How to prevent unlock bootloader (Newest build V10.0.17.0 android 9) - Xiaomi Mi A1 Questions & Answers

I just reflash my Mi A1 to latest build android P V10.0.17.0. But I relized I could still unlock boot loader though I didn't enable OEM unlocking in Development option, I just boot to fastboot mode and type fastboot oem unlock and it alway OK. I also turn on Find device or set passcode.

hmm... maybe a factory reset would work but if you want to relock your bootloader I strongly suggest backing up app data using TWRP.

Yes, I already backup data. But I don't know why it can be unlocked while not allowed.

OEM Unlock can't be enable in fastboot / ADB, you'll have to reboot into normal mode, follow steps described in the link I've provided, and reboot into fastboot mode. Be aware too that that OEM Unlocking your phone will wipe your data (App, Pictures, etc).
Oh yeah, please, SEARCH next time, PLEASE, PLEASE, PLEASE!!!!!!

First off whats FRP? and if the phone is locked at this point and you cant boot it you will not be able to unlock it sorry but on the other hand you dont need an unlock bootloader to flash a stock rom but once again if the phone is locked even after you flash the stock rom it will be locked still. Sounds like you found someone phone maybe you should return it
I am in same situation. Can't boot rom adb not enabled, bootloader locked.
I cannot flash anything via fastboot, if only I could enable adb some how
Do you have USB Debugging enabled?
If you are stuck at factory reset protection you should probably enter into it using the Google credentials or your pattern.. If you don't remember them its fine. But if it's not your phone, please return back.
@ewalk4866 frp is factory reset protection that is introduced in intention of avoiding data stealing... If you reset your phone when it is locked, you have to input your old password or pattern to get pass through lockscreen pattern.

Unlock bootloader

I normally receive my phone in few minutes, for unlock bootloader, i must activate debugging and reboot bootloader and fastboot oem unlock? When twrp is available just fastboot flash recovery twrp.img?

In developer settings I believe there is a second toggle you need as well. Something like Unlock OEM bootloader. Select that and then you will be able to use the fastboot command.

yes i see it and unlock my bootloader with command line

OEM unlock toggle is not working

Hi.
I´ve unlocked the bootloader on my P10 plus.
But now, the toggle to unlock OEM on the developer settings is greyed and I can´t perform any fastboot commands.
Any help?
Thanks
I believe the option becomes disabled when you've unlocked the bootloader, as you'd have to use the relock command instead of the toggle to relock it.
I assume you're familiar with accessing and using fastboot if you've unlocked your bootloader... so for the fastboot commands, does the device show up when plugged in and you run "fastboot devices"?

i have my huawei p10 plus doing the same thing of yours.....only erecovery mode and when i get to boot in fastboot mode is only fatboot mode & rescue and i had locked bootloader and frp lock.....but i was reading that huawei just block the page to unlock bootloader i just dont know why they did that /......
Maybe try re-unlocking and flashing stock rom, kernel, system, and boot. (Or you can try the method I used to update manually). Requires to be able to acces external sd card.
Hmu if you want to know how.

You must have stock recovery...
A booting system..
Your bootloader unlock code...
Make sure you can boot to your system first:
1.Do a factory reset using stock recovery
2. immediately after doing the factory reset go to bootloader and relock your bootloader
fastboot oem relock xxxxxxxxxxxxxxxx
3. Boot to your system and go to developers options and enable oem unlocking
If you try to use TWRP for the factory reset you will brick your device
It has to be the stock recovery.

erecovery and dload mode are not useful in this situation...you can use DC PHOENIX alternatively

Now you have to boot to the system and re enable the OEM unlocking (frp)
And reunlock the bootloader

Cannot boot Mi A1 after locking bootloader

Hi could I ask because i lock my bootloader on Mi A1 but unfortunately the device didn't boot up.
Now, I am trying to unlock bootloader to fix my device and it won't unlock FAILED (remote: oem unlock is not allowed).
I am on May latest security patch build. Please help me.
Did you try reflashing ROM with Mi Flash tool? Use "Save user data" option there.

I think you tried to lock your phone after rooting your device. You'll have to try to switch to fastboot mode by volume down + power after vibration. Then use flash using Mi flash tool
I cannot do that, the bootloader is locked and I am on May security patched. Those fastbook oem unlock and fastboot flashing unlock methods won't work. I believe only testpoint is the solution to my problem.
Stuck with the exact same problem....did u find the solution

Reboot to fastboot power+volume down then reboot to edl mode by typing "fastboot oem edl" in your adb your phone will turn black. Open miflash and click "refresh" if you see "com#X" it means its connected then flash the fasboot file you downloaded in mi forums after finish press and hold power until it restarts.
