Like on the Nexus One, I would like to know if there is a way to root the phone without unlocking the bootloader. I have apps on my phone that I cant currently have wiped, so therefore cant unlock the bootloader. However if i can root, I can backup that specific app, and then unlock the bootloader, install roms etc, and then restore my app. Any help would be great, thanks.

As of now there is no way to root without unlocking the bootloader
unlock bootloader : fastboot oem unlock
lock bootloader : fastboot oem lock

He cant do a full wipe though is what he is saying
Bite the bullet and redo all your apps.
I cant bite the bullet, as the app has data that has to be remotely pushed to my phone and the people who do that are away for Christmas, Is there no way at all to root without unlocking the bootloader.
I was at work when i entered a bootloop. I was doing nothing special maybe using the camera. I was bootloader unlocked rooted on latest twrp and on the latest official dirty unicorn I think 10.4 and everything was fine.
After the bootloop started I tried entering recovery in which it only boot loops. I can only access the bootloader screen. I Can see my device in fastboot devices.
I think my next step is to flash some Google factory images in fastboot. But I was wondering if my device be encrypted with fingerprints and a pin will affect it because I've ran into a problem last year when flashing a new version of TWRP it asked for passcode when one was not set.
I'd love to be able to recover some of my data but I guess if it's Encrypted that is not a chance, so I guess I will fastboot Flash the original images.
Is there going to be any problems when I try to flash Nexus images while it is encrypted with a passcode, Any suggestions?
Yeah, standard answer here is to flash the fastboot images. It'll be wiping/overwriting system and vendor so you shouldn't have any issues with the previous fingerprints. It'd be a good idea to wipe data once you get into TWRP afterwards but I wouldn't worry about wiping/formatting userdata.

I flashed the stock images mtc19x and its bootlooping to hell. Is it time for me to call Google? To see if I can get a new one I bought it in November when it came out

It's worth trying the latest (MTC20F) images first. And if that doesn't work I'd try formatting userdata too.

Hey man, you think i can relock the bootloader with only access to the bootloader screen. I can't access anything accept for bootloader.... It won't boot up or go into recovery.
I'm returning it for rma

I did that exactly. It returned with the list of commands
Fastboot flashing lock
I think it can't. When I type devices it comes back with a serial number and I could even flash boot system and all that from the system image. But when I type fastboot flashing lock it acts like it can't complete that request. Hopefully Huawei or Google won't care if my bootloader is unlocked although i did Flash the factory images and unrooted it

I'm holding off twrp + bootloader unlock because I want to be able to undo in case I need to use my warranty. Is twrp/bootloader unlock reversible? Many thanks
Yes. Flash complete stock everything, boot into bootloader, connect to PC, and "fastboot oem lock".
Is it sure that it works??I have a A2017G and i have open BL and a B29 Custom Rom and i want back to Lock Bootloader

Yup! I've done it plenty of times. You do need to format the data partition though. This could mean that it'll wipe out even your internal storage, so back that up as well!
Im on stock and then i go to edl and then i type fastboot oem lock but nothing happend

Locking it again is good for when you want to sell the device or send it in for warranty repair.

Yeah, the unlock procedure is the same as before. If you didn't restore the original boot image before the relock, then it's just a matter of booting into fastboot and unlocking the device. Note that this will cause your data to be wiped as well!
If you restore your boot.bin backup file from when your device was locked, does this lock the bootloader? "fastboot oem lock", "fastboot flashing lock" nor "fastboot oem device-info" does nothing for me. Is there any other way to check if your bootloader has been relocked?
Thanks

Hi there,
Were you ever able to re-lock your bootloader on your A2017G?
I just want root for now but understand that I'll need to unlock the bootloader first. Before doing that, I want to make sure I can re-lock the bootloader if needed.
Thanks for letting us know!

Guys/Gals, it is seriously as simple as using the fastboot command in reverse. I've done it a few times already with mine.
If you used the following to unlock....
fastboot devices
fastboot oem unlock
.....then you can use the following commands to relock
fastboot devices
fastboot oem lock
fastboot devices is not necessary, but I do it to make sure the devices is being recognized by ADB/FASTBOOT

Thanks for the answer.
But there are a few files to flash before using that command according to this thread.
Doesn't anything need to be flashed again (e. g. stock files or anything)?
Correct, but you would have already flashed those in order to use the unlock command in the first place.
Are you trying to relock on marshmallow or nougat?

My phone is only a few days old. I'm debating whether to keep it or not (considering the Mate 9, but the price is not the same - love the form factor and bigger screen though - sound won't be the same and I think I'll miss the MiPop button on the Axon (never thought that would happen )).
I'm on the latest MM (B10 - the A2017G model).
Following the mentioned thread, I got to the point of installing TWRP (the signed version), only to realize that besides making backups, there is not much else I can do with that without unlocking the bootloader. I really just wanted to flash supersu and install adaway fro the time being until development matured for this phone (maybe also play around with viper - had great results on my LG G4).
HI, I get the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock". Any way to fix this?
Guys, can anyone help me? I really need to lock the bootloader!
How can I fix the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock"?
I'm on MM B11 Stock.

