Question about Unlock bootloader - Xiaomi Mi A2 / 6X Questions & Answers

I have a serval question about unlocking Mi A2 Bootloader
1. Do unlock bootloader void xiaomi's hardware warranty?
I have heard that xiaomi still have hardware warranty even you unlock bootloader is that true?
2. Do unlock bootloader have permanent message on screen while boot even I relock bootloader?
my previous device Moto M have message bootloader has been unlocked while boot, and this message won't disappear even I relock bootloader.
3. To unlock Mi A2, just fastboot oem unlock is it enough?
I have heard that xiaomi need to wait 15 days to get a special tool from xiaomi to unlock bootloader. but in XDA post look like fastboot oem unlock is enough. it so weird...
Thank you for your answer.

1. No, you will not void warranty
2. When you unlock bootloader you will have message on your screen, after you lock it again, there is no message, everything is like stock.
3. fastboot oem unlock and fastboot flashing unlock_critical those two commands are enough
If you have xiaomi phone with miui, than you need to wait for unlock approval, around 72 hours, maybe less maybe more, it depends... When you have android one device, you do not need to wait, you can unlock your phone instantly.

Re-lock bootloader

Hi,
Some time ago I unlocked the bootloader and rooted my device. Didn't know it was possible to root without unlocking the bootloader (yes, i'm quite new to rooting etc.). Now my phone has a defective headphone-jack and I need to send it on repair. Anyone know how to re-lock the bootloader so I still have the warranty?
Currently running sLIM 4.8 by Wajk.
Use flashtool
Thanks, but it says on Sony's website that the phone stays unlocked even after using flash tool?
Code:
fastboot oem lock
Never done it in Sony phone but most of HTC, Nexus and few other brands I'm locking just with this command.

Your warranty will be lost with or without Huawei ID

Sure but what Huawei does'nt know..
And you could lock the Bootloader in case of a warranty defect...
As far as I know when you requested the bootloader unlock code - there is no way to return...
Well, requesting the code doesn't mean that you actually applied it. So if you send in your phone with a locked bootloader for repair, you should be fine.
Yea coming from LG G4 and we had to request an unlock.bin from them to flash. Requesting the unlock won't void warranty, I'm guessing it is the same as LG where it will have a "Bootloader Unlocked" message on splash screen once unlock.bin is applied.
To those of you who have unlocked, is this the case, and I have read somewhere you can relock bootloader too. Does this then have a "bootloader relocked" message or anything? Or is it if it is locked you can't tell it was ever unlocked?

Yes, I successfully relocked and do not receive any warnings during boot. I don't know about Huaweis, but Sony Xperias that had been unlocked and relocked have a modified TA partition and can therefore be identified.
Ok would be nice if anyone can confirm that it is possible to relock the bootloader in case of warranty ?
Thanks guys!
Is there anyway too unlock de bootloader now that huawei stop giving the code??

Warranty Question for treble support.

i have an Honor 9 Lite LLD-L22A. I want to unlock bootloader and flash AOSP Treble ROM. Will it void my warranty?
Of course. Unlocking bootloader voids the warranty.
Can you relock the bootloader?
"Relock bootloader" what's that about ?
If you have bad rom and relock bootloader - you can pay 15€ to dc-unlocker for bootloader unlocking.
ONLY if "bootloader unlocked" AND "FRP unlock" you can self-repair your phone !
you go to huawei-page for bootloader-unlock-code : your phone is registered as "bootloader opened" !
and relock bootloader nothing help !
all user must self-question "what will i do with my phone ?"
if the answer "i will modify" then you need bootloader unlock AND your warranty is minimized. NOT zero : minimized.
Flash GSI without TWRP
As mentioned in this post https://www.xda-developers.com/flash-generic-system-image-project-treble-device/. Flash GSI without TWRP will it also void warranty??
You still need to unlock the bootloader to flash ANYTHING. So yes, that way also voids the warranty.

Bootloader locked automatically

My redmi 4x (santoni) have twrp installed and I it is running on miui pro rom. But it's bootloader locking automatically after enabling usb debugging and switching off the phone. I can't boot into recovery and system, can only boot into fastboot mode, and I have to use mi flash tool to unlock bootloader again.
If someone face this problem, is there any solution of this. Please reply.
Thank you.
Bootloader can only be locked on all available official MIUI ROM, it can not be locked on modified MIUI versions.
There is no way that it'll get locked by itself by turning on USB Debugging and switching off phone. to lock unlocked bootloader one has to clean flash from Mi flash tools and needs to select lock bootloader before flashing.
I don't know how are you able to unlock bootloader on Mi flash tools because to unlock it official way one will need Mi unlock tool with permission from xiaomi(depending on region)
First make sure you are not on fake MIUI if so then flash official one through mi flash tools and then unlock it by mi unlock tools.
Once it is unlocked as i said earlier there is no way that it will get locked itself unless you choose to lock via mi flash tools.
about unlocking again
sorry for mistake, I have to use mi unlock tool again with my mi account signed in to unlock the bootloader again. And can't unlock by fastboot command "fastboot oem unlock".

I still do not get it what exact issue you have and what version of MIUI you are on.
You are saying you are on MIUI Pro and that confirms bootloader is unlocked and now you are saying

I have a similar issue and came across this thread, usb debugging suddenly stopped working, it was working perfectly till yesterday. So when I went to developer options, I saw that the OEM unlocking option is clickable now ( it had remained grayed out ever since I unlocked the bootloader ). The Mi Unlock status option tells me that phone is locked. Toggling usb debugging is not making it work. When I restart the phone, I definitely see the unlocked padlock icon on the boot screen. So I am not sure what is going on. also, magisk is working fine.
In the screenshot you can see that it shows the device is locked. But from the status bar you can make out that exposed is working. I'll have to get another device though to get a picture of the padlock icon though.

Toggle OEM unlock enabled doesn´t mean that the device is unlocked, it only means that the bootloader can be unlocked, there is other item just lines after to check it; Mi Unlock status, enter to it and confirm it.
Also, you can confirm the bootloader status through fastboot with fastboot oem device-info

Yea as I mentioned, the mi unlock status tells me that phone is locked.
Just check via fastboot, and it shows that phone is unlocked.
So do I just believe fastboot, or wait a month and then try to again unlock the bootloader via the mi unlock tool?

You said "In the screenshot you can see that it shows the device is locked" but unfortunately the screenshot didn´t reveal that, I wonder, what exactly it says in the Mi Unlock status apart.
In older days, users share an aboot image, this served to unlock bootloader automatically without make the official process to unlock it, it could be that you flashed the official stock images, and it got re-locked. Anyway, we don´t know what happened with the fastboot command or with the Mi Unlock status section, so no respond to those points.
For the part you say to wait a certain time, definitely, no, the bootloader process is not monitored any more, for older devices, they can be unlocked instantly.

My phone is about a month old, so it does tell me to wait. Contradictory screenshots attached below. After the boot unlock, I did flash flash a magisk edited boot.img and vbmeta.img to disable it. If I remember correctly though it was fine after that.

Unlock FRP Honor 9 Lite (LLD-L31)

How to unlock FRP on Honor 9 Lite? Software version is the latest 9.1.0.158, where many tricks like Hangouts no longer work. Apparently the only trick that works is unlock with test point? With what software and how does the unlocking perform?
whilst I have been trying to unlock the bootloader, I accidently unlocked frp (now red "unlocked"). I don't remember how I did it; i unlocked OEM and then randomly tried all possible testpoints; no software used. Installed all the drivers.

I have a LLD-L31 and trying to short the testpoint, no success after hours of trying.
