I loaded latest android drivers, and successfully accessed the phone with "adb devices". The phone is OEM unlocked in the settings and USB developer mode is set. On issuing "fastboot OEM unlock" or "fastboot flash unlock", I got a (tiny) message on the screen that said something like " the serial is not match ....., fastboot_verify_unlock fail". After 2 seconds the message disappears and reboots when the power button is pressed. The RealMe UI native boot screen has an option to load a .img file. Could I use this to load a TWRP or other bootloader? Any clues?

To regain root, simply use
Code:
fastboot boot
and drag and drop the TWRP file and press enter, and install root of your choice.

This is 2 months late, but if you're still looking for a possible solution, this is what I did:
1.) Download the tools you need here: https://developer.android.com/studio/releases/platform-tools/ and extract
2.) Install LG United Mobile Drivers from here: https://lg-united-mobile-driver.en.lo4d.com/. I recommend uninstalling previously installed LG G4 drivers from Device Manager and then reinstall from that page. You may need to install additional drivers once you connect your G4 to your computer.
3.) In Developer Options, make sure you have "Enable OEM unlock" checked and "USB Debugging"
4.) Open a command prompt in the tools directory (hold shift, right-click inside the folder, and click "open command prompt here." If you've authorized your device to be recognized by your computer (two prompts should popup: one to allow USB connection and another to allow USB debugging), your device should be listed if you enter the command "adb devices"
5. Enter "adb reboot bootloader"
6. Once the phone has rebooted into the bootloader, you should be at the stage where you get the text on your phone, as you described. Enter "fastboot oem unlock"
7. Check if you've unlocked the bootloader: "fastboot getvar unlocked"
8. If successful, you can then go on to flash TWRP onto the recovery partition and root your phone by flashing Magisk from there.
Hello .. I have a LG G4 811 t mobile32GB phone, what is the appropriate flash?
Hi, so my Xiaomi MI A2 is kinda not working and I think that wiping cache partition might help but I can't access the recovery so I wanted to install TWRP. The thing is I have the boatloader locked, I have the USB depuration activated but not the OEM, so how can I unlock boatload or unlock OEM via fastboot?
Thanks

V40 on startup: "Your device has failed a routine safety check and will not boot."
I was following this guide to try to flash a US firmware on my bootloader-unlocked Sprint V40: https://forum.xda-developers.com/lg-v40/how-to/guide-make-lg-v40-compatible-lgup-t3953120
After issuing the command "fastboot.exe set_active a" then powering off and trying to enter download mode, I get "Your device has failed a routine safety check and will not boot."
It briefly goes into download mode after that (for just a few seconds). Then I get a green screen with black text that says "LGE Crash Handler : FIQ : NOC Error!" and has a whole lot of other diagnostic info.
my one says all slots are unbootable

You have to restore your software again and re-root
Hold Volume+ and plug the phone to your PC to get it into download mode. Use LGUP to reflash the firmware.

I too have this problem, i can get it into fastboot mode, and the other mode with the blank screen maybe its 9008 mode (EDL Mode) i do have an EDL cable would that help with anything?
When i press Vol + and insert cable from phone being off it doesnt go into downlaod mode only back to boot loader mode, not into download mode
Its funny its a LG G7, but its showing LM-V350EMW

Will keep persisting
still cant get into download mode, it flashes up once i turn off phone, press vol+ and insert cable i see the image of download mode then straight into fastboot it goes
Hi guys,
I've a leeco le2, it's in some sort of bootloop. I now have a phone which I hope is not actually bricked.
To cut to the chase:
The phone boot loops - it shows the "Leeco" on the black background for less than a second, then reboots, after 2 seconds, it comes back up with the "Leeco" and reboots, and so on.
I can get into fastboot mode. Interestingly, the status shows "Device is LOCKED"
I cant get to recovery mode. It just goes into the boot loop again.
Using the adb tools, I cant issue the "fastboot flashing unlock" or "fastboot oem unlock" commands because it returns: "FAILED (remote: 'oem unlock is not allowed')"
I am unable to get into the phone OS to change the settings because the phone is boot looping
. I am flashed several time in flashone,qfil and Miracle thunder but problem is same.
Given the fact I am unable to get to recovery, I am unable to sideload an OTA zip. And given the fact that I cant boot into the OS, I cant enable oem unlocking.
Do I have any hope at resurrecting this phone in any way? please help me

Developer Mode enabled

Below are screenshots of all of the above

Phone is recognised by ADB but not Fastboot and as such I cannot unlock the Bootloader. Is there something I've done wrong or something else I can try?
When entering "Fastboot devices" in CMD nothing comes up.
When entering command "ADB reboot Bootloader" in CMD the phone restarts instead of loading into Bootloader.
I have tried turning phone off and the pushing power button + vol up - this just keeps restarting phone.
Any help would be much appreciated as I'd really like to root this phone all extra info in images on Imgur. Link above.

Did you find a way? I tried everything but I couldn't get into fastboot
No way to enter fastboot mode for oppo phones. Now I use Oppo A74 4G version. Cannot enter fastboot mode. It's locked by Oppo. And they don't give bootloader code for unlock BL. Only way is to change phone
I've been trying run fastboot too. 4 hours later I find this thread. That explains it
Last Oppo phone I buy I guess.
Did you manage to find a workaround for this by chance?
Has anyone tried rebooting from recovery to then enter fastboor or?
Im gonna look into myself soon...
Ive seen this issue before on a different phone but cant remember how they bypassed it
Perhaps yall can try to find a post where they did so.. maybe it'll work on this phone too.
I was able too get to fastboot mode. The phone labels it "recoveryd mode", however, fastboot commands work.
1st. Connect phone and confirm ADB is connected by using "ADB devices" command.
2nd. Enter "adb reboot fastboot bootloader"
Phone will reboot into "recoveryd mode". It looks exactly like the normal recovery mode except the title displayed after you select the language and fastboot commands will work.
However, I still have not found out how to unlock the bootloader, so it does me no good.
try doing adb reboot fastboot or adb reboot bootloader
fastboot oem unlock
FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed
guys ,, fails
when trying to boot to fastboot and not fastbootd