Hi Guys,
The Axon 7 Model A2017U I just purchased has the bootloader locked and it is running LineageOS 14.1 - 2018032-Nightly-axon7. I need to relock the bootloader and get back to the stock MiFavor rom so that I can send the phone to ZTE for repair. Can you please explain to a newb in some detail how to achieve that.
Thank you.
I did not see this posted anywhere, nor do I see it on Google's Factory Image website/instructions.
Based on testing... When re-locking the bootloader, "fastboot flashing lock" does NOT seem to lock the critical partition.
After following Google's steps to a T and locking the regular bootloader, It was indeed locked. I even attempted to lock regular bootloader again, and received a message stating it was already locked. Bootloader screen also says everything is locked. All is fine and dandy, right?
For ****s and giggles, I tried performing "fastboot flashing lock_critical". It indeed asked me if I wanted to lock the critical partition. After re-locking critical, I was not able to lock critical again. Safe to say, critical does not get re-locked when re-locking regular bootloader.
Safe to say... to re-lock the bootloader completely, you probably want to perform "fastboot flashing lock_critical" then perform the regular "fastboot flashing lock".

Oh believe me, I agree. I thought it was strange re-locking the critical isn't part of Googles Instructions. Not even sure if it matters, but just an extra security precaution
Thank You very much for the heads up. Saved me a headache
So the process for stock and locked would be to install a factory image to wipe and bring back to stock, fastboot flashing lock_critical, and fastboot flashing lock?

Hmmmm what about if you are worried about theft. You can still wipe the phone and login with another account can't you with the bootloader unlocked? Where as the phone will always be tied to the last google account logged in if the bootloader is locked, making the phone useless to sell even overseas. I could be wrong though.
When re-locking my bootloader on my Pixel 2 XL, I only needed to enter "fastboot flashing lock_critical" first. When I entered "fastboot flashing lock" afterwards, this error was returned:
FAILED (remote: ' Device already : locked!')
Seems you only need one step not both. My device is now 100% stock and bootloader is locked and ready for RMA.

Clean fastboot the factory and let it wipe your device. Then factory reset, then lock the bootloader. You must be 100% stock before you lock it down my friend :good:

If data is wiped once I flash the factory image. Why would I need to factory reset it? Your wisdom is appreciated.

Hello Guys,
I am trying to relock the bootloader of MiA1 but if I type command- "fastboot oem unlock" then my mobile cause stuck on bootloop. The same thing also happens with AIO Tool.
So please help me if anyone knows how to relock bootloader again? And also let me know whether unlocking bootloader affect warranty or not?
I know one method to lock bootloader that is, you can install stock ROM by mi flash tool but I need to install magisk and that require to unlock bootloader and if I unlocked once then unable to relock again.
The command in fastboot is fastboot oem lock
Have you done some modifications to the stock boot.img file, such as using magisk or something else?

Not sure if I understood correctly, but it seems that you want to have Magisk + TWRP + locked bootloader. That is simply not possible. For locked bootloader you must have stock ROM (no root, in fact absolutely no modification).

Bootloader lock is like a door.
If its open you can put nice things like magisk, root, modification like custom rom and kernel.
Now if you try to relock it it won't lock until and unless you take all the modifications out.
Hope this helps.
If you need technical information just let me know
flash stock boot.img and then probably you will be able to lock bootloader. I have done the same way.

With Nougat i flashed stock image selecting "save user data" and i had bootloader relocked without losing data. Root and twrp were gone. I don't know if it is so with Oreo.
So you need TWRP and Magisk root but want a locked bootloader? That just isn't a possible combination.
To install TWRP, you need unlocked bootloader.
If you need root and TWRP, you need to leave the bootloader unlocked.
You can't have both worlds bro. If you unlock and install Magisk and other stuff, you simply can't relock bootloader. That's why you get bootloop

Some people might say yes some might say no.
It depends on manufacturer.
OEMs don't explicitly say that it won't void your warranty.
So its grey area.
I am going to email Xiaomi about this and update this thread when i get reply.
Had various experiences with unlocked bootloader. So better to follow safe path.
Edit: Called xiaomi helpline two times.
1st said it will void warranty
2nd said it won't.

That's just what he said it to you. I got two responses.
Support representatives aren't authorised to send you sms or mail.
If there's an issue with your device (Unlocked BL) and you took it to service center. They might say out of warranty due to bootloader unlocking and what would be your reply to that?
Support representatives said it won't void warranty.
You can't back it up with anything since you dont have any proof of that conversation.
So unless it is written somewhere by xiaomi. Words are just words.
Is it possible to unlock the bootloader, root, make some minor modifications (activation of camera api, copying fm radio apk to system folder, etc), unroot, and finally relock (flashing stock boot.img before, of course) ?

Short answer:no.
Long answer: locked bootloader must have stock system and boot partition. Stock boot image will boot only unmodified system partition. However you can have bank and streaming apps with Magisk - use systemless modifications and magisk hide feature.
