and do above, it will finally do its job.
