Hello.
Normally after relocking the bootloader on these phones it will say relocked. While debranding my phone I had the phone bootloader unlocked and rooted, with the untrusted boot up message. Half way through the debranded procedure I had massive issues with encryption and it not letting me past which took an age to sort out.
Once I passed that I managed to finish debranding the phone, but after flashing the the new firmware to the phone I stopped seeing the unlocked bootloader message, when I hadnt relocked the bootloader. When I checked, the bootloader was locked and frp was unlocked.
Everything is working fine with the phone, receiving updates, all themes working, everything working great.
I just don't fully understand how it's relocked itself, but Instead of it showing relocked it shows the original locked, but frp is now unlocked while the phone is locked, both originally said locked.
Anyone have any ideas. ????
Same for me
Look at
http://forum.xda-developers.com/p9-plus/how-to/guide-how-to-lock-unlocked-relocked-t3465486
Did you find out why frp doesn't go back to locked Instead of staying unlocked. I only ask because my NatWest app says i'm rooted or security settings have changed and won't let me log in via fingerprint. I wonder if it's because of this. ????
Edit. If you remove USB debugging and OEM unlock it relocks the frp lock.
Good thank you for sharing it
Hi all,
I've purchased a used P20 Pro from a friend which has an unlocked bootloader and has been previously rooted. I normally keep my phones stock so I want to lock relock the bootloader (I have the code) but despite trying to follow various guides I have been unsuccessful.
Would anyone be able to guide me through the process of relocking the bootloader please?
The main reason I like to keep stock is manufacture updates etc and I don't have the knowledge to maintain a rooted phone.

I don't believe that an unlocked bootloader will prevent you from getting updates. As far as I know the only difference is the warning you get when you boot that "you can't trust the phone."
IF YOU BRICK YOUR PHONE IT'S YOUR RESPONSIBILITY
Don't know if there is another way but of you have fastboot and adb you can do it:
1. Make sure developer options are enabled
2. Connect your phone to the computer using USB cable.
3. Open a command window and type 'adb boot bootloader'
4. Once the device has booted into the bootloader mode type 'fastboot oem lock'
This WILL ERASE all your user data and you will have to configure everything from scratch. You will need the unlock code if you ever want to unlock it again so make sure you don't loose it.
Hello Community,
i have a Problem after the installation of the newest android Update (OTA).
The A2 just Boot till the white AndroidOne Logo and it hangs there after a time it seems it shut down itself.
My Device:
-USB Debugging is disabled, its a new testing device.
-I cant boot in recovery mode (vol-UP+Power) just boots to the white androidOne Screen and there it hangs
- I can enter fastboot(VOL-Down+power) mode and the device is listed when i type fastboot devices in my terminal on pc
- when i fire up MiFlash tool it list my device after clicking refresh, if i want flash the latest FW (http://en.miui.com/download-353.html) i get the error:
error:"Flash bluetooth_a error"
- My bootloader is locked.
Question:
How can I flash a offical Android with a locked bootloader?
is it a good idea? or better send it back for a warranty solution (i dont want wait)
is there another way to solve my problem? i really dont know whats the problem is. i did not rooted the device or anything.
would be lovely if someone could help me. with an instruction what i can try.
Thank you very much and have a nice day
Regards
If you have enabled 'OEM Unlock' setting in Developer settings, you will probably be good, you can unlock bootloader(oem/flashing/critical) and flash the official ROM ( as per now, 10.0.2.0 )
If not, you have 2 options
-Boot into EDL using short points and flash from there
-Warranty
Same thing happened to a friend's phone, it wasn't touched and just went brick after 10.0.2.0 OTA.
Guess everyone should enable 'OEM Unlock' in case this happens(Data Encrypted anyway, worst case stolen phone better than the chance of brick every time an OTA comes)
edit: If you want to save your data, you obviously shouldn't try the bootloader unlock way...EDL flashing allows flashing without wiping data, but haven't tested that personally
wow really? that are bad news...
thank you anyway :crying:
maybe someone other got a idea?
regards
Lot of users faced this after today's update including myself. Since my bootloader is locked, only option left is EDL flashing by connecting motherboard test points.
Just an advice for everyone reading this message from a Xiaomi Android One device: ALWAYS KEEP UR BOOTLOADER UNLOCKED, IT DOESNT MATTER IF USB DEBUG ISNT ACTIVE, JUST UNLOCK BOOTLOADER
sorry for caps, is just an important thing, i also had the issue but with unlocked bootloader i solved it easily
Just flash using fastboot

that seems not possible with a locked Bootloader (very new phone)
or can you provide a working solution with a locked bootloader? i wont use this EDL thing because its just new and i dont want open it.
Thank you all anyways
Try with this tool : https://forum.xda-developers.com/mi-a2/development/tool-mi-a2-xtrem-toolkit-t3879660
(edl included)
Same trouble here, we are fu...ed!
With Xiaomi mi flash tool, you can re active bootloader protection !
Simple flash with this tool with the option "clean and lock critical"
Works for me !

