Additionally I see below device information. Does this mean that I am using ATT unlockable bootloader which is refurbished into H811?
PS D:\MobileData\Abbu\platform-tools\platform-tools> .\adb.exe devices -l
List of devices attached
LGH810cdd7f415 device product1_global_us model:LG_H811 device1
My phone just reboots on command (adb reboot bootloader) instead of going in bootloader.
Both usb debugging and enable oem unlock are checked in developer options. Thanks

only one way to find out... or get a refund..
open up phone take motherboard out and read model number in plate. if its h811 and your pictures say antirollback V3 then you can flash 20o KDZ but latest its 20v.

Any way round "Check 'Allow OEM Unlock' in Developer Options" ?

The latest M 6.0.1 OTA update left my Nexus 6 in the "corrupt" state. I am trying to install images with fastboot, but 'fastboot oem unlock'
gives me
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
As it won't boot that far, I can't get to developer option. Is there any other way to enable an OEM unlock?
only if you have twrp which you can search a thread on it because I don't have the exact info on that.
this thread may help

The link in Kam_el's post works for me (though not the one in your post: it is missing the middle part).
To summarize my understanding:
- if your phone has a working recovery, use adb sideload
- if your phone has an unlocked bootloader, use fastboot
- if your phone has a locked bootloader, and neither the rom nor recovery works, then it is hopeless.
Yes absolutely your thinkings are right

OEM unlock toggle grayed out after emui 9 upgrade

I'm in a bit of a pickle here.
I have ran the update for emui via twrp
Then ran clean system os reset
In fastboot menu the Phone is unlicked but other one isnt.
OEM unlock inf grayed out says to contact to network which i am. Twrp is no longer installed and im unable to downgrade or even re-root the device.
Any ideas?
Would have recommended to read the various threads about Emui 9 already posted here before you decided to upgrade. Currently there is no working twrp and no working root available for Emui 9. It is easy to brick the phone if you try to force install twrp and root it.
OEM unlock is now disabled by default on all Huawei phones running Pie to discourage rooting.
For the time being just use the phone as it is. If you really want to downgrade then there is guide here:

Nice one thanks a lot.
I have unlocked the bootloader prior to upgrade, does that mean that it's locked again?
Never do factory reset on pie. It's written everywhere.

Can't unlock bootloader

I have tried over and over again to unlock the bootloader.
I've signed into my Mi Account, the same on both my PC (Mi Unlock Tool) and phone.
I installed the Xiaomi driver.
I click unlock, and then it gets to 99% before saying Unknown error (-1)
I've tried on two PCs, one AMD Ryzen 2nd gen, one Intel Core 6th gen.
After trying on the Intel PC, the phone is no longer detected by the Mi Unlock Tool, on both PCs
I really need help with this
What version? Try to another.

Try to 2.3.XXX
Check if your phone(fastboot mode) is detected in device manager as well.

Whenever I connect my phone while MiFlash is open, the phone instantly exists the bootloader, but stays on the bootloader if I reconnect it.
Edit: I also tried MiFlash 2.3.803.10, but my phone is not detected there either.
IT FINALLY WORKED when I disabled device signature enforcement on Windows.
Thanks for the help guys.
EDIT: IT DIDN'T BLOODY WORK. The unlock tool said successfully unlocked. When I check on the phone and through typing 'fastboot oem device info'
it said the phone was not unlocked.
EDIT #2: All of a sudden it just worked on my Intel PC with the newest version of Mi Unock

Hello. No, I could not solve the problem. One person restored the firmware through blanflash using files from https://mirrors.lolinet.com/firmware/, but I did not succeed. You may need an updated blankflash.
