No, I have not solved the problem. The tablet is not loaded, and I can't flast it.
My advice: Allow OEM unlocking the bootloader in the Setting

sad...

I need to find an OTA update on flash recovery. But I can not find it ((

are you using the new unlock command.?
you may also want to update the sdk or whatever adb/fastboot package you use.

you were saying that pixel c would not unlock and i was asking if you are using the new unlock command. the pixel c uses the nexus 6p unlock
command. not the old one.
it is no longer "fastboot oem unlock"
it is now for pixel c "fastboot flashing unlock"
you need to update your fastboot/adb package you use in case the one you are using does not recognize the new commands.

Unfortunately this does not work (

Maybe you need to install ADB USB driver manually.
Once fastboot is working .. fastboot flashing unlock

generally that message is shown when the allow oem unlock switch in developer options is not set on.

but I can not set it in Setting, because my device is not bott

well, if you still have the device then one possibility is to post your issue to this group,
https://groups.google.com/a/chromium.org/forum/#!forum/chromium-os-discuss
to see if there is a flag in the vbnv that can be set with fwtool. [similar to fastboot issue] to get it to boot.

Fastboot refusing to take commands after oem unlock

I recently used the newfound method of unlocking the Verizon Pixel/XL 1 to unlock my Pixel XL. The issue now though is that I can't flash anything, or do anything in fastboot. Windows doesn't see my device when I use adb reboot bootloader, and the console entry on the bootloader screen says DISABLED. Google is unhelpful as I seem to be the only person here with this problem. Any ideas?
For what it's worth, I used fastboot oem unlock instead of fastboot flashing unlock.

Update options not listed in config, and no OEM unlock listed in Dev Options

The title pretty much describe the whole issue: I get a persistent notification that there's an OTA update to install, but touching the notification does nothing.
There seem to be no way of manually installing it either, because there is no update option listed in the configuration.
Can't unlock the bootloader either, because there is no OEM unlock listed in the dev tools.
I've never seen anything like this. Spent days researching, but found nothing. So here I'm hoping someone might have a clue about how to enable updates and OEM unlock in a situation like this.
Any help is appreciated.
This phone is a Xiaomi Mi A2 Lite model M1805D1SG, running Android 8.1 (OPM 1.171019.019.V9.6.6.0ODLMIFF)

for unlocking the bootloader you have to use ADB tools. you can't just unlock it in developer setting.
for your problem i would recommend you too check the forums on how to unlock the bootloader with adb and then grab the latest official A2 lite rom (10.0.40. or something i guess) and flash it with the MiFlashTool.
this procedure will upgrade your device without any loss of data.
I'm telling you this because that's how i update my device (which is rooted and kernel modified) with no problems.

True. We usually need to run 'fastboot oem unlock' to actually unlock the bootloader. Problem is, the command needs one to enable OEM unlocking in the developer options beforehand, otherwise it fails. And I dont have any means to enable OEM unlocking in the dev options, because it is not listed at all!
And without that I'm unable of doing any flashing.
The only report I found regarding a missing an OEM unlock option in the dev tools concern Samsung S9. Apparently one needs to wait 7 days for it to appear. But such a thing is unheard of concerning a Xiaomi phone.

I'm on 9.6.11.0 version and it's there. You're on 9.6.6.0 version. Maybe there's someone who had experience with 9.6.6.0 and OEM unlocking but if not there's always the option to do an OTA update to a newer firmware version.
Just don't update to a 10.x.x.x version (Pie) if you want to keep Oreo

I'm guessing when Google told you that all phones coming from Google were fully unlocked they were talking about being carrier unlocked instead of having the capability of unlocking the bootloader.
When buying a LG phone (e.g. Pixel 2 XL) it's good to have the seller run an IMEI check and post the screenshot for you from this site... https://www.imeipro.info/check_lg.html
Under they buyer name you can tell if you are getting a Google or Verizon variant.

Since all Minimal ADB and Fastboot does is bundle up the platform tools and add a Windows executable stub to them, removing it isn't a bad idea. An alternative - that I took - would be to update the platform tools in the Minimal ADB folder with the latest from Google.