I'm in your same situation
Exactly the same situation here... Waiting for a solution without losing warranty.
I think if your bootloader is not unlocked, the only possible solution left is to shorting the test points on motherboard. Those who have warranty can return the unit for claim. Yet another mess up from Xiaomi and this will be my last phone from them.

I can understand that. I will claim warranty because its new and i dont want do that test point thing.
on private i would buy and recommend xiaomi anyways but if you want these hardware for some enterprise things then better not.
Iam out of this Thread now but if you want talk here some more feel free.. maybe somebody can bring a solution for all you guys who face this problem but i think its not possible without a open BL or the TestPoint Method.
Regards and have a nice day
Hi. I'm with locked bootloader. I received new January update. No change - stock variant updated to Pie. So it's safe to update or waiting for new one? Mi A2 4/64 micron ram
Yesterday, I was going to lock my bootloader to cell my Nokia 8 cuz' I needed money. Being the noobie that I'm I didn't have my unlock key saved anywhere. and couldn't get a new one because the stupid Bootloader unlock app doesn't work on Pie. I did know that locking the bootloader doesn't require a key. So I just went with it without remembering that I still had TWRP instead of stock boot img installed. So when I locked the bootloader the phone booted into a screen similar to the unlocked Bootloader warning screen. But it said "Your Device is corrupt. It can't be Trusted and will not boot." Instead. So now I have locked bootloader with TWRP that I can't boot into. I still can boot into fastboot mode but I can't do much Because LoCkEd BooTlOaDeR. The only sulotion is to unlock the bootloader with an unlock key Which I don't have and flash stock boot. So please help. You'll be literally saving my life. This is my first thread ever on the internet so forgive me If I made any mistakes:laugh:
EDIT: I took my phone to the service centre near me and they were able to fix it

Hello! I have the same problem! (((You were not interested in what exactly or how you should do to correct the error? And how much money did you get for repair?
Well you can use original OST not NOST and flash signed images (.NB1) without unlocking bootloader.

Only with service point authorization as far as I know. OST (and NOST by extension) usually show you a login prompt when you launch them. Service Points login to a server that generates a temporary unlock key, which allows OST to reflash the partitions. With the proper authorization, even NOST could flash .qlz files (as long as the images inside are official and signed) with a locked bootloader.
Since we don't have service point permission we have to patch the tool to ignore it (both NOST and the hacked OST). It will still try to request the temporary key, fail, and pass an empty value to the bootloader. To get the bootloader to accept the following flashing commands, you have to unlock it.
Hi Guys
Need your assistance, its a complete mess here.
I found android 14 pre releases in developer options -> DSU Loader -> Installed GSM+ARM64. Thought it will install android 14 pre release (Saw in one of youtube video -
).
Post restart phone it went to system has been destoryed.
1. OEM unlock option was not checked (Bootloader locked)
2. Only booting in fastboot mode.
3. Flashing through EDL/ Flash Auth not working.
I can only think of unlocking bootloader may fix this issue but problem is bootloader is locked. Can't unlock it because oem unlock is not enabled under developer options.
Please help me bypass OEM unlock check so that I can unlock bootloader & probably flashing TWRP or Orange recovery will fix the problem
Thank you
This tutorial is for those who have the bootloader unlocked (see the video at 3 minutes 38, the padlock is open).
What did you want to do?
The phone is bricked, nothing to do with the locked bootloader, see a Xiaomi repair center.
Hi
I missed that it is for unlocked bootloader.
So if bootloader is locked, it should not update the partitions & if so it should roll back to original miui if it fails.
But instead it bricked my phone.
So if someone can help me unlock bootloader I can try flashing recovery & then rom.
Or suggest better option. service center people asked to replace motherboard.
hi!
If there is any way to fix it, unfortunately it is paid.

It is imperative to unlock the bootloader with a xiaomi account where unlocking is authorized and associated with your smartphone. Without it, not worth it...
So unlock the bootloader and apply one of those countless FAQs that you'll find on XDA or youtube.
For me, settled in an hour.
Good luck,
