Thank you so much for help,i manage to found this thread yesterday
I was installed with Twrp and had rooted my oneplus 3.
I unticked root access in supersu.
Booted to bootloader and typed on my pc in command prompt ,"Fastboot oem lock"
This gave a confirmation on my device,I confirmed locking.
And after that my device did not booted up.I managed to get in bootloader again as I was not even able to open the recovery and unlocked the bootloader once again by this my device booted up.
I flashed stock recovery and repeated the relocking process,this time I was able to open recovery also but no able to boot up.
I again unlocked the bootloader and installed twrp back turned my device up.
Then I unchecked oem unlocking under developer options.
Relocked the bootloader once again.
And now I am stuck at bootloader,not able to unlock it even this time as I turned off oem unlocking.
Now I can only open bootloader.
Please help!

OEM locking a bootloader on a phone that was rooted is a big mistake.
You'll need to flash stock recovery, then flash the stock ROM via adb sideload.
Can be done with this tool http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Thanks for reply

Please help, thanks
how to unlock the bootloader in Realme 5i RMX2030
Here is a good guide that worked for me to unlock the bootloader:

The root part didn't work, Magisk complains about unknow boot image format

I've done the in-depth test and it's on the Fastboot screen but when I type fastboot flashing unlock in a command window it just shows me the help text for fastboot, which doesn't show any command or option for either flashing or unlock, so how can I get it to work if those aren't valid commands?
fastboot devices shows my phone, so the device is recognised.
EDIT: I'm still on Android 9 A.15. I understand that there's no unlocked for Android 10 yet.
EDIT: Nevermind. I was using adb/fastboot from the link in this guide, which is v1.3 https://www.ytechb.com/how-to-root-realme-5i-and-unlock-bootloader/
After I updated to minimal v1.43 from here it worked https://androidmtk.com/download-minimal-adb-and-fastboot-tool
My problem was same. But i successfully downgrade to color os 6. I guess you can try it too.
Enable USB Debugging and Allow unlock boot loader option in USB debugging.
Connect your mobile with PC and use following Command.
adb reboot bootloader
fastbook flashing unlock
Check mobile for unlock option.
How did you downgraded to colour os 6?
I'm trying to root my realme 5i that i upgraded to 10.
Can you help me?

I've recently bricked my device trying to install LineageOS, long story short I had to use MSM Tool in order to flash a new, stock ROM. Since I did that I am unable to unlock the bootloader: everytime I do the phone bricks with this following Yellow message on the screen: "upgrade download failed please check your download flow is right". After that I have to use the MSM Tool again to unbrick the Yellow text.
Any ideata how I might unlock the bootloader? Aside from that, the phone works fine.
EDIT: I managed to fix this by OEM updating my device to Android 11 and *then* unlocking the bootloader. Another issue has arisen now, though: whenever I try to boot TWRP from fastboot, the phone reboots and gets stuck in the "Fastboot Mode" OnePlus logo screen. Would anyone know how to fix this, or maybe is there a way to root your phone without using a custom recovery?

Yes you can ,,install thru boot loader with ADB and fastboot CMD. First you need to extract the boot.img from your oos rom, patch it in magisk app, then put it in your adb folder and run the cmd " fastboot flash boot boot.img .
I just unlocked bootloader on my S7 and was installing magisk and did everything and got the AP patched magisk file etc, and got to Odin and started flashing only for it to fail with this error
Im not sure what to do as this is the correct verison firmware, I unlocked the bootloader, and flashed everything occardinginly
Did you follow the Magisk Installation Instructions?
After unlocking the bootloader, you have to let the device boot and confirm that OEM Unlocking is still available. Vaultkeeper/Knox Guard are still active even after unlocking the bootloader.

Hmm yeah that's what I thought but thought it was already so because...
I unlocked bootloader in dev options but when I boot into download mode it doesn't give me the prompt to fully open up the device it's just normal download mode :/
I tried booting into recovery and "restart to bootloader option" doesn't even exist, so I had to do it via pc
What should I do?

The OEM Unlocking toggle in Developer Options does not unlock the bootloader on its own. It's simply a "safety" that when enabled allows you to unlock the bootloader.
When you're in download mode, do you see "OEM LOCK" near the top of the screen? Does it say "On"?
To unlock the bootloader, unplug any cables and shut the device down.
Then, hold both VOLUME buttons, and while holding them, insert the USB cable from your PC. The device should start with a prompt - Volume Up for download mode, long press Volume Up for unlock mode, and Volume Down to cancel. Follow the prompts to unlock your device. This will wipe all user data.
Once you've unlocked the bootloader, follow the instructions in the link I posted to ensure Vaultkeeper/Knox Guard are fully disabled.

When I boot into download mode it just shows a normal download screen with no text in the top left, no nothing, it's just normal download. I don't get the option to unlock the bootloader as I've said in my last post