Officially no, but for me and several others it still worked, even with an EU phone.
I had to upgrade to Android 10 and then follow the steps described here:
https://c.realme.com/in/post-details/1244566811094024192?language=en-US
Btw., it's better to stick to the official post from realme I linked above, apps and links on youtube could be malicious.
I am using RM5P Indian version. The youtube link is safe. I didn't find any issues.
More than that, this apk was already listed in xda by faisalxp. I realized that late.

Yes, that's exactly what I was on before unlocking and rooting (INDIAN version).
Install adb and fastboot drivers in PC.
Good practice is to put all the necessary files in the C:/adb folder for installing twrp recovery.
Backup your data/pictures/notes etc first to pc.
Enable OEM unlock in Developer options. Enable USB debugging.
Install deep test apk and follow the instructions and get into FASTBOOT.
In fastboot type: fastboot flashing unlock and enter, and then unlock.

Yes, you can use the app prompt "Apply to exit in-depth test". It will reboot to Fastboot where you need to type the command to lock.
Fastboot help - will give you all the commands available.
Commands available:
locking/unlocking:
Fastboot flashing lock|unlock Lock/unlock partitions for flashing
I suggest you research a bit more. Phone might get bricked. Do it at your own risk.
You should not be on TWRP, go back to official recovery.
If you have rooted, UNROOT first and do the rest.

Actually when i press that button it shows this "You can only apply to exit in-depth test after carrying out bootloader lock operation in fastboot mode".
so I went into fastboot mode and used the command fastboot flashing lock it wiped my data and rebooted to welcome screen (language region setup)
Should I now use the app to "Apply to exit in-depth test"? or don't use the app?

What are the steps you took before relocking the bootloader?
In my experience, relocking the bootloader should be the last thing you do, after you've got a working/bootable stock ROM.

So, the OEM lock/unlock thing comes with a pretty big caveat, and you need to be aware of it: loss of data.
Every time you lock or unlock your bootloader, a wipe data is triggered.
Now, for as far as I know, to lock the bootloader, you need two things:
1. Stock ROM. Don't do this on a custom ROM!
2. following command, in Terminal/Cmd Prompt
fastboot oem lock
Of course, you need to be in fastboot mode, so if you're not, and if you're booted and connected via USB (USB debugging needs to be ON and RSA fingerprinting accepted), do:
adb devices
It should display your device here. This is just to make sure ADB is working properly.
adb reboot bootloader
At this point, the phone should reboot into bootloader, so now you can do the lock command
fastboot oem lock
Data should be erased and, in case it doesn't automatically boot up, you can reboot the phone.
Don't worry about the OEM unlocking option in Developer Options. You just make sure the stock ROM is functional before attempting to relock the bootloader.

no, i run the command and it asks for changing the oem lock setting in developer options, i reboot the phone and run through the setup process. Then when i enable developer options and check the oem lock option, it is greyed out.
Is it greyed out in the on or off position? Can you attach a screenshot? I don't remember the operations sequence... But I think the option was automatically switched back to the original position (off) when you lock the bootloader. I could be wrong though. So...when you run the "fastboot oem lock" command, it asks you to....what?
Set the option to on or off? Some screenshots from both the PC, with the message, and the developer options might help to clarify this.

A screenshot would be really useful. But don't worry about it. When you're back to stock rom and ready to lock your bootloader, we can resume this then. I think either we're missing something, or it's everything ok, and you just need to switch that option off. Though, I remember I didn't have to do it manually. But I could be wrong though.
So, don't worry. Enjoy LineageOS and we can resume this when you're back to stock ROM and ready to lock.

so after running the fastboot oem lock command, it asked this in the cmd
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem lock
...
(bootloader) Check 'Allow OEM Unlock' in Android Settings > Developer
(bootloader) Options
OKAY [ 0.080s]
finished. total time: 0.080s
when i rebooted the phone, it showed the screen saying that the bootloader was unlocked. also i had to re run the command because it was going to erase my phone but that din´t happend, after going to developer options the option was still greyed out.
The last 3 days i've tried some roms from here.first i've unlocked the bootloader in developer menu,then from fastboot with the unlock key provided by motorola website,i've tried different rom,didnt like that i cannot use bank apps.so i went for locking.full reset,adb enable,reboot bootloader,full flash stock rom (last one from Motorola),reboot to check,adb enable, reboot bootloader,run command " fastboot oem lock " once ,it asked for confirmation due to data loss,then run command " fastboot oem lock " once more,then reboot to os.everything went ok,device dont show that was unlocked
